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).
