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

GENERAL SAFETY PRECAUTIONS  
Before using a new chain saw  
Important  
Please read this manual carefully.  
IMPORTANT!  
Check that the cutting equipment is correctly fitted and  
adjusted. See instructions under the heading Assembly.  
The machine is only designed for cutting wood.  
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.  
Long-term exposure to noise can result in permanent  
hearing impairment. So always use approved hearing  
protection.  
Wear personal protective equipment. See instructions  
under the heading Personal protective equipment.  
Do not modify this product or use it if it appears to have  
been modified by others.  
WARNING! Under no circumstances may  
the design of the machine be modified  
!
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.  
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.  
Your warranty may not cover damage or  
liability caused by the use of non-  
authorized accessories or replacement  
parts.  
Never use any accessories other than those  
recommended in this manual. See instructions under the  
headings Cutting equipment and Technical data.  
CAUTION! Always wear protective glasses or a face visor  
to reduce the risk of injury from thrown objects. A chain  
saw is capable of throwing objects, such as wood chips,  
small pieces of wood, etc, at great force.This can result in  
serious injury, especially to the eyes.  
WARNING! A chain saw is a dangerous tool  
if used carelessly or incorrectly and can  
cause serious, even fatal injuries. It is very  
important that you read and understand the  
contents of this operator’s manual.  
!
WARNING! Running an engine in a confined  
or badly ventilated area can result in death  
due to asphyxiation or carbon monoxide  
poisoning.  
!
WARNING!The inside of the muffler contain  
chemicals that may be carcinogenic. Avoid  
contact with these elements in the event of  
a damaged muffler.  
!
WARNING! Faulty cutting equipment or the  
wrong combination of bar and saw chain  
!
increases the risk of kickback! Only use the  
bar/saw chain combinations we  
recommend, and follow the filing  
instructions. See instructions under the  
heading Technical data.  
WARNING! Long term inhalation of the  
engine’s exhaust fumes, chain oil mist and  
dust from sawdust can represent a health  
risk.  
!
WARNING! The ignition system of this  
machine produces an electromagnetic field  
Always use common sense  
!
during operation.This field may under  
some circumstances interfere with  
pacemakers.To reduce the risk of serious  
or fatal injury, we recommend persons with  
pacemakers to consult their physician and  
the pacemaker manufacturer before  
operating this machine.  
It is not possible to cover every conceivable situation you can  
face when using a chain saw. Always exercise care and use  
your common sense. Avoid all situations which you consider  
to be beyond your capability. If you still feel uncertain about  
operating procedures after reading these instructions, you  
should consult an expert before continuing. Do not hesitate  
to contact your dealer or us if you have any questions about  
the use of the chain saw. We will willingly be of service and  
provide you with advice as well as help you to use your chain  
saw both efficiently and safely. Attend a training course in  
chain saw usage if possible.Your dealer, forestry school or

tools available if you should need them.Help prevent forest  
fires.  
Machine s safety equipment  
In this section the machine’s safety features and their  
function are explained. For inspection and maintenance see  
instructions under the heading Checking, maintaining and  
servicing chain saw safety equipment. See instructions  
under the heading, What is what?, to find where these parts  
are located on your machine.  
Work is constantly in progress to improve the design and  
technology - improvements that increase your safety and  
efficiency.Visit your dealer regularly to see whether you can  
benefit from new features that have been introduced.  
The life span of the machine can be reduced and the risk of  
accidents can increase if machine maintenance is not  
carried out correctly and if service and/or repairs are not  
carried out professionally. If you need further information  
please contact your nearest servicing dealer.  
Personal protective equipment  
WARNING! Most chain saw accidents  
happen when the chain touches the  
WARNING! Never use a machine with  
defective safety components. Safety  
equipment must be inspected and  
maintained. See instructions under the  
heading Checking, maintaining and

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.  
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.  
Approved protective helmet  
Hearing protection  
Protective goggles or a visor  
Gloves with saw protection  
Trousers with saw protection

The chain brake (A) can either be activated manually (by  
your left hand) or automatically by the inertia release  
mechanism.  
Always have a first aid kit nearby.

