MAINTENANCE

Heated handles

(CS 2171W)

On models with the model code W, 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

(CS 2171WH)

Canada

If this chain saw has the model code WH 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.

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.

IMPORTANT!

Any maintenance other than that described in this manual must be carried out by your servicing dealer (retailer).
