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.
• Preheat the intake air to the carburettor by using the
heat from the cylinder.
Temperature 5°°
°°
C or colder:
The air filter holder is prepared so it can be changed for
use in the cold. Remove the air filter cover and air filter.
Turn the winter cover anticlockwise using a screwdriver so
that the preheated air from the engine can pass inside the
carburettor compartment and prevent, for example, the air
filter from icing up (see figure).
For temperatures below 5°C and/or in snow conditions
there is also:
• a special cover for the starter housing
These reduce the cooling air and prevent large amounts
of snow from being sucked into the engine.
IMPORTANT! The machine MUST be returned to its
standard design at temperatures warmer than 5
°C .
Otherwise there is a risk of overheating resulting in
serious engine damage.
