SAFETY INSTRUCTIONS
Personal protective equipment
IMPORTANT INFORMATION
•
•
Incorrect or careless use of a clearing saw,
brushcutter or trimmer can turn it into a dangerous
tool that can cause serious or even fatal injury to
the operator or others. It is extremely important
that you read and understand the content of this
manual.
When using a clearing saw, brushcutter or trimmer,
protective equipment approved by the appropriate
authorities must be used. Personal protective
equipment does not eliminate the risk of accidents,
however, it can reduce the effects of an injury in
the event of an accident. Ask your dealer for help
when choosing protective equipment.
The machine‘s safety equipment
This section describes the machine‘s safety equipment, its
function and how checks and maintenance are carried out to
ensure that it operates correctly. (See the chapter “What is
what“ to locate where this equipment is positioned on your
machine.)
!
WARNING!
Never use a machine with defective safety
equipment. Follow the control,
maintenance and service instructions
described in this section.
1. Throttle trigger
lock
A
HELMET
A helmet should be worn if
trees to be cleared are higher
than 2 metres.
EAR PROTECTION
Ear protection offering
sufficient dampening effect
should be used.
EYE PROTECTION
Blows from branches or
objects thrown by the
rotating cutting equipment
can damage the eyes.
GLOVES
Gloves should be worn
when necessary, e.g., when
assembling cutting
equipment.
BOOTS
Use anti-slip and stable
boots.
CLOTHING
Wear clothes made of a
strong fabric and avoid loose
clothing that can catch on
shrubs and branches. Always
wear heavy-duty long pants.
Do not wear jewellery,
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.
4 – English
The throttle trigger lock is
designed to prevent the
throttle from accidentally
being engaged. When the
trigger lock (A) is pressed
into the handle (= when you
hold the handle) the throttle
(B) is released. When the
grip on the handle is
released the throttle and the
throttle trigger lock return
to their original positions.
This takes place via two
independent return spring
systems. This means that the
throttle is automatically
locked in its “idling“
position.

SAFETY INSTRUCTIONS
2. Stop switch
The stop switch should be
used to stop the engine.
4. Anti-vibration
system
Your machine is equipped
with an anti-vibration system
that has been designed to
give as vibration-free and
comfortable usage as
possible.
The use of incorrectly
wound cord or blunt,
incorrect cutting equipment
(incorrect type or incorrectly
sharpened, see section “Filing
the blade”) increases the level
of vibration.
The machine’s vibration
damping system reduces the
transfer of vibrations
between the engine unit/
cutting equipment and the
machine’s handle unit.
!
3. Cutting
attachment guard
This guard is intended to
prevent objects from being
thrown towards the operator
and to protect the operator
from unintentionel contact
with the cutting attachment.
!
WARNING!
Do not attach any blade to the unit
without proper installation of all required
parts. Failure to use the proper parts can
cause the blade to fly off and seriously
injure the operator and/or bystanders.
WARNING!
Over exposure to vibrations can result in
blood-vessel or nerve injury to persons
suffering with blood circulation problems.
Seek medical attention if you experience
physical symptoms that can be related to
over exposure to vibrations. Examples of
such symptoms are “numbness“, lack of
feeling, “tickling“, “pricking“, “pain“, lack
of or a reduction in normal strength,
changes in the colour of the skin or its
surfaces. These symptoms normally
appear in the fingers, hands or wrists.
5. Quick-release
There is an easily accessible,
quick-release catch fitted to
the chest as a safety
precaution in the event of a
fire in the engine or for any
other situation that requires
you to free yourself from the
machine and harness. See the
section “Adjusting the harness
and clearing saw“.
Under no circumstances may the cutting
equipment be used without an approved
guard fitted. See the chapter “Technical
data”. If the wrong guard or a defective
guard is fitted this can cause serious
personal injury.

