SAFETY INSTRUCTIONS
Vibration damping system
Your machine is equipped with a vibration damping system
that is designed to minimize vibration and make operation
easier.
Use of incorrectly wound cord or an incorrect cutting
attachment increases the level of vibration.
The machine ′ s vibration damping system reduces the transfer
of vibration between the engine unit/cutting equipment and
the machine ′ s handle unit.
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 colour 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. See
instructions under the heading Checking, maintaining and
servicing the machine’s safety equipment.
WARNING! Mufflers fitted with catalytic
converters 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!
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!
Cutting equipment
A trimmer head is intended for trimming grass.
Muffler
The muffler is designed to keep noise levels to a minimum
and to direct exhaust fumes away from the user.
A muffler fitted with a catalytic converter is also designed to
reduce harmful exhaust gases.
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.
Locking nut
A locking nut is used to secure some types of cutting
attachment.

• Never use a machine that has a faulty muffler.
English
SAFETY INSTRUCTIONS
• Regularly check that the muffler is securely attached to
the machine.
• If the muffler on your machine is fitted with a spark
arrestor mesh then it should be cleaned regularly. A
blocked mesh causes the engine to overheat, which can
lead to serious damage. Never use a muffler with a
defective spark arrestor mesh.
Cutting equipment
This section describes how to choose and maintain your
cutting equipment in order to:
• Obtain maximum cutting performance.
• Extend the life of cutting equipment.
General rules
1 Only use cutting attachments with the guards we
recommend! See the chapter on Technical data.
• Tighten the nut using the socket spanner. 35-50 Nm (3.55 kpm).
CAUTION! 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.
WARNING! Never use a machine with faulty
safety equipment. The machine’s safety
!
equipment must be checked and maintained
as described in this section. If your machine
fails any of these checks contact your
service agent to get it repaired.
Cutting equipment
IMPORTANT!
This section describes how to choose and maintain your
cutting equipment in order to:
Reduce the risk of blade thrust.
Obtain maximum cutting performance.
Extend the life of cutting equipment.
Only use cutting attachments with the guards we
recommend! See the chapter on Technical data.
Refer to the instructions for the cutting attachment to check
the correct way to load the cord and the correct cord
diameter.
2 Check the cutting attachment for damage or cracks. A
damaged cutting attachment should always be replaced.
Locking nut
• 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.)
Trimmer head
• Only use the recommended trimmer heads and trimmer
cords. These have been tested by the manufacturer to suit
a particular engine size. This is especially important when
a fully automatic trimmer head is used. Only use the
recommended cutting attachment. See the chapter on
Technical data.
• Smaller machines generally require small trimmer heads
and vice versa. This is because when clearing using a
cord the engine must throw out the cord radially from the
trimmer head and overcome the resistance of the grass
being cleared.
• The length of the cord is also important. A longer cord
requires greater engine power than a shorter cord of the
same diameter.
• Make sure that the cutter on the trimmer guard is intact.
This is used to cut the cord to the correct length.
English
– 7
SAFETY INSTRUCTIONS
• To increase the life of the cord it can be soaked in water
for a couple of days. This will make the line tougher so that
it lasts longer.
IMPORTANT! Always ensure the trimmer cord is wound
tightly and evenly around the drum, otherwise the machine
will generate harmful vibration.
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.

General working instructions
IMPORTANT!
This section describes the basic safety precautions for
working with clearing saws and trimmers.
If you encounter a situation where you are uncertain how to
proceed you should ask an expert. Contact your dealer or
your service workshop.
Avoid all usage which you consider to be beyond your
capability.
You must understand the difference between forestry
clearing, grass clearing and grass trimming before use.
Basic safety rules
• Never start the machine:
1 If you have spilt fuel on it. Wipe off the spillage and
allow remaining fuel to evaporate.
2 If you have spilt 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.
4 Avoid all skin contact with fuel. Fuel is a skin irritant
and may even cause skin changes.
Transport and storage
• Store and transport the machine and fuel so that there is
no risk of any leakage or fumes coming into contact with
sparks or naked flames, for example, from electrical
machinery, electric motors, electrical relays/switches or
boilers.
• When storing and transporting fuel always use approved
containers intended for this purpose.
• When storing the machine for long periods the fuel tank
must be emptied. Contact your local petrol station to find
out where to dispose of excess fuel.
• The transport guard must always be fitted to the cutting
attachment when the machine is being transported or in
storage.
1 Look around you:
• To ensure that people, animals or other things cannot
affect your control of the machine.
• To ensure that people, animals, etc., do not come into
contact with the cutting attachment or loose objects that
are thrown out by the cutting attachment.
• CAUTION! Do not use the machine unless you are able to
call for help in the event of an accident.
2 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.
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
unless you have it in clear sight.

