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 Karl 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.
Thank you for using a Husqvarna product.
Husqvarna AB has a policy of continuous product development and therefore reserves the right to modify the design and
appearance of products without prior notice.

GENERAL SAFETY PRECAUTIONS
Use of incorrectly wound cord or an incorrect cutting
attachment increases the level of vibration. See
instructions under the heading Cutting equipment.
Stop switch
Use the stop switch to switch off the engine.
The machine′s vibration damping system reduces the
transfer of vibration between the engine unit/cutting
equipment and the machine′s handle unit.
Regularly check the vibration damping units for cracks or
deformation. Check that the vibration damping element is
undamaged and securely attached.
Start the engine and make sure the engine stops when
you move the stop switch to the stop setting.
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.These 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.
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.
Muffler
Check that the guard is undamaged and not cracked.
Replace the guard if it has been exposed to impact or is
cracked.
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.
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.
Vibration damping system
Your machine is equipped with a vibration damping
system that is designed to minimize vibration and make
operation easier.
For mufflers it is very important that you follow the
instructions on checking, maintaining and servicing your
machine.

GENERAL SAFETY PRECAUTIONS
Never use a machine that has a faulty muffler.
•
Extend the life of cutting equipment.
IMPORTANT!
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.
Regularly check that the muffler is securely attached to
the machine.
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.
If the muffler on your machine is fitted with a spark
arrestor mesh this must be cleaned regularly. A blocked
mesh will cause the engine to overheat and may lead to
serious damage.
WARNING! A faulty cutting attachment
may increase the risk of accidents.
!
Trimmer head
IMPORTANT!
Always ensure the trimmer cord is wound tightly and
evenly around the drum, otherwise the machine will
generate harmful vibration.
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.
!
•
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.
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.
!
•
•
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.
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!
The length of the cord is also important. A longer cord
requires greater engine power than a shorter cord of
the same diameter.
Cutting equipment
This section describes how to choose and maintain your
cutting equipment in order to:
•
•
Make sure that the cutter on the trimmer guard is
intact.This is used to cut the cord to the correct length.
•
•
Reduce the risk of blade thrust.
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.
Obtain maximum cutting performance.

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 onTechnical 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.
•
•
When storing and transporting fuel always use
approved containers intended for this purpose.
•
•
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 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.
•
•
Ensure the machine is cleaned and that a complete
service is carried out before long-term storage.
When working at continuous high revs a higher octane
rating is recommended.
The transport guard must always be fitted to the
cutting attachment when the machine is being
transported or in storage.
Two-stroke oil
•
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.
•
For best results and performance use HUSQVARNA
two-stroke engine oil, which is specially formulated for
our air-cooled two-stroke engines.
•
Never use two-stroke oil intended for water-cooled
engines, sometimes referred to as outboard oil (rated
TCW).
WARNING!Take care when handling fuel.
Bear in mind the risk of fire, explosion
and inhaling fumes.
•
•
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.
Fuel
•
Mixing ratio
CAUTION! The machine is equipped with a two-stroke
engine and must always been run using a mixture of
petrol and two-stroke 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.

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.
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.

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.
•
When cutting and sweeping you should use full
throttle to obtain the best results.
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.

The T-screw regulates the throttle setting at idle
Carburettor
speed. If the T-screw is turned clockwise this gives a
higher idle speed; turning it anti-clockwise gives a
lower idle speed.
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.
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.
WARNING! The complete clutch cover
and shaft must be fitted before the

from the machine.
stops, contact your dealer/service
workshop. Do not use the machine until
it has been correctly adjusted or
repaired.
•
•
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.
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.
The carburettor has three adjustment controls:
L = Low speed jet
H = High speed jet
Conditions
T = Idle adjustment screw
•
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.
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.

MAINTENANCE
Low speed jet L
High speed jet H
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 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.
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.
Fine adjustment of the idle speedT
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.
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.
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
CAUTION! For optimum adjustment of the carburettor,
contact a qualified dealer/service workshop that has a
revolution counter at their disposal.
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.
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.

Muffler
Cooling system
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.
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
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.
The cooling system consists of:
1

Air intake on the starter.
Fins on the flywheel.
Cooling fins on the cylinder.
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:
CAUTION! Never use a machine with a defective muffler.
•
•
Incorrect carburettor adjustment.
An incorrect fuel mixture (too much or incorrect type
of oil).
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.
•
A dirty air filter.
These factors cause deposits on the spark plug
electrodes, which may result in operating problems and
starting difficulties.
Remember the risk of fire!

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.
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.
Two-piece shaft
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 drive shaft end in the lower shaft should be lubricated
with grease every 30 hours. There is a risk that the drive
shaft ends (splined coupling) on models with two-piece
shafts will seize if they are not lubricated regularly.
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.
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.

MAINTENANCE
Bevel gear
The bevel gear is filled with the right quantity of grease at
the factory. However, before using the machine you
should check that the bevel gear is filled three-quarters
full with grease. Use HUSQVARNA special grease.
The grease in the bevel gear does not normally need to
be changed except if repairs are carried out.
