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
operator′s manual as a valuable document. By following its′ content (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 operator′s 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.

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

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.

backwards, towards the front handle.
This movement activates a spring-loaded mechanism
that tightens the brake band (C) around the engine
drive system (D) (clutch drum).
•
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 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.
•
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.
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

activated by the inertia action.
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.
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 machine′s vibration damping system reduces the
transfer of vibration between the engine unit/cutting
equipment and the machine′s handle unit.The body of the

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

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.

information about sharpening your chain.
WARNING! Departure from the

increases the risk of kickback.
Sharpening cutting teeth
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.
•
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).
•
•
Check that the chain is correctly tensioned. A slack
chain will move sideways, making it more difficult to
sharpen correctly.
When you sharpen a cutting tooth there are four important
factors to remember.
1
Filing angle
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.

tool.
Tensioning the chain
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.
WARNING! A slack chain may jump off
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.
WARNING! The risk of kickback is
Tension the chain as tightly as possible, but not so tight

!
too large!
Adjustment of depth gauge setting
•
•
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.
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.
•
•
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.
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.
•
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
•
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

surface.
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
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.
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.
If the chain lubrication is not working:
•
Check that the oil channel in the bar is not obstructed.
Clean if necessary.
Never use waste oil! Using waste oil can be dangerous
to you and damage the machine and environment.
•
•
Check that the groove in the edge of the bar is clean.
Clean if necessary.
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.
Filling with chain oil
•
All our chain saws have an automatic chain lubrication
system. On some models the oil flow is also
adjustable.
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.
•
The saw chain oil tank and the fuel tank are designed
so that the fuel runs out before the saw chain oil.
If the chain lubrication system is still not working after
carrying out the above checks and associated measures
you should contact your servicing dealer.
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).
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

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.
!
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
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.

•
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.
Running-in
Do not mix more than one month’s supply of fuel at a
time.
Avoid running at a too high speed for extended periods
during the first 10 hours.
If the machine is not used for some time the fuel tank
Two-stroke oil
should be emptied and cleaned.
•
•
•
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).
Chain oil
•
We recommend the use of special oil (chain oil) with
good adhesion characteristics.
Never use oil intended for four-stroke engines.

Always move the machine away from the
refuelling area before starting.
Transport and storage
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.
•
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 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.
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.
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.
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.
Starting
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.
If the machine is fitted with a decompression valve (A):
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
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.

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.
5
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.
Wear personal protective equipment. See instructions
under the heading Personal protective equipment.
Basic safety rules

•
Look around you:
To ensure that people, animals or other things cannot
affect your control of the machine.

WORKING TECHNIQUES
Lack of concentration can lead to kickback if the
kickback zone of the bar accidentally touches a
branch, nearby tree or some other object.
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.
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
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!
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!
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.

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).
•
•
Cutting from above = Cutting with a pulling chain.
Cutting from below = Cutting with pushing chain.
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.
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
before the cut is complete.
There are five important factors you should consider
before making a cut:

cut.
2
3
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.
Make sure the chain will not strike the ground or any
other object during or after cutting.

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

Two factors decide whether the chain will jam or the object
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.
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.
The following instructions describe how to handle the
common situations you are likely to encounter when using
a chain saw.
If it is possible (can you turn the log?) stop cutting about
2/3 of the way through the log.
Limbing
When limbing thick branches you should use the same
approach as for cutting.
Cut difficult branches piece by piece.

that it will split.
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).
•
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.
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.
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.
IMPORTANT! During critical felling operations, hearing
protectors should be lifted immediately when sawing is
completed so that sounds and warning signals can be
heard.
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:
Clearing the trunk and preparing your retreat

Felling cut
!
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.
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.
Make the felling cut about 1.5-2 inches (3-5 cm) above the
bottom directional cut.
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.
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.
Next make the bottom cut so that it finishes exactly at the
end of the top cut.
The felling hinge controls the direction that the tree falls in.

hinge is too narrow or non-existent, or if the directional
cuts and felling cut are badly placed.
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.
Never work in the risk zone of the hanging trapped tree.
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).
Freeing a tree that has fallen badly
Freeing a ”trapped tree”
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.
It is very dangerous to remove a trapped tree and there is
high accident risk.

