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
carburetor passes through the starter. Dirt and dust is pushed
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 carburetor 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 carburetor.
Special measures are therefore often required:
•
Partly mask the air inlet on the starter to increase the
working temperature of the engine.

MAINTENANCE
Temperature -5° ° ° ° C (23° ° ° ° F) or colder:
For running the machine in cold weather or powder snow, a
special cover is available, which is mounted on the starter
housing. This reduces the intake of cold air and prevents large
amounts of snow from being sucked in.
CAUTION! If the special winterising kit has been fitted or any
measures have been taken to increase the temperature these
changes must be reversed before the machine is used in
normal temperature conditions. Otherwise there is a risk of
overheating, resulting in severe damage to the engine.