GENERAL SAFETY PRECAUTIONS  
This movement activates a spring-loaded mechanism  
Kickback can be very sudden and violent. Most  
that tightens the brake band (C) around the engine drive  
system (D) (clutch drum).  
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 way the chain brake is activated, either manually or  
automatically by the inertia release mechanism,  
depends on the force of the kickback and the position of  
the chain saw in relation to the object that the kickback  
zone of the bar strikes.  
The front hand guard is not designed solely to activate  
the chain brake. Another important feature is that it  
reduces the risk of your left hand hitting the chain if you  
lose grip of the front handle.  
If you get a violent kickback while the kickback zone of  
the bar is farthest away from you the chain brake is  
designed to be activated by the inertia in the kickback  
direction.  
The chain brake must be engaged when the chain saw is  
started to prevent the saw chain from rotating.  
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.  
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.  
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.  
To release the chain brake pull the front hand guard  
backwards, towards the front handle.

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

GENERAL SAFETY PRECAUTIONS  
cutting equipment that is blunt or faulty (wrong type or badly  
sharpened) will increase the vibration level.  
requiring among other things the muffler must be equipped  
with an approved type of spark arrestor screen.  
WARNING! Overexposure to vibration can  
lead to circulatory damage or nerve  
damage in people who have impaired  
circulation. Contact your doctor if you  
experience symptoms of overexposure to  
vibration. Such symptoms include  
numbness, loss of feeling, tingling,  
pricking, pain, loss of strength, changes in  
skin colour or condition.These symptoms  
normally appear in the fingers, hands or  
wrists.These symptoms may be increased  
in cold temperatures.  
CAUTION! The muffler gets very hot during and after use.  
This also applies during idling. Be aware of the fire hazard,  
especially when working near flammable substances and/  
or vapours.  
!
WARNING! Never use a saw without a  
muffler, or with a damaged muffler. A  
!
damaged muffler may substantially  
increase the noise level and the fire hazard.  
Keep fire fighting equipment handy. If a  
spark arrestor screen is required in your  
area, never use the saw without or with a  
broken spark arrestor screen.  
Stop switch  
Use the stop switch to switch off the engine.  
Cutting equipment  
This section describes how to choose and maintain your  
cutting equipment in order to:  
Reduce the risk of kickback.  
Reduce the risk of the saw chain breaking or jumping off  
the bar.  
Obtain optimal cutting performance.  
Extend the life of cutting equipment.  
Avoid increasing vibration levels.  
Muffler  
General rules  
The muffler is designed to keep noise levels to a minimum  
and to direct exhaust fumes away from the user.  
Only use cutting equipment recommended by us!  
See instructions under the heading Technical data.  
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!  
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.  
In areas with a hot, dry climate there is a high risk of fires.  
These areas are sometimes subject to government rules  
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.

increases the risk of kickback! Only use the  
bar/saw chain combinations we  
recommend, and follow the filing  
instructions. See instructions under the  
heading Technical data.  
Bar groove width (inches/mm). The groove in the bar  
must match the width of the chain drive links.  
The only way to avoid kickback is to make sure that the  
kickback zone of the bar never touches anything.  
By using cutting equipment with ”built-in” kickback reduction  
and keeping the chain sharp and well-maintained you can  
reduce the effects of kickback.

GENERAL SAFETY PRECAUTIONS  
will help you obtain the maximum kickback reduction and  
cutting performance from your chain.  
Sharpening your chain and adjusting depth  
gauge setting  
General information on sharpening cutting teeth  
Never use a blunt chain. When the chain is blunt you  
have to exert more pressure to force the bar through the  
wood and the chips will be very small. If the chain is very  
blunt it will produce wood powder and no chips or  
shavings.  
A sharp chain eats its way through the wood and  
produces long, thick chips or shavings.  
See instructions under the heading Technical data for  
information about sharpening your chain.  
WARNING! Departure from the sharpening  
instructions considerably increases the  
risk of kickback.  
!
Sharpening cutting teeth  
The cutting part of the chain is called the cutter and  
consists of a cutting tooth (A) and the depth gauge (B).  
The cutters cutting depth is determined by the difference  
in height between the two (depth gauge setting).  
To sharpen cutting teeth you will need a round file and a file  
gauge.See instructions under the headingTechnical data for  
information on the size of file and gauge that are  
recommended for the chain fitted to your chain saw.  
When you sharpen a cutting tooth there are four important  
factors to remember.  
Check that the chain is correctly tensioned.A slack chain  
will move sideways, making it more difficult to sharpen  
correctly.  
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.  
2
Cutting angle  
3
4
File position  
File all the teeth to the same length. When the length of  
the cutting teeth is reduced to 0.16 inch (4 mm) the chain  
is worn out and should be replaced.  
Round file diameter  
It is very difficult to sharpen a chain correctly without the right  
equipment.We recommend that you use our file gauge.This  
English 13

