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.

sandals or go barefoot.Secure hair so it is above shoulder

level.

FIRST AID KIT

Always have a ﬁrst aid kit nearby.

Make sure the throttle control is locked at the idle setting

when the throttle lockout is released.

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.

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.

Press the throttle lockout and make sure it returns to its

original position when you release it.

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,

be checked. See instructions under the heading

Maintenance.

Vibration damping system

Your machine is equipped with a vibration damping

system that is designed to reduce vibration and make

operation easier.

Stop switch

Use of incorrectly wound cord or an incorrect cutting

attachment increases the level of vibration. See

instructions under the heading Cutting equipment.

Use the stop switch to switch off the engine.

The machine′s vibration damping system reduces the

transfer of vibration between the engine unit/cutting

equipment and the machine′s handle unit.

Start the engine and make sure the engine stops when

you move the stop switch to the stop setting.

Cutting attachment guard

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

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.

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.

Check that the guard is undamaged and not cracked.

Replace the guard if it has been exposed to impact or is

cracked.

Mufﬂer

Always use the recommended guard for the cutting

attachment you are using. See chapter on Technical data.

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.

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.

GENERAL SAFETY PRECAUTIONS

In countries that have a warm and dry climate there is a

WARNING! The inside of the mufﬂer

contain chemicals that may be

carcinogenic. Avoid contact with these

elements in the event of a damaged

mufﬂer.

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.

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!

For mufﬂers it is very important that you follow the

instructions on checking, maintaining and servicing your

machine.

Locking nut

Never use a machine that has a faulty mufﬂer.

A locking nut is used to secure some types of cutting

attachment.

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.)

Regularly check that the mufﬂer is securely attached to

the machine.

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.

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.

The nylon lining inside the locking nut must not be so worn

that you can turn it by hand. The lining should offer a

resistance of at least 1.5 Nm.The nut should be replaced

after it has been put on approx. 10 times.

WARNING! 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!

GENERAL SAFETY PRECAUTIONS

Trimmer head

Cutting equipment

This section describes how to choose and maintain your

cutting equipment in order to:

IMPORTANT!

Always ensure the trimmer cord is wound tightly and

evenly around the drum, otherwise the machine will

generate harmful vibration.

•

Reduce the risk of blade thrust.

Obtain maximum cutting performance.

Extend the life of cutting equipment.

•

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.

IMPORTANT!

Only use cutting attachments with the guards we

recommend! See the chapter on Technical data.

Refer to the instructions for the cutting attachment to

check the correct way to load the cord and the correct

cord diameter.

WARNING! Always stop the engine

before doing any work on the cutting

•

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.

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.

The length of the cord is also important. A longer cord

requires greater engine power than a shorter cord of

the same diameter.

WARNING! A faulty cutting attachment

may increase the risk of accidents.

•

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.

FUEL HANDLING

Gasoline

Fuel handling

Always use an unleaded quality petrol of at least 90

octane (RON).

Never start the machine:

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

allow remaining fuel to evaporate.

Use low-emission gasoline, also known as alkylate

gasoline, if it is available.

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.

•

The lowest recommended octane grade is 87

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

octane grade than 87 so-called knocking can occur.

This gives rise to a high engine temperature and

increased bearing load, which can result in serious

engine damage.

If the machine is leaking fuel. Check regularly for

leaks from the fuel cap and fuel lines.

Transport and storage

•

When working at continuous high revs a higher octane

rating is recommended.

•

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.

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

should be emptied and cleaned.

Engine oil

•

When storing and transporting fuel always use

approved containers intended for this purpose.

Check the oil level before starting the machine. A too low

oil level can cause serious damage to the engine.

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.

When the machine is new the engine oil should be

changed after the ﬁrst month or after 10 hours of

operation.

•

The transport guard must always be ﬁtted to the

cutting attachment when the machine is being

transported or in storage.

•

For the best result and function use HUSQVARNA

engin oil.

•

When HUSQVARNA engine oil is not available

another high grade engine oil can be used. Contact

your dealer when selecting oil. Engine oil for four-

stroke petrol engines must be used. Quality class at

least API SG. In general viscosity class SAE 10W-40

is recommended.

