G1 - FUEL SYSTEM
BLEED
These operations are to be carried out only in the following cases:
• A component of the fuel system replaced.
• A drained tank.
• Running out of fuel.
Ensure that the level of fuel in the tank is sufficient and bleed in the following order:
- Open the I.C. engine bonnet.
- Put the ignition on for three minutes on the lift truck, to give the lift pump time to release air from the filter.
- Switch off the ignition with the ignition key.
BLEEDING THE INJECTORS
- Remove the injectors cover 1 (fig. G1/1).
- Loosen high pressure connectors 2 (fig. G1/2) of all the injectors.
- Activate the starter until the diesel fuel flows out free of air at high pressure connectors
2 (fig. G1/2).
Do not engage the starter motor on a continual basis for more than 30 seconds and let it
cool between unsuccessful attempts.
- Tighten the connection while the diesel fuel is flowing out (tightening torque 30 N.m).
- The I.C. engine is then ready to be started up.
- Turn the I.C. engine over slowly for 5 minutes immediately after bleeding the fuel feed circuit, in order to ensure that the injection
pump has been bled thoroughly.
NOTE: If the I.C. engine functions correctly for a short time then stops or functions irregularly, check for possible leaks in the low
pressure circuit. If in doubt, contact your dealer.
