Operating Roll Bias (Option)

Roll bias allows the operator to tilt the entire boom ±5°, which would lower the left-hand (right-hand) side of boom and raise the right-hand (left-hand) side of boom. This option allows the boom to keep the same angle as the terrain when the machine is at a different angle. This can occur on very steep hills and on terraces.

To lower left-hand (right-hand) side:

1. Press and hold fold mode/roll bias switch (A) while pressing left-hand (right-hand) side of raise/lower switch (B). Stop pressing raise/lower switch before boom is at desired angle, as boom responds slower than roll bias cylinder and rocker.

2. To return boom to horizontal position, press and hold fold mode/roll bias switch and right-hand (left-hand) side of raise/lower switch.

NOTE: Before folding boom to transport position, verify that boom is in horizontal position.
