INTRODUCTION  
Dear customer!  
Congratulations on your choice to buy a Husqvarna product! Husqvarna is based on a tradition that dates back to 1689, when the  
Swedish King Karl XI ordered the construction of a factory on the banks of the Huskvarna River, for production of muskets. The  
location was logical, since water power was harnessed from the Huskvarna River to create the water-powered plant. During over  
300 years of continuous operation, the Husqvarna factory has produced a lot of different products, from wood stoves to modern  
kitchen appliances, sewing machines, bicycles, motorcycles etc. In 1956, the first motor driven lawn mowers appeared, followed  
by chain saws in 1959, and it is within this area Husqvarna is working today.  
Today Husqvarna is one of the leading manufacturers in the world of forest and garden products, with quality as our highest priority.  
We develop, manufacture and market high quality motor driven products for forestry and gardening as well as for building and  
construction industry.  
Your purchase gives you access to professional help with repairs and service whenever this may be necessary. If the retailer who  
sells your machine is not one of our authorized dealers, ask for the address of your nearest servicing dealer.  
It is our wish that you will be satisfied with your product and that it will be your companion for a long time. Think of this operators  
manual as a valuable document.By following itscontent (using, service, maintenance etc) the life span and the second-hand value  
of the machine can be extended. If you ever lend or sell this machine, make sure that the borrower or buyer gets the operators  
manual, so they will also know how to properly maintain and use it.  
Thank you for using a Husqvarna product.  
Husqvarna AB has a policy of continuous product development and therefore reserves the right to modify the design and  
appearance of products without prior notice.

of non-authorized accessories or  
Never use any accessories other than those recommended  
in this manual. See instructions under the headings Cutting  
equipment and Technical data.  
replacement parts.  
CAUTION! Always wear protective glasses or a face visor to  
reduce the risk of injury from thrown objects. A chain saw is  
capable of throwing objects, such as wood chips, small  
pieces of wood, etc, at great force.This can result in serious  
injury, especially to the eyes.  
WARNING! A chain saw is a dangerous tool  
if used carelessly or incorrectly and can  
cause serious, even fatal injuries. It is very  
important that you read and understand the  
contents of this operator’s manual.  
!
WARNING! Running an engine in a confined  
or badly ventilated area can result in death  
due to asphyxiation or carbon monoxide  
poisoning.  
!
WARNING! The inside of the muffler contain  
chemicals that may be carcinogenic. Avoid  
contact with these elements in the event of a  
!
damaged muffler.  
WARNING! Faulty cutting equipment or the  
wrong combination of bar and saw chain  
increases the risk of kickback! Only use the  
bar/saw chain combinations we recommend,  
and follow the filing instructions. See  
instructions under the heading Technical  
data.  
!
WARNING! Long term inhalation of the  
engine’s exhaust fumes, chain oil mist and  
dust from sawdust can represent a health  
risk.

circumstances interfere with pacemakers.To  
reduce the risk of serious or fatal injury, we  
recommend persons with pacemakers to  
consult their physician and the pacemaker  
manufacturer before operating this machine.  
It is not possible to cover every conceivable situation you can  
face when using a chain saw. Always exercise care and use  
your common sense. Avoid all situations which you consider  
to be beyond your capability. If you still feel uncertain about  
operating procedures after reading these instructions, you  
should consult an expert before continuing. Do not hesitate to  
contact your dealer or us if you have any questions about the  
use of the chain saw. We will willingly be of service and  
provide you with advice as well as help you to use your chain  
saw both efficiently and safely. Attend a training course in

GENERAL SAFETY PRECAUTIONS  
chain saw usage if possible.Your dealer, forestry school or  
your library can provide information about which training  
materials and courses are available.  
Fire Extinguisher and Shovel  
Generally clothes should be close-fitting without restricting  
your freedom of movement.  
IMPORTANT! Sparks can come from the muffler, the bar  
and chain or other sources. Always have fire extinguishing  
tools available if you should need them. Help prevent forest  
fires.  
Machine s safety equipment  
Work is constantly in progress to improve the design and  
technology - improvements that increase your safety and  
efficiency. Visit your dealer regularly to see whether you can  
benefit from new features that have been introduced.  
In this section the machine’s safety features and their function  
are explained. For inspection and maintenance see  
instructions under the heading Checking, maintaining and  
servicing chain saw safety equipment. See instructions under  
the heading, What is what?, to find where these parts are  
located on your machine.  
Personal protective equipment  
The life span of the machine can be reduced and the risk of  
accidents can increase if machine maintenance is not carried  
out correctly and if service and/or repairs are not carried out  
professionally. If you need further information please contact  
your nearest servicing dealer.  
WARNING! Most chain saw accidents  
happen when the chain touches the  
operator.You must use approved personal  
protective equipment whenever you use the  
machine. Personal protective equipment  
cannot eliminate the risk of injury but it will  
reduce the degree of injury if an accident  
does happen. Ask your dealer for help in  
choosing the right equipment.  
!
WARNING! Never use a machine with  
defective safety components. Safety  
equipment must be inspected and  
maintained. See instructions under the  
heading Checking, maintaining and  
!
servicing chain saw safety equipment. If  
your machine does not pass all the checks,  
take the saw to a servicing dealer for repair.  
Chain brake and front hand guard  
Your chain saw is equipped with a chain brake that is  
designed to stop the chain if you get a kickback. The chain  
brake reduces the risk of accidents, but only you can prevent  
them.  
Approved protective helmet  
Hearing protection  
Take care when using your saw and make sure the kickback  
zone of the bar never touches any object.  
Protective goggles or a visor  
Gloves with saw protection  
Trousers with saw protection  
Boots with saw protection, steel toe-cap and non-slip sole  
Always have a first aid kit nearby.

GENERAL SAFETY PRECAUTIONS  
The chain brake (A) can either be activated manually (by  
To release the chain brake pull the front hand guard  
your left hand) or automatically by the inertia release  
mechanism.  
backwards, towards the front handle.  
A
Kickback can be very sudden and violent. Most kickbacks  
are minor and do not always activate the chain brake. If  
this happens you should hold the chain saw firmly and not  
let go.  
The brake is applied when the front hand guard (B) is  
pushed forwards or when the right-hand brake trigger (E)  
is pushed up and forwards.  
B
E
The way the chain brake is activated, either manually or  
automatically by the inertia release mechanism, depends  
on the force of the kickback and the position of the chain  
saw in relation to the object that the kickback zone of the  
bar strikes.  
This movement activates a spring-loaded mechanism that  
tightens the brake band (C) around the engine drive  
system (D) (clutch drum).  
If you get a violent kickback while the kickback zone of the  
bar is farthest away from you the chain brake is designed  
to be activated by the inertia in the kickback direction.  
The front hand guard is not designed solely to activate the  
chain brake. Another important feature is that it reduces  
the risk of your left hand hitting the chain if you lose grip of  
the front handle.  
If the kickback is less violent or the kickback zone of the  
bar is closer to you the chain brake is designed to be  
activated manually by the movement of your left hand.  
The chain brake must be engaged when the chain saw is  
started to prevent the saw chain from rotating.  
In the felling position the left hand is in a position that  
makes manual activation of the chain brake impossible.  
With this type of grip, that is when the left hand is placed  
so that it cannot affect the movement of the front hand  
guard, the chain brake can only be activated by the inertia  
action.  
Use the chain brake as a ”parking brake” when starting  
and when moving over short distances, to reduce the risk  
of moving chain accidentally hitting your leg or anyone or  
anything close by.

