SAFETY INSTRUCTIONS

CHAIN SAW SAFETY EQUIPMENT

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 these

instructions.

This section explains the various safety features of the saw,

how they work, and basic inspection and maintenance you

should carry out to ensure safe operation. (See the ”What is

what?” section to find out where these components are on Your

saw).

PERSONAL PROTECTIVE EQUIPMENT

NEVER USE A CHAIN SAW THAT HAS

FAULTY SAFETY EQUIPMENT! Carry out the

inspection, maintenance and service routines

listed in this section.

MOST CHAIN SAW ACCIDENTS HAPPEN

WHEN THE CHAIN TOUCHES THE OPERA-

TOR. You must wear approved protective

equipment whenever you use a chain saw.

Personal protective equipment cannot

eliminate the risk of injury but it will reduce

the degree of injury if an accident does

happen. Ask your chain saw dealer for help in

choosing the right equipment.

activate the chain brake.

Another important safety

feature is that it prevents

the chain from hitting your

left hand if you lose your

grip on the front handle.

Take care when using your

saw and make sure the

kickback zone of the bar

never touches any object.

You can also use the

chain brake as a

either be activated

manually (by your left

hand) or automatically by

the inertia release

mechanism (a free-

swinging pendulum). On

counterweight in case of

kickback.

temporary brake when you

change position or if you

put the saw down for a

short time. You should

also apply the chain brake

manually if there is a risk

of the chain accidentally

hitting anyone or anything

close by.

The brake is applied

when the front hand

guard (B) is pushed

forwards.

To release the chain brake

pull the front hand guard

backwards, towards the

front handle.

This movement activates

a spring-loaded

mechanism that tightens

the Brake Band (C)

around the engine drive

system (D) (Clutch Drum).

As mentioned in section A,

kickback can be very

sudden and violent.

Most kickbacks are

minor and do not always

activate the chain brake.

If this happens you

should hold the chain

saw firmly and not let

go.

SAFETY INSTRUCTIONS

The way the chain brake is triggered, either manually or

2 Throttle lock

automatically, 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 throttle lock is designed

to prevent accidental opera-

tion of the throttle control.

When you press the lock (A)

(i.e. when you grasp the

handle) it releases the throttle

trigger (B).

If you get a violent

kickback while the

kickback zone of the bar

is farthest away from you

the chain brake will be

activated by the

movement of the

counterweight (INERTIA

ACTIVATED).

When you release the handle

the throttle trigger and the

throttle lock both move back

to their original positions. This

movement is controlled by two

independent return springs.

This arrangement means that

the throttle control is

automatically locked at the

idle setting when you release

the handle.

3 Chain catcher

The chain catcher is designed

to catch the chain if it snaps or

jumps off. This should not

happen if the chain is properly

tensioned (see section on

”Assembly”) and if the bar and

chain are properly serviced

and maintained.

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.

(See section on ”General

working instructions”).

4 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.

During felling your left

hand grasps the front

handle in such a way that

it cannot activate the front

hand guard. In this

position the chain brake

can only be activated by

the inertia action of the

counterweight.

The inertia activated

chain brake increases

your safety but there are

certain factors to

remember (see point 6

above).

SAFETY INSTRUCTIONS

6 Stop switch

Use the stop switch to switch

off the engine.

5 Vibration damping system

Your chain saw is equipped

with a vibration damping

system that is designed to

minimise vibrations and make

operation easier.

When you use a chain saw

vibrations are generated by

the uneven contact between

the chain and the wood you

are cutting.

Cutting hardwoods (most

broadleaf trees) creates more

vibration than cutting

softwoods (most conifers).

Cutting with a chain that is

blunt or faulty (wrong type or

badly sharpened, see section

D) will increase the vibration

level.

7 Muffler

The muffler is designed to keep noise levels to a minimum and

to direct exhaust fumes away from the user.

The exhaust fumes from the engine are hot

and may contain sparks which can start a fire.

