Operation 15
MAN0450 (10/28/2005)
Digging near center of swing so material may be
dumped on either side will produce good results. Never
dig near stabilizers.
Continue the trench by moving machine along trench
centerline away from existing excavation. Move
machine approximately one-half the effective backhoe
reach. Moving too far will require excessive down pres-
sure for digging and hand clean-up of trench bottom.

SIDE SLOPE TRENCHING / EXCAVATING
Be careful when swinging loaded bucket on hill-
side. Always dump spoil on uphill side of backhoe
to minimize rollover possibility.
When operating on a side slope, the backhoe must be
positioned using one of these two methods as shown in
Figure 6 or Figure 7.
When operating on a side slope, always place the
trench spoil on the uphill side.
Figure 6. Level with Stabilizers

running or with bucket in raised position. Always
engage swing and boom transport locks, relieve
system pressure by operating controls, and
remove ignition key before leaving equipment.
