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 Husqvarna River, for production of muskets. The
location was logical, since water power was harnessed from the Huskvarna River to create the water-powered plant. During the
more than 300 years of beeing, the Husqvarna factory has produced a lot of different products, from wood stoves to modern kitchen
appliances, sewing machines, bicycles, motorcycles etc. In 1956, the first motor driven lawn mowers appeared, followed by chain
saws in 1959, and it is within this area Husqvarna is working today.
Today Husqvarna is one of the leading manufacturers in the world of forest and garden products, with quality as our highest priority.
The business concept is to develop, manufacture and market motor driven products for forestry and gardening as well as for
building and construction industry. Husqvarna′s aim is also to be in the front edge according to ergonomics, usability, security and
environmental protection. That is the reason why we have developed many different features to provide our products within these
areas.
We are convinced that you will appreciate with great satisfaction the quality and performance of our product for a very long time to
come. The purchase of one of our products 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 authorised dealers, ask for the address of your nearest service
workshop.
It is our wish that you will be satisfied with your product and that it will be your companion for a long time. Think of this operator′s
manual as a valuable document. By following its′ content (using, service, maintenance etc) the life span and the second-hand value
of the machine can be extended. If you will sell this machine, make sure that the buyer will get the operator′s manual.
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
Important
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
are the cutting attachments we recommend in the chapter
on Technical data.

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.

Never use the machine if you are tired, if you have drunk
alcohol, or if you are taking medication that could affect your
vision, your judgement or your co-ordination.

HEARING PROTECTION

Wear personal protective equipment. See instructions
under the heading Personal protective equipment.

Wear hearing protection that provides adequate noise
reduction.

Never use a machine that has been modified in any way
from its original specification.
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.
All covers, guards and handles must be fitted before
starting. Ensure that the spark plug cap and ignition lead
are undamaged to avoid the risk of 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! The ignition system of this
machine produces an electromagnetic field
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.

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.

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

BOOTS
Wear boots with steel toe-caps and non-slip sole.

WARNING! Running an engine in a confined
or badly ventilated area can result in death
due to asphyxiation or carbon monoxide
poisoning.

Personal protective equipment
IMPORTANT!
A clearing saw, brushcutter or trimmer can be dangerous if
used incorrectly or carelessly, and can cause serious or
fatal injury to the operator or others. It is extremely
important that you read and understand the contents of this
operator’s manual.
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.

6 – English

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.
FIRST AID KIT
Always have a first aid kit nearby.

GENERAL SAFETY PRECAUTIONS
Machine′s safety equipment

Press the throttle lockout and make sure it returns to its
original position when you release it.

This section describes the machine′s safety equipment, its
purpose, and how checks and maintenance should be carried
out to ensure that it operates correctly. See the ”What is
what?” section to locate where this equipment is positioned
on your machine.
The life span of the machine can be reduced and the risk of
accidents can increase if machine maintenance is not carried
out correctly and if service and/or repairs are not carried out
professionally. If you need further information please contact
your nearest service workshop.
IMPORTANT!

Check that the throttle control and throttle lockout move freely
and that the return springs work properly.

All servicing and repair work on the machine requires
special training. This is especially true of the machine′s
safety equipment. If your machine fails any of the checks
described below you must contact your service agent.
When you buy any of our products we guarantee the
availability of professional repairs and service. If the retailer
who sells your machine is not a servicing dealer, ask him for
the address of your nearest service agent.

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.

See instructions under the heading Start. Start the machine
and apply full throttle. Release the throttle and check that the
cutting attachment stops and remains at a standstill. If the
cutting attachment rotates with the throttle in the idle position
then the carburettor idle setting must be checked. See
instructions under the heading Maintenance.

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
movement is controlled by two independent return springs.
This arrangement means that the throttle control is
automatically locked at the idle setting.

Stop switch
Use the stop switch to switch off the engine.

Make sure the throttle control is locked at the idle setting
when the throttle lockout is released.
Start the engine and make sure the engine stops when you
move the stop switch to the stop setting.

GENERAL SAFETY PRECAUTIONS
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.

Check that the guard is undamaged and not cracked. Replace
the guard if it has been exposed to impact or is cracked.
Always use the recommended guard for the cutting
attachment you are using. See chapter on Technical data.

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.

