GENERAL SAFETY PRECAUTIONS

Important

IMPORTANT! The machine is only designed

for trimming grass.
The only accessories you can operate with
this engine unit are the cutting attachments
we recommend in the chapter on T echnical
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.
Wear personal protective equipment. See in­structions under the heading Personal
protective equipment.
Never use a machine that has been modified
in any way from its original specification.
Never use a machine that is faulty. Carry out
the checks, maintenance and service instruc­tions described in this manual. Some mainte­nance and service measures must be carried
out by trained and qualified specialists. See
instructions under the heading Maintenance.
All covers and guards mus t be fitted before
starting. Make sure the spark plug cap and
lead are not damaged. Otherwise you could
get an electric shock.
The machine operator must ensure that no
people or animals come closer than 15
metres while working. When several opera­tors are working in the same area, the safety
distance should be at least 15 metres.

WARNING: Never allow children

to use or be in the vicinity of the
machine. As the machine is equipped
with a spring--loaded stop switch and
can be started by low speed and
force on the starter handle, even
small children under some circum ­stances can produce the force neces­sary to start the machine. This can
mean a risk of serious personal inju­ry. Therefore remove the spark plug
cap when the machine is not under
close supervision.

Personal protective equipment

IMPORTANT! Whenever you use a clear-

ing saw, brushcutter or trimmer you must
wear personal protective equipment that is
approved by the authorities. Personal
protective equipment does not eliminate
the risk of accidents, but it can reduce the
effects of an injury in the event of an acci­dent. Ask your dealer for help when
choosing protective equipment.

WARNING: Listen out for warn-

ing signals or shouts when you are
wearing hearing protection. Always
remove your hearing protection as
soon as the engine stops.

HEARING PROTECTION

Wear hearing protection that provides
adequate noise reduction.

EYE PROTECTION

Always wear approved eye protection. If
you us e a visor then you must also wear
approved protective goggles. Approved
protective goggles must comply with EN
166 in EU countries.

GLOVES

Gloves should be worn when necessary,
e.g., when fitting cutting attachments.

BOOTS

Wear anti--slip and stable boots.

CLOTHING

Wear clothes made of a strong fabric and
avoid loos e clothing that can catch on
shrubs and branches. Always wear heavy,
long pants. Do not wear jewelry, shorts
sandals or go barefoot. Secure hair so it is
above s houlder level.

FIRST AID KIT

A first aid kit should be carried by opera­tors of clearing saws, brushcutters or trim­mers.

GENERAL SAFETY PRECAUTIONS

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 service workshop.

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

that has faulty safety equipment!
Follow the control, maintenance
and service instructions described
in this section. If your machine fails
any of these checks contact your
service agent to get it repaired.

Throttle lock

The throttle lock 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 lock 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.

Press the throttle lock and make sure it re­turns to its original position when you re­lease it.

Check that the throttle control and throttle
lock 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.

B

Make sure the throttle control is locked at
the idle setting when the throttle lock is re­leased.

Stop switch

Make sure the engine stops when you push
and hold the stop switch.

GENERAL SAFETY PRECAUTIONS

v

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 the
“Technical data” section.

WARNING: Never use a cutting

attachment without an approved
guard. See the section on “Technical
data”. If an incorrect or faulty guard
is fitted this can cause serious
personal injury.

Use of incorrectly wound trimmer line or an
incorrect cutting attachment increases the
level of vibration.

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 color or condition.
These symptoms normally appear
in the fingers, hands or wrists. The
risk increases at low temperatures.

Muffler

The muffler is designed to reduce the noise
level and to direct the exhaust gases away
from the operator.

In countries that ha
climate there is a significant risk of fire.
We therefore fit certain mufflers with a spark
arrestor mesh. Check whether the muffler
on your machine is fitted with this kind of
mesh.

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.

WARNING: Mufflers 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
theriskoffire!

WARNING: Theinsideofthe

muffler contain chemicals that may
be carcinogenic. Avoid contact with
these elements in the event of a
damaged muffler.

WARNING: Bear in mind that:

Engine exhaust fumes contain car­bon monoxide, which can cause
carbon monoxide poisoning. For
this reason you should not start or
run the machine indoors, or any ­where that is poorly ventilated.
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

Cutting equipment

This section describes how to choose and
maintain your cutting equipment in order to:

S Obtain maximum cutting performance.
S Extend the life of cutting equipment.

IMPORTANT!

Only use cutting attachments with the guards
we recommend! See the section on
“T echnical data”.
Refer to the instructions for the cutting attach­ment to check the correct way to load the
trimmer line and the correct line diameter.

WARNING: 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 work on it.

WARNING: A faulty cutting at-

tachment may increase the risk of
accidents.

Trimmer head

IMPORTANT!

Always ensure the trimmer line is wound
tightly and evenly around the drum, other­wise the machine will generate harmful
vibration.

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 be­cause when clearing us ing trimmer line
the engine must throw out the trimmer
line radially 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.

FUEL HANDLING

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.

Tr anspor t and storage

S 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.

S When storing and transporting fuel al-

ways use approved containers intended
for this purpose.

S When storing the machine for long peri-

ods the fuel tank must be emptied. Con­tact your local petrol station to find out
where to dispose of excess fuel.

S Ensure the machine is cleaned and that

a complete service is carried out before
long--term storage.

S 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.

Petrol

CAUTION! Always use a good quality pet-

rol/oil mixture (at least 90 octane).
Use low--emission petrol, also known as
alkylate petrol, if it is available.

S The lowest octane recommended is 90.

If you run the engine on a lower octane
than 90, it can result in knocking. This
gives rise to a high engine temperature,
which can result in serious engine damage.

