Minimum oil quant: 11qt + estimated consumption (0.3 quartz per hour)

Minimum oil pressure: 60 PSI

28
Q

Engine Starter Limitations

A

For ground starts, a 15 second pause is required between successive starts.
After 3 failed start attempts, or 5 minutes of continuous cranking, a cooling period of 30min is required.
For manual starts, observe a 2 minute maximum cycle time.

29
Q
