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.

Vibration damping system
Your machine is equipped with a vibration damping
system that is designed to minimize vibration and make
operation easier.
Stop switch
Use the stop switch to switch off the engine.
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.
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.
Start the engine and make sure the engine stops when
you move the stop switch to the stop setting.
Cutting attachment guard
Check that the vibration damping element is undamaged
and securely attached.
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.
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.
Check that the guard is undamaged and not cracked.
Replace the guard if it has been exposed to impact or is
cracked.
Muffler
Always use the recommended guard for the cutting
attachment you are using. See chapter on Technical data.

thread.) Tighten the nut using the socket spanner.
General rules
Only use cutting attachments with the guards we
recommend! See the chapter on Technical data.
The nylon lining inside the locking nut must not be so worn
that you can turn it by hand. The lining should offer a
resistance of at least 1.5 Nm.The nut should be replaced
after it has been put on approx. 10 times.
Cutting equipment
This section describes how to choose and maintain your
cutting equipment in order to:
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.
•
•
•
Reduce the risk of blade thrust.
Obtain maximum cutting performance.
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.
Check the cutting attachment for damage or cracks. A
damaged cutting attachment should always be replaced.
Keep the teeth of the blade correctly sharpened! Follow
our recommendations. Also refer to the instructions on
the blade packaging.
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.
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.
WARNING! Using an incorrect cutting
attachment or an incorrectly sharpened
blade increases the risk of blade thrust.
!
Cutting equipment
Grass blades and grass cutters are intended for cutting
coarse grass.

GENERAL SAFETY PRECAUTIONS
•
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.
!
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 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.
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.

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
•
•
Secure the machine during transport.
•
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.
WARNING!Take care when handling fuel.
Bear in mind the risk of fire, explosion
and inhaling fumes.
A poor oil quality and/or too high oil/fuel ratio may
jeopardise function and decrease the life time of
catalytic converters.
!
•
Mixing ratio
Fuel
1:50 (2%) with HUSQVARNA two-stroke oil.
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.

General working instructions
IMPORTANT!
This section describes the basic safety precautions for
working with brush cutters 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

Keep the cutting attachment below waist level.
1
•
Look around you:
Switch off the engine before moving to another area.
Fit the transport guard before carrying or transporting
the equipment any distance.
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.
9
Never put the machine down with the engine running
unless you have it in clear sight.
•
CAUTION! Do not use the machine unless you are
able to call for help in the event of an accident.
WARNING! Neither the operator of the
machine nor anyone else may attempt to
remove the cut material while the engine
is running or the cutting equipment is
rotating, as this can result in serious
injury.
!
2
Inspect the working area. Remove all loose objects,
such as stones, broken glass, nails, steel wire, string,
etc. that could be thrown out or become wrapped
around the cutting attachment.
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.
3
4
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.
Make sure you can move and stand safely. Check the
area around you for possible obstacles (roots, rocks,
branches, ditches, etc.) in case you have to move
suddenly. Take great care when working on sloping
ground.
WARNING! Watch out for thrown objects.
Always wear approved eye protection.
Never lean over the cutting attachment
guard. Stones, rubbish, etc. can be
thrown up into the eyes causing
blindness or serious injury.
!
Keep unauthorised persons at a
distance. Children, animals, onlookers
and helpers should be kept outside the
safety zone of 15 m. Stop the machine
immediately if anyone approaches. Never
swing the machine around without first
checking behind you to make sure no-
one is within the safety zone.
5
Keep a good balance and a firm foothold.

WORKING TECHNIQUES
•
Let the support cup rest lightly against the ground. It
is used to protect the blade from hitting the 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.
•
Reduce the risk of material wrapping around the blade
by following these instructions:
1Always work at full throttle.
WARNING! Sometimes branches or
grass get caught between the guard and
cutting attachment. Always stop the
engine before cleaning.
2Avoid the previously cut material during the return
stroke.
!
•
Stop the engine, unclip the harness and place the
machine on the ground before you start to collect the
cut material.
WARNING! Machines fitted with saw
blades or grass blades can be thrown

violently to the side when the blade
comes into contact with a fixed object.
This is called blade thrust. A blade thrust
can be violent enough to cause the
machine and/or operator to be propelled
in any direction, and possibly lose
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.
control of the machine. Blade thrust can
occur without warning if the machine
snags, stalls or binds. Blade thrust is
more likely to occur in areas where it is
difficult to see the material being cut.
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, blade thrust can
occur if you attempt to cut thick stems
with this area of the blade.
•
•
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.
Grass clearing using a grass blade
Reduce the risk of damaging plants by shortening the
cord to 10-12 cm and reducing the engine speed.
Clearing
•
•
•
Grass blades and grass cutters must not be used on
woody stems.
•
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.
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.
•
•
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.
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.
Try to work rhythmically. Stand firmly with your feet
apart. Move forward after the return stroke and stand
firmly again.

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

MAINTENANCE
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.
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.
Adjustment of the idle speed
Before any adjustments are made, make sure that the air
filter is clean and the air filter cover is fitted.
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.
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.
T
•
•
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
Rec. idle speed: See the Technical data section.
T = Idle adjustment screw
WARNING! If the idle speed cannot be
adjusted so that the cutting attachment
L
!
stops, contact your dealer/service
workshop. Do not use the machine until
it has been correctly adjusted or
repaired.
H
T
Muffler
•
•
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.
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
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.

MAINTENANCE
cause fire if directed against dry and combustible
material.
Cooling system
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
3
2
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
2
3
Air intake on the starter.
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.
Bevel gear
The bevel gear is filled with the right quantity of grease at
the factory. However, before using the machine you
should check that the bevel gear is filled three-quarters
full with grease. Use HUSQVARNA special grease.
CAUTION! 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!
The grease in the bevel gear does not normally need to
be changed except if repairs are carried out.
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

MAINTENANCE
•
•
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 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.
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.

MAINTENANCE
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.
