Turbo Air Cleaning" Centrifugal Cleaning; Winter Use; Heated Handles - Jonsered CS 2171 WH Operator's Manual

"Turbo Air Cleaning" 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

During cold weather and under powder snow conditions,
operating problems can arise due to:
• 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.

Heated handles

(CS 2171WH)
On models with the designation W, 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.

MAINTENANCE
Electrical carburetor heating
(CS 2171WH)
Canada
If this chain saw has the model code WH/CWH 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.
