Activate AHHC, and press HEADER LOWER button on
control handle.
5.
Decrease sensitivity until feeder house remains steady
and does not bounce up and down.
NOTE:
This is maximum sensitivity and is only an initial setting.
The final setting must be made in field as system
reaction will vary with changing surfaces and operating
conditions.
NOTE:
If maximum sensitivity is not needed, a less sensitive
setting will reduce frequency of header height
corrections and component wear. Partially opening
accumulator valve will cushion action of header lift
cylinders and reduce header hunting.