SAFETY INSTRUCTIONS
Basic working techniques
• 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 using a trimmer head and plastic blades
Trimming
• Hold the trimmer head just above the ground at an angle.
It is the end of the cord that does the work. Let the cord
work at its own pace. Never press the cord into the area
to be cut.
Cutting
• The trimmer is ideal for cutting grass that is difficult to
reach using a normal lawn mower. Keep the cord parallel
to the ground when cutting. Avoid pressing the trimmer
head against the ground as this can ruin the lawn and
damage the tool.
• Do not allow the trimmer head to constantly come into
contact with the ground during normal cutting. Constant
contact of this type can cause damage and wear to the
trimmer head.
Sweeping
• The fan effect of the rotating cord can be used for quick
and easy clearing up. Hold the cord parallel to and above
the area to be swept and move the tool to and fro.
• The cord can easily remove grass and weeds up against
walls, fences, trees and borders, however it can also
damage sensitive bark on trees and bushes, and damage
fence posts.
• Reduce the risk of damaging plants by shortening the
cord to 10-12 cm and reducing the engine speed.
Clearing
• The clearing technique removes all unwanted vegetation.
Keep the trimmer head just above the ground and tilt it. Let
the end of the cord strike the ground around trees, posts,
statues and the like. CAUTION! This technique increases
the wear on the cord.
• The cord wears quicker and must be fed forward more
often when working against stones, brick, concrete, metal
fences, etc., than when coming into contact with trees and
wooden fences.
• When trimming and clearing you should use less than full
throttle so that the cord lasts longer and to reduce the
wear on the trimmer head.
• 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 blade is rotating, as this can
result in serious injury. Stop the engine and
blade before you remove material that has
wound around the blade shaft as otherwise
there is a risk of injury. The bevel gear can
get hot during use and may remain so for a
while afterwards. You could get burnt if you
touch it.
WARNING! Watch out for thrown objects.
Always wear 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.

FUEL HANDLING
Fuel
CAUTION! The machine is equipped with a two-stroke engine
and must always been run using a mixture of petrol and twostroke engine oil. It is important to accurately measure the
amount of oil to be mixed to ensure that the correct mixture is
obtained. When mixing small amounts of fuel, even small
inaccuracies can drastically affect the ratio of the mixture.
WARNING! Always ensure there is adequate
ventilation when handling fuel.
!
Petrol
CAUTION! Always use a good quality petrol/oil mixture (at
least 90 octane). If your machine is equipped with a catalytic
converter (see chapter on Technical data) always use a good
quality unleaded petrol/oil mixture. Leaded petrol will destroy
the catalytic converter and it will no longer serve its purpose.
Use low-emission petrol, also known as alkylate petrol, if it is
available.
Mixing
• Always mix the petrol and oil in a clean container intended
for fuel.
• Always start by filling half the amount of the petrol to be
used. Then add the entire amount of oil. Mix (shake) the
fuel mixture. Add the remaining amount of petrol.
• Mix (shake) the fuel mixture thoroughly before filling the
machine’s fuel tank.
• Do not mix more than one month’s supply of fuel at a time.
• If the machine is not used for some time the fuel tank
should be emptied and cleaned.
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 working near
flammable substances and/or vapours.
• The lowest recommended octane rating is 90. If you run
the engine on a petrol with a lower octane rating than 90
this can cause knocking. This leads to an increased
engine temperature, which can result in serious engine
damage.
• When working at continuous high revs a higher octane
rating is recommended.
Two-stroke oil
• For best results and performance use HUSQVARNA twostroke oil, which is specially formulated for our two-stroke
engines. Mixture 1:50 (2%).
• 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%).
• Never use two-stroke oil intended for water-cooled
outboard engines, sometimes referred to as outboard oil.
• Never use oil intended for four-stroke engines.

Carburettor
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 minimise harmful exhaust emissions
after the running-in period, ask your dealer/service workshop
(who will have a rev counter at their disposal) to adjust your
carburettor.
WARNING! The complete clutch cover and
shaft must be fitted before the machine is
!
started, otherwise the clutch can come loose
and cause personal injury.
Function
• The carburettor governs the engine’s speed via the
throttle control. Air and fuel are mixed in the carburettor.
The air/fuel mixture is adjustable. Correct adjustment is
essential to get the best performance from the machine.
• Adjusting the carburettor means that the engine is
adapted to local operating conditions, e.g. climate,
altitude, petrol and the type of 2-stroke oil.
• The carburettor has three adjustment controls:
L = Low speed jet
H = High speed jet
T = Idle adjustment screw
WARNING! If the idle speed cannot be
adjusted so that the cutting attachment
!
stops, contact your dealer/service
workshop. Do not use the machine until it
has been correctly 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 a qualified person. First adjust the L-jet,
then the idling screw T and then the H-jet.
Conditions
• Before any adjustments are made, make sure that the air
filter is clean and the air filter cover is fitted. If you adjust
the carburettor when the air filter is dirty it will result in a
leaner mixture when the filter is finally cleaned. This can
lead to serious engine damage.
• Carefully turn both jets, L and H, so that they are midway
between fully screwed in and fully screwed out.
• Do not attempt to adjust the L and H jets beyond either
stop as this could cause damage.
• Now start the machine according to the starting
instructions and let it warm up for 10 minutes.
Low speed jet L
Try to find the highest idle speed by turning the low speed jet
L clockwise then anti-clockwise. When the highest speed has
been found, turn the low speed jet L 1/4 turn anti-clockwise.
• The L and H-jets are used to adjust the supply of fuel to
match the rate that air is admitted, which is controlled with
the throttle. If they are screwed clockwise the air/fuel ratio
becomes leaner (less fuel) and if they are turned anticlockwise the ratio becomes richer (more fuel). A lean
mixture gives a higher engine speed and a rich mixture
gives a lower engine speed.
• 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 anti-clockwise gives a lower idle speed.
Basic setting
• The basic carburettor settings are adjusted during testing
at the factory. The basic setting is richer than the optimal
setting and should be maintained for the first few hours the
machine is in use. The carburettor should then be finely
adjusted. 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 anticlockwise until the cutting attachment stops.
Rec. idle speed 2700 rpm
Recommended max. speed: See the Technical data section.
CAUTION! If the cutting attachment rotates when the engine
is idling the idle adjustment screw T should be turned anticlockwise 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 anticlockwise 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.
WARNING! If the idle speed cannot be adjusted so that the
cutting attachment stops, contact your dealer/service
workshop. Do not use the machine until it has been correctly
adjusted or repaired.

