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).
Both versions have a needle bearing on the drive shaft,
which has to be greased regularly (once a week).
NOTE! Use a high-quality bearing grease or engine oil.
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.
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.
WARNING! The engine must not be
running when making adjustments.
