Cooling system

To obtain the lowest possible running temperature the saw is
equipped with a cooling
system.The cooling system
consists of:
1. Air intake on the starter
unit.
2. Air guide plate.
3. Fan blades on the
flywheel.
4. Cooling fins on the
cylinder.
5. Cylinder cowling
(supplies cold air over
the cylinder).
Clean the cooling system with a brush once a week, more often
in demanding conditions. A dirty or blocked cooling system
results in the saw overheating which causes damage to
piston and cylinder.

Centrifugal cleaning "Turbo"

Centrifugal cleaning means
the following:
All air to the carburetor is
carried through the starter.
Dirt and dust is centrifuged
away by the cooling fan.
IMPORTANT! In order to
keep the function of the
centrifugal cleaning, a
continous maintenance and
care must be made.
• Clean the air intake to the
starter, the fan wings of the
flywheel, the space around
the flywheel, inlet pipe and
carburetor space.

Heated handles
(CS 2163 W/CS 2171 W)
Both the front handle and the
rear handle are equipped with
electrical heating coils. These
are supplied with electricity
both from a built-in generator
in the electrical system. The
switch for the heating coils is
placed below the stop switch.
When the red marking is
visible, the heating is on.
Electrically heated carburettor
(CS 2163 WH/CS 2171 WH)
Canada
This chain saw is, if it has model code WH, equipped with
electrically heated carburettor. The electrical heating prevents
icing in the carburettor. A thermostat regulates heating so that
the carburettor always has the correct temperature.
All other countries
This chain saw is, if it has model code WH, equipped with
electrically regulated carburettor heating. The carburettor
heating system is regulated with a 3-way switch.
Temperature range
The carburettor heater is used in the following temperature
range: ±0º C 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"
NOTE! The carburettor heater reaches maximum temperature
after about 3 minutes. It is therefore important that the saw is
not run for longer with the heater switched on. If the switch is
left on for longer the carburettor will overheat and lead to
running problems or starting problems.

Winter use

During winter time, powder snow and cold weather can cause
running problems, such as:
• Too low engine temperature.
• Icing on the air filter and carburetor.
Therefore some special measures are required:
• Partly reduce the air inlet of the starter and by doing that
increase the engine temperature.