SAFETY INSTRUCTIONS
6. Muffler
The muffler is designed to
give the lowest possible noise
level and to direct the
engine‘s exhaust fumes away
from the operator. Muffler
fitted with catalytic
converter is also designed to
reduce harmful exhaust
components.
In countries that have a
warm and dry climate the
risk of fire is obvious. We
have therefore fitted certain
mufflers with a spark arrest
screen. Make sure that your
muffler is fitted with this
kind of screen.
It is extremely important
that the instructions for
checking, maintaining and
servicing the muffler are
followed. (See the section
“Control, maintenance and
service of the machine‘s safety
equipment“.)
!
!
6 – English
WARNING!
Mufflers fitted with catalytic converters
become extremely hot during use and
after stopping. This also applies at idling
speeds. Contact can result in burns to
the skin. Be observant to the risk of fire!
WARNING!
Bear in mind that exhaust fumes:
• contain carbon monoxide, which can
cause carbon monoxide poisoning.
Therefore never start or run the machine
indoors.
• are hot and can contain sparks that can
cause fires. Never start the machine
indoors or close to inflammable material.

SAFETY INSTRUCTIONS
6. Cutting equipment
7. Quick-release
This section describes how through correct maintenance and
through using the right type of cutting equipment you can:
• Reduce the machine‘s tendency to kickback
• Obtain maximum cutting capacity.
• Increase the service life of the cutting equipment.
• Check that the harness
straps are correctly
positioned. When the
harness and machine are
adjusted, check the harness‘
safety release catch to
ensure it works correctly.
Four basic rules:
1)Only use the cutting
and guard equipment
we recommend! See
chapter “Technical
data“.
2)Keep the blade‘s teeth
well and correctly
sharpened! Follow our
instructions and use the
recommended filing
gauge. An incorrectly
sharpened or damaged
blade increases the risk
of an accident.
3)Keep the correct setting.
Follow our instructions
and use the
recommended setting
tool. An incorrectly set
blade increases the risk
of jamming and
kickback.
4)Check the cutting
equipment with regard
to damage and crack
formation. Damaged
cutting equipment
should always be
replaced.
8. Locking nut
• Protect your hand from
injury when assembling,

Cutting equipment
Sharpening the
grass blade
IMPORTANT INFORMATION
The section describes how through correct maintenance and through using the right type of cutting
equipment you can reduce the machine‘s tendency to
kickback, obtain maximum clearing capacity and
increase the service life of the cutting equipment.
•
Only use the cutting and guard equipment we
recommend! See chapter “Technical data“.
•
Refer to the instructions for the cutting
equipment for the correct winding of cord
and for the selection of the right cord diameter.
•
Keep the blade’s teeht well and correctly
sharpened! Follow our recommendations. Also
refer to the instructions on the blade packaging.
•
Maintain the correct setting. Follow our instructions and use the recommended filing gauge.
!
WARNING!
Incorrect cutting equipment or an
incorrectly sharpened blade increases
the risk of kickback.
Sharpening the
clearing blade
• See the cutting
equipment’s packaging for
correct filing instructions.
• A correctly sharpened
blade is a prerequisite for
working efficiently and to
avoid unnecessary wear to
the blade and clearing saw.
• Make sure that the blade is
well supported when you
use the file. Use a 5,5 mm
round file with a file
holder.
• The sharpening angle is
15°. Every other tooth is
sharpened to the right and
the intermediate tooth to
the left. When the blade
has been heavily pitted by
stones the upper side of
the teeth can, in
exceptional cases, need to
be dressed using a flat file.
In such cases this takes
place before sharpening
with the round file.
Dressing the top side must
be carried out equally for
all teeth.
• Adjust the setting. This
should be 1 mm.
10 – English
• See the cutting
equipment’s packaging for
correct filing instructions.
• The blades are sharpened
using a single cut flat file.
• Sharpen all edges equally
to maintain the balance of
the blade.
Trimmer head
• Only use a trimmer head
and trimmer cord that is
recommended. 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
cutting equipment we
recommend! See chapter
“Technical data“.
• Generally smaller machines require a small trimmer head
and vice versa. This is because when clearing using a cord
the engine must throw out the cord radially from the
trimmer head and also meet resistance from 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 the knife positioned 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 few days. This will make the line tougher and it will keep
longer.
IMPORTANT INFORMATION
Always ensure the trimmer cord is wound tightly
and evenly around the drum, otherwise harmful
vibrations will occur.
!
WARNING!
Always stop the engine before starting
work on any part of the cutting equipment.
This continues to rotate even after the
throttle has been released. Ensure that the
cutting equipment has stopped completely
and remove the cable from the spark plug
before you start to work on it.

