ODUCTION

Dear customer!

Cong

ratulations 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.

Personal protective equipment

HELMET

A helmet should be w

orn if the trees being cleared are

taller than 2 m.

HEARING PROTECTION

Wear hearing protection that provides adequate noise

reduction.

IMPORTANT!

The machine is only designed for trimming grass, grass

clearing and/or forestry clearing.

The only accessories you can operate with this engine

unit are the cutting attachments we recommend in the

chapter on Technical data.

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.

Therefore remove the spark plug cap

when the machine is not under close

supervision.

IMPOR

TANT!

A clearing saw, brushcutter or trimmer can be

dangerous if used incorrectly or carelessly, and can

cause serious or fatal injury to the operator or others. It

is extremely important that you read and understand the

contents of this operator’s manual.

You must use approved personal protective equipment

whenever you use the machine. Personal protective

equipment cannot eliminate the risk of injury but it will

reduce the degree of injury if an accident does happen.

This section descr

ibes 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.

Thr

ottle lockout

The throttle loc

kout 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.

Make sure the throttle control is locked at the idle setting

when the throttle lockout is released.

Press the throttle lockout and make sure it returns to its

original position when you release it.

IMPOR

TANT! 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.

ARNING! 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.

GENERAL SAFETY PRECA

Chec

k that the throttle control and throttle lockout move

freely and that the return springs work properly.

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.

Stop s

witch

Use the stop s

witch to switch off the engine.

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.

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.

Vibration damping system

Your machine is equipped with a vibration damping

system that is designed to reduce vibration and make

operation easier.

Using incorrectly wound cord or a blunt or incorrect

cutting attachment (wrong type or incorrectly ﬁled, see

instructions under the heading Filing the blade) increases

the level of vibration.

The machine′s vibration damping system reduces the

transfer of vibration between the engine unit/cutting

equipment and the machine′s handle unit.

Regularly check the vibration damping units for cracks or

deformation. Check that the vibration damping element is

undamaged and securely attached.

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

English – 9

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 brush

cutter.

Check that the harness straps are correctly positioned.

Once the harness and machine have been adjusted,

check that the harness quick release works correctly.

Mufﬂer

The mufﬂer is designed to keep noise levels to a minimum

and to direct exhaust fumes away from the user. A mufﬂer

ﬁtted with a catalytic converter is also designed to reduce

harmful exhaust gases.

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.

Never use a machine that has a faulty mufﬂer.

Regularly check that the mufﬂer is securely attached to

the machine.

If the mufﬂer on your machine is ﬁtted with a spark

arrestor 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!

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!

GENERAL SAFETY PRECAUTIONS

Locking nut

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.) Tighten the nut using the socket spanner.

When loosening and tightening the saw blade nut, there

is a risk of injury from the teeth of the saw blade. You

should therefore always ensure that your hand is shielded

by the blade guard when doing this. Always use a socket

spanner with a shaft that is long enough to allow this. The

arrow in the diagram shows the area where you should

operate the socket spanner when loosening or tightening

the nut.

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

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

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

after it has been put on approx. 10 times.

Cutting equipment

This section describes how to choose and maintain your

cutting equipment in order to:

• Reduce the risk of blade thrust.

• Obtain maximum cutting performance.

• Extend the life of cutting equipment.

Cutting equipment

Saw blades are intended for cutting ﬁbrous types of wood.

Grass blades and grass cutters are intended for cutting

coarse grass.

A trimmer head is intended for trimming grass.

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.

Keep the teeth of the blade correctly sharpened! Follow

our recommendations. Also refer to the instructions on

the blade packaging.

Maintain the correct blade setting! Follow our

instructions and use the recommended ﬁle gauge.

WARNING! Always stop the engine

before doing any work on the cutting

attachment.This continues to rotate even

after the throttle has been released.

Ensure that the cutting attachment has

stopped completely and disconnect the

HT lead from the spark plug before you

start to work on it.

WARNING! Using an incorrect cutting

attachment or an incorrectly sharpened

blade increases the risk of blade thrust.
