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.

GENERAL SAFETY PRECAUTIONS  
Boots with saw protection, steel toe-cap and non-slip  
Always use common sense  
sole  
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 chain saw usage if  
possible.Your dealer, forestry school or your library can  
provide information about which training materials and  
courses are available.  
Always have a first aid kit nearby.  
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  
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.  
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.  
Work is constantly in progress to improve the design and

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.  
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.  
Take care when using your saw and make sure the  
kickback zone of the bar never touches any object.

GENERAL SAFETY PRECAUTIONS  
The chain brake (A) can either be activated manually  
To release the chain brake pull the front hand guard  
(by your left hand) or automatically by the inertia  
backwards, towards the front handle.  
release mechanism.  
The brake is applied when the front hand guard (B) is  
pushed forwards.  
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.  
This movement activates a spring-loaded mechanism  
that tightens the brake band (C) around the engine  
drive system (D) (clutch drum).  
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.  
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 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 chain brake must be engaged when the chain  
saw is started to prevent the saw chain from rotating.  
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.  
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.  
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.

GENERAL SAFETY PRECAUTIONS  
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.  
Will my hand always activate the chain  
brake during a kickback?  
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.  
Chain catcher  
The chain catcher is designed to catch the chain if it  
snaps or jumps off.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).  
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?  
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.  
Right hand guard  
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.  
Only you and proper working technique can eliminate  
kickback and its danger.

GENERAL SAFETY PRECAUTIONS  
Vibration damping system  
Your machine is equipped with a vibration damping  
system that is designed to reduce vibration and make  
operation easier.  
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!  
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.  
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.  
Cutting hardwoods (most broadleaf trees) creates more  
vibration than cutting softwoods (most conifers). Cutting  
with cutting equipment that is blunt or faulty (wrong type  
or badly sharpened) will increase the vibration level.  
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.  
WARNING! Never use a saw without a  
muffler, or with a damaged muffler. A  
!
damaged muffler may substantially  
increase the noise level and the fire  
hazard. Keep fire fighting equipment  
handy. If a spark arrestor screen is  
required in your area, never use the saw  
without or with a broken spark arrestor  
screen.  
WARNING! Overexposure to vibration  
can 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.  
Obtain optimal cutting performance.  
Extend the life of cutting equipment.  
Avoid increasing vibration levels.

Use the stop switch to switch off the engine.  
General rules  
Only use cutting equipment recommended by us!  
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.

GENERAL SAFETY PRECAUTIONS  
WARNING! Any contact with a rotating  
saw chain can cause extremely serious  
injuries.  
!
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.  
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.  
Bar  
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.  
Length (inches/cm)  
Number of teeth on bar tip sprocket (T).  
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.  
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.  
Cutting equipment designed to reduce  
kickback  
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.  
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.  
Bar groove width (inches/mm). The groove in the bar  
must match the width of the chain drive links.  
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.  
Bar  
The smaller the tip radius the lower the chance of  
kickback.  
Chain oil hole and hole for chain tensioner. The bar  
must be matched to the chain saw design.  
Chain  
A chain is made up of a number of links, which are  
available in standard and low-kickback versions.  
IMPORTANT! No saw chain design eliminates the  
danger of kickback.

Sharpening your chain and adjusting  
depth gauge setting  
General information on sharpening cutting teeth  
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.  
See instructions under the heading Technical data for  
information about sharpening your chain.  
A sharp chain eats its way through the wood and  
produces long, thick chips or shavings.  
WARNING! Departure from the  
sharpening instructions considerably  
!
increases the risk of kickback.  
Sharpening cutting teeth  
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).  
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.  
When you sharpen a cutting tooth there are four important  
factors to remember.

GENERAL SAFETY PRECAUTIONS  
Check that the chain is correctly tensioned. A slack  
You will need a flat file and a depth gauge tool. We  
chain will move sideways, making it more difficult to  
sharpen correctly.  
recommend that you use our depth gauge tool to  
acheive the correct depth gauge setting and bevel for  
the depth gauge.  
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.  
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.  
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.  
Tensioning the chain  
General advice on adjusting depth gauge setting  
WARNING! A slack chain may jump off  
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.  
the bar and cause serious or even fatal  
injury.  
!
The more you use a chain the longer it becomes. It is  
therefore important to adjust the chain regularly to take up  
the slack.  
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.  
WARNING! The risk of kickback is  
increased if the depth gauge setting is  
!
too large!  
Adjustment of depth gauge setting  
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.  
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.  
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.

