1. Mark the midpoint between the two rear tires.
2. Note the slope displayed for the Mainfall.
3. Turn the grader around placing the front tires directly over the
previous rear tire midpoint marking.
4. The LCD should display the same slope as in step 1, but in the
opposite direction.
Figure 7-10.
If two different slopes are displayed...
If the second slope displayed is different from the first, recalibrate the
Mainfall Sensor and perform the test one more time. If the slopes
displayed continue to be different, your Mainfall Sensor is not
working properly.
