MAINTENANCE
”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.
