TROUBLES AND ACTIONS

RUNNING OUT OF 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.
For details of bleeding the air, see "Air Bleeding (PAGE 4-56)".

PHENOMENA THAT ARE NOT FAILURES

Note that the following phenomena are not failures:
When the arm control lever is operated to the IN position and the
work equipment is lowered under no load from a high position,
the arm speed will drop momentarily when the arm is more or
less at the vertical position.
When the bucket control lever is operated to the CURL position
and the work equipment is lowered under no load from a high
position, the bucket speed will drop momentarily when the
bucket teeth are more or less at the horizontal 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.
When the air conditioner is switched on, the work equipment operates and the machine travels somewhat slower
than when it is switched off. This should not give you any concern as it is by no means a failure but due to lowered
output of the hydraulic pump.
