”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:
• Preheat the intake air to the carburetor by using the heat
from the cylinder.
• Partly mask the air inlet on the starter to increase the
working temperature of the engine.
Fitting the winterising kit
Cut out a hole using a knife as shown.
Fit the winter cover in the cylinder cover.
Temperature 0°°
°°
C (32°°
°°
F) or colder:
Move the cover from position A to position B so that
preheated air from the cylinder can pass into the carburettor
compartment and prevent, e.g. the air filter icing up again.
When fitting the winter cover in position B the centrifugal
cleaning nozzle is blocked. This measure requires the air
filter to be cleaned more regularly.
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.
IMPORTANT! Any maintenance other than that described in
this manual must be carried out by your servicing dealer
(retailer).