Never start the saw indoors or near

The vibration damping system

reduces the vibrations

transmitted from the engine

and chain to the handles of

the chain saw. The body of

the saw, including the cutting

equipment, is insulated from

the handles by vibration

damping units.

combustible material!

In countries with a hot climate

there is a high risk of forest

fires. Our chain saws are

therefore fitted with a SPARK

ARRESTOR MESH.

Check whether your saw is

fitted with such a mesh.

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.

These 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.

With this type of muffler it is

very important that you follow

the instructions on checking,

maintaining and servicing your

saw (see the section on

”Inspecting, maintaining and

servicing chain saw safety

equipment”).

The muffler gets very hot in use and remains

so for a short time afterwards. DO NOT

TOUCH THE MUFFLER IF IT IS HOT!

CUTTING EQUIPMENT

Never use a chain saw

This section describes how to choose and maintain your cutting

equipment in order to:

that has a faulty muffler.

• Reduce the risk of kickback.

• Reduce the risk of the chain breaking or jumping.

• Obtain maximum cutting performance.

• Extend the life of cutting equipment.

The 5 basic rules

Only use cutting

equipment

recommended by us!

See the ”Technical data”

section.

Regularly check that the

muffler is securely

attached to the chain saw.

Keep the chain cutting

teeth properly

sharpened! Follow our

instructions and use the

recommended file

gauge. A damaged or

badly sharpened chain

increases the risk of

accidents.

If the muffler on your saw

is fitted with a spark

arrestor mesh this must

be cleaned regularly. A

blocked mesh will cause

the engine to overheat

and may lead to serious

damage.

Maintain the correct

raker clearance! Follow

our instructions and

use the recommended

raker gauge. Too large a

clearance increases the

risk of kickback.

Never use a muffler if

the spark arrestor mesh

is missing or defective.

NEVER USE A CHAIN SAW WITH FAULTY

SAFETY EQUIPMENT. CARRY OUT THE

CHECKS AND MAINTENANCE MEASURES

DESCRIBED IN THIS SECTION. IF YOUR

CHAIN SAW FAILS ANY OF THESE CHECKS

CONTACT YOUR SERVICE AGENT TO GET IT

REPAIRED.

Keep the chain properly

tesioned! If the chain is

slack it is more likely to

jump off and lead to

increased wear on the

bar, chain and drive

sprocket.

Keep cutting equipment

well lubricated and

properly maintained!

performance from your chain.

A General information on sharpening cutting teeth

• Never use a blunt chain. When the chain is blunt you have to

exert more pressure to force the bar through the wood and

the cuttings will be very small. If the chain is very blunt it will

not produce any cuttings at all, just wood powder.

The following faults will increase the risk of

kickback considerably.

• A sharp chain eats its way

through the wood and

produces long, thick

cuttings.

•

SAFETY INSTRUCTIONS

Setting the raker clearance

C General advice on setting raker clearance

• When you sharpen the

cutting teeth you reduce the

RAKER CLEARANCE

(cutting depth). To maintain

cutting performance you

must file back the raker

teeth to the recommended

height.

• Before setting the raker clearance the cutting teeth should be

newly sharpened.

We recommend that you adjust the raker clearance every

third time you sharpen the chain. NOTE! This

recommendation assumes that the length of the cutting teeth

is not reduced excessively.

See the ”Technical data”

section to find the raker

clearance for your saw

chain.

• To adjust the raker

clearance you will need a

FLAT FILE and a RAKER

GAUGE.

• On a low-kickback cutting

link the front edge of the

raker lip is rounded. It is

very important that you

maintain this radius or bevel

when you adjust the raker

clearance.

• Place the gauge over the

raker lip.

• Place the file over the part

of the lip that protrudes

through the gauge and file

off the excess. The

clearance is correct when

you no longer feel any

resistance as you draw the

file over the gauge.

• We recommend the use of a

raker gauge to achieve the

correct clearance and bevel

on the raker lip.

The risk of kickback is increased if the raker

clearance is too large!

3 Tensioning the chain

A slack chain may jump off 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 saw chain has a running-in period during which

you should check the tension more frequently.

