INTR

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 Husqvarna River, for production

of muskets. The location was logical, since water power was harnessed from the Huskvarna River to create the water-

powered plant. During the more than 300 years in existence, the Husqvarna factory has produced a lot of different

products, from wood stoves to modern kitchen appliances, sewing machines, bicycles, motorcycles etc. In 1956, the ﬁrst

motor driven lawn mowers appeared, followed by chain saws in 1959, and it is within this area Husqvarna is working

today.

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

highest priority. The business concept is to develop, manufacture and market motor-driven products for forestry and

gardening, as well as for the building and construction industry. Husqvarna

′

s aim is also to be at the front edge for

ergonomics, usability, security and environmental protection. That is the reason why we have developed many different

features to add to our products within these areas.

We are convinced that you will appreciate with great satisfaction the quality and performance of our product for a very

long time to come. The purchase of one of our products gives you access to professional help with repairs and service

whenever this may be necessary. If the retailer who sells your machine is not one of our authorised dealers, ask for the

address of your nearest service workshop.

It is our wish that you will be satisﬁed with your product and that it will be your companion for a long time. Think of this

operator

′

s manual as a valuable document. By following its content (usage, service, maintenance, etc), the life span and

the second-hand value of the machine can be extended. If you sell this machine, make sure that the operator

′

s manual

is passed on to the buyer.

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

10 – English

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 knifes are intended for cutting

coarse grass.

A trimmer head is intended for trimming grass.

General rules

Only use cutting attachments with the guards we

recommend! See the chapter on Technical data.

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.

Keep the correct setting on the saw blade! Follow our

instructions and use the recommended setting tool. An

incorrectly set saw blade increases the risk of jamming

and blade thrust, and damage to the saw blade.

Check the cutting attachment for damage or cracks. A

damaged cutting attachment should always be replaced.

Sharpening grass knifes and grass

blades

• See the cutting attachment packaging for correct

sharpening instructions. Sharpen blades and knifes

using a single-cut ﬂat ﬁle.

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

spark plug cap before you start to work

on it.

!

WARNING! Using an incorrect cutting

attachment or an incorrectly sharpened

blade increases the risk of blade thrust.

H1158111-38,543RS,GB.fm Page 10 Monday, January 11, 2016 1:47 PM

GENERAL SAFETY PRECAUTIONS

English – 11

• Sharpen all edges equally to maintain the balance of

the blade.

Sharpening the saw blade

• 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

brush cutter.

• Make sure that the blade is well supported when you

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

• The ﬁling angle is 15°. File alternate teeth to the right

and those in between to the left. If the blade has been

heavily pitted by stones it may be necessary to dress

the top edges of the teeth with a ﬂat ﬁle, in exceptional

cases. If so, this should be done before ﬁling with a

round ﬁle. The top edges must be ﬁled down by the

same amount for all the teeth.

• Adjust the blade setting. This should be 1 mm.

Trimmer head

• Only use the recommended trimmer heads and

trimmer cords. These have been tested by the

manufacturer to suit a particular engine size. This is

especially important when a fully automatic trimmer

head is used. Only use the recommended cutting

attachment. See the chapter on Technical data.

• Smaller machines generally require small trimmer

heads and vice versa. This is because when clearing

using a cord the engine must throw out the cord

radially from the trimmer head and overcome the

resistance of the grass being cleared.

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

requires greater engine power than a shorter cord of

the same diameter.

• Make sure that the cutter on the trimmer guard is

intact. This is used to cut the cord to the correct length.

• To increase the life of the cord it can be soaked in

water for a couple of days before use. This will make

the cord tougher so that it lasts longer.

!

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.

IMPORTANT!

Always ensure the trimmer cord is wound tightly and

evenly around the drum, otherwise the machine will

generate harmful vibration.

FUEL HANDLING

14 – English

Fuel safety

Never start the machine:

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

allow remaining fuel to evaporate.

2 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.