Regularly check the vibration damping units for cracks or
deformation. Check that the vibration damping element is
undamaged and securely attached.

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. Certain harnesses
also have a quick release fitted to the support hook.

Vibration damping system

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

Check that the harness straps are correctly positioned. Once
the harness and machine have been adjusted, check that the
harness quick release works correctly.

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.
Use of incorrectly wound cord or an incorrect cutting
attachment increases the level of vibration. See instructions
under the heading Cutting equipment.
The machine′s vibration damping system reduces the transfer
of vibration between the engine unit/cutting equipment and
the machine′s handle unit.
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.

8 – English

GENERAL SAFETY PRECAUTIONS
Never use a machine that has a faulty muffler.

Locking nut

A locking nut is used to secure some types of cutting
attachment.
Regularly check that the muffler is securely attached to the
machine.

If the muffler on your machine 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.

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.

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.) When
loosening and tightening the saw blade nut, there is a risk of
injury from the teeth of the saw blade. You should therefore
always ensure that your hand is shielded by the blade guard
when doing this. Always use a socket spanner with a shaft
that is long enough to allow this. The arrow in the diagram
shows the area where you should operate the socket spanner
when loosening or tightening the nut.

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.

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

Reduce the risk of blade thrust.

•

Obtain maximum cutting performance.

•

Extend the life of cutting equipment.
IMPORTANT!
Only use cutting attachments with the guards we
recommend! See the chapter on Technical data.

WARNING! Bear in mind that:
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!

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! 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.

WARNING! Using an incorrect cutting
attachment or an incorrectly sharpened
blade increases the risk of blade thrust.

GENERAL SAFETY PRECAUTIONS
Cutting equipment
Saw blades are intended for cutting fibrous types of wood.

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

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.

A trimmer head is intended for trimming grass.

General rules

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

Sharpening the saw blade

•
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.

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.

See the cutting attachment packaging for correct
sharpening instructions.

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

Keep the correct setting on the saw blade! Follow our
instructions and use the recommended setting tool. An
incorrectly set saw blade increases the risk of jamming and
blade thrust, and damage to the saw blade.

Check the cutting attachment for damage or cracks. A
damaged cutting attachment should always be replaced.

10 – English

•

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

GENERAL SAFETY PRECAUTIONS
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.

•

Adjust the blade setting. This should be 1 mm.

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

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.

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.

Forestry clearing
Move the suspension ring on the machine forward or
backward. It is easier to avoid sawing into the ground if the
blade is balanced a few dm above the ground.

Grass clearing
Let the blade balance at a comfortable cutting height, i.e.
close to the ground.

Quick 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.

FUEL HANDLING
Fuel safety

Petrol

Never start the machine:
1

If you have spilt fuel on it. Wipe off the spillage and allow
remaining fuel to evaporate.

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.

If the machine is leaking fuel. Check regularly for leaks
from the fuel cap and fuel lines.

CAUTION! Always use a quality petrol/oil mixture at least 90
octane (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.
Use low-emission petrol, also known as alkylate petrol, if it is
available.

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 petrol station to find
out where to dispose of excess fuel.

•

Ensure the machine is cleaned and that a complete
service is carried out before long-term storage.

•

The lowest octane recommended is 90 (RON). If you run
the engine on a lower octane grade than 90 so-called
knocking can occur. This gives rise to a high engine
temperature, which can result in serious engine damage.

•

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

Two-stroke oil

•

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

•

For best results and performance use HUSQVARNA twostroke engine oil, which is specially formulated for our aircooled two-stroke engines.

•

In order to prevent unintentional starting of the engine, the
spark plug cap must always be removed during long-term
storage, if the machine is not under close supervision and
when performing all service measures.

•

Never use two-stroke oil intended for water-cooled
engines, sometimes referred to as outboard oil (rated
TCW).

•

Never use oil intended for four-stroke engines.

•

A poor oil quality and/or too high oil/fuel ratio may
jeopardise function and decrease the life time of catalytic
converters.

•

Mixing ratio

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

Fuel

1:50 (2%) with HUSQVARNA two-stroke oil.

CAUTION! The machine is equipped with a two-stroke
engine and must always been run using a mixture of petrol
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! Fuel and fuel fumes are highly
inflammable and can cause serious injury
when inhaled or allowed to come in contact
with the skin. For this reason observe
caution when handling fuel and make sure
there is adequate ventilation.

