GENERAL SAFETY PRECAUTIONS
Important

Personal protective equipment

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 section 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.
Never use the machine in extreme weather
conditions such as severe cold, very hot and/
or humid climates.
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 must 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.

IMPORTANT! 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. Ask your dealer for help in
choosing the right equipment.

WARNING: Listen out for warning signals or shouts when you are
wearing hearing protection. Always
remove your hearing protection as
soon as the engine stops.
HELMET
A helmet should be worn if the brush being
cleared is taller than 2 metres.

HEARING PROTECTION
Wear hearing protection that provides
adequate noise reduction.

WARNING: Using an incorrect
cutting attachment or an incorrectly
filed blade can increase the risk of
accidents.

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

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 circumstances 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.

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

BOOTS
Wear anti--slip and stable boots.

GENERAL SAFETY PRECAUTIONS
CLOTHING
Wear clothes made of a strong fabric and
avoid loose 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 shoulder level.
FIRST AID KIT
A first aid kit should be carried by operators of clearing saws, brushcutters or trimmers.

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

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.

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

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.

Check that the throttle control and throttle
lock move freely and that the return springs
work properly.

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.

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

GENERAL SAFETY PRECAUTIONS
Stop switch

Harness quick release

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

There is an easily accessible, harness
quick release fitted at the front in case of an
emergency that requires you to free yourself from the machine and harness.
See instructions under the heading Adjusting the harness.

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 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 reduce the noise
level and to direct the exhaust gases away
from the operator.
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.

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 mesh. Check whether the muffler
on your machine is fitted with this kind of
mesh.

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.

Muffler bolts

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

Spark arrestor mesh

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.

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.

GENERAL SAFETY PRECAUTIONS
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.
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 the risk
of fire!

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

WARNING:

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

This section describes how to choose and
maintain your cutting equipment in order to:
S Reduce the risk of blade thrust.
S Obtain maximum cutting performance.
S Extend the life of cutting equipment.

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 anywhere 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!

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

Locking nut

A locking nut is used to secure some types
of cutting attachment.

WARNING: Using an incorrect
cutting attachment or an incorrectly sharpened blade increases the
risk of kickback.

GENERAL SAFETY PRECAUTIONS
Cutting equipment

Sharpening grass cutters and
grass blades

Grass blades and grass cutters are intended for cutting coarse grass.

S See the cutting attachment packaging for
correct sharpening instructions. Sharpen
blades and cutters using a single--cut flat file.
S Sharpen all edges equally to maintain the
balance of the blade.

A trimmer head is intended for trimming
grass.

General rules

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.

Only use cutting attachments with the
guards we recommend! See the section on
Technical data.

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

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.

S Only use the recommended cutting attachments. See the section on “Technical
data”.

S Smaller machines generally require small
trimmer heads and vice versa. This is because when clearing using 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 important. 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.

Check the cutting attachment for damage
or cracks. A damaged cutting attachment
should always be replaced.

ASSEMBLY
NOTE: Make sure unit is assembled correctly as shown in this manual.

NOTE: Fit throttle wire in groove of lower
harness clamp before tightening screws.

FUEL HANDLING
Fuel safety

Petrol

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.

CAUTION! Always use a good quality petrol/oil mixture (at least 90 octane).
Use low--emission petrol, also known as
alkylate petrol, if it is available.

Transport 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 always use approved containers intended
for this purpose.
S 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.
S Ensure the machine is cleaned and that
a complete service is carried out before
long--term storage.
S The transport guard must always be
fitted to the cutting attachment when the
machine is being transported or in 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.

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--stroke oil
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 available, 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.

Min. 3 m

STARTING AND STOPPING
Check before starting

Starting and stopping

S 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.

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.
Always move the machine away
from the refueling area before
starting. Place the machine on a
flat surface. Ensure the cutting attachment cannot come into contact
with any object.
Make sure no unauthorized
persons are in the working area,
otherwise there is a risk of serious
personal injury. The safety
distance is 15 meters.

S 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.