GENERAL SAFETY PRECAUTIONS  
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.  
Lubricating cutting equipment  
WARNING! Poor lubrication of cutting  
equipment may cause the chain to snap,  
!
which could lead to serious, even fatal  
injuries.  
Chain oil  
If the chain lubrication is not working:  
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.  
Check that the oil channel in the bar is not obstructed.  
Clean if necessary.  
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.  
Never use waste oil! Using waste oil can be dangerous  
Check that the groove in the edge of the bar is clean.  
Clean if necessary.  
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.  
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.  
Filling with chain oil  
All our chain saws have an automatic chain lubrication  
system. On some models the oil flow is also  
adjustable.  
If the chain lubrication system is still not working after  
carrying out the above checks and associated measures  
you should contact your servicing dealer.  
The saw chain oil tank and the fuel tank are designed  
so that the fuel runs out before the saw chain oil.

GENERAL SAFETY PRECAUTIONS  
Chain drive sprocket  
Check regularly:  
Whether there are burrs on the edges of the bar.  
Remove these with a file if necessary.  
The clutch drum is fitted with one of the following drive  
sprockets:  
A
Spur sprocket (the chain sprocket is welded on the  
drum)  
Whether the groove in the bar has become badly  
worn. Replace the bar if necessary.  
B

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.  
Needle bearing lubrication  
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.  
To prolong the life of the bar you should turn it over  
daily.

ASSEMBLY  
Tension the chain by turning the chain tensioning screw  
Fitting the bar and chain  
clockwise using the combination spanner. See  
instructions under the heading Tensioning the 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.  
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.  
Note: If clutch cover is difficult to remove, replace bar  
nuts, engage brake and rerelease (an audible click will be  
heard if released properly).  
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  
1:50 (2%) for all engines.  
Fuel  
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.  
Always mix the gasoline and oil in a clean container  
intended for 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.  
When working with continuous high revs (e.g.limbing)  
a higher octane is recommended.  
Environment fuel  
Mix (shake) the fuel mixture thoroughly before filling  
the machine’s fuel tank.  
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).  
Do not mix more than one month’s supply of fuel at a  
time.  
If the machine is not used for some time the fuel tank  
should be emptied and cleaned.  
Running-in  
Chain oil  
Avoid running at a too high speed for extended periods  
during the first 10 hours.  
We recommend the use of special oil (chain oil) with  
good adhesion characteristics.  
Two-stroke oil  
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.

Fueling  
Move the machine at least 10 ft (3 m) from the  
refuelling point before starting it.  
WARNING! Taking the following  
precautions, will lessen the risk of fire:  
!
Do not smoke and do not place any hot  
objects in the vicinity of fuel.  
1
Never start the machine:  
Always stop the engine and let it cool for  
a few minutes before refuelling.  
If you have spilled fuel or chain oil on the machine.  
Wipe off the spillage and allow remaining fuel to  
evaporate.  
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.  
When refuelling, open the fuel cap slowly  
so that any excess pressure is released  
gently.

Tighten the fuel cap carefully after  
refuelling.  
If the machine is leaking fuel. Check regularly for  
leaks from the fuel cap and fuel lines.  
Always move the machine away from the  
refuelling area before starting.  
WARNING! Never use a machine with  
visible damage to the spark plug guard  
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.  
!
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.  
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.  
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.  
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  
Starting and stopping  
A
B
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.  
Warm engine  
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.  
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.  
Keep people and animals well away from  
the working area.  
Starting  
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.  
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  
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.  
Primer bulb: 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.  
Decompression valve: 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.  
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.

STARTING AND STOPPING  
Note! Pull the front hand guard towards the front handle.  
The chain brake is now disengaged.Your saw is ready for  
use.  
Always hold the saw with both hands. The right hand  
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 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.  
The engine is stopped by pushing the stop switch to the  
stop position.  
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.

Do not use the machine in bad weather, such as  
dense fog, heavy rain, strong wind, intense cold, etc.  
Working in bad weather is tiring and often brings  
added risks, such as icy ground, unpredictable felling  
direction, etc.  
Check that all parts of the chain saw are tightened  
correctly and that they are not damaged or missing.  
Check that the chain catcher is in place and not  
damaged.  
3
Take great care when removing small branches and  
avoid cutting bushes (i.e.cutting many small branches  
at the same time). Small branches can be grabbed by  
the chain and thrown back at you, causing serious  
injury.  
10 Check the chain tension.  
General working instructions  
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.  
4
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.  
Wear personal protective equipment. See instructions  
under the heading Personal protective equipment.

Take great care when cutting a tree that is under  
tension. 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.  
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.  
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.  
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.  
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!  
General rules  
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!  
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.  
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.  
Lack of concentration can lead to kickback if the  
kickback zone of the bar accidentally touches a  
branch, nearby tree or some other object.

