OPERATING INSTRUCTIONS

OPERATING TECHNIQUES

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 place-

ment, 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.