GENERAL SAFETY PRECAUTIONS  
General advice on adjusting depth gauge setting  
Tensioning the chain  
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 increased  
if the depth gauge setting is too large!  
!
Tension the chain as tightly as possible, but not so tight that  
you cannot pull it round freely by hand.  
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.  
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.  
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.  
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  
resistance as you draw the file along the depth gauge  
tool.  
Use the combination spanner to tighten the bar nuts  
while lifting the tip of the bar at the same time. Check that  
you can pull the chain round freely by hand and that it  
does not sag from the underside of the bar.  
The position of the chain tensioning screw on our chain saws  
varies from model to model. See instructions under the  
heading What is what? to find out where it is on your model.

GENERAL SAFETY PRECAUTIONS  
Checking chain lubrication  
Lubricating cutting equipment  
Check the chain lubrication each time you refuel. See  
instructions under the heading Lubricating the bar tip  
sprocket.  
WARNING! Poor lubrication of cutting  
equipment may cause the chain to snap,  
which could lead to serious, even fatal  
injuries.  
!
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.  
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.  
Never use waste oil! Using waste oil can be dangerous to  
you and damage the machine and environment.  
If the chain lubrication is not working:  
IMPORTANT! When using vegetable based saw chain oil,  
dismantle and clean the groove in the bar and saw chain  
before long-term storage. Otherwise there is a risk of the  
saw chain oil oxidizing, which will result in the saw chain  
becoming stiff and the bar tip sprocket jamming.  
Check that the oil channel in the bar is not obstructed.  
Clean if necessary.  
Filling with chain oil  
All our chain saws have an automatic chain lubrication  
system. On some models the oil flow is also adjustable.  
Check that the groove in the edge of the bar is clean.  
Clean if necessary.  
The saw chain oil tank and the fuel tank are designed so  
that the fuel runs out before the saw chain oil.  
However, this safety feature requires that you use the  
right sort of chain oil (if the oil is too thin it will run out  
before the fuel), and that you adjust the carburetor as  
recommended (a lean mixture may mean that the fuel  
lasts longer than the oil) and that you also use the  
recommended cutting equipment (a bar that is too long  
will use more chain oil).  
Check that the bar tip sprocket turns freely and that the

and lubricate if necessary.

GENERAL SAFETY PRECAUTIONS  
Chain drive sprocket  
Bar  
The clutch drum is fitted with one of the following drive  
sprockets:  
Check regularly:  
Whether there are burrs on the edges of the bar.Remove  
these with a file if necessary.  
A
B
Spur sprocket (the chain sprocket is welded on the drum)  
Rim sprocket (replaceable)  
Whether the groove in the bar has become badly worn.  
Replace the bar if necessary.  
Regularly check the degree of wear on the drive sprocket.  
Replace if wear is excessive. Replace the drive sprocket  
whenever you replace the chain.  
Needle bearing lubrication  
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.  
Both versions of sprockets have a needle bearing on the  
drive shaft, which has to be greased regularly (once a week).  
CAUTION! Use only high quality bearing grease or engine  
oil.  
See instructions under the heading Maintenance, Needle  
bearing lubrication.  
Checking wear on cutting equipment  
To prolong the life of the bar you should turn it over daily.  
Check the chain daily for:  
WARNING! Most chain saw accidents  
happen when the chain touches the  
operator.  
!
Wear personal protective equipment. See  
instructions under the heading Personal  
protective equipment.  
Visible cracks in rivets and links.  
Whether the chain is stiff.  
Do not tackle any job that you feel you are  
not adequately trained for. See instructions  
under the headings Personal protective  
equipment, How to avoid kickback, Cutting  
equipment and General working  
Whether rivets and links are badly worn.  
Replace the saw chain if it exhibits any of the points above.  
We recommend you compare the existing chain with a new  
chain to decide how badly the existing chain is worn.  
instructions.  
When the length of the cutting teeth has worn down to only  
0.16 inch (4 mm) the chain must be replaced.  
Avoid situations where there is a risk of  
kickback. See instructions under the  
heading Machine s safety equipment.  
Use the recommended protective  
equipment and check its condition. See  
instructions under the heading General  
working instructions.  
Check that all the chain saw safety features  
are working. See instructions under the  
headings General working instructions and  
General safety precautions.

