COLD CLIMATES
WARNING

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 battery
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.

degree below 0°C.

key to position « » (START) for maximum 15 seconds.

q
If the engine does not start at the first attempt, repeat the
operations 1 and 2 after waiting for at least 30 seconds, in
order not to overload the battery.
