The clutch drum has a needle bearing on the output shaft. 
This needle bearing must be lubricated regularly (once a 
week).

When lubricating, remove the clutch cover by loosening the 
two bar nuts. Lay the saw on its side with the clutch drum 
upwards.

Lubrication involves engine oil dripping into the centre of the 
clutch drum as it rotates.

 

Adjustments are made by turning the screw using a 
screwdriver or combination spanner. The machine is supplied 
from the factory with the screw set to position 2. Turning the 
screw clockwise will reduce the oil flow and turning the screw 
anti-clockwise will increase the oil flow.

Recommended settings:

These recommendations apply to Husqvarna’s chain oil, for 
other chain oils increase the oil flow by one step.

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

Air guide plate.

3

Fins on the flywheel.

4

Cooling fins on the cylinder.

5

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.

Centrifugal cleaning means the following: All air to the 
carburetor passes through the starter. Dirt and dust is pushed 
out by the cooling fan.

IMPORTANT! In order to maintain operation of the centrifugal 
cleaning system it must be regularly maintained. Clean the air 
intake to the starter, the fins on the flywheel, the space around 
the flywheel, inlet pipe and carburetor compartment.
