Winter use
Running problems can occur when using the machine in the
cold and snowy conditions caused by:
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.

•
Preheat the intake air to the carburetor by using the heat
from the cylinder.

The cylinder cover is designed so it can be adjusted for
running in cold weather. Twist the winter flap so that
preheated air from the cylinder can pass into the carburetor
space preventing icing of the air filter, etc.

conditions there is also:
•
a special cover (A) for the starter housing
•
a winter plug (B) for the air nozzle that is fitted as shown.
These reduce the flow of cooling air and prevent large
amounts of snow from being sucked into the carburetor
space.

Electrical carburetor heating
(346XPG, 353G)
On models with the designation CARBURETOR HEATING
there is an electrically heated carburetor. Electrically powered
heating prevents ice formation in the carburetor. A thermostat
regulates the heating so that the carburetor always has the
right working temperature.