GENERAL SAFETY PRECAUTIONS  
Will my hand always activate the chain  
Chain catcher  
brake during a kickback?  
The chain catcher is designed to catch the chain if it snaps or  
jumps off. Replace it if necessary with an aluminium chain  
catcher (is available as spare part).This should not happen if  
the chain is properly tensioned (see instructions under the  
heading Assembly) and if the bar and chain are properly  
serviced and maintained (see instructions under the heading  
General working instructions).  
No. It takes a certain force to move the hand guard forward. If  
your hand only lightly touches the front guard or slips over it,  
the force may not be enough to trigger the chain brake.You  
should also maintain a firm grip of the chain saw handles  
while working.If you do and experience a kickback, your hand  
may never leave the front handle and will not activate the  
chain brake, or the chain brake will only activate after the saw  
has swung around a considerable distance. In such  
instances, the chain brake might not have enough time to stop  
the saw chain before it touches you.  
There are also certain positions in which your hand cannot  
reach the front hand guard to activate the chain brake; for  
example, when the saw chain is held in felling position.  
Will my inetria activated chain brake  
always activate during kickback in the  
event of a kickback?  
Right hand guard  
No. First your brake must be in working order. Testing the  
brake is simple, see instructions under the heading Checking,  
maintaining and servicing chain saw safety equipment. We  
recommend you do before you begin each work session.  
Second the kickback must be strong enough to activate the  
chain brake.If the chain brake is too sensitive it would activate  
all the time which would be a nuisance.  
Apart from protecting your hand if the chain jumps or snaps,  
the right hand guard stops branches and twigs from  
interfering with your grip on the rear handle.  
Will my chain brake always protect me  
from injury in the event of a kickback?  
No. First, the chain brake must be in working order to provide  
the intended protection. Second, it must be activated during  
the kickback as described above to stop the saw chain.Third,  
the chain brake may be activated but if the bar is too close to  
you the brake might not have enough time to slow down and  
stop the chain before the chain saw hits you.  
Vibration damping system  
Your machine is equipped with a vibration damping system  
that is designed to reduce vibration and make operation  
easier.  
Only you and proper working technique can eliminate  
kickback and its danger.  
Throttle lockout  
The throttle lockout is designed to prevent accidental  
operation of the throttle control. When you press the lock (A)  
(i.e.when you grasp the handle) it releases the throttle control  
(B). When you release the handle the throttle control and the  
throttle lockout both move back to their original positions.This  
arrangement means that the throttle control is automatically  
locked at the idle setting.  
The machines vibration damping system reduces the transfer  
of vibration between the engine unit/cutting equipment and  
the machines handle unit. The body of the chain saw,  
including the cutting equipment, is insulated from the handles  
by vibration damping units.

This section describes how to choose and maintain your  
cutting equipment in order to:  
lead to circulatory damage or nerve damage  
in people who have impaired circulation.  
!
Contact your doctor if you experience  
symptoms of overexposure to vibration.  
Such symptoms include numbness, loss of  
feeling, tingling, pricking, pain, loss of  
strength, changes in skin colour or  
condition.These symptoms normally appear  
in the fingers, hands or wrists.These  
symptoms may be increased in cold  
temperatures.  
Reduce the risk of kickback.  
Reduce the risk of the saw chain breaking or jumping off  
the bar.  
Obtain optimal cutting performance.  
Extend the life of cutting equipment.  
Avoid increasing vibration levels.  
General rules  
Stop switch  
Only use cutting equipment recommended by us!  
Use the stop switch to switch off the engine.  
See instructions under the heading Technical data.  
Keep the chain’s cutting teeth properly sharpened!  
Follow our instructions and use the recommended file  
gauge. A damaged or badly sharpened chain increases  
the risk of accidents.  
Muffler  
The muffler is designed to keep noise levels to a minimum and  
to direct exhaust fumes away from the user.  
WARNING! The exhaust fumes from the  
engine are hot and may contain sparks  
which can start a fire. Never start the  
machine indoors or near combustible  
material!  
Maintain the correct depth gauge setting! Follow our  
instructions and use the recommended depth gauge  
clearance. Too large a clearance increases the risk of  
kickback.  
!
In areas with a hot, dry climate there is a high risk of fires.  
These areas are sometimes subject to government rules  
requiring among other things the muffler must be equipped  
with an approved type of spark arrestor screen.  
Keep the chain properly tensioned! If the chain is slack  
it is more likely to jump off and lead to increased wear on  
the bar, chain and drive sprocket.  
Keep cutting equipment well lubricated and properly  
maintained! A poorly lubricated chain is more likely to  
break and lead to increased wear on the bar, chain and  
drive sprocket.  
CAUTION! The muffler gets very hot during and after use.  
This also applies during idling. Be aware of the fire hazard,  
especially when working near flammable substances and/  
or vapours.

be matched to the chain saw design.  
The only way to avoid kickback is to make sure that the  
kickback zone of the bar never touches anything.  
By using cutting equipment with ”built-in” kickback reduction  
and keeping the chain sharp and well-maintained you can  
reduce the effects of kickback.

!
Some terms that describe the bar and chain  
To maintain the safety features of the cutting equipment, you  
should replace a worn or damaged bar or chain with a bar and  
chain combinations recommended by Husqvarna. See  
instructions under the heading Technical Data for a list of  
replacement bar and chain combinations we recommend.  
Sharpening your chain and adjusting  
depth gauge setting  
General information on sharpening cutting teeth  
Bar  
Never use a blunt chain.When the chain is blunt you have  
to exert more pressure to force the bar through the wood  
and the chips will be very small. If the chain is very blunt it  
will produce wood powder and no chips or shavings.  
Length (inches/cm)  
A sharp chain eats its way through the wood and produces  
long, thick chips or shavings.  
Number of teeth on bar tip sprocket (T).  
Chain pitch (inches).The spacing between the drive links  
of the chain must match the spacing of the teeth on the bar  
tip sprocket and drive sprocket.  
The cutting part of the chain is called the cutter and  
consists of a cutting tooth (A) and the depth gauge (B).  
The cutters cutting depth is determined by the difference  
in height between the two (depth gauge setting).  
Number of drive links. The number of drive links is  
determined by the length of the bar, the chain pitch and  
the number of teeth on the bar tip sprocket.

GENERAL SAFETY PRECAUTIONS  
When you sharpen a cutting tooth there are four important  
factors to remember.  
Always file cutting teeth from the inside face. Reduce the  
pressure on the return stroke.File all the teeth on one side first,  
then turn the chain saw and file the teeth on the other side.  
1
Filing angle  
File all the teeth to the same length. When the length of  
the cutting teeth is reduced to 0.16 inch (4 mm) the chain  
is worn out and should be replaced.  
2
Cutting angle  
3
4
File position  
General advice on adjusting depth gauge setting  
When you sharpen the cutting tooth (A) the depth gauge  
setting (C) will decrease. To maintain optimal cutting  
performance the depth gauge (B) has to be filed down to  
achieve the recommended depth gauge setting. See  
instructions under the heading Technical data to find the  
correct depth gauge setting for your particular chain.  
Round file diameter  
It is very difficult to sharpen a chain correctly without the right  
equipment. We recommend that you use our file gauge. This  
will help you obtain the maximum kickback reduction and  
cutting performance from your chain.  
WARNING! The risk of kickback is increased  
if the depth gauge setting is too large!  
!
Adjustment of depth gauge setting  
See instructions under the heading Technical data for  
information about sharpening your chain.  
WARNING! Departure from the sharpening  
instructions considerably increases the risk  
of kickback.  
The cutting teeth should be newly sharpened before  
adjusting the depth gauge setting. We recommend that you  
adjust the depth gauge setting every third time you sharpen  
the cutting teeth.NOTE!This recommendation assumes that  
the length of the cutting teeth is not reduced excessively.  
!
Sharpening cutting teeth  
You will need a flat file and a depth gauge tool. We  
recommend that you use our depth gauge tool to acheive the  
correct depth gauge setting and bevel for the depth gauge.  
To sharpen cutting teeth you will need a round file and a file  
gauge. See instructions under the heading Technical data for  
information on the size of file and gauge that are  
recommended for the chain fitted to your chain saw.  
Place the depth gauge tool over the chain. Detailed  
information regarding the use of the depth gauge tool, will  
be found on the package for the depth gauge tool. Use the  
flat file to file off the tip of the depth gauge that protrudes  
through the depth gauge tool. The depth gauge setting is  
correct when you no longer feel resistance as you draw  
the file along the depth gauge tool.  
Check that the chain is correctly tensioned. A slack chain  
will move sideways, making it more difficult to sharpen  
correctly.