3 If the machine is leaking fuel. Check regularly for

leaks from the fuel cap and fuel lines.

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 open ﬂames, for example, from

electrical machinery, electric motors, electrical relays/

switches or boilers.

• When storing and transporting fuel always use

approved containers intended for this purpose.

• When storing the machine for long periods the fuel

tank must be emptied. Contact your local petrol

station to ﬁnd out where to dispose of excess fuel.

• Ensure the machine is cleaned and that a complete

service is carried out before long-term storage.

• The transport guard must always be ﬁtted to the

cutting attachment when the machine is being

transported or in storage.

• Secure the machine during transport.

• 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.

Fuel

CAUTION! The machine is equipped with a two-stroke

engine and must always be run using a mixture of petrol

and two-stroke 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.

Petrol

CAUTION! Always use a quality petrol/oil mixture at least

90 octane (RON). If your machine is equipped with a

catalytic converter (see chapter on Technical data) always

use a good quality unleaded petrol/oil mixture. Leaded

petrol will destroy the catalytic converter.

Use low-emission petrol, also known as alkylate petrol, if

it is available.

• The lowest octane recommended is 90 (RON). If you

run the engine on a lower octane grade than 90 so-

called knocking can occur. This gives rise to a high

engine temperature, which can result in serious

engine damage.

• When working at continuous high revs a higher octane

rating is recommended.

Two-stroke oil

• 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).

• Never use oil intended for four-stroke engines.

• A poor oil quality and/or too high oil/fuel ratio may

jeopardise function and decrease the life time of

catalytic converters.

• Mixing ratio

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

1:33 (3%) with oils class JASO FB or ISO EGB

formulated for air-cooled, two-stroke engines.

!

WARNING! Take care when handling fuel.

Bear in mind the risk of ﬁre, explosion

and inhaling fumes.

!

WARNING! Fuel and fuel fumes are

highly inﬂammable and can cause

serious injury when inhaled or allowed to

come in contact with the skin. For this

reason observe caution when handling

fuel and make sure there is adequate

ventilation.

FUEL HANDLING

English – 15

Mixing

• Always mix the petrol and oil in a clean container

intended for fuel.

• Always start by ﬁlling half the amount of the petrol to

be used. Then add the entire amount of oil. Mix

(shake) the fuel mixture. Add the remaining amount of

petrol.

• Mix (shake) the fuel mixture thoroughly before ﬁlling

the machine’s fuel tank.

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

time.

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

should be emptied and cleaned.

Fueling

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

• Clean the area around the fuel cap. Contamination in

the tank can cause operating problems.

• Ensure that the fuel is well mixed by shaking the

container before ﬁlling the tank.

!

WARNING! 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

STARTING AND STOPPING

16 – English

Check before starting

• Check the blade to ensure that no cracks have formed

at the bottom of the teeth or by the centre hole. The

most common reason why cracks are formed is that

sharp corners have been formed at the bottom of the

teeth while sharpening or that the blade has been

used with dull teeth. Discard a blade if cracks are

found.

• 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.

• Ensure the locking nut has not lost its captive force.

The nut lock should have a locking force of at least 1.5

Nm. The tightening torque of the locking nut should be

35-50 Nm.

• Check that the blade guard is not damaged or

cracked. Replace the blade guard if it is exposed to

impact or is cracked.

• Check that the trimmer head and trimmer guard are

not damaged or cracked. Replace the trimmer head or

trimmer guard if they have been exposed to impact or

are cracked.

• 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

Primer bulb: Press the air purge repeatedly until fuel

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

ﬁlled.

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 twist 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.

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.

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.

Throttle settings control

Move the throttle to the idle position.

Stopping

Stop the engine by switching off the ignition.

CAUTION! Stop the engine by switching off the ignition.

General working instructions

Basic safety rules

1 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.

• CAUTION! Do not use the machine unless you are

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

2 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.

3 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.

4 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.