Always use a fast cutting speed, i.e. full throttle.  
Basic cutting technique  
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.  
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.  
!
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).  
8
Unless the user resists this pushing force there is a  
risk 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.  
Cutting from above = Cutting with a pulling chain.  
Cutting from below = Cutting with pushing chain.  
Cutting with a pushing chain increases the risk of  
kickback. See instructions under the heading How to  
avoid kickback.  
Terms  
Cutting = General term for cutting through wood.  
Limbing = Cutting branches off a felled tree.  
Splitting = When the object you are cutting breaks off  
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.  
before the cut is complete.  
There are five important factors you should consider  
before making a cut:  
1
Make sure the cutting equipment will not jam in the  
cut.  
2
3
Make sure the object you are cutting will not split.  
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.  
Make sure the chain will not strike the ground or any  
other object during or after cutting.

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.  
safely you can stand and move about?  
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.  
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! 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.  
If it is possible (can you turn the log?) stop cutting about  
2/3 of the way through the log.  
The following instructions describe how to handle the  
common situations you are likely to encounter when using  
a chain saw.  
Limbing  
When limbing thick branches you should use the same  
approach as for cutting.  
Cut difficult branches piece by piece.  
Turn the log and finish the cut from the opposite side.

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.

WORKING TECHNIQUES  
Start by cutting from above (about 1/3 of the way through).  
Finish by cutting from below so that the two cuts meet.  
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.  
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.  
Tree felling technique  
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!  
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.  
IMPORTANT! During critical felling operations, hearing  
protectors should be lifted immediately when sawing is  
completed so that sounds and warning signals can be  
heard.  
Felling direction  
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.  
Clearing the trunk and preparing your retreat  
Once you have decided which way you want the tree to fall  
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.  
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  
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.

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.  
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.

with a diameter larger than the bar length  
of your saw!  
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.  
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.  
Directional cuts  
To make the directional cut you begin with the top cut.Aim  
using to the saw’s felling direction mark (1) toward a goal  
further forward in the terrain, where you would like the tree  
to fall (2). Stand on the right-hand side of the tree, behind  
the saw, and cut with a pull stroke.  
Next make the bottom cut so that it finishes exactly at the

end 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°.

tree should start to fall by itself or with the aid of a felling  
wedge or breaking bar.  
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 safest method is to use a winch.  
Tractor-mounted  
Portable  
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.  
Cutting trees and branches that are in tension  
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).  
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.  
Freeing a tree that has fallen badly  
Freeing a ”trapped tree”  
General advice:  
Position yourself so that you will be clear of the tree or  
branch when the tension is released.  
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.

WORKING TECHNIQUES  
Kickback only occurs if the kickback zone of the bar  
touches an object.  
Continue to cut deeper until tree/limb bends and tension  
is released.  
Limbing  
Cut tree/limb from outside the bend, after tension has  
been released.  
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.

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 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.  
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.  
What is kickback?  
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.  
Keep the trunk between you and the chain saw as you  
move along the trunk.  
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.  
Cutting the trunk into logs

MAINTENANCE  
The L and H-jets are used to adjust the supply of fuel  
General  
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.  
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).  
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.  
Carburetor adjustment  
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.  
Basic settings and running in  
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.  
H
L
CAUTION! If the chain rotates while idling theT-screw  
must be turned anti-clockwise until the chain stops.  
1/2  
1/2  
Rec. idle speed: 2700 rpm  
Fine adjustment  
When the machine has been ”run-in” the 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.  
Your Husqvarna product has been designed and  
manufactured to specifications that reduce harmful  
emissions.  
Conditions  
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.  
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.  
Do not attempt to adjust the L and H jets beyond  
either stop as this could cause damage.  
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.  
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.  
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.  
The carburetor has three adjustment controls:  
Low speed jet L  
- L = Low speed jet  
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.  
- H = High speed jet  
- T = Idle adjustment screw  
H
L
Fine adjustment of the idling speed T  
Adjust the idle speed with the T-screw. If it is necessary to  
re-adjust, turn the T-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.

