OPERATING THE MACHINE
5-13
Operating Backhoe
 Use the appropriate arm and bucket for the work.
(Refer to the "Bucket Types and Applications" in the
Specifications section.)

Pull the bucket toward the machine using the arm as the
main digging force.

When soil sticks to the bucket, remove it by moving the
arm and/or bucket rapidly back and forth.

Place the bucket teeth on the ground with the bottom of
the bucket at a 45 degree angle to the ground.

When trenching a straight line, position the tracks parallel
to the trench. After digging to the desired depth, move
the machine as required to continue the trench.
 When operating the arm, avoid bottoming the cylinder to
prevent cylinder damage.
IMPORTANT:

When digging at an angle, avoid striking the tracks
with the bucket teeth.

When lowering the boom, avoid sudden stops that
may cause shock load damage to the machine.

When digging a deep excavation, avoid striking the
boom or bucket cylinder hoses against the ground.

When operating the machine with the blade
positioned towards the front, the bucket teeth may
come in contact with the blade if you are not careful.

When the bucket load is dumped with the boom
raised, falling material may hit the base machine
and/or the canopy. Always be aware of loads in the
bucket during operation.
