   A - Belt

   B - Idler Pulley

   With channel 018 on monitor, cycle actuator using extend or retract key, so actuator moves approximately half way up or down, to loosen belt.

---




4. CAUTION: To avoid personal injury from unexpected knife movement, disconnect net wrap actuator wire connector or power plug when performing adjustment or working in area.

   Temporally move V-belt from top of idler pulley to underside of idler pulley.

5. Reconnect power source.

6. With monitor-controller in NET mode, press and hold COUNTER key while turning monitor-controller ON.

7. Continue to hold COUNTER key and press PLUS key until CH 018 appears in digital display.

8. Press EXTEND key to extend actuator fully (angle to highest position).

   A - Angle

   B - Tab

   Check position of right-hand net wrap cut-off arm (A). Arm must contact tab (B) FIRMLY. If correct, proceed to Step 10.

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

   1. Disconnect monitor-controller power plug from power source.

   3. Connect monitor-controller power plug to power source. Repeat Steps 5—7.

   4. Retract actuator fully (to shortest position), and tighten bracket mounting bolts.

   5. Extend actuator and recheck for firm contact.

10. Ensure that monitor is on channel 018. Use extend or retract key and return actuator to approximately half way up or down.

11. Disconnect actuator from power source.

12. Move V-belt to top of idler pulley.

13. Reconnect to power source.

14. NOTE: Engage brake before extending actuator.

    Right-Hand Side

    A - Clearance

    B - Tab

    C - Angle

    Right-Hand Side ONLY; Extend actuator. Check that clearance (A) from angle (C) to tab (B) on sidesheet is within specifications.

    Item	Measurement	Specification
    Angle-to-Tab On Sidesheet	Clearance	6—15 mm (1/4—9/16 in.)

    A - Idler

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

---




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

17. Close net wrap cover and shut actuator door.

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

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

19. NOTE: STOP alarm will sound while cycling actuator.

    Cycle actuator several times using WRAP key.

20. Press WRAP key and return net knife to home (downward) position. (See CHECK AND ADJUST FEED ROLL BRAKE in this section.)

21. Turn monitor-controller to OFF.
