INTRODUCTION

Dear customer!

Congratulations on your choice to buy a Husqvarna product! Husqvarna is based on a tradition that dates back to 1689, when the

Swedish King Karl XI ordered the construction of a factory on the banks of the Huskvarna River, for production of muskets. The

location was logical, since water power was harnessed from the Huskvarna River to create the water-powered plant. During over

300 years of continuous operation, the Husqvarna factory has produced a lot of different products, from wood stoves to modern

kitchen appliances, sewing machines, bicycles, motorcycles etc. In 1956, the ﬁrst motor driven lawn mowers appeared, followed

by chain saws in 1959, and it is within this area Husqvarna is working today.

Today Husqvarna is one of the leading manufacturers in the world of forest and garden products, with quality as our highest priority.

We develop, manufacture and market high quality motor driven products for forestry and gardening as well as for building and

construction industry.

Your purchase gives you access to professional help with repairs and service whenever this may be necessary. If the retailer who

sells your machine is not one of our authorized dealers, ask for the address of your nearest servicing dealer.

It is our wish that you will be satisﬁed with your product and that it will be your companion for a long time. Think of this 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 ever lend or sell this machine, make sure that the borrower or buyer gets the operator′s

manual, so they will also know how to properly maintain and use it.

Thank you for using a Husqvarna product.

Husqvarna AB has a policy of continuous product development and therefore reserves the right to modify the design and

appearance of products without prior notice.

GENERAL SAFETY PRECAUTIONS

Important

Personal protective equipment

IMPORTANT!

The machine is only designed for trimming grass, grass

clearing and/or forestry clearing.

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.

The only accessories you can operate with this engine unit

are the cutting attachments we recommend in the chapter

on Technical data.

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.

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.

Wear personal protective equipment. See instructions

under the heading Personal protective equipment.

Never use a machine that has been modiﬁed in any way

from its original speciﬁcation.

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.

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.

HELMET

A helmet should be worn if the trees being cleared are taller

than 2 m.

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.

HEARING PROTECTION

Wear hearing protection that provides adequate noise

reduction.

WARNING! The ignition system of this

machine produces an electromagnetic ﬁeld

during operation.This ﬁeld may under some

EYE PROTECTION

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.

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.

WARNING! Running an engine in a conﬁned

or badly ventilated area can result in death

due to asphyxiation or carbon monoxide

poisoning.

GLOVES

Gloves should be worn when necessary, e.g., when ﬁtting

cutting attachments.

WARNING! Never allow children to use or be

in the vicinity of the machine. As the

machine is equipped with a spring-loaded

stop switch and can be started by low speed

and force on the starter handle, even small

children under some circumstances can

produce the force necessary to start the

machine.This can mean a risk of serious

personal injury.Therefore remove the spark

plug cap when the machine is not under

close supervision.

BOOTS

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

GENERAL SAFETY PRECAUTIONS

CLOTHING

Make sure the throttle control is locked at the idle setting

when the throttle lockout is released.

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.

Press the throttle lockout and make sure it returns to its

original position when you release it.

′

Machine s safety equipment

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.

Check that the throttle control and throttle lockout move freely

and that the return springs work properly.

The life span of the machine can be reduced and the risk of

accidents can increase if machine maintenance is not carried

out correctly and if service and/or repairs are not carried out

professionally. If you need further information please contact

your nearest servicing dealer.

IMPORTANT! 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.

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.

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.

Throttle lockout

Stop switch

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.

Use the stop switch to switch off the engine.

Start the engine and make sure the engine stops when you

move the stop switch to the stop setting.

GENERAL SAFETY PRECAUTIONS

Regularly check the vibration damping units for cracks or

deformation. Check that the vibration damping element is

undamaged and securely attached.

Cutting attachment guard

WARNING! Overexposure to vibration can

lead to circulatory damage or nerve damage

in people who have impaired circulation.

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.

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.

Check that the guard is undamaged and not cracked.Replace

the guard if it has been exposed to impact or is cracked.

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.

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.

Vibration damping system

Check that the harness straps are correctly positioned. Once

the harness and machine have been adjusted, check that the

harness quick release works correctly.

Your machine is equipped with a vibration damping system

that is designed to reduce vibration and make operation

easier.

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.

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.

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 screen. Check whether the mufﬂer on your

machine is ﬁtted with this kind of screen.

For mufﬂers it is very important that you follow the instructions

on checking, maintaining and servicing your machine.

8 – English

Download from Www.Somanuals.com. All Manuals Search And Download.

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.

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.

If the mufﬂer on your machine is ﬁtted with a spark arrestor

screen this must be cleaned regularly. A blocked screen 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!

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.

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:

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!

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.

GENERAL SAFETY PRECAUTIONS

General rules

Cutting equipment

This section describes how to choose and maintain your

cutting equipment in order to:

•

Reduce the risk of blade thrust.

Only use cutting attachments with the guards we

recommend! See the chapter on Technical data.

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.

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.

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.

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.

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.

Check the cutting attachment for damage or cracks. A

damaged cutting attachment should always be replaced.

