INTRODUCTION
Dear Customer,
Symbols on the machine:
WARNING! Chain saws can be
dangerous! Careless or incorrect use
can result in serious or fatal injury to
the operator or others.
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 Husqvarna
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 the more
than 300 years of beeing, 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.
Please read the operator’s manual
carefully and make sure you
understand the instructions before
using the machine.
Always wear:

GENERAL SAFETY PRECAUTIONS
Before using a new chain saw
Important
•
•
•
Please read this manual carefully.
IMPORTANT!
(1) - (51) refer to figures on p. 2-5.
The machine is only designed for cutting wood.
Check that the cutting equipment is correctly fitted and
adjusted. See instructions under the heading Assembly.
You should only use the saw with the bar and chain
combinations we recommend in the chapter Technical
data.
•
•
•
Refuel and start the chain saw. See the instructions
under the headings Fuel Handling and Starting and
Stopping.
Never use the machine if you are fatigued, while under
the influence of alcohol or drugs, medication or
anything that could affect your vision, alertness,
coordination or judgement.
Do not use the chain saw until sufficient chain oil has
reached the chain. See instructions under the heading
Lubricating cutting equipment.
Wear personal protective equipment. See instructions
under the heading Personal protective equipment.
Long-term exposure to noise can result in permanent
hearing impairment. So always use approved hearing
protection.
Do not modify this product or use it if it appears to have
been modified by others.
Never use a machine that is faulty. Carry out the
checks, maintenance and service instructions
described in this manual. Some maintenance and
service measures must be carried out by trained and
qualified specialists. See instructions under the
heading Maintenance.
WARNING! Under no circumstances may
the design of the machine be modified
without the permission of the
manufacturer. Always use genuine
accessories. Non-authorized
modifications and/or accessories can
result in serious personal injury or the
death of the operator or others.
!
Never use any accessories other than those
recommended in this manual. See instructions under
the headings Cutting equipment and Technical data.
WARNING! A chain saw is a dangerous
tool if used carelessly or incorrectly and
can cause serious, even fatal injuries. It
is very important that you read and
understand the contents of this
operator’s manual.
CAUTION! Always wear protective glasses or a face
visor to reduce the risk of injury from thrown objects. A
chain saw is capable of throwing objects, such as wood
chips, small pieces of wood, etc, at great force. This
can result in serious injury, especially to the eyes.
!
WARNING! Running an engine in a
confined or badly ventilated area can
result in death due to asphyxiation or
carbon monoxide poisoning.
WARNING! The inside of the muffler
contain chemicals that may be
carcinogenic. Avoid contact with these
elements in the event of a damaged
muffler.
!
!
WARNING! Faulty cutting equipment or
the wrong combination of bar and saw
chain increases the risk of kickback!
!
WARNING! Long term inhalation of the
engine’s exhaust fumes, chain oil mist
and dust from sawdust can represent a
health risk.
Only use the bar/saw chain
combinations we recommend, and
follow the filing instructions. See
instructions under the headingTechnical
data.
!
WARNING! This machine produces an
electromagnetic field during operation.

circumstances interfere with active or
passive medical implants.To reduce the
risk of serious or fatal injury, we
recommend persons with medical
implants to consult their physician and
the medical implant manufacturer before
operating this machine.
It is not possible to cover every conceivable situation you
can face when using a chain saw. Always exercise care
and use your common sense. Avoid all situations which
you consider to be beyond your capability. If you still feel
uncertain about operating procedures after reading these
instructions, you should consult an expert before
continuing. Do not hesitate to contact your dealer or us if
you have any questions about the use of the chain saw.We
will willingly be of service and provide you with advice as
well as help you to use your chain saw both efficiently and
safely. Attend a training course in chain saw usage if
possible.Your dealer, forestry school or your library can
provide information about which training materials and
courses are available. Work is constantly in progress to
improve the design and technology - improvements that

