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.

Make sure the throttle control is locked at the idle setting
when the throttle lockout is released.
Machine′s safety equipment
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

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 of incorrectly wound cord or an incorrect cutting
attachment increases the level of vibration. See
instructions under the heading Cutting equipment.
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.
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.
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.
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.

GENERAL SAFETY PRECAUTIONS
mesh will cause the engine to overheat and may lead to
serious damage.
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.
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!
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.
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!
For mufflers it is very important that you follow the
instructions on checking, maintaining and servicing your
machine.
Locking nut
Never use a machine that has a faulty muffler.
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

GENERAL SAFETY PRECAUTIONS
The nylon lining inside the locking nut must not be so worn
Trimmer head
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.
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:
•
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.
•
•
•
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.
•
•
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! 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.
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.
WARNING! A faulty cutting attachment
may increase the risk of accidents.

WORKING TECHNIQUES
Cutting
Basic working techniques
•
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.
!
Grass trimming with a trimmer head
•
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

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.
quick and easy clearing up. Hold the cord parallel to
and above the area to be swept and move the tool to
and fro.
•
•
The cord can easily remove grass and weeds up
against walls, fences, trees and borders, however it
can also damage sensitive bark on trees and bushes,
and damage fence posts.
Reduce the risk of damaging plants by shortening the
cord to 10-12 cm and reducing the engine speed.
•
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.

MAINTENANCE
Muffler
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.
!
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)
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.
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.
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
2
3
4
Air intake on the starter.
Fins on the flywheel.
The air filter must be regularly cleaned to remove dust
and dirt in order to avoid:
Cooling fins on the cylinder.
Cylinder cover (directs cold air over the cylinder).
•
•
•
•
•
Carburettor malfunctions
Starting problems
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.
Loss of engine power
Unnecessary wear to engine parts.
Excessive fuel consumption.
Spark plug
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.
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.
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.
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.