SAFETY INSTRUCTIONS
General working instructions
IMPORTANT INFORMATION
•
This section takes up the basic safety precautions
for working with the clearing saw and trimmer.
•
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
clearing, brush cutting and grass trimming before
using the machine.
Basic safety precautions
4. Take great care when
cutting a tree that is subject
to tension. A tree that is
under tension can spring
back to its original position
both before and after being
cut. Incorrect positioning
on your behalf or when
positioning the cut can
result in the tree hitting you
or the machine so that you
lose control. Both situations
can cause serious personal
injury.
5. The engine should be
switched off before moving.
When moving over longer
distances and transporting
the transport guard should
be used.
1. Observe your surroundings:
• To ensure that people, animals or other things cannot affect
your control of the machine.
• To ensure that the above mentioned do not come into
contact with the cutting equipment or objects that can be
thrown by the cutting equipment.
• NOTE! Never use a machine without the possibility of
calling for help in the event of an accident.
2. Avoid usage in
unfavourable weather
conditions. For example,
thick fog, heavy rain,
strong winds or extreme
cold, etc. To work in bad
weather conditions is
tiring and can create
dangerous circumstances,
e.g. slippery surfaces,
affect a tree‘s direction of
fall, etc.
3. Make sure you can walk
and stand safely. Look out
for any obstacles with
unexpected movement
(roots, stones, branches,
pits, ditches, etc.). Take
great care when working
on sloping ground.
12 – English
6. Never put the machine
down with the engine
running unless you have
good sight of it.
SAFETY INSTRUCTIONS
Adjusting the harness and clearing saw
!
WARNING!
When working with the clearing saw it
should always be hooked in the harness. If
this is not done, you cannot control the
clearing saw safely and this can result in
injury to yourself or someone else. Never
use a harness with a defective quick
release catch.
Quick release
On the front is an easily
accessible, quick release
catch. Use this if the engine
should catch fire or in any
other emergency situation
when you quickly need to
take off the harness and
machine.
Even load on the
shoulders
A well-adjusted harness and
clearing saw significantly
facilitates working. Adjust
the harness for the best
working position. Tension
the side straps so that the
weight is evenly distributed
across the shoulders.
Correct height
1) Forestry clearing
Adjust the carrier strap so
that the suspension hook
comes approximately 10
cm under the hip. The
blade should be angled
forward a little.
Basic clearing techniques
• Always carry out clearing and trimming at full throttle.
• Always drop to idling speed after each working operation.
Longer periods running at full throttle without loading the
engine (that is without resistance, which the engine feels
from the cutting equipment when trimming) can lead to
serious engine damage.
Designations
• Forestry clearing is a
general term for cutting
small trees where each
stem is cut individually.
A saw blade is used.
• Brush cutting is a general
term for clearing grass.
Grass blades are used for
this purpose.
• Grass trimming is a
general term for light
clearing, e.g. around
edges or around trees. A
trimmer head or plastic
blade is used.
!
WARNING!
Sometimes branches, grass or wood can
get caught between the guard and cutting
equipment. Always stop the engine when
cleaning.
2)Grass clearing
The suspension hook
should hang
approximately 20 cm
under the hip so that the
blade is parallel to the
ground.
Correct balance
1)Forestry clearing
Move the suspension eye
forwards or backwards. If
the blade is balanced a 1020 cm above the ground it
is easier to avoid stones.
2)Grass clearing
Let the blade balance at a
comfortable clearing
height, i.e. close to the
ground.

