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:
•
Preheat the intake air to the carburettor 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.

MAINTENANCE
Temperature 0°C 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 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).