ASSEMBLY  
Tension the chain by turning the chain tensioning screw  
clockwise using the combination spanner.  
Fitting the bar and chain  
WARNING! Always wear gloves, when  
working with the chain, in order to protect  
your hands from injury.  
!
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.  
Check that the chain brake is in disengaged position by  
moving the front hand guard towards the front handle.  
Remove the bar nuts and remove the clutch cover (chain  
brake). Take off the transportation ring (A).  
When fitting a new chain, the chain tension has to be  
checked frequently until the chain is run-in. Check the chain  
tension regularly. A correctly tensioned chain ensures good  
cutting performance and long life.  
Note: If clutch cover is difficult to remove, replace bar nuts,  
engage brake and rerelease (an audible click will be heard if  
released properly).  
Fit the bar over the bar bolts. Place the bar in its rearmost  
position. Place the chain over the drive sprocket locate it in  
the groove on the bar. Begin on the top edge of the bar.  
Make sure that the edges of the cutting links are facing  
forward on the top edge of the bar.  
Fit the clutch cover and locate the chain adjuster pin in the  
hole in the bar. Check that the drive links of the chain fit  
correctly over the drive sprocket and that the chain is  
correctly located in the groove in the bar.Tighten the bar nuts  
finger tight.

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

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

FUEL HANDLING  
It is important to use oil of the right grade (suitable  
viscosity range) to suit the air temperature.  
Fuel safety  
Never refuel the machine while the engine is running.  
In temperatures below 32°F (0°C) some oils become too  
viscous. This can overload the oil pump and result in  
damage to the oil pump components.  
Make sure there is plenty of ventilation when refuelling or  
mixing fuel (gasoline and 2-stroke oil).  
Move the machine at least 10 ft (3 m) from the refuelling  
point before starting it.  
Contact your service agent when choosing chain oil.  
Fueling  
WARNING! Taking the following  
precautions, will lessen the risk of fire:  
!
Do not smoke and do not place any hot  
objects in the vicinity of fuel.  
Never start the machine:  
1
If you have spilled fuel or chain oil on the machine.Wipe  
off the spillage and allow remaining fuel to evaporate.  
Always stop the engine and let it cool for a  
few minutes before refuelling.  
2
3
If you have spilled fuel on yourself or your clothes,  
change your clothes. Wash any part of your body that  
has come in contact with fuel. Use soap and water.  
When refuelling, open the fuel cap slowly  
so that any excess pressure is released  
gently.  
If the machine is leaking fuel. Check regularly for leaks  
from the fuel cap and fuel lines.  
Tighten the fuel cap carefully after  
refuelling.  
WARNING! Never use a machine with  
visible damage to the spark plug guard and  
ignition cable. A risk of sparking arises,  
which can cause a fire.  
!
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.  
Transport and storage  
Always store the chain saw and fuel so that there is no  
risk of leakages or fumes coming into contact with sparks  
or naked flames from electrical equipment, electric  
motors, relays/switches, boilers and the like.  
Always store fuel in an approved container designed for  
that purpose.  
For longer periods of storage or for transport of the chain  
saw, the fuel and chain oil tanks should be emptied. Ask  
where you can dispose of waste fuel and chain oil at your  
local gas station.  
Ensure the machine is cleaned and that a complete  
service is carried out before long-term storage.  
The bar guard must always be fitted to the cutting  
attachment when the machine is being transported or in  
storage, in order to prevent accident contact with the  
sharp chain. Even a non-moving chain can cause  
serious cuts to yourself or persons you bump into with an  
exposed chain.  
WARNING! Fuel and fuel vapor are highly  
flammable.Take care when handling fuel  
!
and chain oil. Be aware of the risks of fire,  
explosion and those associated with  
inhalation.  
Long-term storage  
Empty the fuel/oil tanks in a well ventilated area. Store the  
fuel in approved cans in a safe place. Fit the bar guard.  
Clean the machine. See instructions under the heading  
Maintenance schedule.

