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, so that preheated air from the
cylinder can pass into the carburettor space preventing icing
of the air filter, etc.
Temperature -5°°
°°
C 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.
IMPORTANT! Any maintenance other than that described in
this manual must be carried out by your servicing dealer
(retailer).