D.
E.
F.
G.
H.
Always use the correct equipment.
Always have well adjusted equipment.
Follow the safety instructions.
Organise the work well.
Always use full throttle when applying the blade.
Always use a sharp blade.
Avoid stones.
Guide the direction of fall (use the wind).
!
WARNING!
Avoid cutting in the cutting region
between 12 and 3 o‘clock on the blade.
Kickback can occur due to the blade‘s
rotation speed in this area of the blade
when applied on thick stems.
Working methods
• Before you start clearing, check the clearing area, its
condition, slopes, if there are stones, pits, etc.
• Thereafter start at the end which is easiest, and make a good
start to the clearing.
• Work systematically to
and from and across the
area. Each stroke should
encompass a working
area of 4-5 metres. This
then utilises the full
working area of the
machine in both
directions and provides
the operator with an easy
and variable working
area to work through.
• The length of the
pathway should be
approx. 75 m. Move the
fuelling station as work
progresses.
Forestry clearing
using a saw blade
• When applying the blade
to heavier stems the risk of
kickback increases. You
should therefore avoid
applying the blade on the
cutting area between 12
and 3 o‘clock.
• To fell to the left, the
lower section of the tree
should carry to the right.
Angle the blade and move
it with a resolute
movement diagonally
down to the right. At the
same time press against the
stem using the blade
guard. Apply the blade on
the area between 3-5
o‘clock. Use full throttle
when applying the blade.
• To fell to the right, the
lower section of the tree
should carry to the left.
Angle the blade and move
it with a resolute
movement diagonally up
to the left. Apply the blade
on the area between 3 and
5 o‘clock so that the
blade‘s direction of
rotation carries the lower
section of the tree to the
left.
• On sloping ground the
pathway should run
parallel to the slope. It is
far easier to work along a
slope then up and down
a slope.
• The pathway should be
planned so that you
avoid going over ditches
or other obstacles. Also
adapt the pathway to the
wind conditions so that
the cleared stems fall on
the part of the stand that
has been cleared.
14 – English
• To fell a tree forwards the
lower section of the tree
should be drawn
backwards. Draw the blade
backwards with a quick
and resolute movement.
SAFETY INSTRUCTIONS
• Large stems must be cut
from two sides.
Determine in which
direction the stem
should fall. First apply
the saw to the felling
side. Then cut from the
other side to fell the
stem. The feed pressure
should be applied with
regard to the size of the
stem‘s hardness. Small
stems require more
pressure, while large
stems require less
pressure.
• If the stems are tightly
packed adapt the
through-speed with this
in mind.
• If the blade should jam in the stem, never jerk the
machine free. If you do this the blade, angle gear, shaft or
the handlebars can be damaged. Release the handlebars
and grip the shaft with both hands and slowly pull the
machine free.
Brush cutting using a grass blade
• A blade is used for all
types of high or thick
grass.
• The grass is cut down
with a sideways, swinging
movement, where the
movement from right-toleft is the clearing stroke
and the movement from
left-to-right is the return
stroke. Let the blade work
on the left-hand side
(between 8 and 12
o’clock).
• If the blade is angled to the left when clearing the grass will
collect in a line, which makes collection easier, e.g. when
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.
Brush cutting
using the saw
blade
• Reduce the risk of material wrapping around the blade by
following these instructions:
a) Always work at full throttle.
b) Avoid the previously cut material during the return
stroke.
• Thin stems and brush are
mown down. Work by
swinging the machine
sideways.
• Stop the engine and remove the brushcutter from the
harness before you start to gather the cut material.
• Try to cut several stems in
one movement.
• With groups of hardwood
stems, first clear around
the group. Cut high on
the stems around the
outside of the group to
avoid jamming. Now cut
the stumps to the
required height. Now try
to come in with the blade
and cut from the centre of
the group. If it is still
difficult to gain access, cut
long stumps and let the
stems fall down. This will
reduce the risk of
jamming.
!
!
WARNING!
Neither the user of the tool or anyone else
may attempt to remove the cut material
while the engine is running or with the
blade rotating as this can result in serious
injury.
Stop the engine and blade before you
remove material that has wound around the
blade as otherwise there is a risk of injury.
WARNING!
Beware of thrown objects. Always wear eye
protection. Never lean over the guard.
Stones, rubbish etc. can be thrown up into
the eyes resulting in blindness or other
serious injury.
Keep unauthorised persons at a distance.
Children, animals, onlookers and helpers
should be outside the safety zone of 15
meters (50 feet). Stop the machine
immediately if anyone approaches.

