Calibrate Rotation
The Cross Slope System cuts the desired slope perpendicular to the
draw bar, or "A"-frame assembly. The Rotation Sensor, which
measures the blade angle of rotation, must be calibrated so it knows
when the blade is perpendicular, or at 0 degrees, to the "A"-frame
assembly. Wear or damage to the machine's hose tray or guide rods
are the reason for occassional Rotation Sensor Calibration.
To perform the Rotation Sensor Calibration:
Figure 3-3.
1. Rotate the blade to the chisel marks on the "A"-frame assembly
provided by installer.
2. Push the "ENTER" button and the Rotation Sensor Calibration is
completed.
