Laser Control
For Laser Control a laser transmitter is used to produce a plane of
light which becomes the grade control reference for the job site. The
laser receiver will control the blade to cut grade parallel to the laser
beam reference.
When the laser beam is in the center of the receiver, it indicates an On
Grade signal.
