The clutch drum has a needle bearing on the output shaft. 
This needle bearing must be lubricated regularly (once a 
week). CAUTION! Use only high quality bearing grease or 
engine oil. See instructions under the heading Cutting 
equipment.

The oil pump is adjustable. Adjustments are made by 
turning the screw using a screwdriver or combination 
spanner. The machine is supplied from the factory set to 
1 turn open. 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.
