MAINTENANCE
Spark plug
Adjustment of the oil pump
The spark plug condition is influenced by:
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 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.
CAUTION! Max. 1 1/2 turns.
•
•
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 0.5 mm (0,020"). The spark plug
should be replaced after about a month in operation or earlier
if necessary.
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.
Lubricating the bar tip sprocket
The cooling system consists of:
1
2
3
4
5
Air intake on the starter.
Air guide plate.
Lubricate the bar tip sprocket each time you refuel. Use the
special grease gun and a good quality bearing grease.
Fins on the flywheel.
Cooling fins on the cylinder.
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.
