The clutch drum is fitted with one of the following drive 
sprockets:

•

A   Spur sprocket (the chain sprocket is welded on the 
drum)

•

B   Rim sprocket (replaceable)

Both versions have a needle bearing on the drive shaft, which 
has to be greased regularly (once a week).

CAUTION! Use only high quality bearing grease or engine oil.

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 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:

Bar 13"-15": Position 1

Bar 15"-18": Position 2

Bar 18"-20": Position 3

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 
carburettor passes through the starter. Dirt and dust is 
centrifuged 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 carburettor 
compartment.