GENERAL SAFETY PRECAUTIONS  
Tensioning the chain  
Lubricating cutting equipment  
WARNING! Poor lubrication of cutting  
equipment may cause the chain to snap,  
which could lead to serious, even fatal  
!
injuries.  
WARNING! A slack chain may jump off the  
bar and cause serious or even fatal injury.  
!
Chain oil  
Chain oil must demonstrate good adhesion to the chain and  
also maintain its flow characteristics regardless of whether it  
is warm summer or cold winter weather.  
The more you use a chain the longer it becomes. It is  
therefore important to adjust the chain regularly to take up the  
slack.  
As a chain saw manufacturer we have developed an optimal  
chain oil which has a vegetable oil base. We recommend the  
use of our own oil for both maximum chain life and to minimise  
environmental damage. If our own chain oil is not available,  
standard chain oil is recommended.  
Check the chain tension every time you refuel. NOTE! A new  
chain has a running-in period during which you should check  
the tension more frequently.  
Tension the chain as tightly as possible, but not so tight that  
you cannot pull it round freely by hand.  
Never use waste oil! Using waste oil can be dangerous to  
you and damage the machine and environment.  
IMPORTANT! When using vegetable based saw chain oil,  
dismantle and clean the groove in the bar and saw chain  
before long-term storage. Otherwise there is a risk of the  
saw chain oil oxidizing, which will result in the saw chain  
becoming stiff and the bar tip sprocket jamming.  
Loosen the bar nuts that hold the clutch cover/chain brake.  
Use the combination spanner. Then tighten the bar nuts  
by hand as tight as you can.  
Filling with chain oil  
All our chain saws have an automatic chain lubrication  
system. On some models the oil flow is also adjustable.  
Raise the tip of the bar and stretch the chain by tightening  
the chain tensioning screw using the combination  
spanner. Tighten the chain until it does not sag from the  
underside of the bar.  
The saw chain oil tank and the fuel tank are designed so  
that the fuel runs out before the saw chain oil.  
However, this safety feature requires that you use the right  
sort of chain oil (if the oil is too thin it will run out before the  
fuel), and that you adjust the carburetor as recommended  
(a lean mixture may mean that the fuel lasts longer than  
the oil) and that you also use the recommended cutting  
equipment (a bar that is too long will use more chain oil).  
Use the combination spanner to tighten the bar nuts while  
lifting the tip of the bar at the same time. Check that you  
can pull the chain round freely by hand and that it does not  
sag from the underside of the bar.  
Checking chain lubrication  
Check the chain lubrication each time you refuel. See  
instructions under the heading Lubricating the bar tip  
sprocket.  
Aim the tip of the bar at a light coloured surface about 20  
cm (8 inches) away. After 1 minute running at 3/4 throttle  
you should see a distinct line of oil on the light surface.  
The position of the chain tensioning screw on our chain saws  
varies from model to model. See instructions under the  
heading What is what? to find out where it is on your model.

GENERAL SAFETY PRECAUTIONS  
If the chain lubrication is not working:  
Needle bearing lubrication  
Check that the oil channel in the bar is not obstructed.  
Clean if necessary.  
Both versions of sprockets have a needle bearing on the drive  
shaft, which has to be greased regularly (once a week).  
CAUTION! Use only high quality bearing grease or engine oil.  
See instructions under the heading Maintenance, Needle  
bearing lubrication.  
Check that the groove in the edge of the bar is clean.  
Clean if necessary.  
Checking wear on cutting equipment  
Check the chain daily for:  
Check that the bar tip sprocket turns freely and that the  
lubricating hole in the tip sprocket is not blocked. Clean  
and lubricate if necessary.  
Visible cracks in rivets and links.  
Whether the chain is stiff.  
Whether rivets and links are badly worn.  
Replace the saw chain if it exhibits any of the points above.  
We recommend you compare the existing chain with a new  
chain to decide how badly the existing chain is worn.  
If the chain lubrication system is still not working after carrying  
out the above checks and associated measures you should  
contact your servicing dealer.  
When the length of the cutting teeth has worn down to only  
0.16 inch (4 mm) the chain must be replaced.  
Chain drive sprocket  
The clutch drum is fitted with one of the following drive  
sprockets:  
A Spur sprocket (the chain sprocket is welded on the drum)  
B Rim sprocket (replaceable)  
Regularly check the degree of wear on the drive sprocket.  
Replace if wear is excessive. Replace the drive sprocket  
whenever you replace the chain.

GENERAL SAFETY PRECAUTIONS  
Bar  
Check regularly:  
Whether there are burrs on the edges of the bar. Remove  
these with a file if necessary.  
Whether the groove in the bar has become badly worn.  
Replace the bar if necessary.  
Whether the tip of the bar is uneven or badly worn. If a  
hollow forms on the underside of the bar tip this is due to  
running with a slack chain.  
To prolong the life of the bar you should turn it over daily.  
WARNING! Most chain saw accidents  
happen when the chain touches the  
operator.  
!
Wear personal protective equipment. See  
instructions under the heading Personal  
protective equipment.  
Do not tackle any job that you feel you are  
not adequately trained for. See instructions  
under the headings Personal protective  
equipment, How to avoid kickback, Cutting  
equipment and General working  
instructions.  
Avoid situations where there is a risk of  
kickback. See instructions under the  
heading Machine s safety equipment.  
Use the recommended protective equipment  
and check its condition. See instructions  
under the heading General working  
instructions.  
Check that all the chain saw safety features  
are working. See instructions under the  
headings General working instructions and

ASSEMBLY  
Tension the chain by turning the chain tensioning screw  
clockwise using the combination spanner. See instructions  
under the heading Tensioning the chain.  
Fitting the bar and chain  
WARNING! Always wear gloves, when  
working with the chain, in order to protect  
your hands from injury.  
!
Check that the chain brake is in disengaged position by  
moving the front hand guard towards the front handle.  
The chain is correctly tensioned when it does not sag from the  
underside of the bar, but can still be turned easily by hand.  
Hold up the bar tip and tighten the bar nuts with the  
combination spanner.  
Remove the bar nuts and remove the clutch cover (chain  
brake). Take off the transportation ring (A).  
When fitting a new chain, the chain tension has to be checked  
frequently until the chain is run-in. Check the chain tension  
regularly. A correctly tensioned chain ensures good cutting  
performance and long life.  
Note: If clutch cover is difficult to remove, replace bar nuts,  
engage brake and rerelease (an audible click will be heard if  
released properly).  
Fit the bar over the bar bolts. Place the bar in its rearmost  
position. Place the chain over the drive sprocket locate it in  
the groove on the bar. Begin on the top edge of the bar.  
Make sure that the edges of the cutting links are facing  
forward on the top edge of the bar.  
Fit the clutch cover and locate the chain adjuster pin in the  
hole in the bar. Check that the drive links of the chain fit  
correctly over the drive sprocket and that the chain is correctly  
located in the groove in the bar. Tighten the bar nuts finger  
tight.

FUEL HANDLING  
Mixing ratio  
Fuel  
1:50 (2%) for all engines.  
Note! The machine is equipped with a two-stroke engine and  
must always be run using a mixture of gasoline and two-  
stroke oil. It is important to accurately measure the amount of  
oil to be mixed to ensure that the correct mixture is obtained.  
When mixing small amounts of fuel, even small inaccuracies  
can drastically affect the ratio of the mixture.

Mixing  
Use good quality unleaded gasoline.  
CAUTION! Engines equipped with catalytic  
converters must be run on unleaded fuel mixtures.  
Leaded gasoline will destroy the catalytic converter and it  
will no longer serve its purpose. The green fuel cap on  
saws fitted with catalytic converters means that only  
unleaded gasoline can be used.  
The lowest recommended octane grade is 87  
((RON+MON)/2). If you run the engine on a lower octane  
grade than 87 so-called knocking can occur. This gives  
rise to a high engine temperature and increased bearing  
load, which can result in serious engine damage.  
When working with continuous high revs (e.g. limbing) a  
higher octane is recommended.  
Always mix the gasoline and oil in a clean container  
intended for fuel.  
Environment fuel  
Always start by filling half the amount of the gasoline to be  
used. Then add the entire amount of oil. Mix (shake) the  
fuel mixture. Add the remaining amount of gasoline.  
HUSQVARNA recommends the use of alkylate fuel or  
environmental fuel for four-stroke engines blended with two-  
stroke oil as set out below. Note that carburetor adjustment  
may be necessary when changing the type of fuel (see  
instructions under the heading Carburetor).  
Mix (shake) the fuel mixture thoroughly before filling the  
machine’s fuel tank.  
Do not mix more than one month’s supply of fuel at a time.  
Running-in  
If the machine is not used for some time the fuel tank  
should be emptied and cleaned.  
Avoid running at a too high speed for extended periods during  
the first 10 hours.  
Chain oil  
Two-stroke oil  
We recommend the use of special oil (chain oil) with good  
adhesion characteristics.  
For best results and performance use HUSQVARNA two-  
stroke engine oil, which is specially formulated for our air-  
cooled two stroke-engines.  
Never use two-stroke oil intended for water-cooled  
engines, sometimes referred to as outboard oil (rated  
TCW).  
Never use oil intended for four-stroke engines.  
Never use waste oil. This results in damage to the oil  
pump, the bar and the chain.  
It is important to use oil of the right grade (suitable  
viscosity range) to suit the air temperature.  
In temperatures below 32°F (0°C) some oils become too  
viscous. This can overload the oil pump and result in  
damage to the oil pump components.  
Contact your service agent when choosing chain oil.