WARNING! Using an incorrect cutting

attachment or an incorrectly sharpened

blade increases the risk of blade thrust.

Cutting equipment

Saw blades are intended for cutting ﬁbrous types of wood.

Sharpening grass cutters and grass

blades

Grass blades and grass cutters are intended for cutting

coarse grass.

•

See the cutting attachment packaging for correct

sharpening instructions. Sharpen blades and cutters

using a single-cut ﬂat ﬁle.

blade.

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.

Trimmer head

IMPORTANT!

Always ensure the trimmer cord is wound tightly and evenly

around the drum, otherwise the machine will generate

harmful vibration.

Sharpening the saw blade

•

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.

•

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.

•

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 blade is well supported when you ﬁle

it. Use a 5.5 mm round ﬁle with a ﬁle holder.

•

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.

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.

ASSEMBLY

Correct balance

Adjusting the harness and clearing

saw

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 suspension ring to balance the clearing saw

correctly.

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.

Standard harness

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.

Spreading the load on your shoulders

A well-adjusted harness and machine makes work much

easier. Adjust the harness for the best working position.

FUEL HANDLING

Gasoline

Fuel safety

Never start the machine:

If you have spilled fuel on it.Wipe off the spillage and allow

remaining fuel to evaporate.

CAUTION! Always use a quality gasoline/oil mixture with an

octane rating of at least 87 octane ((RON+MON)/2). If your

machine is equipped with a catalytic converter (see chapter

on Technical data) always use a good quality unleaded

gasoline/oil mixture.Leaded gasoline will destroy the catalytic

converter.

If you have spilled fuel on yourself or your clothes, change

your clothes.Wash any part of your body that has come in

contact with fuel. Use soap and water.

If the machine is leaking fuel. Check regularly for leaks

from the fuel cap and fuel lines.

Use low-emission gasoline, also known as alkylate gasoline,

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.

This engine is certiﬁed to operate on unleaded gasoline.

•

The lowest recommended octane grade is 87

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.

((RON+MON)/2). If you run the engine on a lower octane

grade than 87 so-called knocking can occur. This gives

rise to a high engine temperature and increased bearing

load, which can result in serious engine damage.

•

Ensure the machine is cleaned and that a complete

service is carried out before long-term storage.

•

When working at continuous high revs a higher octane

rating is recommended.

The transport guard must always be ﬁtted to the cutting

attachment when the machine is being transported or in

storage.

Two-stroke oil

•

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.

•

For best results and performance use HUSQVARNA two-

stroke engine oil, which is specially formulated for our air-

cooled two stroke-engines.

•

Never use two-stroke oil intended for water-cooled

engines, sometimes referred to as outboard oil (rated

TCW).

WARNING! Take care when handling fuel.

Bear in mind the risk of ﬁre, explosion and

inhaling fumes.

•

Never use oil intended for four-stroke engines.

Mixing ratio

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

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.

FUEL HANDLING

Mixing

Fueling

•

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.

WARNING!Taking the following precautions,

will lessen the risk of ﬁre:

•

Mix (shake) the fuel mixture thoroughly before ﬁlling the

machine’s fuel tank.

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.

•

Clean the area around the fuel cap. Contamination in the

tank can cause operating problems.

If the machine is not used for some time the fuel tank

should be emptied and cleaned.

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.

STARTING AND STOPPING

Check before starting

Starting and stopping

•

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.

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.

•

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

Primer bulb: Press the air purge repeatedly until fuel begins

to ﬁll the bulb. The bulb need not be completely ﬁlled.

•

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.

Choke: Set the choke control in the choke position.

•

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.

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.

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.Never wrap the starter cord around

your hand

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.

•

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.

STARTING AND STOPPING

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.

CAUTION! Do not put any part of your body in marked area.

Contact can result in burns to the skin, or electrical shock if

the spark plug cap has been damaged. Always use gloves.

Do not use a machine with damaged spark plug cap.

CAUTION! The stop switch automatically returns to the start

position. In order to prevent unintentional starting, the spark

plug cap must be removed from the spark plug when

assembling, checking and/or performing maintenance.

For throttle handles with a start throttle

lock:

Set the throttle to the start position by ﬁrst pressing the throttle

lockout and the throttle trigger, then pressing the start throttle

button (A). Then release the throttle lockout and the throttle

trigger, followed by the start throttle button. The throttle

function is now activated. To return the engine to idle, press

the throttle lockout and throttle trigger again.

PART THROTTLE FUNCTION (RX, RDX):

It is possible to set the engine for part throttle operation using

the dial on the side of the throttle handle. Turn the dial up to

decrease the part throttle rpm.Turn the dial down to increase

the part throttle rpm.When you have set the part throttle rpm

you will feel increased resistance when you press the throttle

trigger.This increased resistance makes it easier to maintain

a constant part throttle setting.To obtain full throttle, press the

throttle trigger a little harder so that it goes past the part

throttle setting. As soon as you release the throttle trigger the

engine will return to idle. The part throttle function does not

lock the engine at a given rpm, it is simply a brake that makes

it easier to maintain the engine at a given rpm.

