If the chainsaw is low on power, difficult to start or runs 
poorly at idle speed, always check the spark plug first before 
taking any further action. If the spark plug is dirty, clean it 
and check that the electrode gap is 0.7mm (0.028 inches). 
The spark plug should be replaced after about a month of 
operation or earlier if necessary.

Lubricating the bar tip sprocket

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

Needle bearing lubrication

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 Cutting equipment.

Adjustment of the oil pump

The oil pump is adjustable. Adjustments are made by turning 
the screw using a screwdriver or combination spanner. The 
chainsaw 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:

Bar 22” -24”:  3 turns from the closed position.

Cooling system

To keep the working temperature as low as possible the 
chainsaw 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 chainsaw overheating, which causes 
damage to the piston and cylinder.

“Air Injection” centrifugal cleaning

Centrifugal cleaning means the following: 

• 

All air to the carburettor passes through the starter.

• 

Dirt and dust is pushed out by the cooling fan.

MAINTENANCE

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.

WARNING! The engine must be stopped when 
making adjustments.

NOTE: The cooling system on a chainsaw with a catalytic 
converter must be cleaned daily. This is particularly 
important on chainsaws with catalytic converters as 
the higher exhaust temperature requires efficient 
cooling of the engine and the catalytic converter unit.

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.