FUEL HANDLING  
Fueling  
Fuel safety  
Never refuel the machine while the engine is running.  
Make sure there is plenty of ventilation when refuelling or  
mixing fuel (gasoline and 2-stroke oil).  
WARNING!Taking the following precautions,  
will lessen the risk of fire:  
Move the machine at least 10 ft (3 m) from the refuelling  
point before starting it.  
!
Do not smoke and do not place any hot  
objects in the vicinity of fuel.  
Always stop the engine and let it cool for a  
few minutes before refuelling.  
When refuelling, open the fuel cap slowly so  
that any excess pressure is released gently.  
Min. 3 m  
(10 ft)  
Tighten the fuel cap carefully after refuelling.  
Always move the machine away from the  
refuelling area before starting.  
Never start the machine:  
1
If you have spilled fuel or chain oil on the machine. Wipe  
off the spillage and allow remaining fuel to evaporate.  
Clean the area around the fuel cap. Clean the fuel and chain  
oil tanks regularly. The fuel filter must be replaced at least  
once a year. Contamination in the tanks causes malfunction.  
Make sure the fuel is well mixed by shaking the container  
before refuelling.The capacities of the chain oil tank and fuel  
tank are carefully matched.You should therefore always fill  
the chain oil tank and fuel tank at the same time.  
2
3
If you have spilled fuel on yourself or your clothes, change  
your clothes.Wash any part of your body that has come in  
contact with fuel. Use soap and water.  
If the machine is leaking fuel. Check regularly for leaks  
from the fuel cap and fuel lines.  
WARNING! Never use a machine with visible  
damage to the spark plug guard and ignition  
cable. A risk of sparking arises, which can  
cause a fire.  
!
Transport and storage  
Always store the chain saw and fuel so that there is no risk  
of leakages or fumes coming into contact with sparks or  
naked flames from electrical equipment, electric motors,  
relays/switches, boilers and the like.  
WARNING! Fuel and fuel vapor are highly  
flammable.Take care when handling fuel and  
chain oil. Be aware of the risks of fire,  
explosion and those associated with  
inhalation.  
!
Always store fuel in an approved container designed for  
that purpose.  
For longer periods of storage or for transport of the chain  
saw, the fuel and chain oil tanks should be emptied. Ask  
where you can dispose of waste fuel and chain oil at your  
local gas station.  
Ensure the machine is cleaned and that a complete  
service is carried out before long-term storage.  
The bar guard must always be fitted to the cutting  
attachment when the machine is being transported or in  
storage, in order to prevent accident contact with the  
sharp chain. Even a non-moving chain can cause serious  
cuts to yourself or persons you bump into with an exposed  
chain.  
Long-term storage  
Empty the fuel/oil tanks in a well ventilated area.Store the fuel  
in approved cans in a safe place. Fit the bar guard. Clean the  
machine. See instructions under the heading Maintenance  
schedule.

STARTING AND STOPPING  
Warm engine  
Starting and stopping  
Use the same procedure as for starting a cold engine but  
without setting the choke control in the choke position. The  
correct choke/start throttle setting is obtained by moving the  
choke control to the choke position and then pushing it in  
again.  
WARNING! Note the following before  
starting:  
!
The chain brake must be engaged when the  
chain saw is started to reduce the chance of  
contact with the moving chain during  
starting.  
Never start a chain saw unless the bar, chain  
and all covers are fitted correctly. Otherwise  
the clutch can come loose and cause  
personal injuries.  
Place the machine on firm ground. Make  
sure you have a secure footing and that the  
chain cannot touch anything.  
Starting  
Keep people and animals well away from the  
working area.  
Grip the front handle with your left hand. Hold the chain saw  
on the ground by placing your right foot through the rear  
handle. Pull the starter handle with your right hand and pull  
out the starter cord slowly until you feel a resistance (as the  
starter pawls engage) then pull firmly and rapidly.Never wrap  
the starter cord around your hand  
Cold engine  
Starting: The chain brake should be activated when starting  
the chain saw. Activate the chain brake by pushing the front  
hand guard forwards.  
CAUTION! Do not pull the starter cord all the way out and do  
not let go of the starter handle when the cord is fully extended.  
This can damage the machine.  
Ignition; choke: Set the choke control in the choke position.  
This should automatically set the stop switch to the start  
position.  
Start throttle: The correct choke/start throttle setting is  
obtained by moving the control to the choke position.  
Push in the choke control as soon as the engine fires and  
make repeated starting attempts. Immediately press and  
release the throttle when the engine starts. That will  
disengage the throttle latch.  
As the chain brake is still activated the engine must return to  
idling speed as soon as possible by disengaging the throttle  
latch in order to avoid unnecessery wear on the clutch  
assembly.  
If the machine is fitted with an air purge (A): Press the air  
purge repeatedly until fuel begins to fill the bulb. The bulb  
need not be completely filled.  
If the machine is fitted with a decompression valve (B): Press  
the valve to reduce the pressure in the cylinder and make  
starting easier.You should always use the decompression  
valve when starting the machine. Once the machine has  
started the valve will automatically return to its original setting.

should be on the rear handle, and the left hand on the front  
handle. All people, whether right or left handed, should  
use this grip. Use a firm grip with thumbs and fingers  
encircling the chain saw handles.  
WARNING! Long term inhalation of the  
engine’s exhaust fumes, chain oil mist and  
dust from sawdust can represent a health  
risk.  
!
Never start a chain saw unless the bar, chain and all  
covers are fitted correctly. See instructions under the  
heading Assembly. Without a bar and chain attached to  
the chain saw the clutch can come loose and cause  
serious injury.  
Stopping  
The engine is stopped by pushing the stop switch to the stop  
position.  
The chain brake should be activated when starting. Se  
instructions under the heading Start and stop.Do not drop  
start. This method is very dangerous because you may  
lose control of the saw.  
Never start the machine indoors. Exhaust fumes can be  
dangerous if inhaled.  
Observe your surroundings and make sure that there is no  
risk of people or animals coming into contact with the  
cutting equipment.

Make sure you can move and stand safely.Check the area  
around you for possible obstacles (roots, rocks, branches,  
ditches, etc.) in case you have to move suddenly. Take  
great care when working on sloping ground.  
IMPORTANT!  
This section describes basic safety rules for using a chain  
saw. This information is never a substitute for professional  
skills and experience. If you get into a situation where you  
feel unsafe, stop and seek expert advice. Contact your  
chain saw dealer, service agent or an experienced chain  
saw user. Do not attempt any task that you are not sure you  
can handle!  
Before using a chain saw you must understand the effects  
of kickback and how to avoid them. See instructions under  
the heading How to avoid kickback.  
Before using a chain saw you must understand the  
difference between cutting with the top and bottom edges of  
the bar. See instructions under the headings How to avoid  
kickback and Machine’s safety equipment.  
Wear personal protective equipment. See instructions

