Refer to Operation and Maintenance Manual, "Display Description" for more information on the icons that are on the Display.The following sections explain the procedure that is used in order to benchmark the AccuGrade - Laser System while using the Reference Elevation Operating Mode. Refer to Operation and Maintenance Manual, "Setting the Reference Elevation" in order to use the AccuGrade - Laser System and set up the AccuGrade - Laser System in the Cut/Fill Operating Mode .Benchmark the System
To make sure that the machine is grading to the correct elevation, the machine's cutting edge must be benched over a point with known elevation. This point is known as a benchmark.Using a Level Laser
Level the machine's cutting edge.
Place the center of the blade tip on the benchmark.Make sure that you do not move the benchmark. If necessary, put the blade tip next to the benchmark.
Press the left reset key (7) when the center of the blade is on the benchmark. The mast will begin to move automatically in order to search for the laser beam. The search for the laser beam will stop when the laser receiver is on-grade.This process is called auto benching.Note: In order to obtain the best results, the cutting edge must be parallel to the laser beam.The following Illustration shows the way the machine's cutting edge must be positioned for proper benching with a level laser.
