Calibrate Mainfall
The Main Slope (Mainfall) Sensor bolted to the frame of the machine
measures the slope of machine travel, up hill and down. Tire wear is
the primary reason for occasional Mainfall Sensor Calibration.
To perform the Mainfall Sensor Calibration:
1. Raise the moldboard so that both sides are a few inches above the
ground, position the machine on a smooth, even surface and mark
the front tire locations.
Push the "NEXT" button.
2. Wait 5 seconds until you hear a single beep.
