The excavator boom can be slewed 45° to the right and 80°
to the left from the basic front position. This allows excava-
tion of trenches along walls, fences, etc.
OPTIMAL STABILITY WHEN DIGGING
•
Use the dozer blade to support the excavator on the
ground.
•
Never dig under the machine. Support the walls proper-
ly when excavating or working close to trenches.
•
To obtain maximum digging performance, avoid fully
extending the excavator arm. Excavate using long, flat
pulling movements of the arm (Figure 3-15).

ing near trenches. Be aware of conditions that
could cause the earth to collapse resulting in
