Checking Cross Slope (Trim
Calibration)
Before using the Cross Slope System; check to make sure there has
not been excessive cutting edge wear from previous use. This takes
less than 5 minutes and is completed right on the jobsite.
1. Switch the Cross Slope to either the left or right side and grade a
smooth finish pass at about 50 feet long in Automatic Control.
The % slope you dial in does not matter for calibration, but it is
best to dial in a slope that will closely match the area you are
grading so you will not have to cut too much. If the ground is
fairly rough, you may need to back up and grade 2 or 3 passes
until you cut a smooth finish pass.
2. Turn the machine around, push the switch to reverse the slope,
and begin to grade slowly over the previous pass with either side
in Automatic. Slowly lower the blade and observe to see if the
cutting edge matches the previous pass. If the cutting edge
matches, no adjustment is needed.
If the cutting edge does not match:
Push the Trim button, then turn the Grade Adjustment Knob to get it
to match. Push "ENTER" and the Blade Trim Calibration is complete.
You are now ready to begin grading with the Cross Slope System.
