IMPORTANT! In order to maintain operation of the
centrifugal cleaning system it must be regularly
maintained. Clean the air intake to the starter, the fins on
the flywheel, the space around the flywheel, inlet pipe and
carburettor compartment.

Winter use
Running problems can occur when using the machine in
the cold and snowy conditions caused by:
the cold and snowy conditions caused by:
•
Too low engine temperature.
•
Icing of the air filter and carburettor.
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 carburettor by using the

The intermediate wall is designed so it can be adjusted for
running in cold weather, so that preheated air from the
cylinder can pass into the carburettor space preventing
icing of the air filter, etc. Lift off the air filter to obtain better
access. Use a screwdriver to carefully knock away the
plug in the partition.

Electrical carburettor heating
560XPG, 562XPG
On models with the designation XPG there is an
electrically heated carburettor. Electrically powered
heating prevents ice formation in the carburettor. A
thermostat regulates the heating so that the carburettor
always has the right working temperature.

IMPORTANT! If the temperature rises above -5
°C or 0°C
respectively, the starter housing cover MUST be
removed and the accompanying plug, art. no. 503 40

there is a risk of overheating, resulting in severe
damage to the engine.
