Operating Backhoe

 Use the appropriate arm and bucket for the work.
(Refer to the "Bucket Types and Applications" in the
Specifications chapter.)
 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.
 Lower the boom smootly. Avoid stopping suddenly
as this may impact the machine.
 When digging a deep excavation, avoid striking the
boom or bucket cylinder hoses against the ground.
