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.
Recommended settings:
Less oil with short bar and/or soft wood.
More oil with longer bar and/or hard wood.
WARNING! The engine must be stopped
when making adjustments.

Cooling system
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.
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
The cooling system consists of:
Lubricating the bar tip sprocket

Air intake on the starter.
Air guide plate.
Fins on the flywheel.
Cooling fins on the cylinder.
Cylinder cover (directs cold air over the cylinder).
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
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.
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
