If the machine has run out of fuel, add fuel then bleed the air from the
system before starting the engine.
PROCEDURE FOR BLEEDING AIR
1. Loosen joint bolt
2. Loosen the knob of feed pump , and move it up and down until
clear fuel containing no bubbles flows out through joint bolt .
3. Tighten joint bolt
16.2 PHENOMENA THAT ARE NO FAILURES
Note that the following phenomena are not failures:
1. When the arm is pulled in, the speed of movement will drop momen-
tarily when the arm is more or less vertical.
2. The arm speed will drop momentarily when the bucket teeth are
more or less horizontal.
3. When starting or stopping the swing, noise will be emitted from the
brake valve.
4. When going down a steep slope at low speed, a noise will be emitted
from the travel motor.
16.3 METHOD OF TOWING MACHINE
When towing the machine, use a wire rope that has ample
strength for the weight of the machine that is being towed.
If the machine sinks in the mud and cannot get out under its own
power, or if the drawbar pull of the excavator is being used to tow a heavy
object, use a wire rope as shown in the diagram on the right. Place pieces
of wood between wire ropes and body to prevent damage to ropes and
body.
At this time, never use the hook for light-weight towing.