• Tension the chain as tightly

as possible, but not so tight

that you cannot pull it round

freely by hand.

Chain oil

• Chainsaw chain oil must demonstrate good adhesion to the

chain and also maintain its flow caracteristics regardless of

whether it is warm summer or cold winter weather.

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

HOW TOAVOID KICKBACK

Kickback can happen very suddenly and

violently; kicking the 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.

Check regularly:

• Whether there are burrs on

the edges of the bar.

Remove these with a file if

necessary.

What is kickback?

The word kickback is used to

describe the sudden reaction

that happens when the upper

quadrant of the tip of the bar

(known as the “kickback zone”)

touches an object and the

saw is kicked backwards.

• Whether the groove in the

bar has become badly worn.

Replace the bar if

necessary.

• Whether the tip of the bar is

uneven or badly worn. If a

hollow forms on one side of

the bar tip this is due to a

slack chain.

Kickback always occurs in

the cutting plane of the saw.

Normally the saw and bar are

thrown backwards and

upwards towards the user.

However the 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.

• To prolong the life of the bar

you should turn it over daily.

MOST CHAIN SAW ACCIDENTS HAPPEN

WHEN THE CHAIN TOUCHES THE

OPERATOR.

Kickback only occurs if the

kickback zone of the bar

touches an object.

•

WEAR PERSONAL PROTECTIVE EQUIPMENT

(see the section on ”Chain saw safety

equipment”).

•

DO NOT TACKLE ANY JOB YOU ARE UNSURE OF

(see the section on ”Personal protective

equipment”, ”How to avoid kickback”, ”General

working instructions” and ”Cutting equipment”).

•

AVOID SITUATIONS WHERE THERE IS A RISK OF

KICKBACK (see the section on ”Personal

protective equipment”).

USE THE RECOMMENDED PROTECTIVE

EQUIPMENT AND CHECK ITS CONDITION (see

section on ”General working instructions”).

CHECK THAT ALL SAFETY FUNCTIONS ARE

WORKING (see section on ”General working

SAFETY INSTRUCTIONS

FUEL SAFETY

(Refuelling, fuel mixture, storage.)

GENERAL SAFETY PRECAUTIONS

Chain saws are designed solely for cutting wood. The only

cutting equipment that can be used with this chain saw are

the combinations of bars and chains recommended in the

”Technical data” section.

Fuel and fuel vapour are highly inflammable.

Take care when handling fuel and chain oil.

Keep away from naked flames and do not

breathe in fuel vapour.

Never use a chain saw if

you are tired, if you have

drunk alcohol, or if you

are taking medication that

affects your vision, your

judgement or your co-

ordination.

• Never try to refuel the saw

while it is running.

• Make sure there is plenty of

ventilation when refuelling

or mixing fuel (2-stroke

mixture).

Always wear suitable protective clothing. See the section

on ”Personal protective equipment”.

• Move the saw at least 3 m

from the refuelling point

before starting it.

Never use a chain saw that has been modified in any way

from its original specification.

Min. 3 m

(10 ft)

• Never start the chainsaw:

a) If you have spilt fuel or

chain oil on the saw.

Wipe off the spill and

allow remaining fuel to

evaporate.

b) If you spill fuel or chain

oil on yourself or your

clothes. Change your

clothes.

Never use a chain saw

that is faulty. Carry out

the regular checks,

maintenance and service

routines described in this

manual. Some

maintenance and service

measures must be carried

out by trained specialists.

See the section on

c) If there is a fuel leak.

Check regularly for

leaks from the

”Maintenance”.

LINES.

STARTING

• Never start a chain saw

unless the bar, chain and

clutch cover are fitted

correctly. (See section on

”Assembly”).

•

Always store the chain saw and fuel away from any

sources of sparks or naked flames, e.g. machines, electric

motors, relays, switches, boilers, etc.

• Never start a chain saw

indoors. Exhaust fumes can

be dangerous.

•

Always store fuel in an approved container designed for

that purpose.