FUEL HANDLING
Fuelling

Mixing
•

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

•

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

•

Mix (shake) the fuel mixture thoroughly before filling the
machine’s fuel tank.

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.

•

Do not mix more than one month’s supply of fuel at a time.

•

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

•

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

•

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.

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.

English

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.

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.

•

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.

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.
•

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.

Primer bulb: Press the air purge repeatedly until fuel begins
to fill the bulb. The bulb 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.

20 – English

STARTING AND STOPPING
Primer bulb: Press the air purge repeatedly until fuel begins
to fill the bulb. The bulb need not be completely filled.

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.

Starting

Hold the body of the machine on the ground using your left
hand (CAUTION! Not with your foot!). Grip the starter handle,
slowly pull out the cord with your right hand until you feel
some resistance (the starter pawls grip), now quickly and
powerfully pull the cord.
Repeat pulling the cord until the engine starts. When the
engine starts. return choke control to run position and apply
full throttle; the throttle will automatically disengage from the
start setting.

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.

Stopping

Stop the engine by switching off the ignition.

WORKING TECHNIQUES
General working instructions

Keep a good balance and a firm foothold.

Always hold the machine with both hands. Hold the
machine on the right side of your body.

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.
8

Keep the cutting attachment below waist level.

Basic safety rules

Switch off the engine before moving to another area. Fit
the transport guard before carrying or transporting the
equipment any distance.

Look around you:

10 Never put the machine down with the engine running
unless you have it in clear sight.

•

To ensure that people, animals or other things cannot
affect your control of the machine.

The ABC of clearing

•

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.

•

Always use the correct equipment.

•

Make sure the equipment is well adjusted.

CAUTION! Do not use the machine unless you are able to
call for help in the event of an accident.

•

Follow the safety precautions.

•

Organise your work carefully.

Inspect the working area. Remove all loose objects, such
as stones, broken glass, nails, steel wire, string, etc. that
could be thrown out or become wrapped around the
cutting attachment.

•

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

•

Always use sharp blades.

•

Avoid stones.

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.

•

Control the felling direction (take advantage of the wind).

•
2

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.

WARNING! Neither the operator of the
machine nor anyone else may attempt to
remove the cut material while the engine is
running or the cutting equipment is rotating,
as this can result in serious injury.
Stop the engine and cutting equipment
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.

Take great care when cutting a tree that is in tension. A
tree that is in 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

WARNING! Watch out for thrown objects.
Always wear approved 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.

WORKING TECHNIQUES

WARNING! Sometimes branches or grass
get caught between the guard and cutting
attachment. Always stop the engine before
cleaning.

•

You should plan the strip so that you avoid going over
ditches or other obstacles on the ground. You should also
orient the strip to take advantage of wind conditions, so
that cleared stems fall in the cleared area of the stand.

Working methods

WARNING! Machines fitted with saw blades
or grass blades can be thrown violently to
the side when the blade comes into contact
with a fixed object. This is called blade
thrust. A blade thrust can be violent enough
to cause the machine and/or operator to be
propelled in any direction, and possibly lose
control of the machine. Blade thrust can
occur without warning if the machine snags,
stalls or binds. Blade thrust is more likely to
occur in areas where it is difficult to see the
material being cut.

Forestry clearing using a saw blade

•

The risk of blade thrust increases with increasing stem
size. You should therefore avoid cutting with the area of
the blade between 12 o'clock and 3 o'clock.

•

To fell to the left, the bottom of the tree should be pushed
to the right. Tilt the blade and bring it diagonally down to
the right, exerting firm pressure. At the same time push
the stem using the blade guard. Cut with the area of the
blade between 3 o’clock and 5 o’clock. Apply full throttle
before advancing the blade.

•

To fell to the right, the bottom of the tree should be pushed
to the left. Tilt the blade and bring it diagonally up to the
right. Cut with the area of the blade between 3 o’clock and
5 o’clock so that the direction of rotation of the blade
pushes the bottom of the tree to the left.

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, blade thrust can occur if you
attempt to cut thick stems with this area of
the blade.
•

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

•

Start at whichever end of the area is easiest, and clear an
open space from which to work.