This should automatically set the stop switch to the start  
position.  
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.  
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 the machine has

WORKING TECHNIQUES  
Basic safety rules  
Before use:  
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.  
,
1
Check that the chain brake works correctly and is not  
damaged.  
2
3
Check that the rear right hand guard is not damaged.  
Check that the throttle lockout works correctly and is not  
damaged.  
4
Check that the stop switch works correctly and is not  
damaged.  
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.  
5
6
Check that all handles are free from oil.  
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.  
Check that the anti vibration system works and is not  
damaged.  
7
8
9
Check that the muffler is securely attached and not  
damaged.  
3
Take great care when removing small branches and  
avoid cutting bushes (i.e. cutting many small branches at  
the same time). Small branches can be grabbed by the  
chain and thrown back at you, causing serious injury.  
Check that all parts of the chain saw are tightened  
correctly and that they are not damaged or missing.  
Check that the chain catcher is in place and not  
damaged.  
10 Check the chain tension.  
General working instructions  
IMPORTANT!  
4
Make sure you can move and stand safely. Check the  
area around you for possible obstacles (roots, rocks,  
branches, ditches, etc.) in case you have to move  
suddenly. Take great care when working on sloping  
ground.  
This section describes basic safety rules for using a chain  
saw. This information is never a substitute for professional  
skills and experience. If you get into a situation where you  
feel unsafe, stop and seek expert advice. Contact your  
chain saw dealer, service agent or an experienced chain  
saw user.Do not attempt any task that you are not sure you  
can handle!  
Before using a chain saw you must understand the effects  
of kickback and how to avoid them. See instructions under  
the heading How to avoid kickback.  
Before using a chain saw you must understand the  
difference between cutting with the top and bottom edges  
of the bar. See instructions under the headings How to  
avoid kickback and Machine’s safety equipment.  
Wear personal protective equipment. See instructions  
under the heading Personal protective 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.  
22 – English

WORKING TECHNIQUES  
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.  
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.  
7
When you put the chain saw on the ground, lock the saw  
chain using the chain brake and ensure you have a  
constant view of the machine. Switch the engine off  
before leaving your chain saw for any length of time.  
4
Never use the chain saw above shoulder height and  
avoid cutting with the tip of the bar. Never use the  
chain saw one-handed!  
General rules  
1
If you understand what kickback is and how it happens  
then you can reduce or eliminate the element of surprise.  
By being prepared you reduce the risk. Kickback is  
usually quite mild, but it can sometimes be very sudden  
and violent.  
2
Always hold the chain saw firmly with your right hand on  
the rear handle and your left hand on the front handle.  
Wrap your fingers and thumbs around the handles.You  
should use this grip whether you are right-handed or left-  
handed. This grip minimizes the effect of kickback and  
lets you keep the chain saw under control.Do not let go  
of the handles!  
5
In order to keep control of your saw, always maintain a  
firm foothold. Never work on a ladder, in a tree or on any  
other insecure support.  
3
Most kickback accidents happen during limbing. Make  
sure you are standing firmly and that there is nothing in  
the way that might make you trip or lose your balance.  
Lack of concentration can lead to kickback if the kickback  
zone of the bar accidentally touches a branch, nearby  
tree or some other object.  
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

WORKING TECHNIQUES

Terms  
you.  
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:  
1
Make sure the cutting equipment will not jam in the cut.  
8
Unless the user resists this pushing force there is a risk  
that the chain saw will move so far backwards that only  
the kickback zone of the bar is in contact with the tree,  
which can lead to a kickback.  
2
Make sure the object you are cutting will not split.  
Cutting with the bottom edge of the bar, i.e. from the top  
of the object downwards, is known as cutting with a  
pulling chain. In this case the chain saw pulls itself  
towards the tree and the front edge of the chain saw body  
rests naturally on the trunk when cutting. Cutting with a  
pulling chain gives the operator better control over the  
chain saw and the position of the kickback zone.  
3
4
Make sure the chain will not strike the ground or any  
other object during or after cutting.  
Is there a risk of kickback?  
9
Follow the instructions on sharpening and maintaining  
your bar and chain.When you replace the bar and chain  
use only combinations that are recommended by us.See  
instructions under the headings Cutting equipment and  
Technical data.  
5
Do the conditions and surrounding terrain affect how  
safely you can stand and move about?  
Two factors decide whether the chain will jam or the object  
that you are cutting will split: the first is how the object is  
supported before and after cutting, and the second is  
whether it is in tension.  
Basic cutting technique  
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.  
In most cases you can avoid these problems by cutting in two  
stages; from the top and from the bottom.You need to  
support the object so that it will not trap the chain or split  
during cutting.  
!
General  
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.  
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).  
The following instructions describe how to handle the  
common situations you are likely to encounter when using a  
chain saw.  
Cutting from above = Cutting with a pulling chain.  
Cutting from below = Cutting with pushing chain.  
Cutting with a pushing chain increases the risk of kickback.  
See instructions under the heading How to avoid kickback.

