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). 
(111)

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.

Centrifugal cleaning means the following: All air to the 
carburetor passes through the starter. Dirt and dust is 
centrifuged out by the cooling fan. (112)

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.

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.

°°°°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. 
(113)

NB! 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.

IMPORTANT! Any maintenance other than that described 
in this manual must be carried out by your servicing 
dealer (retailer).
