"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.

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 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
heat from the cylinder.
Temperature 0°C or colder
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.
Move the plug from position 1 to position 2 so that the
preheated air from the cylinder can pass into the

MAINTENANCE
carburettor space and prevent ice from forming on the air
filter. Lift off the air filter to obtain better access.
For temperatures below -5°C and/or in snow conditions a
special cover is available, which is mounted on the starter
housing.
Part number: 580 65 98-01.
These reduce the flow of cooling air and prevent large
amounts of snow from being sucked into the carburettor
space.
IMPORTANT! 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

543 XPG
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.
When the switch is pushed upwards, the heat is switched
on. When the switch is pushed downwards, the heat is
switched off.