WORKING TECHNIQUES  
Limbing  
If it is possible (can you turn the log?) stop cutting about 2/3  
of the way through the log.  
When limbing thick branches you should use the same  
approach as for cutting.  
Cut difficult branches piece by piece.  
2
1
3
Turn the log and finish the cut from the opposite side.  
Cutting  
The log is supported at one end. There is a high risk 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.  
Start by cutting from above (about 1/3 of the way through).  
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.  
Finish by cutting from below so that the two cuts meet.  
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.

WORKING TECHNIQUES  
The main point to avoid is letting the tree fall onto another  
Tree felling technique  
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.  
IMPORTANT! It takes a lot of experience to fell a tree.  
Inexperienced users of chain saws should not fell trees. Do  
not attempt any task beyond your experience level!  
Safe distance  
The safe distance between a tree that is to be felled and  
anyone else working nearby is at least 2 1/2 tree lengths.  
Make sure that no-one else is in this ”risk zone” before or  
during felling.  
IMPORTANT! During critical felling operations, hearing  
protectors should be lifted immediately when sawing is  
completed so that sounds and warning signals can be  
heard.  
Felling direction  
The aim is to fell the tree in a position where you can limb  
and cross-cut the log as easily as possible.You want it to fall  
in a location where you can stand and move about safely.  
Clearing the trunk and preparing your retreat  
Delimb the stem up to shoulder height. It is safer to work  
from the top down and to have the tree between you and the  
saw.  
Once you have decided which way you want the tree to fall  
you must judge which way the tree would fall naturally.  
Several factors affect this:  
Lean of the tree  
Bend  
Wind direction  
Arrangement of branches  
Weight of snow  
Obstacles within the reach of the tree: for example, other  
trees, power lines, roads and buildings.  
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.  
Look for signs of damage and rot in the stem, this makes  
it more probably that the tree will break and start to fall  
before you expect it to.  
Danger zone  
Felling direction  
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.  
Retreat path  
Danger zone  
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.

WORKING TECHNIQUES  
Felling  
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.  
WARNING! Unless you have special  
training we advise you not to fell trees with  
a diameter larger than the bar length of your  
saw!  
!
Make the felling cut about 1.5-2 inches (3-5 cm) above the  
bottom directional cut.  
Felling is done using three cuts. First you make the  
directional cuts, which consist of the top cut and the bottom  
cut, then you finish with the felling cut. By placing these cuts  
correctly you can control the felling direction very accurately.  
Directional cuts  
To make the directional cuts you begin with the top cut.  
Stand to the right of the tree and cut on the pull stroke.  
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.  
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°.  
All control over the felling direction is lost if the felling hinge  
is too narrow or non-existent, or if the directional cuts and  
felling cut are badly placed.  
The 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.

WORKING TECHNIQUES  
When the felling cut and directional cut are complete the tree  
Never work in the risk zone of the hanging trapped tree.  
should start to fall by itself or with the aid of a felling wedge  
or breaking bar.  
We recommend that you use a bar that is longer than the  
diameter of the tree, so that you can make the felling cut and  
directional cuts with single cutting strokes. See instructions  
under the heading Technical data section to find out which  
lengths of bar are recommended for your saw.  
The safest method is to use a winch.  
Tractor-mounted  
Portable  
There are methods for felling trees with a diameter larger  
than the bar length. However these methods involve a much  
greater risk that the kickback zone of the bar will come into  
contact with the tree.  
Cutting trees and branches that are in tension  
Preparations: Work out which side is in tension and where  
the point of maximum tension is (i.e. where it would break if  
it was bent even more).  
Freeing a tree that has fallen badly  
Decide which is the safest way to release the tension and  
whether you are able to do it safely. In complicated situations  
the only safe method is to put aside your chain saw and use  
a winch.  
Freeing a ”trapped tree”  
It is very dangerous to remove a trapped tree and there is  
high accident risk.  
General advice:  
Never try to fell the tree that is trapped.  
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.

