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.
- 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 connections while the diesel fuel is flowing out (tightening torque 30 N.m).
- So the I.C. engine is 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.

• Running out of fuel.
Any contact with highly pressurized fuel risks presents a risk of percutaneous penetration or burns.
Spraying fuel under high pressure can cause a fire.
Failure to follow the inspection and maintenance instructions may result in serious injury.
Never work on the high pressure system. Failure to follow this instruction may result in serious damage to the engine.
The high pressure furl system must be adjusted and repaired only by approved and suitably trained technicians.
Ensure that the level of fuel in the tank is sufficient and bleed in the following order:
- Open the I.C. engine bonnet.
- Check the condition of the fuel system
- Operate the hand pump 1 (fig. G1) 50 times to remove air from the low pressure system.
- So the I.C. engine is 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.
