INTRODUCTION
Dear Customer,
Congratulations on your choice to buy a Husqvarna product! Husqvarna is based on a tradition that dates back to 1689, when the
Swedish King Charles XI ordered the construction of a factory on the banks of the Husqvarna River, for production of muskets.The
location was logical, since water power was harnessed from the Huskvarna River to create the water-powered plant. During the
more than 300 years of beeing, the Husqvarna factory has produced a lot of different products, from wood stoves to modern kitchen
appliances, sewing machines, bicycles, motorcycles etc. In 1956, the first motor driven lawn mowers appeared, followed by chain
saws in 1959, and it is within this area Husqvarna is working today.
Today Husqvarna is one of the leading manufacturers in the world of forest and garden products, with quality as our highest priority.
The business concept is to develop, manufacture and market motor driven products for forestry and gardening as well as for
building and construction industry. Husqvarna′s aim is also to be in the front edge according to ergonomics, usability, security and
environmental protection. That is the reason why we have developed many different features to provide our products within these
areas.
We are convinced that you will appreciate with great satisfaction the quality and performance of our product for a very long time to
come. The purchase of one of our products gives you access to professional help with repairs and service whenever this may be
necessary. If the retailer who sells your machine is not one of our authorised dealers, ask for the address of your nearest service
workshop.
It is our wish that you will be satisfied with your product and that it will be your companion for a long time. Think of this operator′s
manual as a valuable document.By following its′ content (using, service, maintenance etc) the life span and the second-hand value
of the machine can be extended. If you will sell this machine, make sure that the buyer will get the operator′s manual.

GENERAL SAFETY PRECAUTIONS
Check that the vibration damping element is undamaged and
securely attached.
Cutting attachment guard
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
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.
!
condition.These symptoms normally appear
in the fingers, hands or wrists.The risk
increases at low temperatures.
Check that the guard is undamaged and not cracked.Replace
the guard if it has been exposed to impact or is cracked.
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.
Always use the recommended guard for the cutting
attachment you are using. See chapter on Technical data.
WARNING! Never use a cutting attachment
without an approved guard. See the chapter
on Technical data. If an incorrect or faulty
guard is fitted this can cause serious
personal injury.
!
Vibration damping system
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.
Your machine is equipped with a vibration damping system
that is designed to minimize vibration and make operation
easier.
Using incorrectly wound cord or a blunt or incorrect cutting
attachment (wrong type or incorrectly filed, see instructions
under the heading Filing the blade) increases the level of
vibration.
For mufflers it is very important that you follow the instructions
on checking, maintaining and servicing your machine.
The machine′s vibration damping system reduces the transfer
of vibration between the engine unit/cutting equipment and
the machine′s handle unit.
Never use a machine that has a faulty muffler.
Regularly check the vibration damping units for cracks or
deformation.
Regularly check that the muffler is securely attached to the
machine.

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.
WARNING! Bear in mind that:
!
!
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!
Locking nut
WARNING! Using an incorrect cutting
attachment or an incorrectly sharpened
blade increases the risk of kickback.
!
A locking nut is used to secure some types of cutting
attachment.
Cutting equipment
Grass blades and grass cutters are intended for cutting
coarse grass.
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.
A trimmer head is intended for trimming grass.
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.

GENERAL SAFETY PRECAUTIONS
General rules
Trimmer head
IMPORTANT!
Always ensure the trimmer cord is wound tightly and evenly
around the drum, otherwise the machine will generate
harmful vibration.
Only use cutting attachments with the guards we
recommend! See the chapter on Technical data.
•
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.
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.
•
•
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.
Check the cutting attachment for damage or cracks. A
damaged cutting attachment should always be replaced.
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.
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.
Sharpening grass cutters and grass
blades
•
•
See the cutting attachment packaging for correct
sharpening instructions. Sharpen blades and cutters
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, 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.

2
If you have spilt fuel on it. Wipe off the spillage and allow
remaining fuel to evaporate.
CAUTION! Always use a quality petrol/oil mixture at least 90
octane (RON). 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.
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.
Use low-emission petrol, also known as alkylate petrol, if it is
available.
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.
•
•
The lowest octane recommended is 90 (RON). If you run
the engine on a lower octane grade than 90 so-called
knocking can occur. This gives rise to a high engine
temperature, which can result in serious engine damage.
•
•
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.
When working at continuous high revs a higher octane
rating is recommended.
•
•
Ensure the machine is cleaned and that a complete
service is carried out before long-term storage.
Two-stroke oil
The transport guard must always be fitted to the cutting
attachment when the machine is being transported or in
storage.
•
For best results and performance use HUSQVARNA two-
stroke engine oil, which is specially formulated for our air-
cooled two-stroke engines.
•
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.
•
Never use two-stroke oil intended for water-cooled
engines, sometimes referred to as outboard oil (rated
TCW).
•
•
Never use oil intended for four-stroke engines.
A poor oil quality and/or too high oil/fuel ratio may
jeopardise function and decrease the life time of catalytic
converters.
WARNING! Take care when handling fuel.
Bear in mind the risk of fire, explosion and
inhaling fumes.
!
•
Mixing ratio
1:50 (2%) with HUSQVARNA two-stroke oil.
Fuel
1:33 (3%) with oils class JASO FB or ISO EGB formulated
for air-cooled, two-stroke engines.
CAUTION! The machine is equipped with a two-stroke
engine and must always been run using a mixture of petrol
and two-stroke 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.

