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:

Twist the cover so that preheated air from the cylinder can enter the carburettor space to prevent icing of the air ﬁlter, etc., then ﬁt the rubber seal to the fuel pipe by the main air intake.

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.

IMPORTANT! Any maintenance other than that described in this manual must be carried out by your servicing dealer (retailer).
