MAINTENANCE

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:

•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.

Temperature 0°C (32°F) 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 (23°F) and/or in snow conditions there is also:

•a special cover for the starter housing

•a cover for cylinder cover’s air inlet should be fitted as illustrated.

These reduce the cooling air and prevent large amounts of snow from being sucked into the engine.

IMPORTANT! If the temperature rises above -5°C (23°F) or 0°C (32°F) respectively the machine MUST be restored to its normal set-up. Otherwise there is a risk of overheating, which can cause severe engine damage.
