MAINTENANCE
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.
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.
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 (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.
Note: The machine should only be run for short periods at its 
highest 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 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.
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.
CAUTION!  Never use a machine with a defective muffler.
Cooling system
To keep the working temperature as low as possible the 
machine is equipped with a cooling system.
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.
!
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.
!
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.

!
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!
