MAINTENANCE
”Air Injection” centrifugal cleaning
Centrifugal cleaning means the following: All air to the
carburettor passes through the starter. Dirt and dust is
centrifuged 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 carburettor
compartment.
Heated handles
(362XPG, 372XPG)
On models with the model code XPG/G 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.
When the red mark on the switch is visible, the heating is on.
Electrical carburettor heating
(362XPG, 372XPG)
This machine is equipped with an electronically controlled
carburettor heater.
Applications
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.
Winter use
During cold weather and under powder snow conditions,
operating problems can arise due to:
• 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.
Temperature -5°C 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.
IMPORTANT! Any maintenance other than that described
in this manual must be carried out by your servicing dealer
(retailer).
