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.
?Air Injection? centrifugal cleaning
Adjustment of the oil pumpCentrifugal cleaning means the following: All air to the
carburettor passes through the starter. Dirt and dust is
centrifuged out by the cooling fan.
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 �ow and
turning the screw anti-clockwise will increase the oil �ow.
IMPORTANT! In order to maintain operation of the centrifugal
cleaning system it must be regularly maintained.
? Clean the air intake to the starter, the Ţns on the �ywheel,
the space around the �ywheel, inlet pipe and carburettor
compartment.