GENERAL SAFETY PRECAUTIONS
increase your safety and efficiency. Visit your dealer
brake reduces the risk of accidents, but only you can
regularly to see whether you can benefit from new features
that have been introduced.
prevent them.
Take care when using your saw and make sure the
kickback zone of the bar never touches any object (45).
Personal protective equipment
•
•
•
•
The chain brake (A) can either be activated manually
(by your left hand) or automatically by the inertia release
mechanism.(3)
The brake is applied when the front hand guard (B) is
pushed forwards or when the right-hand brake trigger
(E) is pushed up and forwards (240e TrioBrake). (3)
This movement activates a spring-loaded mechanism
that tightens the brake band (C) around the engine drive
system (D) (clutch drum). (4)
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.
WARNING! Most chain saw accidents
happen when the chain touches the
operator.You must use approved
personal protective equipment whenever
you use the machine. Personal
!
protective equipment cannot eliminate
the risk of injury but it will reduce the
degree of injury if an accident does
happen. Ask your dealer for help in
choosing the right equipment.
•
•
•
•
•
•
Approved protective helmet
Hearing protection
•
•
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.
Protective goggles or a visor
Gloves with saw protection
Trousers with saw protection
•
•
To release the chain brake pull the front hand guard
backwards, towards the front handle.
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.
Boots with saw protection, steel toe-cap and non-slip
sole
•
•
Always have a first aid kit nearby.
Fire Extinguisher and Shovel
Generally clothes should be close-fitting without restricting
your freedom of movement.
•
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.
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.
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.
Machine′s safety equipment
If the kickback is less violent or the kickback zone of the
bar is closer to you the chain brake will 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.
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 service workshop.
Will my hand always activate the chain
brake during a kickback?
WARNING! Never use a machine with
defective safety components. Safety
equipment must be inspected and
maintained. See instructions under the
heading Checking, maintaining and
servicing chain saw safety equipment. If
your machine does not pass all the
checks, take the saw to a servicing
dealer for repair.
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 brake and front hand guard
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.
Your chain saw is equipped with a chain brake that is
designed to stop the chain if you get a kickback.The chain

GENERAL SAFETY PRECAUTIONS
with cutting equipment that is blunt or faulty (wrong type or
badly sharpened) will increase the vibration level.
Will my inertia activated chain brake
always activate during kickback in the
event of a kickback?
WARNING! Overexposure to vibration
can lead to circulatory damage or nerve
damage in people who have impaired
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.
!
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.
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.
Stop switch
Use the stop switch to switch off the engine.
Muffler
The muffler is designed to reduce noise levels and to direct
exhaust fumes away from the user.
Only you and proper working technique can eliminate
kickback and its danger.
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!
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. (5)
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 mesh (A). (6)
Chain catcher
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.
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).
WARNING! Never use a saw without a
muffler, or with a damaged muffler. A
damaged muffler may substantially
!
Right hand guard
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.
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.
Vibration damping system
Your machine is equipped with a vibration damping system
that is designed to minimize vibration and make operation
easier.
Cutting equipment
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
chain saw, including the cutting equipment, is insulated
from the handles by vibration damping units.
This section describes how to choose and maintain your
cutting equipment in order to:

links of the chain must match the spacing of the teeth on
the bar tip sprocket and drive sprocket. 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.
Bar groove width (inches/mm). The groove in the bar
must match the width of the chain drive links.
Chain oil hole and hole for chain tensioner.The bar must
be matched to the chain saw design.
•
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.
•
•
•
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.

Sharpening your chain and adjusting
depth gauge setting
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.
WARNING! Always wear gloves, when
working with the chain, in order to
protect your hands from injury.

Cutting equipment designed to reduce
kickback
General information on sharpening cutting teeth
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 headingTechnical
data.
•
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.
!
•
•
A sharp chain eats its way through the wood and
produces long, thick chips or shavings.
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). (7)
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.
When you sharpen a cutting tooth there are four important
factors to remember.

