SAFETY INSTRUCTIONS

Muffler

S Never use a machine that has a faulty

muffler .

S Regularly check that the muffler is securely

attached to the machine.

S The muf fler on this unit is equipped with a

special spark arrestor mesh. The mesh

should be checked and, if necessary .

cleaned by a servicing dealer. A blocked

mesh will cause the machine to overheat,

which can lead to serious damage. Never

use a muffler with a defective spark arres-

tor mesh. See the Maintenance section.

Cutting equipment

This section describes how to choose and

mainta in your cutting equipm ent in order to:

S Obtain maximum cutting performance.

S Extend the life of cutting equipment.

General rules

1. Only use cutting attachm ents with the

guards we recommend! See the section

on “Technical Data”.

2. Check the cutting attachment for damage

or cracks. A damaged cutting attachment

should always be replaced.

IMPORT ANT!

This section describes how to choose and

mainta in your cutting equipm ent in order to:

Obtain maximum cutting performance.

Extend the life of cutting equipment.

Only use cutting attachments with the guards

we recommend! See the section on

“Technical data”.

Refer to the instructions for the cutting attach-

ment to check the correct way to load the

trimmer line and the correct line diameter .

Trimmer he a d

S Only use the recommended cutting at-

tachments. See the section on “Technical

data”.

S Smaller machines generally require small

trimmer heads and vice versa. This is be-

cause when clearing using trimmer line the

engine must throw out the trimmer line ra-

dially from the trimmer head and overcome

the resistance of the grass being cleared.

S The length of the trimmer line is also im-

portant. A longer trimmer line requires

greater engine power than a shorter

trimmer line of the same diameter.

S Make sure that the cutter on the trimmer

guard is intact. This is used to cut the

trimmer line to the correct length.

S To increase the life of the trimmer line it

can be soaked in water for a couple of

days. This will make the line tougher so

that it lasts longer .

IMPORT ANT!

Always ensure the trimmer line is wound

tightly and evenly around the drum, other-

wise the machine will generate harmful

vibration.

W ARNING: Always stop the en-

gine 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

lead from the spark plug before

you start to w ork on it.

W ARNING: Never use a machine

with faulty safety equipm ent. 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 servicing dealer to get

it repaired. Use of a machine with

faulty safety equipm ent increa ses

the risk of serious personal injury to

the operator or others.

General working instructions

IMPORTANT!

This section describes the basic safety pre-

cautions for working with trimmers. If you

encounter a situation where you are uncer-

tain how to proceed you should ask an ex-

pert. Contact your servicing dealer .

Avoid all usage which you consider to be

beyond your capability.

You must understand the dif ference between

forestry cle aring, grass cleari ng and grass

trimming before use.

Basic safety rules

1. Look around you:

S To ensure that people, animals or other

things cannot af fect your control of the

machine.

S To ensure that people, animals, etc.,

do not come into contact with the cut-

ting attachment or loose objects that

are thrown out by the cutting attach-

ment.

WARNING: T ake care when han-

dling fuel. Bear in mind the risk of

fire, explosion and inhaling fumes.

English---9

115374427 Rev. 6 5/15/12

SAFETY INSTRUCTIONS

3. M a ke sure yo u ca n mo ve and stan d safe ly.

Check the area around you for possible ob-

stacles (roots, rocks, branches, ditches, etc.)

in case you have to move suddenly. Take

great care when working on sloping ground.

4. Switch off the engine before moving to

another area.

5. Never put the machine down with the engine

running or while the cutting attachment is

rotating .

Basic working techniques

S 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.

S It is recommended that the engine not

be operated for longer than 1 minute at

full throttle.

Grass tri mming using a trimmer head

Trimming

S Hold the trimmer head just above the

ground at an angle. It is the end of the trim-

mer line that does the work. Let the trim-

mer line work at its own pace. Never press

the trimmer line into the area to be cut.

S The trimmer line 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.

W ARNING: Sometime s branc hes

or grass get caught between the

guard and cutting attachment.

Always stop the engine before

cleaning.

S CAUTION! Do not use the machine

unless you are able to call for help in

the event of an accident.

2. Do not use the machine in bad weather ,

such as dense fog, heavy rain, strong

wind, intense cold, etc. W orking in bad

weather is tiring and often brings added

risks, such as icy ground, unpredictable

felling direction, etc.

S Reduce the risk o

damaging plants by

shortening the trimmer line to 4--4 1/2 inches

(10--12 cm) and reducing the engine speed.

S When tr imming you should use less than

full throttle so that the trimmer line lasts

longer and to reduce the wear on the

trimmer head.

Clearing

S The clearing technique removes all un-

wanted vegetation. Keep the trimmer

head just above the ground and tilt it. Let

the end of the trimmer line strike the

ground around trees, posts, statues and

the like. IMPORTANT! This technique

increases the wear on the trimmer line.

S The trimmer line wears quicker and must

be fed forward more often when working

against stones, brick, concrete, metal

fences, etc., than when coming into con-

tact with trees and wooden fences.

Cutting

S The trimmer is ideal for cutting grass that

is difficult to reach using a normal lawn

mower . Keep the trimmer line parallel to

the ground when cutting. Avoid pressing

the trimmer head against the ground as

this can ruin the lawn and damage the

tool.

S Do not allow the trimmer head to con--

stantly come into contact with the ground

during normal cutting. Constant contact

of this type can cause damage and wear

to the trimmer head.

English---10

115374427 Rev. 6 5/15/12

SAFETY INSTRUCTIONS

Sweeping

S The fan ef fect of the rotating line can be

used for quick and easy clearing up.

Hold the trimmer line parallel to and

above the area to be swept and move

the tool to and fro.