WORKING TECHNIQUES  
5
Take great care when cutting a tree that is under tension.  
Lack of concentration can lead to kickback if the kickback  
zone of the bar accidentally touches a branch, nearby tree  
or some other object.  
A tree that is under tension may spring back to its normal  
position before or after being cut. If you position yourself  
incorrectly or make the cut in the wrong place the tree may  
hit you or the machine and cause you to lose control. Both  
situations can cause serious personal injury.  
6
Before moving your chain saw switch off the engine and  
lock the chain using the chain brake. Carry the chain saw  
with the bar and chain pointing backwards. Fit a guard to  
the bar before transporting the chain saw or carrying it for  
any distance.  
Have control over the workpiece. If the pieces you intend  
to cut are small and light, they can jam in the saw chain  
and be thrown towards you. Even if this does not need to  
be a danger, you may be surprised and lose control of the  
saw. Never saw stacked logs or branches without first  
separating them. Only saw one log or one piece at a time.  
Remove the cut pieces to keep your working area safe.  
4
Never use the chain saw above shoulder height and  
avoid cutting with the tip of the bar. Never use the  
chain saw one-handed!  
Never carry or hang the saw by the trigger! This could  
damage the mechanism and disable the chain brake.  
7
When you put the chain saw on the ground, lock the saw  
chain using the chain brake and ensure you have a  
constant view of the machine.Switch the engine off before  
leaving your chain saw for any length of time.  
General rules  
5
In order to keep control of your saw, always maintain a firm  
foothold. Never work on a ladder, in a tree or on any other  
insecure support.  
1
If you understand what kickback is and how it happens  
then you can reduce or eliminate the element of surprise.  
By being prepared you reduce the risk.Kickback is usually  
quite mild, but it can sometimes be very sudden and  
violent.  
2
Always hold the chain saw firmly with your right hand on  
the rear handle and your left hand on the front handle.  
Wrap your fingers and thumbs around the handles.You  
should use this grip whether you are right-handed or left-  
handed.This grip minimizes the effect of kickback and lets  
you keep the chain saw under control. Do not let go of  
the handles!  
6
7
Always use a fast cutting speed, i.e. full throttle.  
Take great care when you cut with the top edge of the bar,  
i.e. when cutting from the underside of the object. This is  
known as cutting with a pushing chain. The chain tries to  
push the chain saw back towards the user.If the saw chain  
is jamming, the saw may be pushed back at you.  
3
Most kickback accidents happen during limbing. Make  
sure you are standing firmly and that there is nothing in  
the way that might make you trip or lose your balance.

WORKING TECHNIQUES

Unless the user resists this pushing force there is a risk  
There are five important factors you should  
consider before making a cut:  
that the chain saw will move so far backwards that only the  
kickback zone of the bar is in contact with the tree, which  
can lead to a kickback.  
1
Make sure the cutting equipment will not jam in the cut.  
2
Make sure the object you are cutting will not split.  
Cutting with the bottom edge of the bar, i.e. from the top of  
the object downwards, is known as cutting with a pulling  
chain. In this case the chain saw pulls itself towards the  
tree and the front edge of the chain saw body rests  
naturally on the trunk when cutting. Cutting with a pulling  
chain gives the operator better control over the chain saw  
and the position of the kickback zone.  
3
4
Make sure the chain will not strike the ground or any other  
object during or after cutting.  
Is there a risk of kickback?  
9
Follow the instructions on sharpening and maintaining  
your bar and chain. When you replace the bar and chain  
use only combinations that are recommended by us. See  
instructions under the headings Cutting equipment and  
Technical data.  
Basic cutting technique  
5
Do the conditions and surrounding terrain affect how  
safely you can stand and move about?  
WARNING! Never use a chain saw by holding  
it with one hand. A chain saw is not safely  
controlled with one hand. Always have a  
secure, firm grip around the handles with  
both hands.  
Two factors decide whether the chain will jam or the object  
that you are cutting will split: the first is how the object is  
supported before and after cutting, and the second is whether  
it is in tension.  
!
In most cases you can avoid these problems by cutting in two  
stages; from the top and from the bottom.You need to support  
the object so that it will not trap the chain or split during cutting.  
General  
Always use full throttle when cutting!  
Reduce the speed to idle after every cut (running the  
engine for too long at full throttle without any load, i.e.  
without any resistance from the chain during cutting, can  
lead to serious engine damage).  
IMPORTANT! If the chain jams in the cut: stop the engine!  
Don’t try to pull the chain saw free. If you do you may be  
injured by the chain when the chain saw suddenly breaks  
free. Use a lever to open up the cut and free the chain saw.  
Cutting from above = Cutting with a pulling chain.  
Cutting from below = Cutting with pushing chain.  
The following instructions describe how to handle the  
common situations you are likely to encounter when using a  
chain saw.  
Cutting with a pushing chain increases the risk of kickback.  
See instructions under the heading How to avoid kickback.  
Limbing  
When limbing thick branches you should use the same  
approach as for cutting.  
Terms  
Cutting = General term for cutting through wood.  
Limbing = Cutting branches off a felled tree.  
Cut difficult branches piece by piece.

WORKING TECHNIQUES  
The log is supported at one end. There is a high risk that it  
will split.  
Cutting  
WARNING! Never attempt to cut logs while  
they are in a pile or when a couple of logs  
are lying together. Such procedures  
drastically increase the risk of kickback  
which can result in a serious or fatal injury.  
!
Start by cutting from below (about 1/3 of the way through).  
Finish by cutting from above so that the two cuts meet.  
If you have a pile of logs, each log you attempt to cut should  
be removed from the pile, placed on a saw horse or runners  
and cut individually.  
Remove the cut pieces from the cutting area. By leaving them  
in the cutting area, you increase the risk for inadvertently  
getting a kickback, as well as increasing the risk of losing your  
balance while working.  
The log is supported at both ends. There is a high risk that  
the chain will jam.  
Start by cutting from above (about 1/3 of the way through).  
Finish by cutting from below so that the two cuts meet.  
Tree felling technique  
The log is lying on the ground.There is little risk of the chain  
jamming or the object splitting.However there is a risk that the  
chain will touch the ground when you finish the cut.  
Cut all the way through the log from above. Avoid letting the  
chain touch the ground as you finish the cut. Maintain full  
throttle but be prepared for what might happen.  
IMPORTANT! It takes a lot of experience to fell a tree.  
Inexperienced users of chain saws should not fell trees. Do  
not attempt any task beyond your experience level!  
If it is possible (can you turn the log?) stop cutting about 2/3  
of the way through the log.  
Safe distance  
The safe distance between a tree that is to be felled and  
anyone else working nearby is at least 2 1/2 tree lengths.  
Make sure that no-one else is in this ”risk zone” before or  
during felling.  
Turn the log and finish the cut from the opposite side.

WORKING TECHNIQUES  
Felling direction  
Clearing the trunk and preparing your retreat  
The aim is to fell the tree in a position where you can limb and  
cross-cut the log as easily as possible.You want it to fall in a  
location where you can stand and move about safely.  
Delimb the stem up to shoulder height.It is safer to work from  
the top down and to have the tree between you and the saw.  
Once you have decided which way you want the tree to fall  
you must judge which way the tree would fall naturally.  
Several factors affect this:  
Lean of the tree  
Bend  
Wind direction  
Arrangement of branches  
Weight of snow  
Remove any undergrowth from the base of the tree and check  
the area for obstacles (stones, branches, holes, etc.) so that  
you have a clear path of retreat when the tree starts to fall.  
Your path of retreat should be roughly 135 degrees away from  
the intended felling direction.  
Obstacles within the reach of the tree: for example, other  
trees, power lines, roads and buildings.  
Look for signs of damage and rot in the stem, this makes  
it more probably that the tree will break and start to fall  
before you expect it to.

Danger zone  
You may find you are forced to let the tree fall in its natural  
direction because it is impossible or dangerous to try to make  
it fall in the direction you first intended.  
Felling  
WARNING! Unless you have special training  
we advise you not to fell trees with a  
diameter larger than the bar length of your  
saw!  
Another very important factor, which does not affect the felling  
direction but does affect your safety, is to make sure the tree  
has no damaged or dead branches that might break off and  
hit you during felling.  
!
The main point to avoid is letting the tree fall onto another tree.  
It is very dangerous to remove a trapped tree and there is high  
accident risk. See instructions under the heading Freeing a  
tree that has fallen badly.  
Felling is done using three cuts. First you make the directional  
cuts, which consist of the top cut and the bottom cut, then you  
finish with the felling cut. By placing these cuts correctly you  
can control the felling direction very accurately.  
Directional cuts  
To make the directional cuts you begin with the top cut. Stand  
to the right of the tree and cut on the pull stroke.  
IMPORTANT! During critical felling operations, hearing  
protectors should be lifted immediately when sawing is  
completed so that sounds and warning signals can be  
heard.

