MAINTENANCE
36 – English
Adjustment of the oil pump.
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 position 2.
Turning the screw clockwise will reduce the oil flow and
turning the screw anti-clockwise will increase the oil flow.
Recommended settings:
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.
”Air Injection” centrifugal
cleaning
Centrifugal cleaning means the following: All air to the
carburettor passes through the starter. Dirt and dust is
centrifuged out by the cooling fan.
IMPORTANT! In order to maintain operation of the
centr
ifugal cleaning system it must be regularly
maintained. Clean the air intake to the starter, the fins on
the flywheel, the space around the flywheel, inlet pipe and
carburettor compartment.
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 carburettor.
Special measures are therefore often required:
• Partly mask the air inlet on the starter to increase the
w
orking temperature of the engine.
Temperature 0°°

C or colder:
The cylinder cover is designed so it can be adjusted for
running in cold weather, so that preheated air from the
cylinder can pass into the carburettor space preventing
icing of the air filter, etc.
