Cross Slope
Troubleshooting for Inconsistent Cross Slope
Probable Causes
The slope sensor needs to be calibrated
Improper mounting of the angle sensor
Tire pressure is too low
The cutting edges are uneven
Excessive play of the cutting edgeIsolating the Problem
Perform the full sensor calibration. Refer to the following procedure: Testing and Adjusting, KENR8982, "Full Sensor - Calibrate"
Ensure that the tire pressure is within the specified limits according to the manufacturer.Note: The sidewall of a bias ply tire will flex less than the sidewall of a radial tire. The bias ply tire is a much more stable platform. The flex of the sidewall affects the system by changing the attitude of the angle sensor. When the rear tires have a load applied, the nose of the machine will be raise, causing the angle sensor to read incorrectly. Bias ply tires are less likely to lope because when it comes under a heavy load it will be more likely to slip than squat, which initiates the loping condition.
Check the cutting edge for excessive wear or uneven edges. Use a string line to check the cutting edge. By running a string line from one cutting edge tip to the other cutting edge tip, you can tell if the cutting edges are uneven. The string should be relatively level with the cutting edge.
Illustration 1 g01379294
Check the cutting edge for straightness. The row of bolts that hold the cutting edge to the blade should be straight. Refer to the procedure below:
Run a string line across the holes that attach the cutting edge. The string line should go from Point (A) to Point (B) or the two outermost holes.
The tolerance for the holes is 1.8 mm (0.07 inch) above or below the center line. This means that if you measure from the string line to the top of any hole, it should be within 1.8 mm (0.07 inch), or if you measure the distance from the string line to the bottom of the hole it should be within 1.8 mm (0.07 inch)The AccuGrade System Vertical/Horizontal Positions or Cut/Fill Values are not Correct
Probable Causes
The values for the blade measurements or the blade wear are incorrect.
The base station is configured incorrectly.
A vertical offset on the machine is active.
A horizontal alignment or the offset is active.
A reference surface is selected rather than the design.
The AccuGrade system is correct. However, the survey stake is incorrect, or the survey stake was disturbed.
The radio is synchronized to another nearby base station.
A mast is bent.Isolating the Problem
Verify that the correct machine configuration file is selected.
Verify the blade measurements and the blade wear values. If the blade wear value was entered as a horizontal value and a vertical value, ensure that these values were not interchanged by mistake. Compare the distance between the receivers with the distance that was computed. Use the "Get Position" soft key in the "Diagnostics - GPS" screen in order to get the distance between the receivers.
Verify that any vertical offset value is correct. Ensure that a reference surface is not selected instead of the design
