SAFETY INSTRUCTIONS

Personal protective equipment

IMPORTANT! Whenever you use a clearing saw,
brushcutter or trimmer you must wear personal protective
equipment that is approved by the authorities. Personal
protective equipment does not eliminate the risk of
accidents, but it can reduce the effects of an injury in the
event of an accident. Ask your dealer for help when
choosing protective equipment.

WARNING! Listen out for warning signals or
shouts when you are wearing hearing

!

protection. Always remove your hearing
protection as soon as the engine stops.

HELMET
A helmet should be worn if the trees being cleared are taller
than 2 m.

HEARING PROTECTION
Wear hearing protection that provides adequate noise
reduction.

FIRST AID KIT
Always have a first aid kit nearby.

Machine ′′

s safety equipment

WARNING! Never use a machine that has
faulty safety equipment! Carry out the
inspection, maintenance and service
routines listed in this section.

Throttle lock

The throttle lock 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 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.

EYE PROTECTION
Always wear approved eye protection. If you use a visor then
you must also wear approved protective goggles. Approved
protective goggles must comply with standard ANSI Z87.1 in
the USA or EN 166 in EU countries. Visors must comply with
standard EN 1731.

GLOVES
Gloves should be worn when necessary, e.g., when fitting
cutting attachments.

BOOTS
Wear sturdy, non-slip boots.

Stop switch

Use the stop switch to switch off the engine.

Cutting attachment guard

This guard is intended to prevent loose objects from being
thrown towards the operator. The guard also protects the
operator from accidental contact with the cutting attachment.

CLOTHING
Wear clothes made of a strong fabric and avoid loose clothing
that can catch on twigs and branches. Always wear heavy,
long pants. Do not wear jewellery, shorts sandals or go
barefoot. Secure hair so it is above shoulder level.

WARNING! Never use a cutting attachment
without an approved guard. See the chapter

!

on Technical data. If an incorrect or faulty
guard is fitted this can cause serious
personal injury.

SAFETY INSTRUCTIONS

Vibration damping system

Your machine is equipped with a vibration damping system
that is designed to minimize vibration and make operation
easier.

Using incorrectly wound cord or a blunt or incorrect cutting
attachment (wrong type or incorrectly filed, see instructions
under the heading Filing the blade) increases the level of
vibration.

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

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. The risk
increases at low temperatures.

Quick release

There is an easily accessible, quick release fitted at the front
as a safety precaution in case the engine catches fire, or in
any other situation that requires you to free yourself from the
machine and harness. See instructions under the heading
Adjusting the harness and clearing saw.

In countries that have a warm and dry climate there is a
significant risk of fire. We therefore fit certain mufflers with a
spark arrestor mesh. Check whether the muffler on your
machine is fitted with this kind of mesh.

For mufflers it is very important that you follow the instructions
on checking, maintaining and servicing your machine. See
instructions under the heading Checking, maintaining and
servicing the machine’s safety equipment.

WARNING! Mufflers fitted with catalytic
converters get very hot during use and

!

remain so for some time after stopping. This
also applies at idle speed. Contact can result
in burns to the skin. Remember the risk of
fire!

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! Bear in mind that: Engine
exhaust fumes contain carbon monoxide,

!

which can cause carbon monoxide
poisoning. For this reason you should not
start or run the machine indoors, or
anywhere that is poorly ventilated.

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!

Cutting equipment

Saw blades are intended for cutting fibrous types of wood.

Muffler

The muffler is designed to keep noise levels to a minimum and
to direct exhaust fumes away from the user. A muffler fitted
with a catalytic converter is also designed to reduce harmful
exhaust gases.

Grass blades and grass cutters are intended for cutting
coarse grass.

A trimmer head is intended for trimming grass.

Cutting equipment

This section describes how to choose and maintain your
cutting equipment in order to:

• Reduce the risk of kickback.

• Obtain maximum cutting performance.

• Extend the life of cutting equipment.

General rules

1 Only use cutting attachments with the guards we

recommend! See the chapter on Technical data.

2 Keep the teeth of the blade correctly sharpened! Follow

our instructions and use the recommended file gauge. An
incorrectly sharpened or damaged blade increases the
risk of accidents.

• Never use a machine that has a faulty muffler.

• Regularly check that the muffler is securely attached to
the machine.

