MAINTENANCE
English – 37
”Air Injection” centrifugal
cleaning
Centrifugal cleaning means the following: All air to the
carburetor passes through the starter. Dirt and dust is
pushed out by the cooling fan.
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
carburetor compartment.
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.
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 fitted 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.
Heated handles
(372XPG)
On models with the designation XPG/G, the front as well
as the rear handle are equipped with electric heating
coils. These are fed with electrical current from an
integrated generator in the chain saw.
When the red mark on the switch is visible, the heating is
on.
Electrical carburetor heating
(372XPG)
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.
Canada
If this chain saw has the model code XPG/G 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.
Other countries
The carburettor heater is used in the following
temperature range:
±0ºC or colder. During high humidity,
icing of the carburettor can occur earlier than specified.
The carburettor heater only heats the carburettor when
the 3-way switch is set to position ”II”.
The switch is off in position ”0”, supplies current to the
handle heater in position ”I”, supplies current to the
carburettor in position ”II”.
CAUTION! The carburettor heater reaches maximum
temperature after about 3 minutes. It is therefore
important that the machine is not run for longer with the
heater switched on. If the switch is left on for too long the
carburettor will overheat and lead to running problems or
starting problems.