For longer periods of storage or for transport of the saw,

the fuel and chain oil tanks should be emptied. Ask where

you can dispose of waste fuel and chain oil at your local

petrol station.

• Before starting the saw

make sure there are no

people or animals nearby

who might be put at risk.

Never use any accessories other than those recommended

in this manual. See the sections on ”Cutting equipment”

and ”Technical data”.

• Place the saw on the

ground and hold the rear

handle down with your right

foot. Grasp the front handle

firmly using your left hand.

Make sure the chain saw is

steady and the chain is not

touching the ground. Then

grasp the starter handle

with your right hand and pull

the starter cord.

The risk of accident is increased if you use the

wrong cutting equipment or a chain that is not

sharpened correctly. Using the wrong combi-

nation of bar and chain can increase the risk

of accidents!

any distance.

Do not use the saw in bad weather, such as dense fog,

heavy rain, strong wind, intense cold, etc. Working in cold

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.

Never put a chain saw

down while the engine is

SAFETY INSTRUCTIONS

Two factors decide whether the chain will jam or the log will

split. The first is how the log is supported and the second is

whether it is in tension.

2 Basic cutting technique

General

• Always use full throttle when cutting!

In most cases you can avoid these problems by cutting in two

stages; from the top and from the bottom of the log. You need

to support the log so that it will not trap the chain or split during

cutting.

• Reduce the speed to idle after every cut (running the

engine for too long at full throttle without any load can lead to

serious engine damage).

• Cutting from above = Cutting on the pull stroke.

• Cutting from below = Cutting on the push stroke.

If the chain jams in the cut:

STOP THE ENGINE! Don’t try to pull the saw

free. If you do you may damage the chain

when the saw suddenly breaks free. Use a

Cutting

Limbing

General term for cutting through wood.

Cutting limbs off a felled tree.

The following instructions describe how to handle most types of

situation that you will be faced with when using a chain saw.

Splitting = When the object you are cutting breaks off

before the cut is complete.

Cutting

The log is lying on the

ground. There is little risk

of the chain jamming or

the log splitting. However

there is a risk that the

chain will touch the

ground when you finish

the cut.

There are five important factors you should consider

before making a cut:

Make sure the bar will not

jam in the cut.

Cut all the way through

the log from above. Try

not to touch the ground as

you finish the cut.

Maintain full throttle but

be prepared in case the

chain snatches.

Make sure the log will not

split.

Make sure the chain will

not strike the ground or

any other object during or

after cutting.

SAFETY INSTRUCTIONS

2 The log is supported at one

end. There is a high risk

that it will split.

3 Tree felling technique

It takes a lot of experience to fell a tree.

Inexperienced users of chain saws should not

fell trees. NEVER ATTEMPT A TASK YOU ARE

UNSURE OF.

Safe distance

A Start by cutting from

below (about 1/3 of the

way through).

The safe distance between a tree that is to be felled and

anyone else working nearby is at least 21/2 tree lengths. Make

sure that no-one else is in this "risk zone" before or during felling.

B Finish by cutting from

above so that the two

cuts meet.

3 The log is supported at both

ends. There is a high risk

that the chain will jam.

Felling direction

The aim is to fell the tree in the best possible position for

subsequent limbing and cross-cutting. You want it to fall on

ground where you can move about safely.

The main point to avoid is

letting the tree fall onto

another tree. It can be both

difficult and dangerous to

remove a tree in such a

position (see point 4 in this

section).

A Start by cutting from

above (about 1/3 of the

way through).

Once you have decided which

way you want the tree to fall

you must judge which way the

tree would fall naturally.

B Finish by cutting from

below so that the two

cuts meet.

Several factors affect this:

Lean of the tree

Bend

Wind direction

Limbing

Arrangement of branches

Weight of snow

When limbing thick branches

you should use the same

approach as for cutting.

Cut difficult branches piece by

piece.

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.

During critical felling operations, hearing

protectors should be lifted immediately when

sawing is completed so that sounds and

warning signals can be heard.