• If the muffler on your machine is fitted with a spark arrestor
mesh then it should be cleaned regularly. A blocked mesh
causes the engine to overheat, which can lead to serious
damage. Never use a muffler with a defective spark
arrestor mesh.

3 Maintain the correct blade setting! Follow our instructions

and use the recommended blade setting tool. An
incorrectly set blade increases the risk of jamming and
kickback.

4 Check the cutting attachment for damage or cracks. A

damaged cutting attachment should always be replaced.

SAFETY INSTRUCTIONS

Locking nut

• When fitting, tighten the nut in the opposite direction to the
direction of rotation of the cutting attachment. To remove
it, undo the nut in the same direction as the cutting
attachment rotates. (CAUTION! The nut has a left-hand
thread.)

• Tighten the nut using the socket spanner. 35-50 Nm (3.5­5 kpm).

CAUTION! The nylon lining inside the locking nut must not

be so worn that you can turn it by hand. The lining should
offer a resistance of at least 1.5 Nm. The nut should be
replaced after it has been put on approx. 10 times.

WARNING! Never use a machine with faulty
safety equipment. The machine’s safety

!

equipment must be checked and maintained
as described in this section. If your machine
fails any of these checks contact your
service agent to get it repaired.

Filing the saw blade

• See the cutting attachment packaging for correct
sharpening instructions.

• A correctly filed blade is essential for working efficiently
and to avoid unnecessary wear to the blade and clearing
saw.

• Make sure that the blade is well supported when you file
it. Use a 5.5 mm round file with a file holder.

• The filing angle is 15 ° . File alternate teeth to the right and
those in between to the left. If the blade has been heavily
pitted by stones it may be necessary to dress the top
edges of the teeth with a flat file, in exceptional cases. If
so, this should be done before filing with a round file. The
top edges must be filed down by the same amount for all
the teeth.

Cutting equipment

IMPORTANT!

This section describes how to choose and maintain your
cutting equipment in order to:

Reduce the risk of kickback.

Obtain maximum cutting performance.

Extend the life of cutting equipment.

Only use cutting attachments with the guards we
recommend! See the chapter on Technical data.

Refer to the instructions for the cutting attachment to check
the correct way to load the cord and the correct cord
diameter.

Keep the teeth of the blade correctly sharpened! Follow our
recommendations. Also refer to the instructions on the
blade packaging.

Maintain the correct blade setting! Follow our instructions
and use the recommended file gauge.

WARNING! Using an incorrect cutting
attachment or an incorrectly sharpened

!

blade increases the risk of kickback.

• Adjust the blade setting. This should be 1 mm.

Sharpening grass cutters and grass blades

• See the cutting attachment packaging for correct
sharpening instructions.

• Sharpen blades and cutters using a single-cut flat file.

• Sharpen all edges equally to maintain the balance of the
blade.

SAFETY INSTRUCTIONS

Trimmer head

• Only use the recommended trimmer heads and trimmer
cords. These have been tested by the manufacturer to suit
a particular engine size. This is especially important when
a fully automatic trimmer head is used. Only use the
recommended cutting attachment. See the chapter on
Technical data.

• Smaller machines generally require small trimmer heads
and vice versa. This is because when clearing using a
cord the engine must throw out the cord radially from the
trimmer head and overcome the resistance of the grass
being cleared.

• The length of the cord is also important. A longer cord
requires greater engine power than a shorter cord of the
same diameter.

• Make sure that the cutter on the trimmer guard is intact.
This is used to cut the cord to the correct length.

• To increase the life of the cord it can be soaked in water
for a couple of days. This will make the line tougher so that
it lasts longer.

IMPORTANT! Always ensure the trimmer cord is wound
tightly and evenly around the drum, otherwise the machine
will generate harmful vibration.

WARNING! Always stop the engine before
doing any work on the cutting attachment.

!

This continues to rotate even after the
throttle has been released. Ensure that the
cutting attachment has stopped completely
and disconnect the HT lead from the spark
plug before you start to work on it.

General safety precautions

IMPORTANT!

The machine is only designed for trimming grass, grass
clearing and/or forestry clearing.

The only accessories you can operate with this engine unit

sure the spark plug cap and HT lead are not damaged.
Otherwise you could get an electric shock.

The machine operator must ensure that no people or
animals come closer than 15 metres while working. When
several operators are working in the same area the safety
distance should be at least twice the tree height and no less
than 15 metres.

