ATTACHMENT TYPE BACKHOES

MISCELLANEOUS - BACKFILLING

To backfill an excavation, lower the extended bucket into the spoil

pile. Curl the bucket and lift it clear of the spoil pile. Swing the bucket to

the excavation and extend the bucket. Return the bucket to the spoil pile

and continue the cycle until the job is completed.

IMPORTANT: Do not backfill by using the swing circuit and dragging the

bucket sideways. Doing so could cause damage to the dipper, boom, and

swing cylinders or mainframe.

IMPORTANT: Avoid constant jarring or hammering contact between the

spoil pile and the loaded bucket as this may cause premature wear to the

backhoe pins and bushings.

MISCELLANEOUS - EXCAVATING BY A WALL

To excavate by a wall, where the wall will interfere with the stabilizer

placement, move the backhoe in at an angle to the wall. Concentrate on

getting the swing pin as close to the wall as possible while leaving enough

swing arc left to dump the spoil.

MISCELLANEOUS - HARD GROUND OPERATION

When digging in hard ground, it may be necessary to decrease the

bucket angle of entry to the point where the back of the bucket almost

contacts the ground. It may also be necessary to apply downward pressure

with the boom on the bucket.