SAFETY INSTRUCTIONS

C Clearing the trunk and preparing your retreat

FELLING CUT

The felling cut is made from the opposite side of the tree and it

must be perfectly horizontal. Stand on the left side of the tree

and cut with the bottom edge of the bar.

Remove any branches that

are in the way. To do this it is

best to work from the top

down and keep the trunk

between you and the chain

saw. Never limb above

shoulder height.

Make the FELLING CUT

about 3-5 cm (1.5-2 inches)

above the flat section of the

DIRECTIONAL CUT.

Use full throttle and bring the

bar and chain 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 BREA-

KING BAR into the cut as

soon as it is deep enough.

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 behind the intended

felling direction.

Finish the FELLING CUT

parallel with the

DIRECTIONAL CUT LINE so

that the distance between

them is at least at least 1/10

of the trunk diameter. The

uncut section of the trunk is

called the BREAKING STRIP.

D Felling

Felling is done using three cuts. First you make the

DIRECTIONAL CUTS, which consist of the TOP CUT and the

BOTTOM CUT; followed by the FELLING CUT. By placing

these cuts correctly you can control the felling direction very

accurately.

The BREAKING STRIP act as

hinges that control the felling

direction of the falling tree.

DIRECTIONAL CUT

To make the DIRECTIONAL

CUT you begin with the TOP

CUT. Stand to the right of the

tree and cut downwards at an

angle.

All control over the felling

direction is lost if the BREA-

KING STRIP is too narrow or

if the directional cut and felling

cut are badly placed.

Next make the BOTTOM CUT

so that it finishes at the end of

the TOP CUT.

The directional cut should run

1/4 of the diameter through

the trunk and the angle

between the TOP CUT and

BOTTOM CUT should be 45°.

When the felling cut and

directional cut are complete

the tree should start to fall

under its own weight or with

the aid of a FELLING WEDGE

or BREAKING BAR.

The line where the two cuts

meet is called the

DIRECTIONAL CUT LINE.

This line should be perfectly

horizontal and at right angles

(90°) to the chosen felling

direction.

SAFETY INSTRUCTIONS

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 CUT

with single cutting stokes.

(See ”Technical data” to find

out which lengths of bar are

recommended for your saw).

4 Freeing a tree that has fallen badly = high

accident risk

Freeing a “Trapped tree”

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:

UNLESS YOU HAVE SPECIAL TRAINING WE

ADVISE YOU NOT TO FELL TREES WITH A

DIAMETER LARGER THAN THE BAR LENGTH

OF YOUR SAW!

a) Work out which way the tree or branch will move if released

and where the natural “BREAKING POINT” is (i.e. the place

it would break if it was bent even more).

Limbing

MOST KICKBACK ACCIDENTS HAPPEN

DURING LIMBING!PAY CLOSE ATTENTION

TO THE POSITION OF THE KICKBACK ZONE

OF THE BAR WHEN YOU ARE LIMBING

BRANCHES THAT ARE IN TENSION!

b) 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.

Make sure there are no

obstacles in your way. Work

on the left side of the trunk.

Work close to the saw for

maximum control. If possible,

let the weight of the saw rest

on the trunk.

General advice:

a) Position yourself so that

you will be clear of the

tree or branch when it

springs free.

Keep the tree between you

and the saw as you move

along the trunk.

b) Make one or more cuts at

or near the BREAKING

POINT. Make as many

cuts of sufficient depth as

necessary to reduce the

tension and make the tree

or branch break at the

BREAKING POINT.

FUEL HANDLING

Mixing

• Always mix the gasoline

Fuelmix

and oil in a clean container

intended for fuel.

IMPORTANT! The chain saw is equipped with a two-stroke

engine and must always been run using a mixture of gasoline

and two-stroke engine 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.

• 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.

Always provide for good ventilation when

handling fuel.

• Use good quality unleaded

gasoline.

• If the saw is not used for

some time the fuel tank

should be emptied and

cleaned.

• The lowest recommended

octane rating is 87. If you

run the engine on lower

octane rating than 87 so-

called “knocking“ can occur.

