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 Charles 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.

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 correctly and if service and/or repairs are not carried out  
professionally. If you need further information please contact  
your nearest service workshop.  
Check that the throttle control and throttle lock move freely  
and that the return springs work properly.  
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.

GENERAL SAFETY PRECAUTIONS  
Hand guard  
Muffler  
The muffler is designed to keep noise levels to a minimum  
and to direct exhaust fumes away from the user.  
The hand guard prevents hands from coming into contact with  
the moving blades, for example, if the operator loses grip on  
the front handle.  
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.  
Check that the hand guard is fitted correctly.  
Check that the hand guard is undamaged.  
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.  
The machine′s vibration damping system reduces the transfer  
of vibration between the engine unit/cutting equipment and  
the machine′s handle unit.  
Never use a machine that has a faulty muffler.  
The engine body including the blades is suspended on the  
handlebar system via a four springs.  
Regularly check the vibration damping units for cracks or  
deformation. Check that the vibration damping element is  
undamaged and securely attached.  
Regularly check that the muffler is securely attached to the  
machine.  
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.  
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! 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!  
!

GENERAL SAFETY PRECAUTIONS  
Gear housing  
WARNING! The inside of the muffler contain  
chemicals that may be carcinogenic. Avoid  
contact with these elements in the event of a  
damaged muffler.  
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.  
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.  
Replace the blades if they are bent or damaged.  
Blade guard  
The blade guard (A) is intended to protect against any part of  
the body coming into contact with the blades (B).

FUEL HANDLING  
Petrol  
Fuel safety  
Never start the machine:  
1
2
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 on Technical 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.  
•
•
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 and transporting fuel always use approved  
containers intended for this purpose.  
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 working at continuous high revs a higher octane  
rating is recommended.  
•
•
Ensure the machine is cleaned and that a complete  
service is carried out before long-term storage.  
Two-stroke oil  
The transport guard must always be fitted to the cutting  
attachment when the machine is being transported or in  
storage.  
•
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  
CAUTION! The machine is equipped with a two-stroke  
engine and must always been run using a mixture of petrol  
and two-stroke engine 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.  
•
Mixing ratio  
1:50 (2%) with HUSQVARNA two-stroke oil.  
1:33 (3%) with oils class JASO FB or ISO EGB formulated  
for air-cooled, two-stroke engines.

MAINTENANCE  
Carburettor  
Muffler  
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! 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.  
WARNING! The complete clutch cover and  
gear housing must be fitted before the  
machine is started, otherwise the clutch may  
come loose and cause personal injury.  
!
Function  
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 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.  
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. See also instructions  
under the heading Maintenance.  
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.  
Adjusting the idle speed  
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.  
Before any adjustments are made, make sure that the air filter  
is clean and the air filter cover is fitted.  
CAUTION! Never use a machine with a defective muffler.  
Adjust the idle speed with the idle adjustment screw T, if  
adjustment is necessary. First turn the idle adjustment screw  
T 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.  
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 blades must also remain stationary when the choke  
control is in the start throttle position.  
T
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  
Air filter  
To keep the working temperature as low as possible the  
machine is equipped with a cooling system.  
The air filter must be regularly cleaned to remove dust and dirt  
in order to avoid:  
•
•
•
•
•
Carburettor malfunctions  
Starting problems  
Loss of engine power  
1
2
Unnecessary wear to engine parts.  
Excessive fuel consumption.  
3
Clean the filter every 25 hours, or more regularly if conditions  
are exceptionally dusty.  
The cooling system consists of:  
1
2
3
Fins on the flywheel.  
Cooling fins on the cylinder.  
Cylinder cover (directs cold air over the cylinder).  
Cleaning the air filter  
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.  
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.  
Spark plug  
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.  
The spark plug condition is influenced by:  
•
•
Incorrect carburettor adjustment.  
Oiling the air filter  
An incorrect fuel mixture (too much or incorrect type of  
oil).  
•
A dirty 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.  
These factors cause deposits on the spark plug electrodes,  
which may result in operating problems and starting  
difficulties.  
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.  
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 0.7 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.

MAINTENANCE  
Gear housing  
There is a grease nipple on the gearbox. Use a grease gun to  
top up with grease. This should be carried out after  
approximately every 60 working hours. Use Husqvarna  
special grease, No. 503 98 96-01.  
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.  
The grease in the bevel gear does not normally need to be  
changed except if repairs are carried out.  
Cleaning and lubrication  
Clean any resin and plant residue from the blades using  
cleaning agent 531 00 75-13 (UL22) before and after using  
the machine.  
Lubricate the blade bars with special grease, part no. 531 00  
75-12 (UL 21) before long periods of storage.
