GAUGE-OIL LEVEL (DIPSTICK) 3826603 - Caterpillar

Benchmark The System
Note: A linked calibration must be done before the system can be benched.To make sure that the machine is grading to the correct elevation, the cutting edge of the machine must be benched over a point with known elevation. This point is known as a benchmark.Using a Level Laser
Level the cutting edge of the machine.
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 and hold the "OK" key when the center of the blade is on the benchmark.The "Bench" screen will open.
Use the Arrow Keys in order to choose the left or the right laser. Press the "OK" key.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.Illustration 12 shows the position of the machine's cutting edge. The blade must be positioned as shown in Illustration 12 in order to properly bench the system with a level laser.

Dual mast system
Press the "OK" key (10) again.The screen that is shown in Illustration 15 appears on the Display.The current reference elevation value and the configured units appear on the Display.
In order to edit the "Reference Elevation" value, perform the procedure that is listed below.
Place one of the blade tips over a point with known elevation.Make sure that the cutting edge is parallel to the laser plane.
Enter the reference elevation.
Press the "OK" key in order to bench the system.Only one mast needs to be benched.The AccuGrade System will begin benching.
Press the "OK" key (10) in order to save the setting and return to the "Configuration" menu.
Press the Menu Key (11) in order to return to the Guidance mode. Valve Speed
Correct valve speeds depend on the type of material that you are moving (for example, sand, hard rock, or dirt) and the tasks that you are performing (for example, base grade or finished grade). Speed of operation and Engine RPM are factors that can affect valve speeds.
Once the system is placed in automatic mode, blade movement may occur. Blade movement may exceed 21 cm (8 inches). Injury or death from crushing could occur. Ensure that all
