Fuel injection system - Bleed

WARNING
Escaping fluid!
Hydraulic fluid or diesel fuel leaking under pressure can penetrate the skin and cause infection or
other injury. To prevent personal injury: Relieve all pressure before disconnecting fluid lines or per-
forming work on the hydraulic system. Before applying pressure, make sure all connections are tight
and all components are in good condition. Never use your hand to check for suspected leaks under
pressure. Use a piece of cardboard or wood for this purpose. If injured by leaking fluid, see your
doctor immediately.
Failure to comply could result in death or serious injury.
Bleed the fuel system if:
• It has been drained.
• A new filter element has been installed.
• The tractor has run out of fuel.
• The lines leading to or from the filter have been dis-
connected.
• The injection pump has been removed and rein-
stalled.

1. Make sure there is adequate fuel in the fuel tank.
2. Loosen the air-bleed bolt (1) from the fuel injection
pump.

the air-bleed bolt is free of air bubbles.

position.
