3.6.2.2 STARTING WITH COLD ENGINE OR IN
COLD CLIMATES
WARNING
q
Do not use any fluids or products that facilitate the cold
starting of the engine, since these are ether-based and
may cause explosions.
q
Before starting the engine, disconnect all the electric
devices (heating, air conditioning, lights, work lights,
etc.).
q
Perform the heating operation carefully. If the machine
is not properly warmed up before operating the control
levers, its response to the controls will be slow and this
may cause unexpected accidents.
q
If the battery electrolyte is frozen, do not charge the bat-
tery or start the engine with a different power source,
since the battery may catch fire.
Before charging the battery or starting the engine with a
different power source, make the electrolyte melt and
make sure that it isn't frozen any more and that there are
no leaks.
1 - Turn the key to the preheating position « » for maximum
15 seconds in the coldest weather.
The preheating time is determined according to the out-
side temperature and the ratio is approx. 1 second for
each degree below 0°C.
2 - Press the accelerator pedal completely and turn the igni-
tion key to position « » (START) for maximum 15 sec-
onds.
3 - As soon as the engine starts, release the ignition key,
which will automatically return to position « » and reduce
the speed to idling.
IMPORTANT
q
If the engine does not start at the first attempt, repeat
the operations 1 and 2 after waiting for at least 30 sec-
onds, in order not to overload the battery.

For specific applications in cold climates, request the
"COLD ARRANGEMENT" configuration to your Komat-
