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).
When lubricating, remove the clutch cover by loosening
the bar nut. 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 with a screwdriver. Turning the screw
clockwise will increase the oil flow, turning it anticlockwise
will reduce the oil flow.
The oil tank should become nearly empty by time fuel is
used up. Be sure to refill the oil tank every time when
refueling the saw.
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 Clutch cover
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.
Winter use
Running problems can occur when using the machine in
the cold and snowy conditions caused by:
• Too low engine temperature.
• Icing of the air filter and carburetor.
Special measures are therefore often required:
• Partly mask the air inlet on the starter to increase the
working temperature of the engine.
!
WARNING! The engine must be stopped
when making adjustments.