SAFETY INSTRUCTIONS
Grass clearing
using the trimmer
head
• Hold the trimmer head
just above the ground at
an angle. It is the end of
the cord that carries out
the work. Let the cord
work at its own pace.
Do not 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. NOTE! 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 so
that the cord lasts longer
and to reduce the wear
on the trimmer head.
16 – English
Trimming
• The trimmer is ideal to
cut 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.
• Do not allow the
trimmer head to
constantly come into
contact with the ground
during normal cutting
procedures. Constant
contact can cause damage
and wear to the trimmer
head.
Sweeping
• The rotating cord‘s
fanning effect can be
used for quick and easy
cleaning. Hold the cord
parallel to and above the
area to be swept and
move the trimmer from
side to side.
• When cutting and
sweeping you should use
full throttle to obtain the
best results.
!
WARNING!
Beware of thrown objects. Always wear eye
protection. Never lean over the guard.
Stones, rubbish etc. can be thrown up into
the eyes resulting in blindness or other
serious injury.
Keep unauthorised persons at a distance.
Children, animals, onlookers and helpers
should be outside the safety zone of 15
meters (50 feet). Stop the machine
immediately if anyone approaches.

Adjusting the harness and clearing
saw
!
WARNING!
When working with the clearing saw it
should always be hooked in the harness.
If this is not done, you cannot control the
clearing saw safely and this can result in
injury to yourself or someone else. Never
use a harness with a defective quick
release catch.
Quick release
On the front is an easily
accessible, quick release
catch. Use this if the engine
should catch fire or in any
other emergency situation
when you quickly need to
take off the harness and
machine.
Even load on the
shoulders
A well-adjusted harness and
clearing saw significantly
facilitates working. Adjust
the harness for the best
working position. Tension
the side straps so that the
weight is evenly distributed
across the shoulders.
Correct height
1) Forestry clearing
Adjust the carrier strap so
that the suspension hook
comes approximately 10
cm under the hip. The
blade should be angled
forward a little.
2)Grass clearing
The suspension hook
should hang
approximately 20 cm
under the hip so that the
blade is parallel to the
ground.
Correct balance
1)Forestry clearing
Move the suspension eye
forwards or backwards. If
the blade is balanced a 1020 cm above the ground it
is easier to avoid stones.
2)Grass clearing
Let the blade balance at a
comfortable clearing
height, i.e. close to the
ground.

FUEL HANDLING
Fuel
Mixture
NOTE!
The machine is fitted with a two-stroke engine and must
always be run on a mixture of petrol and two-stroke oil. It is
important to measure the quantity of oil accurately, to ensure
the correct mixture ratio. Small discrepancies in the amount of
oil have a great bearing on the proportions of the fuel mixture
when mixing small amounts of fuel.
• Always mix petrol and oil in a clean container intended for
petrol.
• Always start by filling half the quantity of petrol required.
Then add the entire oil quantity. Mix (shake) the fuel
mixture. Fill the remaining quantity of petrol.
• Mix (shake) the fuel mixture carefully before filling in the
machine‘s fuel tank.
• Do not mix more than max. one month’s supply of fuel.
• If the machine is not used for a long period of time, the fuel
tank should be emptied and cleaned.
!
WARNING!
Always provide good ventilation when
handling fuel.
Petrol
NOTE!
Always use an oil-mixed
quality petrol (at least 90
octane). If your machine is
equipped with a catalytic
converter, (see “technical
data”) an unleaded, oil
mixed quality petrol should
always be used. A leaded
petrol will destroy the
catalytic converter.
• The lowest recommended
octane rating is 90. If you
run the engine on a petrol
with a lower octane rating
than 90 so-called
“knocking“ can occur.
This leads to an increased
engine temperature, which
can result in a serious
engine breakdown.
• When working at
continuous high revs a
higher octane rating is
recommended.
Two-stroke oil
• For the best results use
HUSQVARNA two-stroke
oil, which has been
specially produced for
clearing saws and chain
saws.
Mixing ratio 1:50 (2%).
• If HUSQVARNA two-stroke oil is not available you can use
a high quality two-stroke oil intended for air cooled engines.
Contact your dealer when selecting an oil.
Mixing ratio: 1:33 (3%).
• Never use two-stroke oil intended for water cooled outboard
motors, so-called outboard motor oil.
• Never use oil intended of four-stroke engines.
22 – English
!
WARNING!
The catalytic converter muffler gets very hot
during and after use. This also applies
during idling. Be aware of the fire hazard,
especially when handling the saw near
flammable substances or vapours.
Fuelling
!
WARNING!
The following precautions reduce the risk
of fire:
Do not smoke or place any sources of heat
in the vicinity of the fuel. Never refuel
when the engine is running. Always stop
the engine and let it cool for a few minutes
before refuelling. Open the fuel cap slowly
when fuelling so that any over pressure is
released slowly. Tighten the fuel cap
carefully after refuelling. Always move the
machine from the fuelling place before
starting.
• Clean around the fuel
cap. Contamination in
the tank can disrupt
operations.
• Ensure that the fuel is
well mixed by shaking the
container before filling
the tank.

