The ideal coolant pre-heating period is 2-3 hours before the machine is started. A pre-heating period
of more than 3 hours is not necessary, as the maximum effect has already been achieved within this
period (thermal balance).

Generator option
A generator is installed to provide a power supply to electrical consumers. The generator is driven
from the engine by V-belts. A tensioning device automatically ensures optimum belt tension.

Operating modes

The compressor works with the normal air delivery regulation and generates electrical power at the
same time.
The generator can work in two modes. These are selected by the mode switch:
■ Automatic start
