Cylinder Position Calibration (Continued)
10.Carefully move the arm to where it is clear of the
body (there are no interlocks during this stage). Once
arm is clear of the body, move the head to the full
UNDUMP position. This sets the full UNDUMP
position of the grabber beam. Press “OK” and then

position.
12.Place the arm in the full RAISE and full EXTEND
position. Close the grabbers to the fully CLOSED
position.

each position is correctly met. This sets the max
extended positions for the cylinders.
Press “OK” and then press "OK" again to confirm the
position.
13.Retract the arm approximately half way (this allows
for accurate visibility of the grabber beam). Place the
grabber beam in the level position. This sets the

Press “OK” and then press "OK" again to confirm the
position.
Lift Valve Minimum Currents Calibration
14.Extend each cylinder (raise, extend, dump, and
grabber) approximately half way. This will provide the
needed movement for calibration.
Note: Each valve section will take time to perform
this task and will be different from truck to truck
based on the Lift Valve and Counterbalance Valve
crack points, and how much flow each cylinder will
require to move.
Press "OK" again to confirm the position.
15.Press and hold the DUMP push button until the
grabber beam starts to move in the dump direction.
Press "OK" again to confirm the position.

17.Press and hold the UP push button until the arm
starts to move in the up direction. Press "OK" again
to confirm the position.
18.Press and hold the DOWN push button until the arm