WORKING TECHNIQUES  
Next make the bottom cut so that it finishes exactly at the end  
The felling hinge controls the direction that the tree falls in.  
of the top cut.  
All control over the felling direction is lost if the felling hinge is  
too narrow or non-existent, or if the directional cuts and felling  
cut are badly placed.  
The directional cuts should run 1/4 of the diameter through  
the trunk and the angle between the top cut and bottom cut  
should be 45°.  
When the felling cut and directional cut are complete the tree  
should start to fall by itself or with the aid of a felling wedge or  
breaking bar.  
The line where the two cuts meet is called the directional cut  
line. This line should be perfectly horizontal and at right  
angles (90°) to the chosen felling direction.  
Felling cut  
We recommend that you use a bar that is longer than the  
diameter of the tree, so that you can make the felling cut and  
directional cuts with single cutting strokes. See instructions  
under the heading Technical data section to find out which  
lengths of bar are recommended for your saw.  
The felling cut is made from the opposite side of the tree and  
it must be perfectly horizontal. Stand on the left side of the  
tree and cut on the pull stroke.  
Make the felling cut about 1.5-2 inches (3-5 cm) above the  
bottom directional cut.  
There are methods for felling trees with a diameter larger than  
the bar length. However these methods involve a much  
greater risk that the kickback zone of the bar will come into  
contact with the tree.  
Finish the felling cut parallel with the directional cut line so that  
the distance between them is at least 1/10 of the trunk  
diameter. The uncut section of the trunk is called the felling  
hinge.

WORKING TECHNIQUES  
General advice:  
Freeing a tree that has fallen badly  
Position yourself so that you will be clear of the tree or branch  
when the tension is released.  
Freeing a ”trapped tree”  
It is very dangerous to remove a trapped tree and there is high  
accident risk.  
Never try to fell the tree that is trapped.  
Make one or more cuts at or near the point of maximum  
tension. Make as many cuts of sufficient depth as necessary  
to reduce the tension and make the tree or branch break at  
the point of maximum tension.  
Never cut straight through a tree or branch that is in  
tension!  
If you must cut across tree/limb, make two to three cuts, one  
inch apart, one to two inches deep.  
Never work in the risk zone of the hanging trapped tree.  
Continue to cut deeper until tree/limb bends and tension is  
released.  
Cut tree/limb from outside the bend, after tension has been  
released.  
The safest method is to use a winch.

How to avoid kickback  
WARNING! Kickback can happen very  
suddenly and violently; kicking the chain  
saw, bar and chain back at the user. If this  
!
Portable  
happens when the chain is moving it can  
cause very serious, even fatal injuries. It is  
vital you understand what causes kickback  
and that you can avoid it by taking care and  
using the right working technique.  
Cutting trees and branches that are in tension  
What is kickback?  
Preparations:Work out which side is in tension and where the  
point of maximum tension is (i.e. where it would break if it was  
bent even more).  
The word kickback is used to describe the sudden reaction  
that causes the chain saw and bar to jump off an object when  
the upper quadrant of the tip of the bar, known as the kickback  
zone, touches an object.  
Decide which is the safest way to release the tension and  
whether you are able to do it safely. In complicated situations  
the only safe method is to put aside your chain saw and use  
a winch.

WORKING TECHNIQUES  
Kickback always occurs in the cutting plane of the bar.  
Normally the chain saw and bar are thrown backwards and  
upwards towards the user. However, the chain saw may move  
in a different direction depending on the way it was being used  
when the kickback zone of the bar touched the object.  
Kickback only occurs if the kickback zone of the bar touches  
an object.  
Limbing  
WARNING! A majority of kickback accidents  
occur during limbing. Do not use the  
kickback zone of the guide bar. Be extremely  
!
cautious and avoid contacting the log, other  
limbs or objects with the nose of the guide  
bar. Be extremely cautious of limbs under  
tension.They can spring back toward you  
and cause loss of control resulting in injury.  
Make sure that you can stand and move about safely.Work on  
the left side of the trunk. Work as close as possible to the  
chain saw for maximum control. If possible, let the weight of  
the chain saw rest on the trunk.  
Keep the trunk between you and the chain saw as you move  
along the trunk.  
Cutting the trunk into logs

MAINTENANCE  
Basic settings and running in  
General  
The basic carburetor settings are adjusted during testing at  
the factory. Avoid running at a too high speed for extended  
periods during the first 10 hours.  
The user must only carry out the maintenance and service  
work described in this manual.  
IMPORTANT! Any maintenance other than that described in  
this manual must be carried out by your servicing dealer  
(retailer).  
CAUTION! If the chain rotates while idling the T-screw  
must be turned anti-clockwise until the chain stops.  
Rec. idle speed: 2700 rpm  
Fine adjustment  
Carburetor adjustment  
When the machine has been ”run-inthe carburetor should be  
finely adjusted. The fine adjustment should be carried out  
by a qualified person. First adjust the L-jet, then the idling  
screw T and then the H-jet.  
Due to existing environmental and emissions legislation your  
chain saw is equipped with movement limiters on the  
carburetor adjuster screws. These limit the adjustment  
possibilities to a maximum of a 1/2 turn.  
Conditions  
H
L
Before any adjustments are made the air filter should be  
clean and the cylinder cover fitted. Adjusting the  
carburetor while a dirty air filter is in use will result in a  
leaner mixture next time the filter is cleaned.This can give  
rise to serious engine damage.  
1/2  
1/2  
Do not attempt to adjust the L and H jets beyond  
either stop as this could cause damage.  
Your Husqvarna product has been designed and  
manufactured to specifications that reduce harmful emissions.  
Now start the machine according to the starting  
instructions and let it warm up for 10 minutes.  
Place the machine on a flat surface so that the bar points  
away from you and so that the bar and chain do not come  
into contact with the surface or other objects.  
Function  
The carburetor governs the engine’s speed via the throttle  
control. Air and fuel are mixed in the carburetor. The air/  
fuel mixture is adjustable. Correct adjustment is essential  
to get the best performance from the machine.  
Low speed jet L  
Turn the low speed jet L clockwise until it stops. If the engine  
accelerates poorly or idles unevenly, turn the low speed jet L  
anticlockwise until good acceleration and idling are achieved.  
The satisfactory operation of a catalytic converter  
depends, among other factors, on the correct adjustment  
of the carburetor. Carefully follow the instructions below,  
using a tachometer as an aid.  
Fine adjustment of the idling speedT  
The setting of the carburetor means that the engine is  
adapted to local conditions, for example, the climate,  
altitude, fuel and the type of 2-stroke oil.  
Adjust the idle speed with the T-screw. If it is necessary to re-  
adjust, turn theT-screw clockwise while the engine is running,  
until the chain starts to rotate. Then turn counter-clockwise  
until the chain stops. A correctly adjusted idle speed setting  
occurs when the engine runs smoothly in every position. It  
should also be good margin to the rpm when the chain starts  
to rotate.  
The carburetor has three adjustment controls:  
- L = Low speed jet  
- H = High speed jet  
- T = Idle adjustment screw  
WARNING! Contact your servicing dealer, if  
the idle speed setting cannot be adjusted so  
that the chain stops at idle. Do not use the  
chain saw until it has been properly adjusted  
or repaired.  
H

!
High speed jet H  
At the factory the engine is adjusted at sea level. When  
working at a high altitude or in different weather conditions,  
temperatures and atmospheric humidity, it may be  
T
The L and H-jets are used to adjust the supply of fuel to  
match the rate that air is admitted, which is controlled with  
the throttle. If they are screwed clockwise the air/fuel ratio  
becomes leaner (less fuel) and if they are turned anti-  
clockwise the ratio becomes richer (more fuel). A lean  
mixture gives a higher engine speed and a rich mixture  
gives a lower engine speed.  
necessary to make minor adjustments to the high speed jet.  
CAUTION! If the high speed jet is screwed in too far, it  
may damage the piston/cylinder.  
When test run at the factory, the high speed jet is set so that  
the engine satisfies the applicable legal requirements at the  
same time as achieving maximum performance. The  
carburetor’s high speed jet is then locked using a limiter cap  
in the fully screwed out position. The limiter cap limits the  
potential to adjust the high speed jet to at most half a turn.  
The T-screw regulates the throttle setting at idle speed. If  
the T-screw is turned clockwise this gives a higher idle  
speed; turning it anti-clockwise gives a lower idle speed.

