Adjust Valve Offsets
Allows the operator to adjust the hydraulic valve offsets automatically
or manually. Valve Offsets set the minimum hydraulic correction
needed to return to grade. This is not a speed adjustment.
Automatic Adjusment
1. Raise the moldboard so that both sides are a few inches above the
ground.
2. Push the "Auto Offsets" button. System Five will automatically
perform the Valve Calibration, first with left hand raise and then
lower, then repeating with the right hand side.
3. Once all four adjustments are completed, press the "ENTER"
button and the values will be saved.