WARNING! Using an incorrect cutting
attachment or an incorrectly filed blade can

!

increase the risk of accidents.

Starting

WARNING! When the engine is started with
the choke in either the choke or start throttle

!

positions the cutting attachment will start to
rotate immediately.

• The complete clutch cover and shaft must be fitted before
the machine is started, otherwise the clutch can come

SAFETY INSTRUCTIONS

• Place the machine on the ground, ensure the cutting
attachment is clear of twigs and stones. Hold the body of
the machine on the ground using your left hand
(CAUTION! Not with your foot). Then grip the starter
handle with your right hand and pull the starter cord.

Fuel safety

• Always use a fuel container with an anti-spill valve.

• Never refuel the machine while the engine is running.
Always stop the engine and let it cool for a few minutes
before refuelling.

• Make sure there is plenty of ventilation when refuelling or
mixing fuel (gasoline and 2-stroke oil).

• Move the machine at least 3 m from the refuelling point
before starting it.

• Never start the machine:

1 If you have spilt fuel on it. Wipe off the spillage and

allow remaining fuel to evaporate.

2 If you have spilt 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.

3 If the machine is leaking fuel. Check regularly for leaks

from the fuel cap and fuel lines.

4 Avoid all skin contact with fuel. Fuel is a skin irritant

and may even cause skin changes.

• The transport guard must always be fitted to the cutting
attachment when the machine is being transported or in
storage.

WARNING! Take care when handling fuel.
Bear in mind the risk of fire, explosion and

!

inhaling fumes.

General working instructions

IMPORTANT!

This section describes the basic safety precautions for
working with clearing saws and trimmers.

If you encounter a situation where you are uncertain how to
proceed you should ask an expert. Contact your dealer or
your service workshop.

Avoid all usage which you consider to be beyond your
capability.

You must understand the difference between forestry
clearing, grass clearing and grass trimming before use.

Basic safety rules

1 Look around you:

- To ensure that people, animals or other things cannot

affect your control of the machine.

- To ensure that people, animals, etc., do not come into

contact with the cutting attachment or loose objects
that are thrown out by the cutting attachment.

- CAUTION! Do not use the machine unless you are

able to call for help in the event of an accident.

2 Do not use the machine in bad weather, such as dense

fog, heavy rain, strong wind, intense cold, etc. Working in
bad weather is tiring and often brings added risks, such as
icy ground, unpredictable felling direction, etc.

3 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.

Transport and storage

• Store and transport the machine and fuel so that there is
no risk of any leakage or fumes coming into contact with
sparks or naked flames, for example, from electrical
machinery, electric motors, electrical relays/switches or
boilers.

• When storing and transporting fuel always use approved
containers intended for this purpose.

• When storing the machine for long periods the fuel tank
must be emptied. Contact your local gas station to find out
where to dispose of excess fuel.

4 Switch off the engine before moving to another area. Fit

the transport guard before carrying or transporting the
equipment any distance.

5 Never put the machine down with the engine running

unless you have it in clear sight.

SAFETY INSTRUCTIONS

Adjusting the harness and clearing saw

WARNING! When using a clearing saw it
must always be hooked securely to the

!

harness. Otherwise you will be unable to
control the clearing saw safely and this can
result in injury to yourself or others. Never
use a harness with a defective quick release.
Always use a double harness that
distributes the load across both shoulders.

Safety release

At the front is an easily accessible, quick release. Use this if
the engine catches fire or in any other emergency situation
that requires you to free yourself from the machine and
harness.

Correct balance

Let the cutting attachment rest lightly on the ground. If you
use a saw blade it should balance about 10 cm above the
ground to prevent contact with stones and the like. Adjust the
position of the support hook to balance the clearing saw
correctly.

Basic working techniques

• Always slow the engine to idle speed after each working
operation. Long periods at full throttle without any load on
the engine can lead to serious engine damage.

Terms

• Use a saw blade for cutting woody growth with thin stems.

Spreading the load on your shoulders

A well-adjusted harness and machine makes work much
easier. Adjust the harness for the best working position.
Tension the side straps so that the weight is evenly distributed
across both shoulders.

Correct height

Adjust the shoulder strap so that the cutting attachment is
parallel to the ground.

• Use a grass cutter or grass blade for clearing grass.

• Use a trimmer head or plastic blades for lighter clearing
work, for example along verges or around trees.

