should be replaced after about a month in operation or 
earlier if necessary.

Note! Always use the recommended spark plug type! Use of 
the wrong spark plug can damage the piston/cylinder. Check 
that the spark plug is fitted with a suppressor.

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

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.

Note! The cooling system on a chain saw with catalytic 
converter must be cleaned daily. This is particularly 
important on chain saws with catalytic converters, because 
the higher exhaust temperature requires efficient cooling of 
the engine and the catalytic converter unit.
