A 11.30 Auto. Shut-off device

–
General:
In order to avoid serious engine damage
due to insufficient lubrication (e.g. excess
tilting of engine), the mechanical shut-off
device was developed.
Function:
If the oil-pressure is too low, the fuel feed
and fuel return is shut off by a valve.
- Opening pressure on cold engine 0.4
bar
- Shut-off reaction pressure approximately
1.0 bar at 3000 rpm
- Idle speed of 800 rpm admissible up to
oil level "min".
- Once fuel system has run totally dry,
relief lever must be activated for approx.
15 seconds for bleeding after tank filling.
In case of (repair) work at the shut-off
device, the correct connection of fuel
pipes (flow direction) must be assured.
1 = inlet from fuel filter (tank)
2 = inlet to injection pump
3 = return from injection pump
4 = return to tank