WARNING! Sometimes branches or grass
get caught between the guard and cutting

!

attachment. Always stop the engine before
cleaning.

SAFETY INSTRUCTIONS

The ABC of clearing

Always use the correct equipment.

Make sure the equipment is well adjusted.

Follow the safety precautions.

Organise your work carefully.

Always use full throttle when starting to cut with the blade.

Always use sharp blades.

Avoid stones.

WARNING! Avoid cutting with the area of the
blade between the 12 o’clock and 3 o’clock

!

positions. Because of the speed of rotation
of the blade kickback can occur if you
attempt to cut thick stems with this area of
the blade.

Working methods

• Before you start clearing, check the clearing area, the type
of terrain, the slope of the ground, whether there are
stones, hollows etc.

• On sloping ground you should work along the slope. It is
much easier to work along a slope than it is to work up and
down it.

• The strip should be planned so that you avoid going over
ditches or other obstacles on the ground.

Brush cutting with a saw blade

• Cut through thin stems and brush. Work with a sawing
movement, swinging sideways.

Grass clearing using a grass blade

• Grass blades and grass cutters must not be used on
woody stems.

• A grass blade is used for all types of tall or coarse grass.

• The grass is cut down with a sideways, swinging
movement, where the movement from right-to-left is the
clearing stroke and the movement from left-to-right is the
return stroke. Let the left-hand side of the blade (between
8 and 12 o’clock) do the cutting.

• If the blade is angled to the left when clearing grass, the
grass will collect in a line, which makes it easier to collect,
e.g. by raking.

• Try to work rhythmically. Stand firmly with your feet apart.
Move forward after the return stroke and stand firmly
again.

• Let the support cup rest lightly against the ground. It is
used to protect the blade from hitting the ground.

• Reduce the risk of material wrapping around the blade by
following these instructions:

1 Always work at full throttle.

2 Avoid the previously cut material during the return

stroke.

• Stop the engine, unclip the harness and place the
machine on the ground before you start to collect the cut
material.

• Avoid cutting with the area of the blade between the 12
o’clock and 3 o’clock positions.

WARNING! Neither the operator of the
machine nor anyone else may attempt to

!

remove the cut material while the engine is
running or the blade is rotating, as this can
result in serious injury.

Stop the engine and blade before you
remove material that has wound around the
blade shaft as otherwise there is a risk of
injury. The bevel gear can get hot during use
and may remain so for a while afterwards.
You could get burnt if you touch it.

WARNING! Watch out for thrown objects.
Always wear eye protection. Never lean over

!

the cutting attachment guard. Stones,
rubbish, etc. can be thrown up into the eyes
causing blindness or serious injury.

Keep unauthorised persons at a distance.
Children, animals, onlookers and helpers
should be kept outside the safety zone of 15
m. Stop the machine immediately if anyone
approaches. Never swing the machine
around without first checking behind you to
make sure no-one is within the safety zone.

SAFETY INSTRUCTIONS

Grass trimming with a trimmer head

Trimming

• Hold the trimmer head just above the ground at an angle.
It is the end of the cord that does the work. Let the cord
work at its own pace. Never press the cord into the area to
be cut.

• The cord can easily remove grass and weeds up against
walls, fences, trees and borders, however it can also
damage sensitive bark on trees and bushes, and damage
fence posts.

• Reduce the risk of damaging plants by shortening the
cord to 10-12 cm and reducing the engine speed.

Clearing

Cutting

• The trimmer is ideal for cutting grass that is difficult to
reach using a normal lawn mower. Keep the cord parallel
to the ground when cutting. Avoid pressing the trimmer
head against the ground as this can ruin the lawn and
damage the tool.

• Do not allow the trimmer head to constantly come into
contact with the ground during normal cutting. Constant
contact of this type can cause damage and wear to the
trimmer head.

Sweeping

• The fan effect of the rotating cord can be used for quick
and easy clearing up. Hold the cord parallel to and above
the area to be swept and move the tool to and fro.

• The clearing technique removes all unwanted vegetation.
Keep the trimmer head just above the ground and tilt it. Let
the end of the cord strike the ground around trees, posts,
statues and the like. CAUTION! This technique increases
the wear on the cord.

• The cord wears quicker and must be fed forward more
often when working against stones, brick, concrete, metal
fences, etc., than when coming into contact with trees and
wooden fences.

