MAINTENANCE
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:
•Preheat the intake air to the carburetor by using the heat from the cylinder.
•Partly mask the air inlet on the starter to increase the working temperature of the engine.
Fitting the winterising kit
Cut out a hole using a knife as shown.
Fit the winter cover in the cylinder cover.

Temperature 0°C (32°F) or colder:
Move the cover from position A to position B so that preheated air from the cylinder can pass into the carburettor compartment and prevent, e.g. the air filter icing up again. When fitting the winter cover in position B the centrifugal cleaning nozzle is blocked. This measure requires the air filter to be cleaned more regularly.
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.
IMPORTANT! Any maintenance other than that described in this manual must be carried out by your servicing dealer (retailer).
Heated handles
576XPG
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.
Electrical carburetor heating
576XPG
If this chain saw has the model code XPG 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.