FUEL HANDLING
Mixing
Fuelling
•
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.
WARNING!Taking the following precautions,
will lessen the risk of fire:
•
Mix (shake) the fuel mixture thoroughly before filling the
machine’s fuel tank.
!
Do not smoke or place hot objects near fuel.
Always shut off the engine before refuelling.
Always stop the engine and let it cool for a
few minutes before refuelling.

STARTING AND STOPPING
Check before starting
Starting and stopping
•
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 cover and
shaft must be fitted before the machine is
started, otherwise the clutch can come loose
and cause personal injury.
!
Always move the machine away from the
refuelling area before starting. Place the

running or the cutting equipment is rotating,
as this can result in serious injury.
!
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.
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 burnt if you touch
it.
Basic safety rules
1
•
Look around you:
To ensure that people, animals or other things cannot
affect your control of the machine.
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.
!
•
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.
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
•
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.
around without first checking behind you to
make sure no-one is within the safety zone.
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.
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.
!
WARNING! Avoid cutting with the area of the
blade between the 12 o’clock and 3 o’clock
positions. Because of the speed of rotation
of the blade kickback can occur if you
attempt to cut thick stems with this area of
the blade.
4
5
Keep a good balance and a firm foothold.
!
Always hold the machine with both hands. Hold the
machine on the right side of your body.

WORKING TECHNIQUES
Clearing
Grass clearing using a grass blade
•
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.
•
Grass blades and grass cutters must not be used on
woody stems.
•
•
A grass blade is used for all types of tall or coarse grass.
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.
•
•
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.
Cutting
•
•
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.
Try to work rhythmically. Stand firmly with your feet apart.
Move forward after the return stroke and stand firmly
again.
•
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.
•
•
Let the support cup rest lightly against the ground. It is
used to protect the blade from hitting the ground.
Reduce the risk of material wrapping around the blade by
following these instructions:
1
2
Always work at full throttle.
Avoid the previously cut material during the return
stroke.
•
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.
•
Stop the engine, unclip the harness and place the
machine on the ground before you start to collect the cut
material.
Sweeping
Grass trimming with a trimmer head
•
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.
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.
•
When cutting and sweeping you should use full throttle to
obtain the best results.
•
•
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.

MAINTENANCE
Basic setting
Carburettor
•
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.
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.
CAUTION! If the cutting attachment rotates when the engine
is idling the idle adjustment screw T should be turned anti-
clockwise until the cutting attachment stops.
WARNING! The complete clutch cover and
shaft must be fitted before the machine is
started, otherwise the clutch can come loose
Rec. idle speed See the Technical data section.

Recommended max. speed: See theTechnical data section.
and cause personal injury.
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.
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.
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.
•
•
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.
Conditions
The carburettor has three adjustment controls:
L = Low speed jet
•
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.
H = High speed jet
T = Idle adjustment screw
•
•
•
Carefully turn both jets, L and H, so that they are midway
between fully screwed in and fully screwed out.
L
Do not attempt to adjust the L and H jets beyond either
stop as this could cause damage.
H
Now start the machine according to the starting
instructions and let it warm up for 10 minutes.
T
CAUTION! If the cutting attachment rotates when the
engine is idling the idle adjustment screw T should be
turned anti-clockwise until the cutting attachment stops.
•
•
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 anti-
clockwise the ratio becomes richer (more fuel). A lean
mixture gives a higher engine speed and a rich mixture
gives a lower engine speed.
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 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.
L
CAUTION! If the cutting attachment rotates when the engine
is idling the idle adjustment screw T should be turned anti-
clockwise until the cutting attachment stops.

MAINTENANCE
Fine adjustment of the idle speedT
Correctly adjusted carburettor
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.
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.
T
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.
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.
!
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.
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.
H
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.
Note that the engine should be loaded when you adjust the
high speed jet H.You should therefore fit the trimmer head
T35 (2.7 mm cord) before adjusting the high speed jet. The
cord length should be standard, i.e.to the knife on the trimmer
guard.
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.
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!
H
!
CAUTION! For optimum adjustment of the carburettor,
contact a qualified dealer/service workshop that has a
revolution counter at their disposal.

MAINTENANCE
Cooling system
Air filter
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
The air filter must be regularly cleaned to remove dust and dirt
in order to avoid:
•
•
•
•
•
Carburettor malfunctions
Starting problems
3
2
Loss of engine power
Unnecessary wear to engine parts.
Excessive fuel consumption.
1
The cooling system consists of:
1
2
3
Air intake on the starter.
Cooling fins on the cylinder.
Cylinder cover (directs cold air over the cylinder).
Clean the filter every 25 hours, or more regularly if conditions
are exceptionally dusty.
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.
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.
Bevel gear
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.
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.
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
The grease in the bevel gear does not normally need to be
changed except if repairs are carried out.
Always use special filter oil. 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.

MAINTENANCE
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.
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.
