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 waterpowered 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
CLOTHING
Wear clothes made of a strong fabric and avoid loose
clothing that can catch on twigs and branches. Always
wear heavy, long pants. Do not wear jewellery, shorts
sandals or go barefoot. Secure hair so it is above shoulder
level.
the throttle control is automatically locked at the idle
setting.
FIRST AID KIT
Always have a first aid kit nearby.
Machine′s safety equipment
Make sure the throttle control is locked at the idle setting
when the throttle lockout is released.
This section describes the machine′s safety equipment,
its purpose, and how checks and maintenance should be
carried out to ensure that it operates correctly. See the
”What is what?” section to locate where this equipment is
positioned on your machine.
The life span of the machine can be reduced and the risk
of accidents can increase if machine maintenance is not

carried out professionally. If you need further information
please contact your nearest service workshop.
Press the throttle lockout and make sure it returns to its
original position when you release it.
IMPORTANT!
All servicing and repair work on the machine requires
special training. This is especially true of the machine′s
safety equipment. If your machine fails any of the
checks described below you must contact your service
agent. When you buy any of our products we guarantee
the availability of professional repairs and service. If the
retailer who sells your machine is not a servicing dealer,
ask him for the address of your nearest service agent.
!
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.
Throttle lockout
The throttle lockout is designed to prevent accidental
operation of the throttle control. When you press the lock
(A) (i.e. when you grasp the handle) it releases the throttle
control (B). When you release the handle the throttle
control and the throttle lockout both move back to their
original positions. This movement is controlled by two
independent return springs. This arrangement means that
Check that the throttle control and throttle lockout move
freely and that the return springs work properly.
See instructions under the heading Start. Start the
machine and apply full throttle. Release the throttle and
check that the cutting attachment stops and remains at a
standstill. If the cutting attachment rotates with the throttle
in the idle position then the carburettor idle setting must
English – 7
GENERAL SAFETY PRECAUTIONS
be checked. See instructions under the heading
Maintenance.
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.
Use of incorrectly wound cord or an incorrect cutting
attachment increases the level of vibration. See
instructions under the heading Cutting equipment.
The machine′s vibration damping system reduces the
transfer of vibration between the engine unit/cutting
equipment and the machine′s handle unit.
Start the engine and make sure the engine stops when
you move the stop switch to the stop setting.
Cutting attachment guard
Regularly check the vibration damping units for cracks or
deformation. 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.
Check that the guard is undamaged and not cracked.
Replace the guard if it has been exposed to impact or is
cracked.
Always use the recommended guard for the cutting
attachment you are using. See chapter on Technical data.
!
8 – English
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.
!
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.
GENERAL SAFETY PRECAUTIONS
Muffler
mesh will cause the engine to overheat and may lead to
serious damage.
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.
!
!
For mufflers it is very important that you follow the
instructions on checking, maintaining and servicing your
machine.
Never use a machine that has a faulty 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!
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:
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
A locking nut is used to secure some types of cutting
attachment.
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.)
Regularly check that the muffler is securely attached to
the machine.
When loosening and tightening the saw blade nut, there
is a risk of injury from the teeth of the saw blade. You
should therefore always ensure that your hand is shielded
by the blade guard when doing this. Always use a socket
spanner with a shaft that is long enough to allow this. The
arrow in the diagram shows the area where you should
operate the socket spanner when loosening or tightening
the nut.
If the muffler on your machine is fitted with a spark
arrestor mesh this must be cleaned regularly. A blocked
English – 9
GENERAL SAFETY PRECAUTIONS
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.
Trimmer head
IMPORTANT!
Always ensure the trimmer cord is wound tightly and
evenly around the drum, otherwise the machine will
generate harmful vibration.
Cutting equipment
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 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.
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.
!
!
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.
WARNING! A faulty cutting attachment
may increase the risk of accidents.

