Lubricate the bar tip sprocket each time you refuel. Use 
the special grease gun and a good quality bearing grease.

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 grease being squirted into the centre 
of the crankshaft using a grease gun.

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 middle position. 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": Minimum flow

Bar 16”-18”:  Medium flow

Bar 20"-28":  Maximum flow

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.