Filing angle
Cutting angle
File position
Bar
The smaller the tip radius the lower the chance of kickback.
Round file diameter
Chain
It is very difficult to sharpen a chain correctly without the
right equipment. We recommend that you use our file
gauge. This will help you obtain the maximum kickback
reduction and cutting performance from your chain.
See instructions under the heading Technical data for
information about sharpening your 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.
WARNING! Departure from the
sharpening instructions considerably
increases the risk of kickback.
WARNING! Any contact with a rotating
saw chain can cause extremely serious
injuries.
!
!
Sharpening cutting teeth
Some terms that describe the bar and chain
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.
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.
•
Check that the chain is correctly tensioned. A slack
chain will move sideways, making it more difficult to
sharpen correctly.

tension. Lift tip of guide bar while adjusting tension. (12)
•
File all the teeth to the same length. When the length of
the cutting teeth is reduced to 4 mm (0.16") the chain is
worn out and should be replaced. (8)
•
•
Tighten the clutch cover by turning the knob clockwise
while lifting tip of bar. (13)
Fold the knob back in to lock the tensioning. (14)
General advice on adjusting depth gauge setting (7)
•
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.
Lubricating cutting equipment
WARNING! Poor lubrication of cutting
equipment may cause the chain to snap,
which could lead to serious, even fatal
injuries.
!
WARNING! The risk of kickback is
increased if the depth gauge setting is
Chain oil
!
too large!
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.
Adjustment of depth gauge setting
As a chain saw manufacturer we have developed an
optimal chain oil which, with its vegetable oil base, is also
biodegradable. 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.
•
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.
Never use waste oil! Using waste oil can be dangerous
to you and damage the machine and environment.
•
•
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.
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.
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.
Filling with chain oil
•
All our chain saws have an automatic chain lubrication
system. On some models the oil flow is also adjustable.
Tensioning the chain
•
The saw chain oil tank and the fuel tank are designed so
that the fuel runs out before the saw chain oil.
WARNING! A slack chain may jump off
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).
and cause serious or even fatal injury.
!
!
WARNING! Always wear approved
protective gloves. Even a non-moving
chain can cause serious cuts to yourself
or persons you bump into with an
exposed chain.
Checking chain lubrication
•
Check the chain lubrication each time you refuel. See
instructions under the heading Lubricating the bar tip
sprocket.
The more you use a chain the longer it becomes. It is
therefore important to adjust the chain regularly to take up
the slack.
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.
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.
If the chain lubrication is not working:
Tension the chain as tightly as possible, but not so tight that
you cannot pull it round freely by hand. (9)
•
Check that the oil channel in the bar is not obstructed.
Clean if necessary.
•
•
Release the knob by folding it out. (10)
•
Check that the groove in the edge of the bar is clean.
Clean if necessary.
Turn the knob anti clockwise to loosen the bar cover.

carrying out any checks or maintenance.
The stop switch automatically returns to
the start position. In order to prevent
unintentional starting, the spark plug
cap must be removed from the spark
plug when assembling, checking and/or
performing maintenance.
!
Chain drive sprocket
The clutch drum is fitted with a Spur sprocket (the chain
sprocket is welded on the drum).
Regularly check the degree of wear on the drive sprocket.
Replace if wear is excessive. Replace the drive sprocket
whenever you replace the chain.
Always wear gloves, when working with
the chain, in order to protect your hands
from injury.
Checking wear on cutting equipment
Check that the chain brake is in disengaged position by
moving the front hand guard towards the front handle.
Check the chain daily for:
•
•
•
Visible cracks in rivets and links.
Whether the chain is stiff.
Whether rivets and links are badly worn.
Remove the knob and remove the clutch cover (chain
brake). Take off the transportation ring (A). (17)
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.
(18)
Replace the saw chain if it exhibits any of the points above.
We recommend you compare the existing chain with a new
chain to decide how badly the existing chain is worn.
When the length of the cutting teeth has worn down to only
4 mm the chain must be replaced.
Make sure that the edges of the cutting links are facing
forward on the top edge of the bar.
Bar
Fit the clutch cover (chain brake) and locate the chain
adjuster pin in the cut-out in the bar. Check that the drive
links of the chain fit correctly on the drive sprocket and that
the chain is in the groove on the bar. (19)
Check regularly:
•
•
•
Whether there are burrs on the edges of the bar.
Remove these with a file if necessary. (15)
Tension the chain by turning the wheel down (+).The chain
should be tensioned until it does not sag from the
underside of the bar. (12)
Whether the groove in the bar has become badly worn.
Replace the bar if necessary. (16)
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.
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 knob by
turning the knob clockwise. (13)
•
To prolong the life of the bar you should turn it over daily.
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. (20)
WARNING! Most chain saw accidents
happen when the chain touches the
operator.

