8.1 WHEN FUEL RUNS OUT
When starting the engine after fuel runs out, refill fuel and bleed air from the fuel system before starting
the engine.
PROCEDURE FOR AIR BLEEDING
1. Fill up the fuel tank with fuel until full.
2. Move the handle (1) of the water separator to the open
position (B).
3. Loosen the air bleed bolt (2) of the water separator 2 to
3 turns.
4. Re-tighten the air bleed bolt (2) once air bubble-free
fuel begins to escape from the air bleed bolt (2).
5. Turn the key of the starter switch to the ON position
and return to the OFF position after 10 to 15 seconds.
8.2 PHENOMENON WHICH IS NOT A FAULT
The following phenomena are not a fault.
• A sound is generated from the brake valve at the beginning and end of slewing.
• A sound is generated from the travelling motor when the machine travels on a steep downhill at low
speed.
• A sound is generated from around the valve when the boom is retracted to the end and the telescopic
cylinder is relieved on the retraction side.
• When the boom derricking cylinder is relieved on the lowered side, sounds are generated near the