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  
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

saw, bar and chain back at the user. If this  
happens when the chain is moving it can  
cause very serious, even fatal injuries. It is  
vital you understand what causes kickback  
and that you can avoid it by taking care and  
using the right working technique.  
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.  
Cutting the trunk into logs  
See instructions under the heading Basic cutting technique.  
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.

MAINTENANCE  
General  
Checking, maintaining and  
servicing chain saw safety  
equipment  
The user must only carry out the maintenance and service  
work described in this manual. More extensive work must be  
carried out by an authorised service workshop.  
Note! All servicing and repair work on the machine requires  
special training. This is especially true of the machines  
safety equipment. If your machine fails any of the checks  
described below we recommend you to contact our  
servicing dealer.  
Carburetor adjustment  
Your Husqvarna product has been designed and  
manufactured to specifications that reduce harmful  
emissions.  
AutoTune  
Chain brake and front hand guard  
If the engine is equipped with AutoTune, manual adjustment  
of the carburettor’s H and L needles and the T-screw no  
longer applies. Both needles and the T-screw have been  
removed. AutoTune is a function that adjusts the carburettor  
electronically, always resulting in optimal adjustment.  
Checking brake band wear  
Brush off any wood dust, resin and dirt from the chain brake  
and clutch drum. Dirt and wear can impair operation of the  
brake.  
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.  
The automatic adjustment of the carburettor means that  
the engine is adapted to local conditions, e.g.the climate,  
altitude, petrol and the type of 2-stroke oil. This function  
is controlled by AutoTune.  
Conditions  
CAUTION! There is an integrated speed governor in the  
ignition system that limits the maximum speed to 13600 rpm.  
When the speed governor is activated, you will get the same  
sound experience as when the chain saw 4-cycles.  
Regularly check that the brake band is at least 0.024 inch  
(0.6 mm) thick at its thinnest point.  
Checking the front hand guard  
Correctly adjusted carburetor  
A correctly adjusted carburettor means the machine  
accelerates without hesitation and it four-strokes a little at full  
throttle. In addition, the chain should not rotate when idling.  
Make sure the front hand guard is not damaged and that  
there are no visible defects such as cracks.  
Move the front hand guard forwards and back to make sure  
it moves freely and that it is securely anchored to the clutch  
cover.

MAINTENANCE  
Checking the inertia brake release  
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.  
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.  
Throttle lockout  
Make sure the throttle control is locked at the idle setting  
when the throttle lockout is released.  
When the bar hits the stump the brake should be  
applied.  
Press the throttle lockout and make sure it returns to its  
original position when you release it.  
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.  
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  
carburetor idle adjustment.  
Grasp the chain saw firmly, wrapping your fingers and  
thumbs around the handles.

MAINTENANCE  
Chain catcher  
Stop switch  
Check that the chain catcher is not damaged and is firmly  
attached to the body of the chain saw.  
Start the engine and make sure the engine stops when you  
move the stop switch to the stop setting.  
Muffler  
Right hand guard  
Check that the right hand guard is not damaged and that  
there are no visible defects, such as cracks.  
Never use a machine that has a faulty muffler.  
Vibration damping system  
Regularly check that the muffler is securely attached to the  
machine.  
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.  
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.  
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

pulley. Wind approx. 3 turns of the starter cord onto the  
pulley. Connect the pulley to the recoil spring so that the  
end of the spring engages in the pulley. Fit the screw in  
the center of the pulley. Insert the starter cord through  
the hole in the starter housing and the starter handle.  
Make a secure knot in the end of the starter cord.  
The muffler is designed to reduce the noise level and to  
direct the exhaust gases away from the operator. The  
exhaust gases are hot and can contain sparks, which may  
cause fire if directed against dry and combustible material.

Tensioning the recoil spring  
WARNING!When the recoil spring is wound  
up in the starter housing it is under tension  
and can, if handled carelessly, pop out and  
cause personal injury.  
Hook the starter cord in the notch in the pulley and turn  
the starter pulley about 2 turns clockwise.  
!
Note! Check that the pulley can be turned an additional  
1/2 turn when the starter cord is pulled all the way out.  
Care must be exercised when replacing the  
return spring or the starter cord. Wear  
protective glasses and protective gloves.