FUEL HANDLING
Chain oil
Fuel
•
•
•
•
We recommend the use of special oil (chain oil) with
Note! The machine is equipped with a two-stroke engine
and must always be run using a mixture of petrol 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.
good adhesion characteristics.
Never use waste oil. This results in damage to the oil
pump, the bar and the chain.
It is important to use oil of the right grade (suitable
viscosity range) to suit the air temperature.
In temperatures below 0°C (32°F) some oils become too
viscous. This can overload the oil pump and result in
damage to the oil pump components.
WARNING! Always ensure there is
adequate ventilation when handling fuel.
!
•
Contact your service agent when choosing chain oil.
Fuelling
Petrol
WARNING! Taking the following
precautions, will lessen the risk of fire:
•
•
Use good quality unleaded or leaded petrol.
The lowest recommended octane grade is 90 (RON). If
you run the engine on a lower octane grade than 90 so-
called knocking can occur. This gives rise to a high
engine temperature and increased bearing load, which
can result in serious engine damage.
!
Do not smoke and do not place any hot
objects in the vicinity of fuel.
Always stop the engine and let it cool for
a few minutes before refuelling.
•
When working with continuous high revs (e.g. limbing) a
higher octane is recommended.
When refuelling, open the fuel cap
slowly so that any excess pressure is
released gently.
Running-in
Avoid running at a too high speed for extended periods
during the first 10 hours.
Tighten the fuel cap carefully after
refuelling.
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.
Always move the machine away from the
refuelling area before starting.
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.
•
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.
A poor oil quality and/or too high oil/fuel ratio may
jeopardise function and decrease the life time of
catalytic converters.

starter pawls engage) then pull firmly and rapidly. Never
twist the starter cord around your hand. (26)
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.
4. Push in the choke control to the ”1/2 choke” setting as
soon as the engine fires which can be heard through a
"puff" sound. (22)
5. Keep on pulling the cord powerfully until the engine

squeeze throttle trigger to set normal idle.
As the chain brake is still engaged the speed of the engine
must be set to idling as soon as possible, this is achieved by
quickly pressing the throttle trigger once. This prevents
unnecessary wear to the clutch, clutch drum and brake band.
•
•
•
•
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.
Note! Reactivate the chain brake by pushing the front hand
guard back (marked ”PULL BACK TO RESET”) towards
the front handle. (28) The chain saw is now ready for use.
There is a simplified start reminder with illustrations to
describe each step on the rear edge of the saw (A).

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.
WARNING! Long term inhalation of the
engine’s exhaust fumes, chain oil mist
and dust from sawdust can represent a
health risk.

serious injury. (29)
The chain brake should be activated when starting. See
instructions under the heading Start and stop. Do not
drop start.This method is very dangerous because you
may lose control of the saw. (30)
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.
Keep people and animals well away from
the working area.

General working instructions
IMPORTANT!
General rules
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 feel unsure of!
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 minimises the effect of kickback
and lets you keep the chain saw under control. Do not
let go of the handles!
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.
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.
Wear personal protective equipment. See instructions
under the heading Personal protective equipment.
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.This is not necessarily
dangerous in itself, but 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.
Never use the chain saw above shoulder height and
try not to cut with the tip of the bar. Never use the
chain saw one-handed! (34)
You must have a steady stance in order to have full
control over the chain saw. Never work standing on a
ladder, in a tree or where you do not have firm ground to
stand on. (35)
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 on the push stroke. 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.
Basic safety rules
1
Look around you:
•
To ensure that people, animals or other things cannot
affect your control of the machine.
•
To make sure that none of the above might come within
reach of your saw or be injured by falling trees.
CAUTION! Follow the instructions above, but do not use a
chain saw in a situation where you cannot call for help in
case of an accident.

