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 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.
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.
