MAINTENANCE
36 – English
clean it and check that the electrode gap is 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.
For recommended spark plug, see Technical data.
Needle bearing lubrication
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 grease being squirted into the centre
of the crankshaft using a grease gun.
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:
Bar 13"-15": Minimum flow
Bar 16”-18”: Medium flow
Bar -20": Maximum flow
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.
!
WARNING! The engine must not be
running when making adjustments.