This leads to an increased

Two-stroke oil

• For the best results use HUSQVARNA two-stroke oil, which is

especially developed for chain saws. Mixing ratio 1:50 (2%).

• Never use two-stroke oil intended for water cooled outboard

engines, so-called, outboard oil.

FUEL HANDLING

Fuelling

Taking the following precautions, will lessen

the risk of fire.

• Do not smoke or place warm objects in the vicinity of

the fuel.

• Always shut off the engine before refuelling.

• Slowly open the fuel cap, when filling fuel, so that

possible overpressure is slowly released.

• Tighten the fuel cap carefully after fuelling.

• Always move the saw from the fuelling area before

starting.

Clean around the fuel cap.

Clean the fuel and chain oil

tanks regularly. The fuel filter

should be changed at least

once a year. Contamination in

the fuel tanks causes

malfunction. Make sure the

fuel is well mixed by shaking

the container before fuelling.

The volume of chain oil and

fuel tanks are adjusted to

each other. Therefore, always

fill chain oil and fuel at the

same time.

MAINTENANCE

Conditions

Carburetor

• Before any adjustments are made the air filter should be

clean and the cylinder cowling fitted. Adjusting the carburetor

while a dirty air filter is in use will result in a leaner mixture

when the filter is finally cleaned. This can give rise to serious

engine damage.

Your Husqvarna product has been designed and manufactured

to specifications that reduce harmful emissions.

After your unit has been run 8-10 tanks of fuel the engine has

broken in. To ensure that your unit is at peak performance and

producing the least amount of harmful emissions after break in,

have your authorized servicing dealer, who has a revolution

counter at his disposal, to adjust your carburetor for optimum

operating conditions.

• Carefully turn the L and H needle to the mid point.

• Do not attempt to adjust the needles beyond the stops as

damage can occur.

• Now start the saw according to the starting instructions and

run it warm for 10 minutes.

Functioning, Basic setting, Final setting

NOTE! If the chain rotates the T screw should be turned

counter-clockwise until the chain stops.

WARNING! Do not start the saw without the

bar, chain and clutch cover (chain brake)

assembled. If you do, the clutch might come

loose and cause severe injuries.

• Place the saw on a flat surface so that the bar points away

from you and so that the bar and chain do not come into

contact with the surface or other objects.

Low speed needle L

Operation

Turn the low speed needle L clockwise until the stop. If the

engine has bad acceleration or erratic idling, turn the L needle

counter-clockwise until good idling and acceleration.

• The carburetor governs the engine speed via the throttle. Air/

fuel are mixed in the carburetor. The air/fuel mixture is

adjustable. To take advantage of the engine’s optimal output

the setting must be correct.

NOTE! If the chain rotates in the idling position, turn the

idling speed screw counter-clockwise until the chain stops.

• The setting of the carburetor means that the engine is

adapted to local conditions, for example, the climate, altitude,

fuel and the type of 2-stroke oil.

Final setting of the idling speed T

Adjust the idling speed with the screw T. If it is necessary to re-

adjust, first turn the idle speed adjusting screw T clockwise, until

the chain starts to rotate. Then turn, counter-clockwise until the

chain stops. A correctly adjusted idle speed setting occurs

when the engine runs smoothly in every position. It should also

be good margin to the rpm when the chain starts to rotate.

• The carburetor has three

adjustment possibilities:

L = Low speed jet.

H = High speed jet.

T = Adjustment screw for

idling.

Contact your servicing dealer, if the idle speed

setting cannot be adjusted so that the chain

stops. Do not use the saw until it has been

properly adjusted or repaired.

• The fuel quantity required in relation to the air flow, provided

by opening the throttle, is adjusted by the L and H-jets. If they

are screwed clockwise the air/fuel ratio becomes leaner (less

fuel) and if they are turned counter-clockwise the ratio

becomes richer (more fuel). A leaner mixture gives a higher

engine speed and a richer mixture give a lower engine speed.