• When trimming and clearing you should use less than full
throttle so that the cord lasts longer and to reduce the
wear on the trimmer head.

• When cutting and sweeping you should use full throttle to
obtain the best results.

WARNING! Neither the operator of the
machine nor anyone else may attempt to

!

remove the cut material while the engine is
running or the blade is rotating, as this can
result in serious injury.

Stop the engine and blade before you
remove material that has wound around the
blade shaft as otherwise there is a risk of
injury. The bevel gear can get hot during use
and may remain so for a while afterwards.
You could get burnt if you touch it.

WARNING! Watch out for thrown objects.
Always wear eye protection. Never lean over

!

the cutting attachment guard. Stones,
rubbish, etc. can be thrown up into the eyes
causing blindness or serious injury.

Keep unauthorised persons at a distance.
Children, animals, onlookers and helpers
should be kept outside the safety zone of 15
m. Stop the machine immediately if anyone
approaches.

FUEL HANDLING

Fuel

CAUTION! The machine 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.

WARNING! Always ensure there is adequate
ventilation when handling fuel.

!

Gasoline

CAUTION! Always use high grade unleaded oil mixed
gasoline (minimum 87 RON). If your machine is equipped with
a catalytic converter (see chapter on Technical data) always
use a good quality unleaded petrol/oil mixture. Leaded petrol
will destroy the catalytic converter and it will no longer serve
its purpose.

Use low-emission gasoline, also known as alkylate gasoline,
if it is available.

Mixing

• Always mix the gasoline and oil in a clean container
intended for fuel.

• Always start by filling half the amount of the gasoline to be
used. Then add the entire amount of oil. Mix (shake) the
fuel mixture. Add the remaining amount of gasoline.

• 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.

• If the machine is not used for some time the fuel tank
should be emptied and cleaned.

• This engine is certified to operate on unleaded

gasoline.

WARNING! The catalytic converter 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.

• This engine is certified to operate on unleaded
gasoline.

• 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 engine
temperature, which can result in a serious engine
breakdown.

• When working at continuous high revs a higher octane
rating is recommended.

Two-stroke oil

• For best results and performance use HUSQVARNA two­stroke oil, which is specially formulated for our two-stroke
engines. Mixture 1:50 (2%).

• Never use two-stroke oil intended for water-cooled
outboard engines, sometimes referred to as outboard oil.

• Never use oil intended for four-stroke engines.

Fuelling

WARNING! Taking the following precautions,
will lessen the risk of fire:

!

Do not smoke or place hot objects near fuel.

Always shut off the engine before refuelling.
Always stop the engine and let it cool for a
few minutes before refuelling.

When refuelling, open the fuel cap slowly so
that any excess pressure is released gently.
Tighten the fuel cap carefully after refuelling.
Always move the machine away from the
refuelling area before starting.

• Clean the area around the fuel cap. Contamination in the
tank can cause operating problems.

• Ensure that the fuel is well mixed by shaking the container
before filling the tank.

STARTING AND STOPPING

Check before starting

• Check the blade to ensure that no cracks have formed at
the bottom of the teeth or by the centre hole. The most
common reason why cracks are formed is that sharp
corners have been formed at the bottom of the teeth while
sharpening or that the blade has been used with dull
teeth. Discard a blade if cracks are found.

• Check that the support flange is not cracked due to fatigue
or due to being tightened too much. Discard the support
flange if it is cracked.

Starting and stopping

WARNING! The complete clutch cover and
shaft must be fitted before the machine is

!

started, otherwise the clutch can come loose
and cause personal injury.

Always move the machine away from the
refuelling area before starting. Place the
machine on a flat surface. Ensure the cutting
attachment cannot come into contact with
any object.

Make sure no unauthorised persons are in
the working area, otherwise there is a risk of
serious personal injury. The safety distance
is 15 metres.

Cold engine

Ignition: Set the stop switch to the start position.

Choke: Set the choke control in the choke position. This

should automatically set the stop switch to the start position.

• Ensure the locking nut has not lost its captive force. The
nut lock should have a locking force of at least 1.5 Nm. The
tightening torque of the locking nut should be 35-50 Nm.

• Check that the blade guard is not damaged or cracked.
Replace the blade guard if it is exposed to impact or is
cracked.

• Check that the trimmer head and trimmer guard are not
damaged or cracked. Replace the trimmer head or
trimmer guard if they have been exposed to impact or are
cracked.