Ensure the machine is cleaned and that a complete

service is carried out before long-term storage.

WARNING!Take care when handling fuel.

Bear in mind the risk of ﬁre, explosion

and inhaling fumes.

•

Never use oil intended for two-stroke engines.

Fuel

Oil level

The machine must be switched off and placed on a ﬂat

surface when you check the oil level.

Unscrew the oil cap, clean the dipstick located on the cap

and insert the cap again without screwing it down. Check

the oil level on the dipstick.

CAUTION! The machine is equipped with a four-stroke

engine. Make sure that there is always sufﬁcient oil in the

oil tank.

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.

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.

FUEL HANDLING

When the oil level is low, top up using engine oil to the

edge of the oil reﬁll hole.

Only use recommended engine oil.

Fueling

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.

General working instructions

IMPORTANT!

This section takes up the basic safety precautions for

working with a trimmer.

If you encounter a situation where you are uncertain

how to proceed you should ask an expert. Contact your

dealer or your service workshop.

Avoid all usage which you consider to be beyond your

capability.

You must understand the difference between forestry

clearing, grass clearing and grass trimming before use.

Basic safety rules

Keep the cutting attachment below waist level.

The engine must be switched off before moving.

•

Look around you:

To ensure that people, animals or other things cannot

affect your control of the machine.

Never put the machine down with the engine running

unless you have it in clear sight.

•

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.

WARNING! Neither the operator of the

machine nor anyone else may attempt to

•

CAUTION! Do not use the machine unless you are

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

remove the cut material while the engine

is running or the cutting equipment is

rotating, as this can result in serious

injury.

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.

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.

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.

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! 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

Cutting

Basic working techniques

•

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.

Always slow the engine to idle speed after each working

operation. Long periods at full throttle without any load on

the engine can lead to serious engine damage.

WARNING! Sometimes branches or

grass get caught between the guard and

cutting attachment. Always stop the

engine before cleaning.

Grass trimming with a trimmer head

•

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.

Trimming

Sweeping

• The fan effect of the rotating cord can be used for

•

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.

quick and easy clearing up. Hold the cord parallel to

and above the area to be swept and move the tool to

and fro.

•

The 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.

•

When cutting and sweeping you should use full

throttle to obtain the best results.

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.

MAINTENANCE

Mufﬂer

Carburetor

Function

•

The carburetor governs the engine’s speed via the

throttle control. Air and fuel are mixed in the

carburetor.

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.

•

Setting the carburettor involves adapting the engine to

suit local conditions, e.g. climate, altitude and the

petrol.

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.

Basic setting

The basic carburetor settings are adjusted during testing

at the factory.

CAUTION! For optimum adjustment of the carburettor,

contact a qualiﬁed dealer/service workshop that has a

revolution counter at their disposal.

Adjusting the idle speed (T)

Check that the air ﬁlter is clean. When the idle speed is

correct, the cutting attachment should not rotate. If

adjustment is required, close (turn clockwise) the idle

adjustment screw T, with the engine running, until the

cutting attachment starts to rotate. Open (turn

anticlockwise) the screw until the cutting attachment

stops. The idle speed is correctly set when the engine

runs smoothly in all positions, and there is a clear margin

to the speed at which the cutting attachment starts to

rotate.

The mufﬂer on your machine is equipped with a spark

arrestor screen, this should be cleaned regularly. A

blocked screen will cause the engine to overheat and may

lead to serious damage.

CAUTION! Never use a machine with a defective 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.

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

Cooling system

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.

Clean the ﬁlter every 25 hours, or more regularly if

conditions are exceptionally dusty.

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).

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.

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.

Spark plug

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 spark plug condition is inﬂuenced by:

•

Incorrect carburetor adjustment.

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 used in dusty conditions the air ﬁlter

should be soaked in oil. See instructions under the

heading Oiling the air ﬁlter.

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 0,6-0,7 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.

MAINTENANCE

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.

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.

The grease in the bevel gear does not normally need to

be changed except if repairs are carried out.

IMPORTANT! 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.
