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
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.