2
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.
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.

Unless the user resists this pushing force there is a risk
The following instructions describe how to handle the
commonest situations you are likely to encounter when
using a chain saw.
that the chain saw will move so far backwards that only
the kickback zone of the bar is in contact with the tree,
which will lead to a kickback. (36)
Limbing
Cutting with the bottom edge of the bar, i.e. from the top
of the object downwards, is known as cutting on the pull
stroke. 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 on the pull
stroke gives the operator better control over the chain
saw and the position of the kickback zone.
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.
When limbing thick branches you should use the same
approach as for cutting.
Cut difficult branches piece by piece.
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.
9
!
Basic cutting technique
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.
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.
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 lying on the ground. There is little risk of the
chain jamming or the object splitting. However there is a
risk that the chain will touch the ground when you finish the
cut.
Cut all the way through the log from above.Avoid letting the
chain touch the ground as you finish the cut. Maintain full
throttle but be prepared for what might happen. (37)
If it is possible (can you turn the log?) stop cutting about 2/
3 of the way through the log.
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 on the pull stroke.
Cutting from below = Cutting on the push stroke.
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 on the push stroke increases the risk of kickback.
See instructions under the heading How to avoid kickback.
Terms
Start by cutting from below (about 1/3 of the way through).
Finish by cutting from above so that the two cuts meet.

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:
Tree felling technique
1
2
3
Make sure the cutting equipment will not jam in the cut.
Make sure the object you are cutting will not split.
Make sure the chain will not strike the ground or any
other object during or after cutting.
Is there a risk of kickback?
Do the conditions and surrounding terrain affect how
safely you can stand and move about?
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 that you feel unsure of!
4
5
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. (38)
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.
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! 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.
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:

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.
Make the felling cut about 3-5 cm (1.5-2 inches) above the
bottom directional cut.
Set the spike bumper (if one is fitted) just behind the felling
hinge. Use full throttle and advance the chain/bar slowly
into the tree. Make sure the tree does not start to move in
the opposite direction to your intended felling direction.
Drive a wedge or breaking bar into the cut as soon as it is
deep enough. (42)
•
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.
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.
The felling hinge controls the direction that the tree falls in.
(43)
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.
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.
IMPORTANT! During critical felling operations, hearing
protectors should be lifted immediately when sawing is
completed so that sounds and warning signals can be
heard.
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.
Clearing the trunk and preparing your retreat
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.
Remove any undergrowth from the base of the tree and
check the area for obstacles (stones, branches, holes, etc.)
so that you have a clear path of retreat when the tree starts
to fall.Your path of retreat should be roughly 135 degrees
away from the intended felling direction. (39)
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.

WARNING! Unless you have special
training we advise you not to fell trees

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.
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).
Directional cuts
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.
To make the directional cuts you begin with the top cut.
Stand to the right of the tree and cut on the pull stroke.
Next make the bottom cut so that it finishes exactly at the
end of the top cut. (40)
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°.
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. (41)
Felling cut
General advice:
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!
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.

Function
•
The carburettor governs the engine’s speed via the
throttle control. Air and fuel are mixed in the carburettor.
The air/fuel mixture is adjustable. Correct adjustment is
essential to get the best performance from the machine.
How to avoid kickback
WARNING! Kickback can happen very
suddenly and violently; kicking the chain
saw, bar and chain back at the user. If

