Operation & Maintenance Manual

OPERATING PROCEDURE (Cont’d)
Excavating (Cont’d)
Do not dig under the excavator [A].
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 toward 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.
Boom Offset
Swing the upperstructure, offset the boom to the right [B],
center [C], and left [D] to dig a square hole the width of the
machine without repositioning the excavator.
