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.

GENERAL SAFETY PRECAUTIONS
Regularly check the vibration damping units for cracks or
deformation. Check that the vibration damping element is
undamaged and securely attached.
Stop switch
Use the stop switch to switch off the engine.
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.
Start the engine and make sure the engine stops when
you move the stop switch to the stop setting.
Muffler
Hand guard
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.
The hand guard prevents hands from coming into contact
with the moving blades, for example, if the operator loses
grip on the front handle.
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.
Check that the hand guard is fitted correctly.
Check that the hand guard is undamaged.
Vibration damping system
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.
Your machine is equipped with a vibration damping
system that is designed to minimize vibration and make
operation easier.
The machine′s vibration damping system reduces the
transfer of vibration between the engine unit/cutting
equipment and the machine′s handle unit. The engine
body including the blades is suspended on the handlebar
system via a four springs.
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.
When the blades are correctly adjusted the play between
the blades should be 0,2–0,4 mm, measured at the
screws.
The edges of the blades are too hard to be filed. Dull
blades should be sharpened using a grinder.
Check that the blades are undamaged and show no signs
of cracking or other damage.
Blade guard
Regularly check that the muffler is securely attached to
the machine.
The blade guard (A) is intended to protect against any
part of the body coming into contact with the blades (B).
A
WARNING! Mufflers fitted with catalytic
converters and exhaust pipes get very
!
hot during use and remain so for some
time after stopping.This also applies
when idling. Contact can result in burns
to the skin. Remember the risk of fire!
B
Check that the blade guard is not damaged or distorted.
Replace the blade guard if it is bent or damaged.
WARNING! The inside of the muffler
contain chemicals that may be
!
carcinogenic. Avoid contact with these
elements in the event of a damaged
muffler.
Gear
The gear housing gets hot when the machine has been in
use. To avoid burning yourself do not touch the gear
housing.
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!
Blades
To ensure good cutting results it is important that the
contact pressure between the blades is correct. The
contact pressure is adjusted by turning the screws on the
underside of the bar clockwise as far as they will go.Then
turn the screws anticlockwise a 1/4 turn. Lock the screws
using the locking nut on the top of the bar. Check that the
screws are loose enough to allow the washers under the
screw heads to slide sideways.

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.

MAINTENANCE
the optimal setting and should be maintained for the
Carburettor
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 blades move while the engine is idling
the T screw should be turned anti-clockwise until they
stop.
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.
Function
Adjust the idle speed with the idle adjustment screw T, if
adjustment is necessary. First turn the idle adjustment
screwT clockwise until the blades start to move.Then turn
the idle adjustment screw T anticlockwise until the blades
stop.The idle speed is correctly adjusted when the engine
runs smoothly in every position. There should also be a
clear margin to the speed at which the blades start to
move. The blades must also remain stationary when the
choke control is in the start throttle position.
•
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.
•
•
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
T = Idle adjustment screw
Rec. idle speed: See the Technical data section.
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 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.
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 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.
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

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

Air intake on the starter.
Fins on the flywheel.
Cooling fins on the cylinder.
Cylinder cover (directs cold air over the cylinder).
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.
CAUTION! Never use a machine with a defective muffler
or exhaust pipe.
The spark plug condition is influenced by:
•
•
Incorrect carburettor adjustment.
An incorrect fuel mixture (too much or incorrect type of
oil).
WARNING! Mufflers fitted with catalytic
converters and exhaust pipes get very
!
hot during use and remain so for some
time after stopping.This also applies
when idling. Contact can result in burns
to the skin. Remember the risk of fire!
•
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.

MAINTENANCE
CAUTION! Always use the recommended spark plug
use common engine oil.This would drain through the filter
quite quickly and collect in the bottom.
type! Use of the wrong spark plug can damage the piston/
cylinder. Check that the spark plug is fitted with a
suppressor.
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
There is a grease nipple and a plug for filling lubricant on
the gear housing. Use a grease gun to fill with grease.
This should be done after every 60 working hours. Use
Husqvarna’s special grease, no. 503 98 96-01.
Unnecessary wear to engine parts.
Excessive fuel consumption.
Clean the filter every 25 hours, or more regularly if
conditions are exceptionally dusty.
CAUTION! The gear housing must not be filled
completely with grease. The grease expands as the
machine heats up during operation. If the gear housing
was completely filled with grease it could damage the
seals and lead to leakage of grease.
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.
The grease in the bevel gear does not normally need to
be changed except if repairs are carried out.
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.
Cleaning and lubrication
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.
Clean any resin and plant residue from the blades using
cleaning agent 531 00 75-13 (UL22) before and after
using the machine.
Oiling the air filter
Lubricate the blade bars with special grease, part no. 531
00 75-12 (UL 21) before long periods of storage.
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
