Venting the fuel system

Air can enter the system if:

• The fuel tank is drained during normal operation.

• The low-pressure fuel pipes are disconnected.

• A part of the low-pressure fuel system leaks during

engine operation.

In order to eliminate air from the fuel system, proceed

as follows:

Open the venting screw on the fuel filter approx.

3 turns. Watch out for fuel spillage. Use rags or similar

around the venting screw.

Pump out fuel using the manual primer pump until fuel

free from air bubbles starts to flow out. Close the

venting screw. Note! If the pumping effect seems

poor, turn the engine somewhat so that the drive cam

for the pump changes position.

Loosen the fuel pressure pipe nuts at the injectors

and set the speed control to full speed. Turn the

engine at full starter motor speed until fuel flows from

the fuel pressure pipes. Watch out for fuel spillage.

Use rags or similar around the venting screw. Tighten

the fuel pressure pipe nuts and start the engine.

Emergency stop

A diesel engine is not dependent on a power supply for its

operation. Should a serious electrical fault occur, the engine

can continue to run but the normal stop function of the

ignition switch is inoperative. Emergency stopping of the

engine can always be done by pulling the injection pump

lever (1) backwards.
