Heated Handles (Cs 2156W, Cs 2159W); Electrical Carburettor Heating (Cs 2156Wh, Cs 2159Wh); Winter Use - Jonsered CS2156 Operator's Manual

Heated handles (CS 2156W, CS
2159W)
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 switch is pushed upwards, the heat is switched on.
When the switch is pushed downwards, the heat is switched
off.
Electrical carburettor heating (CS
2156WH, CS 2159WH)
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.

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.
Preheat the intake air to the carburettor by using the heat from
the cylinder.
Temperature 0° ° ° ° C or colder:
The cylinder cover is designed so it can be adjusted for
running in cold weather. Twist the winter flap so that
preheated air from the cylinder can pass into the carburettor
space preventing icing of the air filter, etc.

MAINTENANCE
Temperature -5° ° ° ° C 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! When the winter plug is fitted the winter flap must
be open!
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).
