    A - Cut-off Arm

    B - Tab

    Check the position of the right-hand cut-off arm (A). The arm must contact the tab (B) firmly. If the arm is positioned correctly, proceed to the next step.

    If the position is not correct, adjust the base end of the mounting bracket as follows to obtain a firm contact:

    1. Turn off the monitor-controller and disconnect the power plug from the power source.

      Loosen the two cap screws (A) on the top end of the bracket and the two carriage bolts (B) on the bottom end of the bracket.

    3. Connect the monitor-controller power plug to the power source. Turn on the monitor-controller and access channel 018.

    4. Press the RETRACT key and move the counterknife angle to the shortest position.

    5. Tighten the cap screws and carriage bolts on the actuator bracket.

    6. Extend the actuator and recheck for a firm contact.


  13. Press the EXTEND or RETRACT key and return the actuator to approximately half way up or down.

  14. Disconnect the actuator from the power source.

    Left-Hand Side Shown

    A - Idler Pulley

    If the clearance is not within specifications, adjust the idler pulley (A) in the idler arm slot until clearance is within the specified range.


  19. Retract the actuator and re-extend it to check for correct clearance. If the clearance is still not correct, readjust the idler pulley (A) and recheck.

  20. Close the net cover and shut the actuator door.

  21. After adjustment, turn the monitor-controller ON. To return the cut-off arm to the home position, press the WRAP key. Turn the monitor-controller off to cancel the STOP alarm. If this procedure is not followed, net will be fed continuously during the next bale.

    Connect the monitor-controller power plug to the power source. Turn the tractor ignition key to the ON position. Do not start the tractor engine. Turn the monitor-controller ON.

  22. The STOP alarm sounds while cycling the actuator.

    Cycle the actuator several times using the WRAP key.

  23. Press the WRAP key and return the net knife to the home (downward) position.

  24. Turn the monitor-controller OFF.