START AND STOP
Control before starting
For reasons of safety follow
these recommendations!
• 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 guard is
not damaged or cracked.
Replace the guard if it is
exposed to impact or is
cracked.
• Check that the trimmer
head and spray guard are
not damaged or cracked.
Replace the trimmer head
or spray guard if they are
exposed to impact or are
cracked.
• Never use the machine without a guard or spray guard nor
with a defective guard.
Start and stop
!
WARNING!
The complete clutch cover with shaft must
be fitted before the machine is started,
otherwise the clutch can become loose
and cause personal injury.
Always move the machine from the filling
area before starting. Place the machine on
a flat surface. Ensure the cutting
equipment cannot come into contact with
any object. Make sure no unauthorised
persons are in the working area,
otherwise there is a risk of serious
personal injury. The safety distance is 15
metres.
Cold engine
IGNITION: Set the stop
switch to the start position.
CHOKE: Set the choke

MAINTENANCE
Carburettor
Basic setting
Your Husqvarna product has been designed and
manufactured to specifications that reduce harmful
emissions.
After your unit has been run 8-10 tanks of fuel the engine
has broken in. To ensure that your unit is at peak
performance and producing the least amount of harmful
emissions after break in, have your authorized servicing
dealer, who has a revolution counter at his disposal, to adjust
your carburettor for optimum operating conditions.
• The carburettor is set to its basic setting when test run at the
factory. The basic setting should be kept during the
machine‘s first working hours. Thereafter the carburettor
should be finely adjusted. Fine adjustment should be carried
out by a skilled technician.
!
WARNING!
The complete clutch cover with shaft must
be fitted before the machine is started,
otherwise the clutch can become loose
and cause personal injury.
Functioning
• The carburettor governs
the engine speed via the
throttle trigger. In the
carburettor, air/fuel is
mixed. This air/fuel
mixture is adjustable. If
you want to take
advantage of the
maximum output of the
engine, the setting must be
corret.
• The setting of the
carburettor means that the
engine is adjusted to local
conditions, for example
climate, altitude, petrol
and type of two-stroke oil.
• The carburettor has three
adjustment possibilities:
L= Low speed needle
H= High speed
adjustment screw
T= Idle speed adjustment
screw
• The fuel quantity required in proportion to the airflow the
throttle trigger level allows is adjusted by means of the Land H-needles. Turning the needles clockwise gives a leaner
fuel mixture (less fuel), turning them counter-clockwise gives
a richer fuel mixture (more fuel). A lean mixture gives higher
rpms and a rich one lower rpms.
• The idling speed screw T regulates the position of the
throttle lever in the idling speed position. Turn the idling
speed screw clockwise gives a higher idling speed, turn it
counter-clockwise a lower idling speed.
NOTE! If the cutting attachment rotates/moves in the idling
position, turn the idling speed screw counter-clockwise until
the blade stops.
Rec. idling speed: 2700 rpm.
Recommended max. speed: See “technical data”.
!
WARNING!
Contact your servicing dealer, if the idle
speed setting cannot be adjusted so
that the cutting attachment stops. Do
not use the machine until it has been
properly adjusted or repaired.
Fine adjustment
• When the machine has been ”run-in” the carburettor should
be finely adjusted. The fine adjustment should be carried
out by qualified person. First adjust the L-jet, then the
idling screw T and then the H-jet.
Conditions
• Before any adjustments are made the airfilter should be clean
and the airfilter cover fitted. Adjusting the carburettor while
a dirty airfilter is in use will result in a leaner mixture when
the filter is finally cleaned. This can give rise to serious
engine damage.
• Carefully turn the L and H needle to the mid point between
fully turned in and fully turned out.
• Do not attempt to adjust the needles beyond the stops as
damage can occur.
• Now start the machine according to the starting instructions
and run it warm for 10 minutes.
NOTE! If the cutting attachment rotates/moves the T screw
should be turned anti-clockwise until the cutting attachment
stops.
Low speed needle L
Try to find the highest idling
speed, turning the low speed
needle L clockwise
respectively counterclockwise. When the highest
speed has been found, turn
the low speed needle L 1/4
turn counter-clockwise.
NOTE! If the cutting
attachment rotates/moves in
the idling position, turn the
idling speed screw T
counter-clockwise until the
cutting attachment stops.
+ 1/4