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

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

position before or after being cut. If you position

yourself incorrectly or make the cut in the wrong place

the tree may hit you or the machine and cause you to

lose control. Both situations can cause serious

personal injury.

6 Keep a good balance and a ﬁrm foothold. Do not

overreach. Keep proper footing and balance at all

times.

7 Always hold the machine with both hands. Hold the

machine on the right side of your body. Keep all parts

of your body away from the hot surfaces. Keep all

parts of your body away from the rotating cutting

attachment.

8 When using a brush cutter it must always be hooked

securely to the harness. Otherwise you will be unable

to control the brush cutter safely and this can result in

injury to yourself or others. Never use a harness with

a defective quick release.

9 Keep the cutting attachment below waist level.

10 Switch off the engine before moving to another area.

Fit the transport guard before carrying or transporting

the equipment any distance.

11 Never put the machine down with the engine running

unless you have it in clear sight.

IMPORTANT!

This section describes the basic safety precautions for

working with brush cutters 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.

Working methods

• Before you start clearing, check the clearing area, the

type of terrain, the slope of the ground, whether there

are stones, hollows etc.

• Start at whichever end of the area is easiest, and clear

an open space from which to work.

• Work systematically to and fro across the area,

clearing a width of around 4-5 m on each pass. This

exploits the full reach of the machine in both directions

and gives the operator a convenient and varied

working area to work in.

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

work progresses.

• On sloping ground you should work along the slope. It

is much easier to work along a slope than it is to work

up and down it.

• You should plan the strip so that you avoid going over

ditches or other obstacles on the ground. You should

also orient the strip to take advantage of wind

!

WARNING! Neither the operator of the

machine nor anyone else may attempt to

remove the cut material while the engine

is running or the cutting equipment is

rotating, as this can result in serious

injury.

Stop the engine and cutting equipment

before you remove material that has

wound around the blade shaft as

otherwise there is a risk of injury. The

bevel gear can get hot during use and may

remain so for a while afterwards. You

could get burnt if you touch it.

!

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 metres. 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.

!

WARNING! Sometimes branches or

grass get caught between the guard and

cutting attachment. Always stop the

engine before cleaning.

!

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.

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.

conditions, so that cleared stems fall in the cleared

area of the stand.

Grass clearing using a grass blade

• Grass blades and grass knifes must not be used on

woody stems.

• A grass blade is used for all types of tall or coarse

grass.

• The grass is cut down with a sideways, swinging

movement, where the movement from right-to-left is

the clearing stroke and the movement from left-to-

right is the return stroke. Let the left-hand side of the

blade (between 8 and 12 o’clock) do the cutting.

• If the blade is angled to the left when clearing grass,

the grass will collect in a line, which makes it easier to

collect, e.g. by raking.

• Try to work rhythmically. Stand ﬁrmly with your feet

apart. Move forward after the return stroke and stand

ﬁrmly again.

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

is used to protect the blade from hitting the ground.

• Reduce the risk of material wrapping around the blade

by following these instructions:

1Always work at full throttle.

2Avoid 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.

Grass trimming with a trimmer head

Trimming

• Hold the trimmer head just above the ground at an

angle. It is the end of the cord that does the work. Let

the cord work at its own pace. Never press the cord

into the area to be cut.

• The cord can easily remove grass and weeds up

against walls, fences, trees and borders. However it

can also damage sensitive bark on trees and bushes,

and damage fence posts.

• Reduce the risk of damaging plants by shortening the

cord to 10-12 cm and reducing the engine speed.

Clearing

• The clearing technique removes all unwanted

vegetation. Keep the trimmer head just above the

ground and tilt it. Let the end of the cord strike the

ground around trees, posts, statues and the like.

CAUTION! This technique increases the wear on the

cord.

• The cord wears quicker and must be fed forward more

often when working against stones, brick, concrete,

metal fences, etc., than when coming into contact with

trees and wooden fences.

• When trimming and clearing, you should use less than

full throttle (80%) 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.
