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 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.

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.

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