Air purge: Press the air purge diaphragm repeatedly until fuel
begins to fill the diaphragm. The diaphragm need not be
completely filled.

Warm engine

Ignition: Set the stop switch to the start position.

Choke: Set the throttle to the start position by moving the

choke control to the choke position and then returning it to its
original position.

• Never use the machine without a guard nor with a
defective guard.

• All covers must be correctly fitted and undamaged before
you start the machine.

English – 19

STARTING AND STOPPING

Carburettor

Your Husqvarna product has been designed and
manufactured to specifications that reduce harmful
emissions. After the engine has used 8-10 tanks of fuel the
engine will be run-in. To ensure that it continues to run at peak
performance and to minimise harmful exhaust emissions after
the running-in period, ask your dealer/service workshop (who
will have a rev counter at their disposal) to adjust your
carburettor.

WARNING! The complete clutch cover and
shaft must be fitted before the machine is

!

started, otherwise the clutch can come loose
and cause personal injury.

Function

• The carburettor governs the engine’s speed via the
throttle control. Air and fuel are mixed in the carburettor.
The air/fuel mixture is adjustable. Correct adjustment is
essential to get the best performance from the machine.

• The setting of the carburettor means that the engine is
adepted to local conditions, for example, the climate,
altitude, fuel and the type of 2-stroke oil.

• The carburettor has three adjustment controls:

L = Low speed jet

H = High speed jet

T = Idle adjustment screw

CAUTION! If the cutting attachment rotates when the engine
is idling the idle adjustment screw T should be turned anti­clockwise until the cutting attachment stops.

Rec. idle speed 2700 rpm

Recommended max. speed: See the Technical data section.

WARNING! If the idle speed cannot be
adjusted so that the cutting attachment

!

stops, contact your dealer/service
workshop. Do not use the machine until it
has been correctly adjusted or repaired.

Fine adjustment

• When the machine has been ”run-in” the carburettor

should be finely adjusted. The fine adjustment should
be carried out by a qualified person. First adjust the L­jet, then the idling screw T and then the H-jet.

Conditions

• Before any adjustments are made, make sure that the air
filter is clean and the air filter cover is fitted. If you adjust
the carburettor when the air filter is dirty it will result in a
leaner mixture when the filter is finally cleaned. This can
lead to serious engine damage.

• Carefully turn both jets, L and H, so that they are midway
between fully screwed in and fully screwed out.

• Do not attempt to adjust the L and H jets beyond either
stop as this could cause damage.

• Now start the machine according to the starting
instructions and let it warm up for 10 minutes.

CAUTION! If the cutting attachment rotates when the
engine is idling the idle adjustment screw T should be
turned anti-clockwise until the cutting attachment stops.

• The L and H-jets are used to adjust the supply of fuel to
match the rate that air is admitted, which is controlled with
the throttle. If they are screwed clockwise the air/fuel ratio
becomes leaner (less fuel) and if they are turned anti­clockwise the ratio becomes richer (more fuel). A lean
mixture gives a higher engine speed and a rich mixture
gives a lower engine speed.

• The T-screw regulates the throttle setting at idle speed. If
the T-screw is turned clockwise this gives a higher idle
speed; turning it anti-clockwise gives a lower idle speed.

Basic setting

• The basic carburettor settings are adjusted during testing
at the factory. The basic setting is richer than the optimal
setting and should be maintained for the first few hours the
machine is in use. The carburettor should then be finely
adjusted. Fine adjustment should be carried out by a
skilled technician.

Low speed jet L

Try to find the highest idling speed, turning the low speed
needle L clockwise respectively counter-clockwise. When the
highest speed has been found, turn the low speed needle L 1/
4 turn counter-clockwise.

CAUTION! If the cutting attachment rotates when the engine
is idling the idle adjustment screw T should be turned anti­clockwise until the cutting attachment stops.

English – 21

MAINTENANCE

Fine adjustment of the idle speed T

Adjust the idle speed using the idle adjustment screw T, if it is
necessary to readjust. First turn the idle adjustment screw T
clockwise until the cutting attachment starts to rotate. Then
turn the screw anticlockwise until the cutting attachment
stops. The idle speed is correctly adjusted when the engine
will run smoothly in every position. The idle speed should also
be well below the speed at which the cutting attachment starts
to rotate.