S When working at continuous high revs, a

higher octane rating is recommended.

Two - -stro k e o il

S For best results and performance, use

HUSQVARNA two--stroke oil, which is
specially formulated for our two--stroke
engines. Mixture 1:50 (2%).

S If HUSQVARNA two--stroke oil is not avail-

able, you may use another two-stroke oil of
good quality that is intended for air cooled
engines. Contact your dealer when select­ing an oil. Mixing ratio 1:33 (3%).

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.

WARNING: Take care when han-

dling fuel. Bear in mind the risk of
fire, explosion and inhaling fumes.

Fuel

CAUTION! The machine is equipped with a

two- -stroke engine and must always be run
using a mixture of petrol and two-stroke
engine oil. It is important to accurately mea ­sure 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.

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.

WORKING TECHNIQUES

General working instructions

IMPORTANT!

This section descr ibes the basic safety pre­cautions for working with trimmers. If you
encounter a situation where you are uncer­tain 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 difference between
forestry clearing, grass clearing and grass
trimming before use.

Basic safety rules

1. Look around you:

S To ensure that people, animals or other

things cannot affect your control of the
machine.

S 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.

S CAU TION! 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. Working in bad
weather is tiring and often brings added
risks, such as icy ground, unpredictable
felling direction, etc.

3. 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: 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
burned 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 m. Stop the ma­chine immediately if anyone ap­proaches. Never swing the ma­chine around without first checking
behind you to make sure noone is
within the safety zone.

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.

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

Tri mming

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.

S Hold the trimmer head just above the ground

at an angle. It is the end of the trimmer line
that does the work. Let the trimmer line work
at its own pace. Never press the trimmer
lineintotheareatobecut.

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.

14

WORKING TECHNIQUES

S Reduce the risk ofdamaging plants by

shorteningthetrimmerlineto4--41/2inches
(10- -12 cm) and reducing the engine speed.

S When trimming 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. CAUTION! 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 con­tact with trees and wooden fences.

Cutting

Sweeping

S The fan effect 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: Neither the operator

of the machine nor anyone else may
attempt to remove the cut material
while the engine is running or the
trimmer line is rotating, as this can
result in serious injury. Stop the
engine and trimmer head before you
remove material that has wound
around the drive 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 burned if you touch it.

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.

WARNING: Watch out for thrown

objects. Always wear 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 unauthorized persons at a dis­tance. Children, animals, onlookers
and helpers should be kept outside
thesafetyzoneof15m.
Stop the machine immediately if
anyone approaches.

MAINTENANCE

f

The owner is responsible
mance of all required maintenance as
defined in the operator’s manual.

Carburetor

Your Husqvarna product has been designed
and manufactured to specifications that re­duce 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 harm­ful exhaust emissions after the run--in peri­od, ask y our servicing dealer to adjust your
carburetor.

WARNING: The complete clutch,

clutch cover, and shaft must be
fitted before the machine is started,
otherwise parts could come loose
and cause personal injury.

or the perfor-

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--s crew 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.

Idle Speed
Screw--T

WARNING: If the idle speed can -

not be adjusted so that the cutting
attachment stops, contact your ser ­vicing dealer. Do not use the ma­chine until it has been correctly ad­justed or repaired.

Unit/Maintenance Safety

Disconnect the spark plug before perform­ing maintenance, except carburetor adjust­ments.

Muffler

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.

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.

Fine adjustment of the idle speed -- T

Adjust the idle speed using the idle adjust­ment 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 counter­clockwise until the cutting attachment stops.
The idle speed is correctly adjusted when
the engine will run smoothly in every posi­tion. The idle speed should also be well
below the speed at which the cutting attach­ment starts to rotate.

Mufflers are equipped with a special spark
arrestor mesh. Y ou should clean the mesh
at least once a month. This is best done
withawirebrush.If the mesh is damaged
it should be replaced. 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.

MAINTENANCE

WARNING: Mufflers get very hot

during use and remain so for some
time after stopping. This also ap ­plies at idle speed. Contact can re­sult in burns to the skin. Remember
theriskoffire!

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:

Engine exhaust fumes contain car ­bon monoxide, which can cause
carbon monoxide poisoning. For
this reason you should not start or
run the machine indoors, or any ­where that is poorly ventilated.
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!

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 operat­ing 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 ac tion. If the spark plug is dirty,
clean it and check that the electrode gap is
0,6 mm. The spark plug should be replaced
after about a month in operation or earlier if
necessary.

0,6 mm

Two-- piece shaft

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) will seize if they
are not lubricated regularly.

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 Unnec essary 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.

CAUTION! Always use the recommended

spark plug type! Use of the wrong spark
plug can damage the piston/cylinder.

MAINTENANCE

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.

rotate at idle.

Clean the air filter. Replace if necessary.

Check that the guard is undamaged and not
cracked. Replace the guard if it has been
exposed to impact or is cracked.

Check that the trimmer head is undamaged
and not cracked. Replace the trimmer head
if necessary.

Check that nuts and screws are tight.

Check that there are no fuel leaks from the
engine, tank or fuel lines.

Check the starter and starter cord.

Clean the outside of the spark plug. Re­move it and check the electrode gap. Adjust
the gap to 0,6 mm or replace the spark plug.
Check that the spark plug is fitted with a
suppressor.

Clean the outside of the carburetor and the
space around it.

Check that the bevel gear is filled three-­quarters full with lubricant. Fill if necessary
using s pecial grease.

Check the fuel filter from contamination and
the fuel hose from cracks or other defects.
Replace if necessary.

Check all cables and connections.

Check the clutch, clutch springs and the
clutch drum for wear. Replace if necessary
by an autorized service workshop.
