Caution:

Do not overload the engine. Do not exceed the maximum permissible tilt of the
engine. If faults occur, find their cause immediately and have them eliminated in
order to prevent more serious damage!

Monitor the oil pressure of the engine lubrication and coolant agent temperature during
operations.
If the monitoring devices register a drop in the lube oil pressure, switch off the engine im-
mediately.

Shutting down

Set engine to idle speed.

After engine has been under a heavy load let it run idle for approx. 5 minutes.

Turn off engine via EDC.

Danger:

Ensure that the engine cannot be started by unauthorized persons.