Cold engine
Primer bulb: Press the primer bulb 10
times until fuel begins to fill the bulb. The
primer bulb need not be completely filled.

S 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.
Choke: Move the blue engine choke lever
over to the closed position.

S 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

Stop the engine by pushing and holding
the stop switch in the STOP position until
the engine stops.

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.

CAUTION! The stop switch automatically
returns to the start position. In order to prevent unintentional starting, the spark plug
cap must be removed from the spark plug
when assembling, checking and/or performing maintenance.

WARNING: When the engine is
started with the choke in the closed
position the cutting attachment will
start to rotate immediately.

Always use the correct equipment.
Make sure the equipment is well adjusted.
Follow the safety precautions.
Organise your work carefully.
Always use full throttle when starting to cut
with the blade.
S Always use sharp blades.
S Avoid stones.

IMPORTANT!
This section describes the basic safety precautions for working with trimmers. If you
encounter a situation where you are uncertain how to proceed you should ask an expert. 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 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. 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.
WARNING: Sometimes branches
or grass get caught between the
guard and cutting attachment.
Always stop the engine before
cleaning.
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.

4. Switch off the engine before moving to
another area. Fit the transport guard before
carrying or transporting the equipment any
distance.
5. Never put the machine down with the engine
running or while the cutting attachment is
rotating.

WORKING TECHNIQUES
Grass clearing using a grass blade

Grass trimming with a trimmer head
Trimming

S Grass blades and grass cutters must not be
used on woody stems.
S A grass blade is used for all types of tall or
coarse grass.
S 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.

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
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.
S Reduce the risk of damaging plants by
shortening the trimmer line to 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 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.
S Try to work rhythmically. Stand firmly with
your feet apart. Move forward after the return stroke and stand firmly again.
S Let the support cup rest lightly against the
ground. It is used to protect the blade from
hitting the ground.
S Reduce the risk of material wrapping
around the blade by following these instructions:
S Always work at full throttle.
S Avoid the previously cut material during
the return stroke.
S Stop the engine, unclip the harness and
place the machine on the ground before
you start to collect the cut
material.

S The clearing technique removes all unwanted 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.

WORKING TECHNIQUES
Cutting

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.

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
the safety zone of 15 m.
Stop the machine immediately if
anyone approaches.

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.
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.

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

Idle Speed
Screw--T

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 your servicing dealer to adjust your
carburetor.

WARNING:

If the idle speed cannot be adjusted so that the cutting
attachment stops, contact your servicing dealer. Do not use the machine until it has been correctly adjusted or repaired.

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.

Unit/Maintenance Safety
Disconnect the spark plug before performing maintenance, except carburetor adjustments.

Function

Muffler
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.

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.

Basic setting
S The basic carburetor settings are adjusted 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.
Rec. idle speed:
See “Technical data” section.
Recommended max. speed:
See “Technical data” section.

Mufflers are equipped with a special spark
arrestor mesh. You should clean the mesh
at least once a month. This is best done
with a wire brush. 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.

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.

Muffler bolts
Spark arrestor mesh

CAUTION! Never use a machine that has
a faulty or loose muffler. Ensure the muffler
bolts are tight.

MAINTENANCE
Air filter

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
the risk of fire!

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

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 carbon monoxide, which can cause
carbon monoxide poisoning. For
this reason you should not start or
run the machine indoors, or anywhere 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!

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.

Spark plug

The spark plug condition is influenced by:
S Incorrect carburetor adjustment.
S An incorrect fuel mixture (too much or incorrect 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 action. 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

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.

CAUTION! Always use the recommended
spark plug type! Use of the wrong spark
plug can damage the piston/cylinder.

The grease in the bevel gear does not normally need to be changed except if repairs
are carried out.

MAINTENANCE
Sharpening grass cutters and
grass blades

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.
S See the cutting attachment packaging for
correct sharpening instructions.
S Sharpen blades and cutters using a
single--cut flat file.
S Sharpen all edges equally to maintain the
balance of the blade.

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.
