Spark plug
The spark plug condition is influenced by:
Incorrect carburetor adjustment.
An incorrect fuel mixture (too much or incorrect type 
of oil).
A dirty air filter.
These factors cause deposits on the spark plug 
electrodes, which may result in operating problems and 
starting difficulties.
If the machine 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 0.020 inch (0.5 
mm). The spark plug 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.
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.
Adjustment of the oil pump
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:
Less oil with short bar and/or soft wood.
More oil with longer bar and/or hard wood.
Cooling system
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.
!
WARNING! The engine must be stopped 
when making adjustments.
