5. Press the HEADER LOWER switch (A) on the control
handle until the float module and header are fully
lowered. You may need to hold the switch for several
seconds.
6. Press the HEADER RAISE switch (A) on the control
handle. The header should stop at about the halfway
point. Continue holding the HEADER RAISE switch,
and the header will rise until the feeder house reaches
its upper limit. The AHHC system is now calibrated.
NOTE:
If float was set heavier to complete the AHHC
calibration procedure, adjust to recommended
operating float after the calibration is complete.

Setting the Sensitivity of the Auto Header Height (Case IH 5088/6088/7088)

The sensitivity adjustment controls the distance the cutterbar must travel up or down before the auto header height
control (AHHC) reacts and raises or lowers the feeder house. When the sensitivity is set to maximum, only small
changes in ground height are needed to cause the feeder house to raise or lower. When the sensitivity is set to
minimum, large changes in the ground height are needed to cause the feeder house to raise or lower.
NOTE:
Changes may have been made to the combine controls or display since this document was published. Refer to the
combine operator's manual for updates.