•
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.
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.
Basic settings and running in
The basic carburettor settings are adjusted during testing
at the factory. Fine adjustment should be carried out by a
skilled technician.
What is kickback?
Rec. idle speed: See the Technical data section.
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. (44)
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.
Fine adjustment of the idle 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 anti-
clockwise until the chain stops. When the idle speed is
correctly adjusted the engine should run smoothly in every
position and the engine speed should be safely below the
speed at which the chain starts to rotate.
WARNING! Contact your servicing
Kickback only occurs if the kickback zone of the bar
touches an object. (45)
dealer, if the idle speed setting cannot be
adjusted so that the chain stops. Do not
use the chain saw until it has been
properly adjusted or repaired.
!
Limbing
WARNING! A majority of kickback
accidents occur during limbing. Do not
use the kickback zone of the guide bar.
Checking, maintaining and
servicing chain saw safety
equipment
!
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.
Note! All service and repair work on the machine
demands special training. This is especially true of the
machine’s safety equipment. If your machine fails any
of the checks described below we recommend that you
take it to your service workshop. Any maintenance
other than that described in this manual must be
carried out by your servicing dealer (retailer).
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.
Switch off the engine and take off the ignition cable
before repairs or maintenance
Keep the trunk between you and the chain saw as you
move along the trunk.
Chain brake and front hand guard
Cutting the trunk into logs
Checking brake band wear
See instructions under the heading Basic cutting
technique.
Brush off any wood dust, resin and dirt from the chain
brake and clutch drum. Dirt and wear can impair operation
of the brake. (46)
General
Regularly check that the brake band is at least 0.6 mm
thick at its thinnest point.
The user must only carry out the maintenance and service
work described in this Operator’s Manual. More extensive
work must be carried out by an authorised service
workshop.
Checking the front hand guard
Make sure the front hand guard is not damaged and that
there are no visible defects such as cracks.

MAINTENANCE
Move the front hand guard forwards and back to make sure
it moves freely and that it is securely anchored to the clutch
cover. (47)
Note: The spark arrestor screen (A) on this machine is
serviceable. (50) The mesh must be replaced if it is
damaged. If the mesh 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
mesh is missing or defective.
For normal homeowner use, the muffler and spark
arresting screen will not require replacement. After 75
hours of use, we recommend that your muffler be replaced
by your authorized Husqvarna service dealer.
Checking the inertia brake release
Place the chain saw, with the engine switched off, on a
stump or other stable surface. Release the front handle
and let the saw fall by its own weight, rotating around the
rear handle towards the stump.
When the bar hits the stump the brake should be
applied. (48)
Air filter
Checking the right-hand brake trigger (240eTrioBrake)
The air filter must be regularly cleaned to remove dust and
dirt in order to avoid:
Check that the right hand guard is not damaged and that
there are no visible defects, such as cracks.
•
•
•
•
•
•
Carburettor malfunctions
Starting problems
Loss of engine power
Unnecessary wear to engine parts.
Excessive fuel consumption.
Remove the air filter (3) after taking off the cylinder
cover, screw (1) and filter cover (2).When refitting make
sure that the air filter seals tightly against the filter
holder. Clean the filter by brushing or shaking it. (51)
Push the trigger up and forwards to check that it moves
freely and is securely hinged to the clutch cover.
Never carry or hang the saw by the trigger!This could
damage the mechanism and disable the chain brake.
(49)
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.
Grasp the chain saw firmly, wrapping your fingers and
thumbs around the handles.
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.
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 filter according to working conditions, weather,
season, etc. Contact your dealer for advice.
Throttle lockout
•
•
•
•
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.
Check that the throttle control and throttle lockout move
freely and that the return springs work properly.
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
carburettor idle adjustment.
Spark plug
The spark plug condition is influenced by:
•
•
•
Incorrect carburettor 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 0.5 mm. The
spark plug should be replaced after about a month in
operation or earlier if necessary. (52)
Chain catcher
Check that the chain catcher is not damaged and is firmly
attached to the body of the chain saw.
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.
Right hand guard
Check that the right hand guard is not damaged and that
there are no visible defects, such as cracks.
Vibration damping system
Regularly check the vibration damping units for cracks or
deformation.
Make sure the vibration damping units are securely
attached to the engine unit and handle unit.
Stop switch
Start the engine and make sure the engine stops when you
move the stop switch to the stop setting.
Muffler
Never use a machine that has a faulty muffler. Regularly
check that the muffler is securely attached to the machine.