24 – English
MAINTENANCE
Final setting of the idling speed T
Correctly adjusted carburettor
Adjust the idling speed with
the screw T, If it is necessary
to readjust. First turn the
idle speed adjusting screw T
clockwise until the cutting
attachment starts to rotate/
move.
Then turn, counterclockwise until the cutting
attachment stops. A correctly
adjusted idle speed setting
occurs when the engine runs
smoothly in every position.
It should also be good
margin to the rpm when the
cutting attachment starts to
rotate/move.
A correctly adjusted carburettor means that the machine
accelerates without hesitation and the machine 4-cycles a
little at max speed. Furthermore, the cutting attachment
must not rotate/move at idling. A too lean adjusted low
speed needle L may cause starting difficulties and bad
acceleration.
A too lean adjusted high speed needle H gives lower power
= less capacity, bad acceleration and/or damage to the
engine.
A too rich adjustment of the two speed needles L and H
gives acceleration problems or too low working speed.
CAUTION! Contact your servicing dealer, if the idle speed
setting cannot be adjusted so that the cutting attachment
stops. Do not use the machine until it has been properly
adjusted or repaired.
High speed needle H
The high speed needle affects
the machine’s power, speed,
temperature and fuel
consumption. A too lean
adjustment on the high
speed needle H (the high
speed needle H is screwed in
too much) gives a too high
speed resulting in engine
damage. Do not allow the
engine to run at full speed
for more than 10 seconds.
Apply full throttle and turn
the high speed needle H
slowly anticlockwise until
the engine runs unevenly.
The high speed needle H is
then turned slowly clockwise
a little until the engine runs
smoothly.
Note the engine should be
run unloaded when
adjusting the high speed
H
needle. Therefore dismantle
the cutting equipment, nut,
support flange and disc drive
before adjusting the high
speed needle. The high speed
needle is adjusted correctly when the machine ‘splatters’ a little
. If the machine smokes heavily at the same time as it ‘splatters’
heavily the adjustment is too rich.
NOTE! For optimum setting of the carburettor, contact a
qualified servicing dealer who has a revolution counter at his
disposal.

MAINTENANCE
Muffler
Cooling system
NOTE!
Some mufflers are fitted with a catalytic converter. See
“Technical data” to see whether you clearing saw is fitted with a
catalytic converter.
To maintain as low operating temperature as possible
the engine is equipped with
a cooling system.
The muffler is designed to
dampen the noise level and
to direct the exhaust fumes
away from the user. The
exhaust fumes are hot and
can contain sparks, which
can result in fire if the
exhaust fumes are directed
towards a dry and
inflammable material. Some
mufflers are equipped with a
special spark arrest screen. If
your machine is fitted with
this type of screen it should
be cleaned regularly. This is
done using a wire brush. On
mufflers without a catalytic
converter the screen should
be cleaned weekly, or
replaced if necessary. On
mufflers fitted with a
catalytic converter the
screen should be checked
and cleaned monthly. If the
screen is damaged it should
be replaced. If the screen is
frequently blocked, this can
be a sign that the function
of the catalytic converter is
impaired. Contact your
dealer to inspect the muffler.
A blocked screen will cause
the engine to overheat
resulting in damage to the
cylinder and piston. Also see
under “Maintenance”.
The cooling system consists
of:
1. An air intake on the
starter unit.
2. Cooling fins on the
flywheel.
3. Cooling fins on the
cylinder
4. Cylinder cover (leads cold

NOTE!
Never use a machine with a
defective muffler.
!
26 – English
WARNING!
Mufflers fitted with catalytic converters
become extremely hot during use and
after stopping. This also applies at idling
speeds. Contact can result in burns to
the skin. Be observant to the risk of fire!
4
Clean the cooling system
using a brush at least once a
week, in difficult conditions
more often.
A dirty or blocked cooling
system leads to the engine
overheating resulting in
damage to the cylinder and
piston.