MAINTENANCE  
Checking the inertia brake release  
Correctly adjusted carburetor  
When the carburetor is correctly adjusted the machine  
accelerates without hesitation and the machine 4-cycles a  
little at max. speed. It is also important that the chain does not  
rotate at idle. If the L-jet is set too lean it may cause starting  
difficulties and poor acceleration.If the H-jet is set too lean the  
machine will have less power, poor acceleration and could  
suffer damage to the engine.  
With the engine turned off, hold the chain saw over a stump  
or other firm object. Let go of the front handle so that the bar  
drops towards the stump as the chain saw rotates around the  
rear handle.  
Checking,maintaining and servicing  
chain saw safety equipment  
Note! All servicing and repair work on the machine requires  
special training. This is especially true of the machines  
safety equipment. If your machine fails any of the checks  
described below we recommend you to contact our  
servicing dealer.  
When the bar hits the stump the brake should be applied.  
Chain brake and front hand guard  
Checking brake band wear  
Brush off any wood dust, resin and dirt from the chain brake  
and clutch drum. Dirt and wear can impair operation of the  
brake.  
Checking the right-hand brake trigger  
Check that the right hand guard is not damaged and that there  
are no visible defects, such as cracks.  
Regularly check that the brake band is at least 0.024 inch  
(0.6 mm) thick at its thinnest point.  
Push the trigger up and forwards to check that it moves freely  
and is securely hinged to the clutch cover.  
Checking the front hand guard  
Make sure the front hand guard is not damaged and that there  
are no visible defects such as cracks.  
Never carry or hang the saw by the trigger! This could  
damage the mechanism and disable the chain brake.  
Move the front hand guard forwards and back to make sure it  
moves freely and that it is securely anchored to the clutch  
cover.

MAINTENANCE  
Checking the brake trigger  
Chain catcher  
Place the chain saw on firm ground and start it.Make sure the  
chain does not touch the ground or any other object. See the  
instructions under the heading Start and stop.  
Check that the chain catcher is not damaged and is firmly  
attached to the body of the chain saw. Replace it if necessary  
with an aluminium chain catcher (is available as spare part).  
Grasp the chain saw firmly, wrapping your fingers and thumbs  
around the handles.  
Right hand guard  
Apply full throttle and activate the chain brake by tilting your  
left wrist forward onto the front hand guard. Do not let go of  
the front handle. The chain should stop immediately.  
Check that the right hand guard is not damaged and that there  
are no visible defects, such as cracks.  
Throttle lockout  
Vibration damping system  
Make sure the throttle control is locked at the idle setting  
when the throttle lockout is released.  
Regularly check the vibration damping units for cracks or  
deformation.  
Press the throttle lockout and make sure it returns to its  
original position when you release it.  
Make sure the vibration damping units are securely attached  
to the engine unit and handle unit.  
Stop switch  
Check that the throttle control and throttle lockout move  
freely and that the return springs work properly.  
Start the engine and make sure the engine stops when you  
move the stop switch to the stop setting.  
Start the chain saw and apply full throttle. Release the throttle  
control and check that the chain stops and remains stationary.  
If the chain rotates when the throttle control is in the idle  
position you should check the carburetor idle adjustment.

Muffler  
Starter  
WARNING! When the recoil spring is wound  
up in the starter housing it is under tension  
and can, if handled carelessly, pop out and  
cause personal injury.  
!
Never use a machine that has a faulty muffler.  
Care must be exercised when replacing the  
return spring, starter cord or the drive disc  
spring. Wear protective glasses and  
protective gloves.  
Changing a broken or worn starter cord  
Regularly check that the muffler is securely attached to the  
machine.  
Loosen the screws that hold the starter against the  
crankcase and remove the starter.  
Some mufflers are equipped with a special spark arrestor  
screen. If your machine has this type of muffler, you should  
clean the screen at least once a week.This is best done with  
a wire brush. A blocked screen will cause the engine to  
overheat and may lead to serious damage.  
Pull out the cord approx. 30 cm (12 inches) and hook it  
into the notch in the rim of the pulley. Release the recoil  
spring by letting the pulley rotate slowly backwards.  
Note! The screen must be replaced if it is damaged. If the  
screen is blocked the machine will overheat and this will  
cause damage to the cylinder and piston. Never use a  
machine with a muffler that is in poor condition. Never use a  
muffler if the spark arrestor screen is missing or  
defective.  
345e:  
Undo the bolt in the centre of the pulley and remove the  
drive disc, drive disc spring and the pulley. Insert and  
secure a new starter cord in the starter pulley. Wind  
approx. 3 turns of the starter cord on the starter pulley. Fit  
the starter pulley so that the end of the recoil spring hooks  
into the starter pulley.Now assemble the drive disc spring,  
drive disc and the bolt in the centre of the pulley. Carry the  
starter cord through the hole in the starter housing and the  
starter handle. Tie a good knot on the starter cord.  
The muffler is designed to reduce the noise level and to direct  
the exhaust gases away from the operator.The exhaust gases  
are hot and can contain sparks, which may cause fire if  
directed against dry and combustible material.  
A muffler equipped with a catalytic converter significantly  
reduces the amount of hydrocarbons (HC), nitrogen oxides  
(NO) and aldehydes in the exhaust fumes. Carbon monoxide  
(CO), which is poisonous and odorless, is not however  
reduced! Consequently, never work in an enclosed or badly  
ventilated area. Good air circulation should always prevail  
when working in snowy hollows, ravines or in confined  
conditions.

The air filter must be regularly cleaned to remove dust and dirt  
in order to avoid:  
Carburettor malfunctions  
Starting problems  
Recoil spring (A)  
Lift up the starter pulley. See instructions under the  
heading Changing a broken or worn starter cord.  
Remember that the recoil spring is coiled under tension in  
the starter housing.  
Loss of engine power  
Unnecessary wear to engine parts  
Excessive fuel consumption.  
Remove the cassette with the recoil spring from the  
starter.  
Remove the air filter after taking off the air filter cover.When  
refitting make sure that the air filter seals tightly against the  
filter holder. Clean the filter by brushing or shaking it.  
Lubricate the recoil spring with light oil. Fit the cassette  
with recoil spring in the starter. Fit the starter pulley and  
tension the recoil spring.  
The filter can be cleaned more thoroughly by washing it in  
water and detergent.  
An air filter that has been in use for a long time cannot be cleaned  
completely.The filter must therefore be replaced with a new one at  
regular intervals. A damaged air filter must always be replaced.  
A HUSQVARNA chain saw can be equipped with different  
types of air filters according to working conditions, weather,  
season, etc. Contact your dealer for advice.

MAINTENANCE  
Spark plug  
Needle bearing lubrication  
The spark plug condition is influenced by:  
The clutch drum has a needle bearing on the output shaft.  
This needle bearing must be lubricated regularly (once a  
week).  
Incorrect carburetor adjustment.  
An incorrect fuel mixture (too much or incorrect type of  
oil).  
When lubricating, remove the clutch cover by loosening the  
two bar nuts. Lay the saw on its side with the clutch drum  
upwards.  
A dirty air filter.  
Lubrication involves engine oil dripping into the centre of the  
clutch drum as it rotates.  
These factors cause deposits on the spark plug electrodes,  
which may result in operating problems and starting  
difficulties.  
If the machine is low on power, difficult to start or runs poorly  
at idle speed: always check the spark plug first before taking  
any further action. If the spark plug is dirty, clean it and check  
that the electrode gap is 0.020 inch (0.5 mm).The spark plug  
should be replaced after about a month in operation or earlier  
if necessary.  
Adjustment of the oil pump  
Note! Always use the recommended spark plug type! Use of  
the wrong spark plug can damage the piston/cylinder. Check  
that the spark plug is fitted with a suppressor.  
(346XP/353)  
The oil pump is adjustable. Adjustments are made by turning  
the screw using a screwdriver or combination spanner. The  
machine is supplied from the factory with the screw set to  
position 2.Turning the screw clockwise will reduce the oil flow  
and turning the screw anti-clockwise will increase the oil flow.  
Lubricating the bar tip sprocket  
Lubricate the bar tip sprocket each time you refuel. Use the  
special grease gun and a good quality bearing grease.

