ACTIONS WHEN RUNNING OUT OF FUEL

When starting the engine again after running out of fuel, fill it up with fuel and bleed air from the fuel system
before stating.
Always check the fuel level to prevent running out of fuel.
For the method of bleeding air, see "METHOD FOR REPLACING FUEL PREFILTER CARTRIDGE (4-47)" and
"METHOD FOR REPLACING FUEL MAIN FILTER CARTRIDGE (4-59)".

PHENOMENA THAT ARE NOT FAILURES

Note that the following phenomena are not failures:
• When the arm is operated IN from a high position for dig-
ging under no load, the arm speed drops momentarily at
the vertical position.
• When performing bucket CURL operation from a high posi-
tion for digging under no load, the bucket speed drops mo-
mentarily at the horizontal position.
• The bucket or arm wobbles by itself during heavy-duty dig-
ging operations.
• When starting or stopping the swing, a noise is generated from the brake valve.