MAINTENANCE  
The filter can be cleaned more thoroughly by washing it in  
water and detergent.  
Fitting the starter  
To t 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.  
Fit and tighten the screws that hold the starter.  
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.  
Air filter  
Spark plug  
The air filter must be regularly cleaned to remove dust and  
dirt in order to avoid:  
The spark plug condition is influenced by:  
Carburettor malfunctions  
Starting problems  
Incorrect carburetor adjustment.  
An incorrect fuel mixture (too much or incorrect type of  
oil).  
Loss of engine power  
A dirty air filter.  
Unnecessary wear to engine parts  
Excessive fuel consumption.  
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.  
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.

These recommendations apply to Husqvarna’s chain oil, for  
other chain oils increase the oil flow by one step.  
WARNING! The engine must be stopped  
when making adjustments.  
!
Cooling system  
Needle bearing lubrication  
To keep the working temperature as low as possible the  
machine is equipped with a cooling system.  
The cooling system consists of:  
The clutch drum has a needle bearing on the output shaft.  
This needle bearing must be lubricated regularly (once a  
week).

Air intake on the starter.  
Air guide plate.  
When lubricating, remove the clutch cover by loosening the  
two bar nuts. Lay the saw on its side with the clutch drum  
upwards.  
Fins on the flywheel.  
Cooling fins on the cylinder.  
Cylinder cover (directs cold air over the cylinder).  
Lubrication involves engine oil dripping into the centre of the  
clutch drum as it rotates.  
Adjustment of the oil pump  
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.  
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 set to 1 turn open.  
Turning the screw clockwise will reduce the oil flow and  
turning the screw anti-clockwise will increase the oil flow.  
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.

Temperature 0 C (32 F) or colder:  
”Air Injection” centrifugal cleaning  
Centrifugal cleaning means the following: All air to the  
carburetor passes through the starter. Dirt and dust is  
pushed out by the cooling fan.  
Move the cover from position A to position B so that  
preheated air from the cylinder can pass into the carburettor  
compartment and prevent, e.g. the air filter icing up again.  
When fitting the winter cover in position B the centrifugal  
cleaning nozzle is blocked. This measure requires the air  
filter to be cleaned more regularly.  
IMPORTANT! In order to maintain operation of the  
centrifugal cleaning system it must be regularly maintained.  
Clean the air intake to the starter, the fins on the flywheel, the  
space around the flywheel, inlet pipe and carburetor  
compartment.  
Winter use  
Running problems can occur when using the machine in the  
cold and snowy conditions caused by:  
Too low engine temperature.

Special measures are therefore often required:  
Preheat the intake air to the carburetor by using the heat  
from the cylinder.  
For running the machine in cold weather or powder snow, a  
special cover is available, which is mounted on the starter  
housing. This reduces the intake of cold air and prevents  
large amounts of snow from being sucked in.  
Partly mask the air inlet on the starter to increase the  
working temperature of the engine.

AMERICAN STANDARD SAFETY PRECAUTIONS  
Other safety precautions  
Safety precautions for chain saw  
users  
(ANSI B 175.1-2000 Annex C)  
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.  
!
Kickback safety precautions  
WARNING! Kickback may occur when the  
nose or tip of the guide bar touches an  
object, or when the wood closes in and  
pinches the saw chain in the cut.  
!
Do not operate a chain saw when you are fatigued.  
Use safety footwear; snug-fitting clothing, protective gloves,  
and eye, hearing and head protection devices.  
Tip contact in some cases may cause a  
lightning fast reverse reaction, kicking the  
guide bar up and back towards the  
operator.  
Use caution when handling fuel. Move the chain saw at least  
10 feet (3 m) from the fueling point before starting the  
engine.  
Do not allow other persons to be near the chain saw when  
starting or cutting with the chain saw. Keep bystanders and  
animals out of the work area.  
Pinching the saw chain along the top of the  
guide bar may push the guide bar rapidly  
back towards the operator.  
Do not start cutting until you have a clear work area, secure  
footing and a planned retreat path from the falling tree.  
Either of these reactions may cause you to  
lose control of the saw which could result  
in serious personal injury.  
Keep all parts of your body away from the saw chain when  
the engine is running.  
Before you start the engine, make sure that the saw chain is  
not contacting anything.  
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.  
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.  
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.  
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.  
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 operate a chain saw in a tree unless you have been  
specifically trained to do so.  
Do not overreach or cut above shoulder height.  
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.