• The T screw regulates the idling speed. If the screw T is

turned clockwise this gives a higher idling speed; counter-

clockwise a lower idling speed.

High speed needle H

The high speed needle H

influences the power of the

saw. A too lean adjusted high

speed needle H (high speed

needle H closed too much)

gives overrevs and damages

the engine. Turn the high

speed needle H counter-

clockwise until the stop. If the

engine runs roughly, turn the

high speed needle slowly the

minimum amount clockwise

until the engine runs smoothly.

The high speed needle H is correctly set when the saw ”4-

cycles” a little. If the saw ”whistles” the setting is too lean. If

there is too much exhaust gas at the same time as the saw ”4-

cycles” much, the setting is too rich. Turn the high speed needle

H until the setting sounds correct. NOTE! For optimum setting

of the carburetor, contact a qualified servicing dealer who

has a revolution counter at his disposal.

Basic setting and running in

The carburetor is set to its basic setting when test run at the

factory. The basic setting is richer than the optimal setting and

should be kept during the machine‘s first working hours.

Thereafter the carburetor should be finely adjusted. Fine

adjustment should be carried out by a skilled technician.

NOTE! If the chain rotates while idling the T screw should be

adjusted counter-clockwise until it stops.

Recommended idling speed: 2 500 rpm.

Contact your servicing dealer, if the idle speed

setting cannot be adjusted so that the chain

stops. Do not use the saw until it has been

Correctly adjusted carburetor

A correctly adjusted carburetor means that the saw accelerates

without hesitation and the saw 4-cycles a little at max speed.

Furthermore, the chain must not rotate at idling. A too lean

adjusted low speed needle L may cause starting difficulties and

MAINTENANCE

Tensioning the recoil spring

Starter device

• Lift the starter cord up in the

notch on the starter pulley

and turn the starter pulley 2

turns clockwise.

WARNING!

• When the recoil spring is assembled in the starter

housing, it is in tensioned position and can when

treated carelessly, pop out and cause injuries.

• Always be careful, when changing the recoil spring or

the starter cord. Always wear safety goggles for eye

protection.

NOTE! Check that the

starter pulley can be turned

at least half a turn, when the

starter cord is entirely pulled

out.

Changing a broken or worn

starter cord

Changing the broken recoil spring

• Lift the starter pulley (see

"Changing a broken or worn

starter cord").

• Loosen the screws, that

hold the starter device

against the crankcase and

remove the starter device.

• The recoil spring is

disassembled from the

starter device, with its inside

facing down. Tap the starter

lightly against a working

bench or similar. If the

spring pops out when

assembling, it should be

mounted again, out and in

towards the centre.

• Pull out the cord approx. 30

cm and lift it up into the

notch in the pulley. Zero-set

the recoil spring by letting

the pulley rotate slowly

backwards. Undo the screw

in the centre of the pulley

and remove the pulley.

• Lubricate the recoil spring

with thin oil. Assemble the

starter pulley, and tension

the recoil spring.

• Insert and fasten a new

starter cord in the pulley.

Wind approx. 3 turns of the

starter cord on to the pulley.

Assemble the starter pulley

against the recoil spring, so

the end of the spring

engages to the pulley. Fit

the screw in the centre of

the pulley. Carry the starter

cord through the hole in the

starter housing and the

starter handle. Make a knot

on the starter cord.

Starter device assembly

• Assemble the starter

device, by pulling the starter

cord out first, then place the

starter against the

crankcase. Then slowly

release the starter cord so

that the pulley engages with

the pawls.

• Assemble and tighten the

screws, which hold the

starter.

MAINTENANCE

Muffler

Air filter

The air filter must be regularly cleaned from dust and dirt in

order to avoid:

• Carburetor malfunctions

• Starting problems

• Engine power reduction

• Unnecessary wear on

the engine parts

The muffler is designed in

order 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.

• Abnormal fuel consumption

Clean the air filter daily or

more often if the air is

exceptionally dusty in the

working area.

• Disassemble the air filter by

removing the cylinder cover

and unscrew the filter.