WARNING! If the idle speed cannot be adjusted so that the
cutting attachment stops, contact your dealer/service
workshop. Do not use the machine until it has been correctly
adjusted or repaired.

High speed jet H

CAUTION! For optimum adjustment of the carburettor,

contact a qualified dealer/service workshop that has a
revolution counter at their disposal.

Correctly adjusted carburettor

When the carburettor is correctly adjusted the machine will
accelerate without hesitation and burble a little at maximum
speed. It is also important that the cutting attachment does
not rotate at idle. If the low speed jet L is set too lean it may
cause starting difficulties and poor acceleration.

If the high speed jet H is set too lean it will result in less power,
less performance, poor acceleration and/or damage to the
engine.

If both the L and H jets are set too rich it will results in
acceleration problems or too low a working speed.

Adjusting the start throttle speed

The correct start throttle speed is set by means of an adjuster
on the rear of the handle next to the cable. Use this screw (4
mm Allen screw) to increase or decrease the start throttle
speed.

The high speed jet H affects the engine power, speed,
temperature and fuel consumption. If the high speed jet H is
set too lean (screwed in too far) the engine speed will be too
high and cause engine damage. Do not let the engine run at
full speed for more than 10 seconds.

Apply full throttle and turn the high speed jet H very slowly
clockwise until the engine slows down. Then turn the high
speed jet H very slowly anticlockwise until the engine starts to
run unevenly. Now turn the high speed jet H slowly clockwise
a little way until the engine runs smoothly.

Note that the engine should not be under load when you
adjust the high speed jet H. You should therefore remove the
cutting attachment, nut, support flange and drive disc before
adjusting the high speed jet H.

The high speed jet H is adjusted correctly when the machine
burbles a little. If the machine races then the setting is too
lean. If the engine produces a lot of smoke and burbles a lot
then the setting is too rich.

Proceed as follows:

1 Run the machine at idle.

2 Press the start throttle lock as described under the

heading Starting and stopping.

3 If the start throttle speed is too low (below 4000 rpm), turn

the adjuster screw A clockwise until the cutting
attachment starts to rotate. Then turn A clockwise a
further 1/2 turn.

4 If the start throttle speed is too high, turn the adjuster

screw A anticlockwise until the cutting attachment stops.
Then turn adjuster screw A clockwise a further 1/2 turn.

WARNING! If the idle speed cannot be adjusted so that the
cutting attachment stops, contact your dealer/service
workshop. Do not use the machine until it has been correctly
adjusted or repaired.

Muffler

CAUTION! Some mufflers are fitted with a catalytic converter.

See chapter on Technical data to see whether your machine
is fitted with a catalytic converter.

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.

Some mufflers are equipped with a special spark arrestor
mesh. If your machine has this type of muffler, you should
clean the mesh at least once a week. This is best done with a
wire brush. On mufflers without a catalytic converter the mesh
should be cleaned weekly, or replaced if necessary. On
mufflers fitted with a catalytic converter the mesh should be
checked, and if necessary cleaned, monthly. If the mesh is

damaged it should be replaced.

If the mesh is frequently blocked, this can be a sign that the
performance of the catalytic converter is impaired. Contact
your dealer to inspect the muffler. A blocked mesh will cause
the machine to overheat and result in damage to the cylinder
and piston.

Cooling system

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

The cooling system consists of:

1 Air intake on the starter.

2 Fins on the flywheel.

3 Cooling fins on the cylinder.

4 Cylinder cover (directs 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 machine overheating which causes
damage to the piston and cylinder.

Bevel gear

The bevel gear is filled with the right quantity of grease at the
factory. However, before using the machine you should check
that the bevel gear is filled three-quarters full with grease. Use
HUSQVARNA special grease.

CAUTION! Never use a machine with a defective muffler.

WARNING! Mufflers fitted with catalytic
converters get very hot during use and

!

remain so for some time after stopping. This
also applies at idle speed. Contact can result
in burns to the skin. Remember the risk of
fire!

The grease in the bevel gear does not normally need to be
changed except if repairs are carried out.

English – 23

MAINTENANCE

Air filter

The air filter must be regularly cleaned to remove dust and dirt
in order to avoid:

• Carburettor malfunctions

• Starting problems

• Loss of engine power

• Unnecessary wear to engine parts

• Excessive fuel consumption.

