OPERATING THE MACHINE
5-12
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 par-
allel to the trench. After digging to the desired depth,
move the machine as required to continue the trench.
IMPORTANT: When lowering the boom, avoid sudden
stops that may cause shock load damage to
the machine.
When operating the arm, avoid bottoming
the cylinder to prevent cylinder damage.
When digging at an angle, avoid striking the
tracks with the bucket teeth.
When digging a deep excavation, avoid
striking the boom or bucket cylinder hoses
against the ground.
GRADING OPERATION
IMPORTANT: Do not pull or push dirt with the bucket
when traveling.
Select grading mode when finishing work is required.
Position the arm slightly forward of the vertical position with
bucket rolled back, as shown.
Operate arm roll-in function while slowly raising the boom.
Once the arm moves past, the vertical position slowly lower
the boom to allow the bucket to maintain a smooth surface.
Grading operation can be more precisely done by operating
the boom, arm and bucket simultaneously.