MAINTENANCE  
Checking, maintaining and  
servicing chain saw safety  
equipment  
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.  
!
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.  
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 necessary to make minor  
adjustments to the high speed jet.  
Chain brake and front hand guard  
Checking brake band wear  
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.  
Brush off any wood dust, resin and dirt from the chain  
brake and clutch drum. Dirt and wear can impair  
operation of the brake.  
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.  
Regularly check that the brake band is at least 0.024 inch  
(0.6 mm) thick at its thinnest point.  
Checking the front hand guard  
Make sure the front hand guard is not damaged and that  
there are no visible defects such as cracks.  
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 inertia brake release  
Throttle lockout  
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.  
Make sure the throttle control is locked at the idle  
setting when the throttle lockout is released.  
Press the throttle lockout and make sure it returns to  
its original position when you release it.  
When the bar hits the stump the brake should be  
applied.  
Check that the throttle control and throttle lockout  
move freely and that the return springs work properly.  
Checking the brake trigger  
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.  
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.  
Chain catcher  
Grasp the chain saw firmly, wrapping your fingers and  
thumbs around the handles.  
Check that the chain catcher is not damaged and is firmly  
attached to the body of the chain saw.  
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.

MAINTENANCE  
Muffler  
Right hand guard  
Check that the right hand guard is not damaged and that  
there are no visible defects, such as cracks.  
Never use a machine that has a faulty muffler.  
Regularly check that the muffler is securely attached to  
the machine.  
Vibration damping system  
Regularly check the vibration damping units for cracks or  
deformation.  
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.  
Make sure the vibration damping units are securely  
attached to the engine unit and handle unit.  
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.  
Stop switch  
Start the engine and make sure the engine stops when  
you move the stop switch to the stop setting.  
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.

MAINTENANCE  
Air filter  
The air filter must be regularly cleaned to remove dust  
and dirt in order to avoid:  
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.  
Carburettor malfunctions  
Starting problems  
Loss of engine power  
Unnecessary wear to engine parts  
Excessive fuel consumption.  
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.  
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.  
Needle bearing lubrication  
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.  
The clutch drum has a needle bearing on the output shaft.  
This needle bearing must be lubricated regularly (once a  
week).  
When lubricating, remove the clutch cover by loosening  
the two bar nuts. Lay the saw on its side with the clutch  
drum upwards.  
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.  
Lubrication involves grease being squirted into the centre  
of the crankshaft using a grease gun.  
Spark plug  
The spark plug condition is influenced by:  
Incorrect carburetor adjustment.  
An incorrect fuel mixture (too much or incorrect type  
of oil).  
A dirty air filter.  
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  
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.  
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.

MAINTENANCE  
Heated handles  
(346XPG, 353G)  
On models with the designation XPG/G, the front as well  
as the rear handle are equipped with electric heating  
coils. These are fed with electrical current from an  
integrated generator in the chain saw.  
When the switch is pushed downwards, the heat is  
switched on. When the switch is pushed upwards, the  
heat is switched off.  
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.  
Electrical carburetor heating  
(346XPG, 353G)  
On models with the designation CARBURETOR  
HEATING there is an electrically heated carburetor.  
Electrically powered heating prevents ice formation in the  
carburetor. A thermostat regulates the heating so that the  
carburetor always has the right working temperature.  
These reduce the flow of cooling air and prevent large  
amounts of snow from being sucked into the carburetor  
space.  
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 346XP and 353. The  
combinations of power head, bar and chain have been tested and found to be 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 hard nose.  
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  
Chain saw models Husqvarna 346XP and 353 met the kickback performance requirements of ANSI B 175.1-2000 when  
tested with the combinations of bars and saw chains listed below.The saw chain Husqvarna H30 is also classified as a  
low kickback saw chain since it met the requirements for low kickback saw chain outlined in ANSI B 175.1-2000. We  
recommend to use only the listed combinations of bars and chains for chain saw models Husqvarna 346XP and 353.  
Other chain saw models may not meet the kickback requirements when equipped with the listed bar and chain  
combinations.

AMERICAN STANDARD SAFETY PRECAUTIONS  
Other safety precautions  
Safety precautions for chain saw  
users  
WARNING! Do not operate a chain saw  
with 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.  
(ANSI B 175.1-2000 Annex C)  
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.  
Do not start cutting until you have a clear work area,  
secure footing and a planned retreat path from the falling  
tree.  
Pinching the saw chain along the top of  
the guide bar may push the guide bar  
rapidly back towards the operator.  
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.  
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.  
With a basic understanding of kickback, you can reduce  
or eliminate the element of surprise. Sudden surprise  
contributes to accidents.  
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.  
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.  
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.  
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.  
Do not operate a chain saw above shoulder height.  
Follow manufacturer’s sharpening and maintenance  
instructions for the saw chain.  
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.)  
Only use replacement bars and chains specified by the  
manufacturer or the equivalent.  
When transporting your chain saw, use the appropriate  
guide bar guard.  
Note:This Annex is intended primarily for the consumer or  
occasional user.
