DRAIN
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.
IMPORTANT
Fuel under high pressure that comes into contact with the skin can penetrate the skin and cause 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 fuel 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:
- Lift up the overhead guard or the cab (see: 2 - DESCRIPTION: INSTRUMENTS AND
CONTROLS).
BLEEDING THE FUEL FILTER
- Unscrew bleeder screw 1.
- Switch on the lift truck ignition until the diesel oil flows from the bleeder screw
free of any air.
- - Tighten the bleed screw while the diesel fuel is flowing out.
BLEEDING THE INJECTION PUMP
- Open bleed screw 2.
- Switch on the lift truck ignition until the diesel oil flows from the bleeder screw
free of any air.
- Seal the bleed valve while the diesel oil is flowing.
The engine is now ready to be started.
NOTE: If the engine runs correctly for a short time then stops or runs erratically, check for possible leaks in the low pressure
circuit. If in doubt, contact your dealer.
