Channels 006 and 007: Calibrating Bale Shape Potentiometer-Fine Tuning

Check and adjust the bale density to the highest pressure that will ever be used. (See "Adjusting Bale Density" in "Operating the Baler-General Purposes" section.)

"CH006" allows to set the position of right bale shape potentiometer and "CH007" the left bale shape potentiometer.

The adjusting procedure is the same for both sides. Use the appropriate channel for each side.

IMPORTANT: Calibration should be done with soft core off (if equipped).

When in the diagnostic mode neither the automatic wrap cycle nor the oversize bale warning will function. There is a risk of making an oversize bale and causing damage to baler. Observe the mechanical size indicator on front of baler and avoid baling near the red zone. It may be necessary to make two bales to adjust both potentiometers.

NOTE: Proper windrow formation is important for this adjustment. Windrow width MUST be half or less than half of the bale chamber width OR full width. If it is full width, it must have a uniform density.

1. Begin baling and make a 100-115 cm (3 ft 4 in.-3 ft 9 in.) bale in the chamber.

2. Stop tractor leaving engine running.

3. Select "CH006" to calibrate right side potentiometer or "CH007" for left side potentiometer.

4. Begin driving down the windrow to feed crop into the extreme right side of baler for "CH006" or to the extreme left side for "CH007". Be sure to crowd the end of the pickup to completely fill the right end of bale. If necessary, allow some hay to be missed off the end of the pickup to ensure maximum end density.

5. Drive until calibration numbers on digital display stop increasing. Continue for a short distance, stop, and disengage PTO. The belt on right side is now at its tightest.

6. The value (±2) displayed on LCD screen should be "556".

If "556" is not displayed:

  • Shut off tractor engine.
  • Remove shield of potentiometer (A).
  • Loosen the two mounting screws (B).
  • Rotate potentiometer (A) very slowly until the value "556" appears on LCD screen.

    IMPORTANT: Do not overtighten potentiometer or damage may occur.

  • Tighten potentiometer while "556" is displayed.

7. Exit diagnostic mode and finish the bale.

8. Reinstall shield of potentiometer.

9. Repeat procedure for opposite side.