MAINTENANCE  
Cooling system  
Heated handles  
(346XPG, 353G)  
On models with the model code XPG/G both the front handle  
bar and the rear handle are equipped with electrical heating  
coils.These are supplied with electricity from a generator built  
into the chain saw.  
To keep the working temperature as low as possible the  
machine is equipped with a cooling system.  
The cooling system consists of:  
1

Electrical carburetor heating  
2
1
(346XPG, 353G)  
If this chain saw is marked with Carburetor Heating then it is  
equipped with an electrically heated carburettor. The  
electrical heating prevents icing in the carburettor. A  
thermostat regulates heating so that the carburettor always  
has the correct working temperature.  
Clean the cooling system with a brush once a week, more  
often in demanding conditions. A dirty or blocked cooling  
system results in the machine overheating which causes  
damage to the piston and cylinder.  
Note! The cooling system on a chain saw with catalytic  
converter must be cleaned daily.This is particularly important  
on chain saws with catalytic converters, because the higher  
exhaust temperature requires efficient cooling of the engine  
and the catalytic converter unit.  
Winter use  
Running problems can occur when using the machine in the  
cold and snowy conditions caused by:  
Too low engine temperature.  
”Air Injection” centrifugal cleaning  
Icing of the air filter and carburetor.  
Centrifugal cleaning means the following: All air to the  
carburetor passes through the starter. Dirt and dust is pushed  
out by the cooling fan.  
Special measures are therefore often required:  
Partly mask the air inlet on the starter to increase the  
working temperature of the engine.  
Preheat the intake air to the carburetor by using the heat  
from the cylinder.  
IMPORTANT! In order to maintain operation of the centrifugal  
cleaning system it must be regularly maintained.Clean the air  
intake to the starter, the fins on the flywheel, the space around  
the flywheel, inlet pipe and carburetor compartment.

345e: Before usage a hole is made in the cylinder cover and  
a winter flap is fitted (see illustration below).  
346XP, 353: The cylinder cover is designed so it can be  
adjusted for running in cold weather.  
Twist the winter flap so that preheated air from the cylinder  
can pass into the carburetor space preventing icing of the air  
filter, etc.  
For temperatures below -5°C (23°F) and/or in snow  
conditions there is also:  
a special cover (A) for the starter housing  
a winter plug (B) for the air nozzle that is fitted as shown.  
These reduce the flow of cooling air and prevent large  
amounts of snow from being sucked into the carburetor  
space.  
For further information see assembly instructions for the  
winter kit.  
CAUTION! When the winter plug is fitted the winter flap must  
be open!  
IMPORTANT! If the temperature rises above -5°C (23°F) or  
0°C (32°F) respectively the machine MUST be restored to  
its normal set-up. Otherwise there is a risk of overheating,  
which can cause severe engine damage.

TECHNICAL DATA  
Recommended original and replacement bar and chain combinations  
Following is a list of recommended cutting equipment for the Husqvarna chain saw models 345e TrioBrake, 346XP TrioBrake and  
353 TrioBrake. The combinations of power head, bar and chain have been investigated in accordance with the kickback and  
vibration requirements of ANSI B 175.1–2000.  
The guide bar nose radius is determined by either the maximum number of teeth in the nose sprocket or the corresponding  
maximum nose radius of a solid bar.  
The following list is the chain saw manufacturers recommendations. There may be other combinations available, which will also  
achieve kickback reduction.  
As we are listing the maximum guide bar nose radius, you may use a guide bar with smaller nose radius than in our list. For guide  
bars of the same length, all sprocket-nose guide bars of the same pitch and having the same number of sprocket teeth may be  
considered to have equivalent kickback energy. A hard nose bar having the same length and nose radius as a sprocket-nose bar  
may be considered to have equivalent or less kickback energy than the sprocket-nose bar.  
Bar and chain combinations  
Low kickback saw chain is a chain which has only met the kickback performance requirements of ANSI B 175.1 safety requirements  
for gasoline powered chain saws when tested on the representative sample of chain saws below 3.8 cu. in. specified in ANSI 175.1.  
We recommend that you as a replacement use the listed chains or "Low kickback saw chains" which are available at your dealer.

AMERICAN STANDARD SAFETY PRECAUTIONS  
Other safety precautions  
Safety precautions for chain saw  
users  
WARNING! Do not operate a chain saw with  
(ANSI B 175.1-2000 Annex C)  
one hand! Serious injury to the operator,  
helpers, bystanders or any combination of  
these persons may result from one-handed  
operation. A chain saw is intended for two-  
handed use.  
!
Kickback safety precautions  
WARNING! Kickback may occur when the  
nose or tip of the guide bar touches an  
object, or when the wood closes in and  
pinches the saw chain in the cut.  
Do not operate a chain saw when you are fatigued.  
!
Use safety footwear; snug-fitting clothing, protective gloves,  
and eye, hearing and head protection devices.  
Tip contact in some cases may cause a  
lightning fast reverse reaction, kicking the  
guide bar up and back towards the operator.  
Use caution when handling fuel. Move the chain saw at least  
10 feet (3 m) from the fueling point before starting the engine.  
Do not allow other persons to be near the chain saw when  
starting or cutting with the chain saw. Keep bystanders and  
animals out of the work area.  
Pinching the saw chain along the top of the  
guide bar may push the guide bar rapidly  
back towards the operator.  
Do not start cutting until you have a clear work area, secure  
footing and a planned retreat path from the falling tree.  
Either of these reactions may cause you to  
lose control of the saw which could result in  
serious personal injury.  
Keep all parts of your body away from the saw chain when the  
engine is running.  
Do not rely exclusively upon the safety  
devices built into your saw. As a chain saw  
user, you should take several steps to keep  
your cutting jobs free from accident or  
injury.  
Before you start the engine, make sure that the saw chain is  
not contacting anything.  
Carry the chain saw with the engine stopped, the guide bar  
and saw chain to the rear, and the muffler away from your  
body.  
With a basic understanding of kickback, you can reduce or  
eliminate the element of surprise. Sudden surprise  
contributes to accidents.  
Do not operate a chain saw that is damaged, improperly  
adjusted, or not completely and securely assembled. Be sure  
that the saw chain stops moving when the throttle control  
trigger is released.  
Keep a good firm grip on the saw with both hands, the right  
hand on the rear handle, and the left hand on the front handle,  
when the engine is running. Use a firm grip with thumbs and  
fingers encircling the chain saw handles. A firm grip will help  
you reduce kickback and maintain control of the saw. Don’t let  
go.  
Shut off the engine before setting the chain saw down.  
Use extreme caution when cutting small size brush and  
saplings because slender material may catch the saw chain  
and be whipped toward you or pull you off balance.  
Make sure that the area in which you are cutting is free from  
obstacles. Do not let the nose of the guide bar contact a log,  
branch, or any other obstacle which could be hit while you are  
operating the saw.  
When cutting a limb that is under tension be alert for  
springback so that you will not be struck when the tension in  
the wood fibers is released.  
Keep handles dry, clean and free of oil or fuel mixture.  
Operate the chain saw only in well-ventilated areas.  
Cut at high engine speeds.  
Do not overreach or cut above shoulder height.  
Do not operate a chain saw in a tree unless you have been  
specifically trained to do so.  
Follow manufacturer’s sharpening and maintenance  
instructions for the saw chain.  
Do not operate a chain saw above shoulder height.  
Only use replacement bars and chains specified by the  
manufacturer or the equivalent.  
All chain saw service, other than the items listed in the  
operator’s/owner’s safety and maintenance instructions,  
should be performed by competent chain saw service  
personnel.(For example, if improper tools are used to remove  
the flywheel or if an improper tool is used to hold the flywheel  
in order to remove the clutch, structural damage to the  
flywheel could occur and subsequently cause the flywheel to  
burst.)  
When transporting your chain saw, use the appropriate guide  
bar guard.  
Note: This Annex is intended primarily for the consumer or  
occasional user.