MAINTENANCE
Air filter
Spark plug
The air filter should be
cleaned regularly removing
dust and dirt to avoid:
• carburettor malfunction
• starting problems
• reduced engine power
• unnecessary wear to
engine parts
• abnormal fuel
consumption
The condition of the spark
plug is affected by:
• An incorrect carburettor
setting.
• An incorrect fuel mixture
(too much or faulty oil).
• A dirty air filter.
Clean the filter after every
25 hours or more regularly
if operating conditions are
exceptionally dusty.
Cleaning the air filter
Dismantle the air filter cover and remove the air filter. Wash in
clean, warm soapy water. Ensure that the filter is dry before
refitting. An air filter used for a long period of time can never
be cleaned completely. Therefore it is necessary to replace the
filter from time to time with a new filter. A damaged air filter
must always be replaced.
0,5 mm
These factors cause deposits
on the spark plug electrode
that may result in
malfunction or starting
difficulties.
If the machine is low on power, difficult to start or runs
poorly while idling always check the spark plug first.
If the spark plug is dirty, clean it and at the same time check
that the electrode gap is 0.5 mm. The spark plug should be
changed after about one month of operation or earlier if
necessary.
NOTE! Always use the recommended type of spark plug. An
incorrect spark plug can damage the cylinder/piston.
Filing the grass blade
Angle gear
The angle gear is filled
with a sufficient quantity
of grease at the factory.
However, before using the
machine you should check
that the angle gear is filled
to 3/4 with grease. Use
HUSQVARNA special
grease.
Normally, the grease does
not need to be changed
except when the angle gear
is repaired.
Two-part shaft
The end of the drive axle in
the lower shaft should be
lubricated with grease every
30 hours. There is a risk that
the drive axle ends (splined
coupling) on two-part shafts
jam if they are not lubricated
regularly.
!
WARNING!
Always stop the engine before starting
work on any part of the cutting equipment.
This continues to rotate even after the
throttle has been released. Ensure that the
cutting equipment has stopped completely
and remove the cable from the spark plug
before you start to work on it.
• See the cutting
equipment’s packaging
for correct filing
instructions.
• The blades are sharpened
using a single cut flat file.
• Sharpen all edges equally
to maintain the balance
of the blade.
!
WARNING!
Always discard a blade that is bent,
twisted, cracked, shattered or damaged in
any other way. Never attempt to straighten
a twisted blade for use again. Only use
original blades of the prescribed type.

MAINTENANCE
Sharpening the clearing blade
!
WARNING!
Incorrect cutting equipment or an
incorrectly sharpened blade increases
the risk of kickback.
• See the cutting
equipment’s packaging
for correct filing
instructions.
• A correctly sharpened
blade is a prerequisite for
working efficiently and to
avoid unnecessary wear to
the blade and clearing
saw.
• Make sure that the blade
is well supported when
you use the file. Use a 5.5
mm round file with a file
holder.
• The sharpening angle is
15°. Every other tooth is
sharpened to the right
and the intermediate
tooth to the left. When
the blade has been heavily
pitted by stones the upper
side of the teeth can, in
exceptional cases, need to
be dressed using a flat file.
In such cases this takes
place before sharpening
with the round file.
Dressing the top side
must be carried out
equally for all teeth.
• Adjust the setting. This
should be 1 mm.
Maintenance schedule
Below follows some general maintenance instructions.
If you need further information please contact your service
workshop.

7. Check that the guard is
undamaged and not
cracked.
Replace the guard if it
has been exposed to
impact or is cracked.
8. Check that the blade is
well centred, is sharp, and

uncentred blade causes
vibrations that can result
in damage to the
machine.
9. Check that the trimmer
head is undamaged and
not cracked. Replace the
trimmer head if necessary.
10.Check that the locking
nut is tight.
11.Check that the blade‘s
