Operating Backhoe - Hitachi EX27U Operator's Manual

OPERATING BACKHOE

1. Place the bucket teeth on the ground with the bottom
of the bucket at a 45° degree angle to the ground.
2. Pull the bucket toward the machine using the arm as
the main digging force.
3. When soil sticks to the bucket, remove it by moving
the arm and/or bucket rapidly back and forth.
4. 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.
IMPORTANT: 1. When lowering the boom, avoid sud-
den stops that may cause shock load
damage to the machine.
2. When operating the arm, avoid bot-
toming the cylinder to prevent cylin-
der damage.
3. When digging at an angle, avoid strik-
ing the tracks with the bucket teeth.
4. When digging a deep excavation,
avoid striking the boom or bucket
cylinder hoses against the ground.
5. When digging with the blade posi-
tioned towards the front or when dig-
ging at an angle, avoid hitting the
blade.