WORKING TECHNIQUES
General advice:
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.
Position yourself so that you will be clear of the tree or
branch when the tension is released.
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!
Kickback only occurs if the kickback zone of the bar
touches an object.
If you must cut across tree/limb, make two to three cuts,
one inch apart, one to two inches deep.
Continue to cut deeper until tree/limb bends and tension
is released.
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.
Cut tree/limb from outside the bend, after tension has
been released.
How to avoid kickback
WARNING! Kickback can happen very
suddenly and violently; kicking the chain

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.
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.

possibilities to a maximum of a 1/2 turn.
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.
CAUTION! If the chain rotates while idling theT-screw
must be turned anti-clockwise until the chain stops.

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.
Conditions
Your Husqvarna product has been designed and
manufactured to specifications that reduce harmful
emissions.
•
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.
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 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.
The carburetor has three adjustment controls:
- L = Low speed jet
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.
- H = High speed jet
- T = Idle adjustment screw
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.

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.

Checking the front hand guard
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.
Make sure the front hand guard is not damaged and that
there are no visible defects such as cracks.
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.
Move the front hand guard forwards and back to make
sure it moves freely and that it is securely anchored to the
clutch cover.
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.
Checking the inertia brake release
Checking, maintaining and
servicing chain saw safety
equipment
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.
Note! All servicing and repair work on the machine
requires special training. This is especially true of the
machine′s safety equipment. If your machine fails any
of the checks described below we recommend you to
contact our servicing dealer.
Chain brake and front hand guard
Checking brake band wear
When the bar hits the stump the brake should be
applied.
Brush off any wood dust, resin and dirt from the chain
brake and clutch drum. Dirt and wear can impair
operation of the brake.
Regularly check that the brake band is at least 0.024 inch
(0.6 mm) thick at its thinnest point.

Checking the brake trigger
•
•
•
Press the throttle lockout and make sure it returns to
its original position when you release it.
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 throttle control and throttle lockout
move freely and that the return springs work properly.
Grasp the chain saw firmly, wrapping your fingers and
thumbs around the handles.
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
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 chain catcher is not damaged and is firmly
attached to the body of the chain saw.
Throttle lockout
•
Make sure the throttle control is locked at the idle
setting when the throttle lockout is released.
Right hand guard
Check that the right hand guard is not damaged and that
there are no visible defects, such as cracks.

MAINTENANCE
Regularly check that the muffler is securely attached to
Vibration damping system
the machine.
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.
Muffler
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.
Never use a machine that has a faulty muffler.

Fitting the starter
Spark plug
•
To fit the starter, first pull out the starter cord and place
the starter in position against the crankcase. Then
slowly release the starter cord so that the pulley
engages with the pawls.
The spark plug condition is influenced by:
•
Fit and tighten the screws that hold the starter.
•
•
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.
Air filter
The air filter must be regularly cleaned to remove dust
and dirt in order to avoid:
•
•
•
•
•
•
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.
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.
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.
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.

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.
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
The cooling system consists of:

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.
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.

Winter use
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.
Running problems can occur when using the machine in
the cold and snowy conditions caused by:
•
•
Too low engine temperature.
Icing of the air filter and carburetor.
Special measures are therefore often required:
Heated handles
•
Partly mask the air inlet on the starter to increase the
(357 XPG, 359 G)
working temperature of the engine.
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.
•
Preheat the intake air to the carburetor by using the
heat from the cylinder.
°
°
Temperature 0 C (32 F) or colder:
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.
Electrical carburetor heating
(357 XPG, 359 G)
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.
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.
CAUTION! When the winter plug is fitted the winter flap
must be open!

Recommended original and replacement bar and chain combinations
Following is a list of recommended cutting equipment for the Husqvarna chain saw models 357XP and 359. 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 357XP and 359 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 357XP and 359.
Other chain saw models may not meet the kickback requirements when equipped with the listed bar and chain
combinations.

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
Tip contact in some cases may cause a
lightning fast reverse reaction, kicking
the guide bar up and back towards the
operator.
gloves, and eye, hearing and head protection devices.
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
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.
the engine is running.
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.