FUEL HANDLING
Fuel handling
Petrol
Never start the machine:
Always use an unleaded quality petrol of at least 90
octane (RON).
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.
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.
Use low-emission petrol, also known as alkylate petrol, if
it is available.
•
The lowest recommended octane grade 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 and increased bearing load,
which can result in serious engine damage.
•
When working at continuous high revs a higher octane
rating is recommended.
•
If the machine is not used for some time the fuel tank
should be emptied and cleaned.
Engine oil
•
When storing and transporting fuel always use
approved containers intended for this purpose.
Check the oil level before starting the machine. A too low
oil level can cause serious damage to the engine.
•
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 the machine is new the engine oil should be
changed after the first month or after 10 hours of
operation.
•
The transport guard must always be fitted to the
cutting attachment when the machine is being
transported or in storage.
•
For the best result and function use HUSQVARNA
engine oil.
•
•
Secure the machine during transport.
•
Ensure the machine is cleaned and that a complete
service is carried out before long-term storage.
When HUSQVARNA engine oil is not available
another high grade engine oil can be used. Contact
your dealer when selecting oil. Engine oil for fourstroke petrol engines must be used. Quality class at
least API SG. In general viscosity class SAE 10W-40
is recommended.
•
Never use oil intended for two-stroke engines.
!
WARNING! Take care when handling fuel.
Bear in mind the risk of fire, explosion
and inhaling fumes.
Oil level
The machine must be switched off and placed on a flat
surface when you check the oil level.
Fuel
Unscrew the oil cap, clean the dipstick located on the cap
and insert the cap again without screwing it down. Check
the oil level on the dipstick.
CAUTION! The machine is equipped with a four-stroke
engine. Make sure that there is always sufficient oil in the
oil tank.
!
!
WARNING! Fuel and fuel fumes are
highly inflammable and can cause
serious injury when inhaled or allowed to
come in contact with the skin. For this
reason observe caution when handling
fuel and make sure there is adequate
ventilation.
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.
English – 13
FUEL HANDLING
When the oil level is low, top up using engine oil to the
edge of the oil refill hole.
Only use recommended engine oil.
Fuelling
!
WARNING! Taking the following
precautions, will lessen the risk of fire:
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.
When refuelling, open the fuel cap slowly
so that any excess pressure is released
gently.
Tighten the fuel cap carefully after
refuelling.
Always move the machine away from the
refuelling area before starting.
Clean around the fuel cap. Clean the fuel and oil tank
regularly. The fuel filter should be changed at least once
a year. Contamination in the tanks causes malfunction.
Always move the machine about 3 metres from the
refuelling position before starting.

You must understand the difference between forestry
clearing, grass clearing and grass trimming before use.
Basic safety rules
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
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.
3
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.
4
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! 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.
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.
!
WARNING! Watch out for thrown objects.
Always wear approved eye protection.

WORKING TECHNIQUES
Basic working techniques
Cutting
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.
•
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.
!
WARNING! Sometimes branches or
grass get caught between the guard and
cutting attachment. Always stop the
engine before cleaning.
Grass trimming with a trimmer head
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.
•
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.
18 – English
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
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.
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.
Function
•
The carburettor governs the engine’s speed via the
throttle control. Air and fuel are mixed in the
carburettor.
•
Setting the carburettor involves adapting the engine to
suit local conditions, e.g. climate, altitude and the
petrol.
Basic setting
The basic carburettor settings are adjusted during testing
at the factory.
CAUTION! For optimum adjustment of the carburettor,
contact a qualified dealer/service workshop that has a
revolution counter at their disposal.
Adjusting the idle speed (T)
Check that the air filter is clean. When the idle speed is
correct, the cutting attachment should not rotate. If
adjustment is required, close (turn clockwise) the idle
adjustment screw T, with the engine running, until the
cutting attachment starts to rotate. Open (turn
anticlockwise) the screw until the cutting attachment
stops. The idle speed is correctly set when the engine
runs smoothly in all positions, and there is a clear margin
to the speed at which the cutting attachment starts to
rotate.
The muffler on your machine is equipped with a spark
arrestor mesh, this should be cleaned regularly. A blocked
mesh will cause the engine to overheat and may lead to
serious damage.
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!
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
Cooling system
Two-piece shaft
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
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.
Air filter
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 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.
The spark plug condition is influenced by:
•
Incorrect carburettor adjustment.
•
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 0,6-0,7 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.
20 – English
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.
MAINTENANCE
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.
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.
