MAINTENANCE
”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 centrifugal
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
working temperature of the engine.
Temperature 0
°°°°C or colder:
The cylinder cover is designed so it can be adjusted for
running in cold weather. Twist the winter flap so that
preheated air from the cylinder can pass into the carburettor
space preventing icing of the air filter, etc.
For temperatures below -5 °C and/or in snow conditions there
is also:
• a special cover (A) for the starter housing
• a winter plug (B) for the air nozzle that is fitted as shown.
These reduce the flow of cooling air and prevent large
amounts of snow from being sucked into the carburettor
space.
CAUTION! When the winter plug is fitted the winter flap must
be open!

IMPORTANT! If the temperature rises above -5 °C or 0°C
respectively the machine MUST be restored to its normal
set-up. Otherwise there is a risk of overheating, which can
cause severe engine damage.