•

Work systematically to and fro across the area, clearing a
width of around 4-5 m on each pass. This exploits the full
reach of the machine in both directions and gives the
operator a convenient and varied working area to work in.

•

Clear a strip around 75 m long. Move your fuel can as
work progresses.

•

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.

English

– 23

WORKING TECHNIQUES
•

To fell a tree forwards, the bottom of the tree should be
pulled backwards. Pull the blade backwards with a quick,
firm movement.

•

Large stems must be cut from two sides. First determine
which direction the stem will fall. Make the first cut on the
felling side. Then finish cutting the stem from the other
side. Adjust the cutting pressure to match the size of the
stem and the hardness of the wood. Small stems require
more pressure, while large stems require less pressure.

•

If the stems are tightly packed, adapt your walking pace to
suit.

•

If the blade jams in a stem, never jerk the machine free. If
you do this the blade, bevel gear, shaft or handlebar may
be damaged. Release the handles, grip the shaft with
both hands and gently pull the machine free.

Brush cutting with a saw blade

•

Thin stems and brush are mown down. Work with a
sawing movement, swinging sideways.

•

Try to cut several stems in a single sawing movement.

•

With groups of hardwood stems, first clear around the
group. Start by cutting the stems high up around the
outside of the group to avoid jamming. Then cut the stems
to the required height. Now try to reach in with the blade

24 – English

and cut from the centre of the group. If it is still difficult to
gain access, cut the stems high up and let them fall. This
will reduce the risk of jamming.

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:

•

Always work at full throttle.

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.

WORKING TECHNIQUES
Grass trimming with a 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.

•

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

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
•

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.

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.

MAINTENANCE
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.

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
•

Function

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 L-jet,
then the idling screw T and then the H-jet.

Conditions
•

•

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.
Adjusting the carburettor means that the engine is
adapted to local operating conditions, e.g. climate,
altitude, petrol and the type of 2-stroke oil.

•

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.

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 anti-clockwise until the cutting attachment stops.

Low speed jet L
Try to find the highest idle speed by turning the low speed jet
L clockwise then anti-clockwise. When the highest speed has
been found, turn the low speed jet L 1/4 turn anti-clockwise.
•

•

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.

26 – English

+ 1/4

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.

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

MAINTENANCE
will run smoothly in every position. The idle speed should also
be well below the speed at which the cutting attachment starts
to rotate.

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.

Muffler

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.

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.

High speed jet H
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.

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.

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.

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.

CAUTION! For optimum adjustment of the carburettor,
contact a qualified dealer/service workshop that has a
revolution counter at their disposal.

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.
CAUTION! Never use a machine with a defective muffler.

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.

MAINTENANCE
Cooling system

Air filter

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

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.

The cooling system consists of:
1

Air intake on the starter.

Fins on the flywheel.

Cooling fins on the cylinder.

Cylinder cover (directs cold air over the cylinder).

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

Cleaning the air filter

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.

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.

Bevel gear

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.

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.

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

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

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.

28 – English

MAINTENANCE
Spark plug

The spark plug condition is influenced by:
•

Incorrect carburettor adjustment.

•

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

A dirty air filter.

These factors cause deposits on the spark plug electrodes,
which may result in operating problems and starting
difficulties.
If the machine is low on power, difficult to start or runs poorly
at idle speed: always check the spark plug first before taking
any further action. If the spark plug is dirty, clean it and check
that the electrode gap is 0.5 mm. The spark plug should be
replaced after about a month in operation or earlier if
necessary.

CAUTION! 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.

trimmer head if necessary.

Check that the locking nut of the cutting equipment is tighten correctly.

Check that nuts and screws are tight.

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

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

Weekly
maintenance

Check the starter and starter cord.

Check that the vibration damping elements are not damaged.

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

Clean the machines cooling system.

Clean or replace the spark arrestor mesh on the muffler (only applies to
mufflers without a catalytic converter).

Clean the outside of the carburettor and the space around it.

Check that the bevel gear is filled three-quarters full with lubricant. Fill if
necessary using special grease.

Monthly
maintenance

Check the fuel filter from contamination and the fuel hose from cracks or
other defects. Replace if necessary.

Check all cables and connections.

Check the clutch, clutch springs and the clutch drum for wear. Replace if
necessary by an autorized service workshop.