WORKING TECHNIQUES

Keep a good balance and a ﬁrm foothold.

General working instructions

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.

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.

10 Never put the machine down with the engine running

unless you have it in clear sight.

•

Look around you:

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.

Follow the safety precautions.

•

CAUTION! Do not use the machine unless you are able to

call for help in the event of an accident.

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).

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.

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.

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.

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.

Take great care when cutting a tree that is under tension.

A tree that is under tension may spring back to its normal

position before or after being cut. If you position yourself

incorrectly or make the cut in the wrong place the tree may

hit you or the machine and cause you to lose control. Both

situations can cause serious personal injury.

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.

attachment. Always stop the engine before

cleaning.

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.

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.

•

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.

•

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.

•

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.

•

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.

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.

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.

•

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.

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 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.

•

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.

Brush cutting with a saw blade

•

Let the support cup rest lightly against the ground. It is

used to protect the blade from hitting the ground.

•

Thin stems and brush are mown down. Work with a

sawing movement, swinging sideways.

Reduce the risk of material wrapping around the blade by

following these instructions:

•

Try to cut several stems in a single sawing movement.

Always work at full throttle.

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

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

Sweeping

Grass trimming with a trimmer head

•

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.

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.

•

When cutting and sweeping you should use full throttle to

obtain the best results.

•

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

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.

Carburetor

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.

Rec. idle speed 2700 rpm

Recommended max. speed: See theTechnical 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.

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.

Fine adjustment

•

When the machine has been ”run-in” the carburetor

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.

Function

Conditions

•

The carburetor governs the engine’s speed via the throttle

control. Air and fuel are mixed in the carburetor. The air/

fuel mixture is adjustable. Correct adjustment is essential

to get the best performance from the machine.

•

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.

•

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.

•

Carefully turn both jets, L and H, so that they are midway

between fully screwed in and fully screwed out.

The carburetor has three adjustment controls:

L = Low speed jet

Do not attempt to adjust the L and H jets beyond either

stop as this could cause damage.

H = High speed jet

Now start the machine according to the starting

instructions and let it warm up for 10 minutes.

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 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.

•

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 anti-

clockwise the ratio becomes richer (more fuel). A lean

mixture gives a higher engine speed and a rich mixture

gives a lower engine speed.

+ 1/4

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.

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.

Basic setting

•

The basic carburetor 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.

Fine adjustment of the idle speedT

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.

Correctly adjusted carburetor

When the carburetor 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.

WARNING! If the idle speed cannot be

adjusted so that the cutting attachment

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.

stops, contact your dealer/service

workshop. Do not use the machine until it

has been correctly adjusted or repaired.

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.

Proceed as follows:

Run the machine at idle.

Press the start throttle lock as described under the

heading Starting and stopping.

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.

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.

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.

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.

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.

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.

CAUTION! For optimum adjustment of the carburettor,

contact a qualiﬁed dealer/service workshop that has a

revolution counter at their disposal.

MAINTENANCE

Mufﬂer

Cooling system

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.

To keep the working temperature as low as possible the

machine is equipped with a cooling system.

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.

The cooling system consists of:

Air intake on the starter.

Fins on the ﬂywheel.

Cooling ﬁns on the cylinder.

Cylinder cover (directs cold air over the cylinder).

Some mufﬂers are equipped with a special spark arrestor

screen. If your machine has this type of mufﬂer, you should

clean the screen at least once a week.This is best done with

a wire brush. On mufﬂers without a catalytic converter the

screen should be cleaned weekly, or replaced if necessary.

On mufﬂers ﬁtted with a catalytic converter the screen should

be checked, and if necessary cleaned, monthly. If the screen

is damaged it should be replaced. If the screen is

often in demanding conditions. A dirty or blocked cooling

system results in the machine overheating which causes

damage to the piston and cylinder.

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 screen will cause the machine

to overheat and result in damage to the cylinder and piston.

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.

The grease in the bevel gear does not normally need to be

changed except if repairs are carried out.

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!

MAINTENANCE

Air ﬁlter

Spark plug

The air ﬁlter must be regularly cleaned to remove dust and dirt

in order to avoid:

The spark plug condition is inﬂuenced by:

•

Incorrect carburetor adjustment.

•

Carburettor malfunctions

Starting problems

An incorrect fuel mixture (too much or incorrect type of

oil).

Loss of engine power

•

A dirty air ﬁlter.

Unnecessary wear to engine parts

Excessive fuel consumption.

These factors cause deposits on the spark plug electrodes,

which may result in operating problems and starting

difﬁculties.

If the machine is low on power, difﬁcult to start or runs poorly

at idle speed: always check the spark plug ﬁrst before taking

any further action. If the spark plug is dirty, clean it and check

that the electrode gap is 0.020 inch (0.5 mm).The spark plug

should be replaced after about a month in operation or earlier

if necessary.

Clean the ﬁlter every 25 hours, or more regularly if conditions

are exceptionally dusty.

Cleaning the air ﬁlter

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.

CAUTION! Always use the recommended spark plug type!

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.

Use of the wrong spark plug can damage the piston/cylinder.

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.

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.