When reassembling, make

sure that the filter is tight

against the filter holder.

Clean the filter by brushing

or shaking it.

Some mufflers are equipped

with a special screen. If your

saw has this type of muffler,

you should clean the screen

at least once a week. This is

done with a wire brush.

CAUTION! The screen must

be replaced, if damaged. The

saw will be overheated, if the

screen is clogged. This results

in damage on the cylinder and

the piston. Never use a saw

with a clogged or defective

muffler.

• A more thorough cleaning of

the filter is obtained by

washing it in water and

soap.

An air filter, which is used for

some time, cannot be cleaned

completely. Therefore it must

be replaced by a new one,

with regular intervals.

Adjusting the oil pump

IMPORTANT! A damaged air

filter must always be

replaced.

The oil pump can be adjusted

to give four different oil flow

rates. To adjust the flow rate,

first remove the chain, bar,

clutch cover, centrifugal clutch

and the clutch drum. Using a

screwdriver, adjust the oil flow

rate by turning the adjuster

screw one way or the other.

The projection on the screw

should point towards the

chosen setting. The diagram

shows the setting for flow rate

Spark plug

0,5 mm

The spark plug condition is

influenced by:

• An incorrect carburetor

setting.

• Wrong fuel mixture (too

much oil in the gasoline).

• A dirty air filter.

These factors cause deposits

on the spark plug electrodes,

which may result in

malfunction and starting

difficulties. If the engine is

low on power, difficult to

start or runs poorly at idling

speed, always check the

spark plug first.

Recommended settings:

18" bars

Setting 2

20" bars and longer Setting 3-4

NOTE! Do not carry out this adjustment with the engine

running!

If the spark plug is dirty, clean it and check the electrode gap.

Readjust if necessary. The correct gap is 0,5 mm (0,020").

The spark plug should be replaced after about a month in

operation or earlier if the electrodes are badly eroded.

IMPORTANT! Always use the recommended spark plug type.

An incorrect spark plug can severely damage the piston/

cylinder.

MAINTENANCE

Needle bearing maintenance

Winter use

During winter time, powder snow and cold weather can cause

running problems, such as:

• Too low engine temperature.

• Icing on the air filter and carburetor.

The clutch drum is equipped

with one of the following chain

sprockets:

Therefore some special measures are required:

• Partly reduce the air inlet of the starter and by doing that

increase the engine temperature.

• Preheat the intake air to the carburetor by removing the

special plug between the cylinder and the carburetor space.

• Spur sprocket (A) (the chain

sprocket is welded on the

drum)

Temperature 0^oC (32^oF) or colder

• Rim sprocket (B)

(exchangeable)

Twist the cover flap so that

preheated air from the

cylinder can enter the

carburetor chamber to prevent

icing of the filter.

Both versions have built-in

needle bearing at the drive

shaft, whitch has to be

greased regularly (once a

week).

NOTE! Use only high

quality bearing grease.

Temperature -5^oC (23^oF) or colder

When using the saw in cold

weather or powder snow

conditions you should cover

the starter unit with adhesive

tape. This reduces the flow of

cold air and prevents large

amounts of snow from being

sucked in.

Cooling system

IMPORTANT! If a special

winter kit is assembled or

measures are taken to

increase the engine

temperature, a readjustment

to normal setting has to be

done when the saw is used

under normal conditions.

Otherwise, there is a risk of

overheating, which can

cause severe engine

To obtain the lowest possible running temperature the saw is

equipped with a cooling system.

The cooling system

consists of:

1. Air intake on the starter

unit.

2. Air guide plate.

3. Fan blades on the

flywheel.

damage.

IMPORTANT! Any maintenance other than that described in

this manual must be carried out by your servicing dealer.

4. Cooling fins on the

cylinder.

5. Cylinder cowling

(supplies cold air over

the cylinder).

Clean the cooling system with a brush once a week, more often

in demanding conditions. A dirty or blocked cooling system

results in the saw overheating which causes damage to

piston and cylinder.
