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

fi

lter and carburetor.

Special measures are therefore often required:

•

Preheat the intake air to the carburetor 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 (32

°°°°

F) 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

fi

lter icing up again.

When

fi

tting the winter cover in position B the centrifugal

cleaning nozzle is blocked. This measure requires the air

fi

lter

to be cleaned more regularly.

Temperature -5

°°°°

C (23

°°°°

F) or colder:

For running the machine in cold weather or powder snow, a
special cover is available, which is mounted on the starter
housing. This reduces the intake of cold air and prevents large
amounts of snow from being sucked in.

CAUTION! If the special winterising kit has been

fi

tted or any

measures have been taken to increase the temperature these
changes must be reversed before the machine is used in
normal temperature conditions. Otherwise there is a risk of
overheating, resulting in severe damage to the engine.

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

Heated handles

575XPG

On models with the model code XPG both the front handle
bar and the rear handle are equipped with electrical heating
coils. These are supplied with electricity from a generator built
into the chain saw.

Electrical carburetor heating

575XPG

If this chain saw has the model code XPG then it is equipped
with an electrically heated carburettor. The electrical heating
prevents icing in the carburettor. A thermostat regulates
heating so that the carburettor always has the correct working
temperature.
