SYSTEMS FEATURES AND BASIC OPERATION

Figure 1-19. GB-108 on a Loader.

NOTE: In some situations, the Automatic Control
System may require a cut deeper than the
machine can handle. The machine may
lose traction, stall the engine, or the wheel
frame will be lifted off the ground to the
maximum stroke of the cylinder as the
cutting edge tries to reach finished grade.
If this occurs, set the system to manual
control, and use the joysticks to raise the
cutting edge until the machine can move
the material. Make multiple passes to cut
the area closer to finished grade and then
go back to automatic control. This allows
the high spots to be gradually removed.
Always have system in Manual setting when not
operating the loader.
3. After several passes with the Grader Blade,
stop and turn off the loader. Place the base
of the measuring pole on the graded area and
check grade elevation.
4. After a rough grade is achieved, the dead-
band (Accuracy) may be changed to a
narrower setting as required to meet the job
tolerance requirements. With a tighter dead-
band, the speed of the loader needs to be
decreased for optimum finish.