Clean the filter every 25 hours, or more regularly if conditions
are exceptionally dusty.

Cleaning the air filter

Spark plug

The spark plug condition is influenced by:

• Incorrect carburettor adjustment.

• An incorrect fuel mixture (too much or incorrect type of
oil).

• A dirty air filter.

These factors cause deposits on the spark plug electrodes,
which may result in operating problems and starting
difficulties.

If the machine is low on power, difficult to start or runs poorly
at idle speed: always check the spark plug first before taking
any further action. If the spark plug is dirty, clean it and check
that the electrode gap is 0.5 mm (0,020"). The spark plug
should be replaced after about a month in operation or earlier
if necessary.

Remove the air filter cover and take out the filter. Wash it clean
in warm, soapy water. Ensure that the filter is dry before
refitting it.

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.

If the machine is used in dusty conditions the air filter should
be soaked in oil. See instructions under the heading Oiling the
air filter.

Oiling the air filter

Always use HUSQVARNA filter oil, art. no. 531 00 92-48. The
filter oil contains a solvent to make it spread evenly through
the filter. You should therefore avoid skin contact.

Put the filter in a plastic bag and pour the filter oil over it.
Knead the plastic bag to distribute the oil. Squeeze the
excess oil out of the filter inside the plastic bag and pour off
the excess before fitting the filter to the machine. Never use
common engine oil. This would drain through the filter quite
quickly and collect in the bottom.

CAUTION! Always use the recommended spark plug type!
Use of the wrong spark plug can damage the piston/cylinder.

Sharpening grass cutters and grass blades

WARNING! Always stop the engine before
doing any work on the cutting attachment.

!

This continues to rotate even after the
throttle has been released. Ensure that the
cutting attachment has stopped completely
and disconnect the HT lead from the spark
plug before you start to work on it.

• See the cutting attachment packaging for correct
sharpening instructions.

• Sharpen blades and cutters using a single-cut flat file.

• Sharpen all edges equally to maintain the balance of the
blade.

24 – English

WARNING! Always discard a blade that is
bent, twisted, cracked, broken or damaged

!

in any other way. Never attempt to straighten
a twisted blade so that it can be reused. Only
use original blades of the specified type.

MAINTENANCE

Filing the saw blade

WARNING! Using an incorrect cutting
attachment or an incorrectly sharpened

!

blade increases the risk of kickback.

• See the cutting attachment packaging for correct
sharpening instructions.

• A correctly filed blade is essential for working efficiently
and to avoid unnecessary wear to the blade and clearing
saw.

• Make sure that the blade is well supported when you file
it. Use a 5.5 mm round file with a file holder.

• The filing angle is 15°. File alternate teeth to the right and
those in between to the left. If the blade has been heavily
pitted by stones it may be necessary to dress the top
edges of the teeth with a flat file, in exceptional cases. If
so, this should be done before filing with a round file. The
top edges must be filed down by the same amount for all
the teeth.

• Clean the outside of the machine.

• Check that the harness is not damaged.

• Check that the hand guard is not damaged. Replace the
guard if damaged.

• Check that the trimmer is properly centered, sharp, and
without cracks.

• Check that the trimmer head is undamaged and not
cracked. Replace the trimmer head if necessary.

• A non-balanced blade/trimmer head induces heavy
vibrations that may damage the machine.

• Check that the blade nut is sufficiently tightened.

• Check that the transport guard for the blade is intact and
that it can be secured correctly.

• Check that nuts and screws are tight.

• Check that there are no fuel leaks from the engine, tank or
fuel lines.

Weekly maintenance

• Check the starter, the starter cord and the recoil spring.

• Clean the carburettor area.

• Clean the outside of the spark plug. Remove it and check
the electrode gap. Adjust the gap to 0.5 mm (.20”), or
replace the spark plug. Check that the spark plug is fitted
with a suppressor.

• Clean the cooling fins on the cylinder and check that the
air intake near the starter is not blocked.

• Check that the bevel gear is filled with grease up to 3/4.
Use special grease.

• Clean the air filter.

• Adjust the blade setting. This should be 1 mm.

Note: Use only HUSQVARNA replacement parts. Use of
other brands of replacement parts can cause damage to
your unit or injury to the operator or others. Your warranty
does not cover damage or liability caused by the use of
accessories and/or attachments not specifically
recommended by HUSQVARNA.
