Caution:
If faults occur, find their cause immediately and have them eliminated in order to
prevent more serious damage! If necessary consult MAN’s customer service.
The oil pressure and coolant temperature are constantly monitored during operation.
The engine is automatically immobilised if the values fall short of or exceed the limits.
Shutting down
The load application is reduced by means of a ramp regulation from 100 to 0% over a
period of at least 3 minutes. The thermal load on the engine block is thus minimised.

Note:
The coolant pump continues to run for about 5 minutes after the engine has
stopped. The thermal load on the engine block is thus minimised.
Danger:
The gas supply must always be switched off before the ignition so that no traces
of unburned gas can pass into the exhaust gas line.
