8. TROUBLES AND ACTIONS
8.1 RUNNING OUT FUEL
When starting the engine again after running out of fuel, fill with fuel, then bleed the air from the fuel
system before starting the engine.
[PROCEDURE FOR BLEEDING AIR]
1. Loosen the knob (1) of feed pump, pull it out, and then pump it in
and out until the movement becomes heavy.
It is not necessary to remove the plug at the top of the fuel
prefilter and fuel main filter.
2. Push in the knob (1) of feed pump and tighten it.
3. Start the engine.
When doing this, do not turn the starter motor continuously for more than 20 seconds. If the engine does
not start, wait for at least 2 minutes, then try again. Perform this operation a maximum of 4 times.
8.2 PHENOMENA THAT ARE NOT FAILURES
Note that the following phenomena are not failures:
• Some noise from around valves when boom is fully retracted and the boom telescoping cylinder is
released at retracted position.
• When starting or stopping the swing, noise will be emitted from the brake valve.
• When going down a steep slope at low speed, a noise will be emitted from the travel motor brake valve.
8.3 LIGHTWEIGHT TOWING HOOK
• A shackle must always be used, when connecting the wire rope.
• Hold the wire rope level and direct it straight to the track frame.
• Move the machine slowly and be careful not to apply any sudden load to the wire rope.
There is a hole in the track frame to fit the shackle when towing
light objects.
Permissible towing load: Max. 65,700 N (6,700 kg)
