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 carburettor 
space.

CAUTION! When the winter plug is fitted the winter flap 
must be open!

Heated handles

(357 XPG, 359 G)

On models with the designation XPG/G, the front as well 
as the rear handle are equipped with electric heating 
coils. These are supplied with electricity from a built-in 
generator on the chain saw.

When the switch is pushed downwards, the heat is 
switched on. When the switch is pushed upwards, the 
heat is switched off.

Electrical carburettor heating

(357 XPG, 359 G)

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.

IMPORTANT! If the temperature rises above -5

°

C or 0

°

respectively the machine MUST be restored to its 
normal set-up. Otherwise there is a risk of overheating, 
which can cause severe engine damage.