S When cutting and sweeping you should

use full throttle to obtain the best results.

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 dis-

tance. 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 ma-

chine 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 or wrapped around the

shaft. Neither the operator of the

machine nor anyone else may at-

tempt 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 equip-

ment before you remove material.

HUSQV ARNA two--stroke oil, which is

specially formulated for our two--stroke

engines. Mixture 1:50 (2%).

S To maximize the life of your trimmer, you

may choose to use a high quality syn-

thetic oil formulated for two--stroke

engines. Mixture 1:50 (2%).

S Never use two--stroke oil intended for

water--cooled outboard engines,

sometimes referred to as outboard oil.

S Never use oil intended for four--stroke

engines.

W ARNING: Fuel and fuel fumes

are highly flammable and can cause

serious injury when inhaled or al-

lowed to come in contact with the

skin. For this reason, observe cau-

tion when handling fuel and make

STARTING AND STOPPING

Warm engine

With a warm engine, move the blue engine

choke lever to the ½ position. Pull starter

rope until engine runs. Move the blue

engine choke lever to the opened position.

W ARNING: When the engine is

started with the choke in the closed

position the cutting attachment will

start to rotate immediately.

Stopping

Stop the engine by pushing and holding

the stop switch in the STOP position until

the engine stops.

MAINTENANCE

Carburetor

Your Husqvarna product has been designed

and manufactured to specifications that re-

duce 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 minimize harm-

ful exhaust emissions after the run--in peri-

od, ask your servicing dealer to adjust your

carburetor.

The owner is responsible for the per

or-

mance of all required maintenance as

defined in the operator’s manual.

W ARNING: The complete clutch,

clutch cover , and shaft must be

fitted before the machi ne is started,

otherwise parts could come loose

and cause personal injury .

Function

S The carburetor governs the engine’s

speed via the throttle control. Air and fuel

are mixed in the carburetor.

S 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 counterclockwise gives a lower

idle speed.

Basic setting

S The basic carburetor settings are ad-

justed during testing at the factory. Fine

adjustment should be carried out by a

skilled technician.

CAUTION! If the cutting attachment rotates

when the engine is idling the idle adjustment

screw T should be turned counterclockwise

until the cutting attachment stops.

W ARNING: The cutting attach-

ment ma y be spinning during carbu-

retor adjustme nts. Wear your protec-

tive equipment and observe all safe-

ty instructions . Be sure the cutting

attachm ent stops turning when the

engine idles. When the unit is turned

off, make sure the cutting attach-

ments has stopped before the unit is

set down.

Rec. idle speed:

See “Technical data” section.

Recommended max. speed:

See “Technical data” section.

Fine adjustment of the idle speed--T

Adjust the idle speed using the idle adjust-

ment 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 counterc-

lockwise until the cutting attachment stops.

The idle speed is correctly adjusted when

the engine will run smoothly in every posi-

tion. The idle speed should also be well

below the speed at which the cutting at-

tachment starts to rotate.

WARNING: Improper mainte-

nance could result in serious engine

damage or in serious injury .

115374427 Rev. 6 5/15/12

MAINTENANCE

W ARNING: If the idle speed can-

not be adjusted so that the cutting

attachment stops, contact your ser-

vicing dealer . Do not use the ma-

chine until it has been correctly ad-

justed or repaired.

Unit/Maintenance Safety

Disconnect the spark plug before perform-

ing maintenance, except carburetor adjust-

ments.

Muffler

CAUTION! Muffler is fitted with a catalytic

converter designed to reduce exhaust gas

emissions.

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 com-

bustible material.

Mufflers are equipped with a special spark

arrestor mesh. The mesh should be

checked and, if necessary. cleaned by a

servicing dealer. If the mesh is damaged,

it should be replaced. Ifthemeshisfre-

quently blocked, this can be a sign that the

performance of the catalytic converter is

impaired. Contact your servicing dealer to

inspect the muffler. A blocked mesh will

cause the machine to overheat and result

in damage to the cylinder and piston.

CAUTION! Never use a machine that has

a faulty or loose muffler. Ensure the muffler

bolts are tight.

Muffler bolts

Spark plug

The spark plug condition is influenced by:

S Incorrect carburetor adjustment.

S An incorrect fuel mixture (too much or in-

correct type of oil).

S A dirty air filter .

These factors cause deposits on the spark

plug electrodes, which may result in operat-

ing 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

0.024″ (0.6 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.

0.024″ (0.6 mm)

Spark arrestor mesh

W ARNING: The inside of the

muffler contain chemicals that may

be carcinogenic. Avoid contact

with these elements in the event of

a damaged muffler.

CAUTION: Mufflers fitted with cata-

lytic converters get very hot during use

and remain so for some time after stop-

ping. This also appli es at idle speed. Con-

tact can result in burns to the skin. Re-

member the risk of fire!

WARNING: Engine exhaust

fumes contain carbon monoxide,

which can cause carbon monoxide

poisoning. DO NOT

start or run the

machine indoors, or any where that

is poorly ventilated. The exhaus t

fumes from the engine are hot and

may contain sparks which can start

a fire. Never start the machine in-

doors or near combustible material!

MAINTENANCE

Air filter

The air filter must be regularly cleaned to

remove dust and dirt in order to avoid:

S Carburetor malfunctions

S Starting problems

S Loss of engine power

S Unnecessary wear to engine parts

S Excessive fuel consumption

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 .

Rinse thoroughly. Ensure that the filter is dry

before refitting it.

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.

Maintenance schedule

Below you will find some general mainte-

nance instructions.

Daily maintenance

S Check throttle trigger and throttle trigger

lockout function.