MAINTENANCE
High speed jet H
The high speed jet H affects the engine power, speed,
temperature and fuel consumption. If the high speed jet H is
set too lean (screwed in too far) the engine speed will be too
high and cause engine damage. Do not let the engine run at
full speed for more than 10 seconds.
Apply full throttle and turn the high speed jet H very slowly
clockwise until the engine slows down. Then turn the high
speed jet H very slowly anticlockwise until the engine starts to
run unevenly. Now turn the high speed jet H slowly clockwise
a little way until the engine runs smoothly.
Note that the engine should not be under load when you
adjust the high speed jet H. You should therefore remove the
cutting attachment, nut, support flange and drive disc before
adjusting the high speed jet H.
The high speed jet H is adjusted correctly when the machine
burbles a little. If the machine races then the setting is too
lean. If the engine produces a lot of smoke and burbles a lot
then the setting is too rich.
H
Muffler
CAUTION! Some mufflers are fitted with a catalytic converter.
See chapter on Technical data to see whether your machine
is fitted with a catalytic converter.
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.
Some mufflers are equipped with a special spark arrestor
mesh. If your machine has this type of muffler, you should
clean the mesh at least once a week. This is best done with a
wire brush. On mufflers without a catalytic converter the mesh
should be cleaned weekly, or replaced if necessary. On
mufflers fitted with a catalytic converter the mesh should be
checked, and if necessary cleaned, monthly. If the mesh is
damaged it should be replaced.
If the mesh is frequently blocked, this can be a sign that the
performance of the catalytic converter is impaired. Contact
your dealer to inspect the muffler. A blocked mesh will cause
the machine to overheat and result in damage to the cylinder
and piston.
CAUTION! For optimum adjustment of the carburettor,
contact a qualified dealer/service workshop that has a
revolution counter at their disposal.
Correctly adjusted carburettor
When the carburettor is correctly adjusted the machine will
accelerate without hesitation and burble a little at maximum
speed. It is also important that the cutting attachment does
not rotate at idle. If the low speed jet L is set too lean it may
cause starting difficulties and poor acceleration.
If the high speed jet H is set too lean it will result in less power,
less performance, poor acceleration and/or damage to the
engine.
If both the L and H jets are set too rich it will results in
acceleration problems or too low a working speed.
CAUTION! Never use a machine with a defective muffler.
WARNING! Mufflers fitted with catalytic
converters 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!

MAINTENANCE
Cooling system
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
4
3
2
1
The cooling system consists of:
1 Air intake on the starter.
2 Fins on the flywheel.
3 Cooling fins on the cylinder.
4 Cylinder cover (directs cold air over the cylinder).
Clean the cooling system with a brush once a week, more
often in demanding conditions. A dirty or blocked cooling
system results in the machine overheating which causes
damage to the piston and cylinder.
Spark plug
The spark plug condition is influenced by:
• Incorrect carburettor adjustment.
• An incorrect fuel mixture (too much or incorrect type of
oil).
• 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 0.5 mm. The spark plug should be
replaced after about a month in operation or earlier if
necessary.
Air filter
The air filter must be regularly cleaned to remove dust and dirt
in order to avoid:
• Carburettor malfunctions
• Starting problems
• Loss of engine power
• Unnecessary wear to engine parts.
• 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. 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.
If the machine is used in dusty conditions the air filter should
be soaked in oil. See instructions under the heading Oiling the
air filter.
Oiling the air filter
Always use HUSQVARNA filter oil, art. no. 531 00 92-48. The
filter oil contains a solvent to make it spread evenly through
the filter. You should therefore avoid skin contact.
Put the filter in a plastic bag and pour the filter oil over it.
Knead the plastic bag to distribute the oil. Squeeze the
excess oil out of the filter inside the plastic bag and pour off
the excess before fitting the filter to the machine. Never use
common engine oil. This would drain through the filter quite
quickly and collect in the bottom.
CAUTION! Always use the recommended spark plug type!
Use of the wrong spark plug can damage the piston/cylinder.
Check that the spark plug is fitted with a suppressor.
