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

Check that the throttle control and throttle lockout move freely

and that the return springs work properly.

′

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.

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.

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.

WARNING! Never use a machine with faulty

as described in this section. If your machine

fails any of these checks contact your

service agent to get it repaired.

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.

Start the engine and make sure the engine stops when you

move the stop switch to the stop setting.

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.

Make sure the throttle control is locked at the idle setting

when the throttle lockout is released.

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.

Press the throttle lockout and make sure it returns to its

original position when you release it.

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

Vibration damping system

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.

Your machine is equipped with a vibration damping system

that is designed to reduce vibration and make operation

easier.

For mufﬂers it is very important that you follow the instructions

on checking, maintaining and servicing your machine.

Never use a machine that has a faulty mufﬂer.

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.

Regularly check that the mufﬂer is securely attached to the

machine.

Regularly check the vibration damping units for cracks or

deformation. Check that the vibration damping element is

undamaged and securely attached.

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! 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.

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!

Mufﬂer

WARNING! The inside of the mufﬂer contain

chemicals that may be carcinogenic. Avoid

contact with these elements in the event of a

damaged 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.

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!

GENERAL SAFETY PRECAUTIONS

Locking nut

Trimmer head

IMPORTANT!

Always ensure the trimmer cord is wound tightly and evenly

around the drum, otherwise the machine will generate

harmful vibration.

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.)

•

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.

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.

•

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.

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.

•

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.

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.

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 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! A faulty cutting attachment may

increase the risk of accidents.

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.

•

When working at continuous high revs a higher octane

rating is recommended.

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.

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

should be emptied and cleaned.

Engine oil

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

level can cause serious damage to the engine.

•

When storing and transporting fuel always use approved

containers intended for this purpose.

When the machine is new the engine oil should be changed

after the ﬁrst month or after 10 hours of operation.

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.

•

For the best result and function use HUSQVARNA engin

oil.

•

The transport guard must always be ﬁtted to the cutting

attachment when the machine is being transported or in

storage.

•

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.

•

Never use oil intended for two-stroke engines.

WARNING! Take care when handling fuel.

Bear in mind the risk of ﬁre, explosion and

inhaling fumes.

Oil level

The machine must be switched off and placed on a ﬂat

surface when you check the oil level.

Fuel

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.

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

of the oil reﬁll hole.

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.

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.

Keep the cutting attachment below waist level.

The engine must be switched off before moving.

Basic safety rules

Never put the machine down with the engine running

unless you have it in clear sight.

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.

•

Look around you:

To ensure that people, animals or other things cannot

affect your control of the machine.

•

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

contact with the cutting attachment or loose objects that

are thrown out by the cutting attachment.

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.

•

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

call for help in the event of an accident.

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.

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.

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.

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.

Basic working techniques

Always slow the engine to idle speed after each working

operation. Long periods at full throttle without any load on the

engine can lead to serious engine damage.

Keep a good balance and a ﬁrm foothold.

WARNING! Sometimes branches or grass

get caught between the guard and cutting

attachment. Always stop the engine before

cleaning.

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

Carburetor

Mufﬂer

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! 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.

Function

•

The carburetor governs the engine’s speed via the throttle

control. Air and fuel are mixed in the carburetor.

Setting the carburettor involves adapting the engine to suit

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

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.

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.

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.

CAUTION! Never use a machine with a defective mufﬂer.

WARNING! Mufﬂers ﬁtted with catalytic

converters get very hot during use and

remain so for some time after stopping.This

also applies at idle speed. Contact can result

in burns to the skin. Remember the risk of

ﬁre!

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.

MAINTENANCE

Cooling system

Two-piece shaft

To keep the working temperature as low as possible the

machine is equipped with a cooling system.

The drive shaft end in the lower shaft should be lubricated

with grease every 30 hours.There is a risk that the drive shaft

ends (splined coupling) on models with two-piece shafts will

seize if they are not lubricated regularly.

Air ﬁlter

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).

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

in order to avoid:

•

Carburettor malfunctions

Starting problems

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.

Loss of engine power

Unnecessary wear to engine parts

Excessive fuel consumption.

Spark plug

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

are exceptionally dusty.

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.

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.

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.

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.

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.

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.

English – 19

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

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.
