OPERATING PROCEDURE (CONT’D)
Excavating (Cont’d)
Figure OI-101
Extend the arm and uncurl the bucket to dump the
material into a pile or truck [Figure OI-101].
IMPORTANT
Avoid operating hydraulics over relief pressure.
Failure to do so will overheat hydraulic components.
I-2220-0503
Figure OI-102
Do not dig under the excavator [Figure OI-102].
Do not use the bucket as a breaker or pile driver. It is
better to excavate hard or rocky ground after breaking it
with other equipment. This will reduce damage to the
excavator.
Do not move the excavator while the bucket is in the
ground.
Dig only by moving the boom and arm towards the
Excavator.
Do not back dig (digging by moving the boom and arm
away from the excavator). Damage to the X-Change and
attachments may occur.
