Installation

Position the blade or bucket to the desired elevation (benchmark).

If using on and excavator or backhoe, the dipperstick should be vertical

and the bucket “curled” or extended to a position that can be easily

duplicated each time a reading is taken. To check that the plane of

laser light is intersecting the pipe where the receiver will be mounted,

move the receiver up and down along the length of the mounting pipe.

Ideally you should be able to move the receiver far enough in either

direction to utilize the entire reception range - receiving all the grade

displays and the lost beam indicators. If the full reception range is

not being used, raise or lower the rotating laser until the full reception

range is utilized.

Turn both the top and bottom knobs counterclockwise until the mounting

clamps in back open enough to ﬁt around the mounting pipe and place the

receiver on the pipe. Move the receiver up or down until the “On-Grade”

symbol is displayed by the LED’s. Tighten both clamps ﬁrmly by hand.

NOTE: Do not mount on painted poles if possible. Paint may accumulate

on the clamps and deteriorate the clamps gripping capacity.

When mounted to a bulldozer, motorgrader, scraper or other grading

machine, the operator can keep the blade at the proper elevation by

manually controlling the blade so that the receiver stays within the “on-

grade” zone. The LED display indicates in which direction the blade

needs to be moved to return to “on-grade”.

When mounted to an excavator or backhoe, the receiver is a grade

checker and allows the depth of cut to be monitored from the cab of

the machine by the operator. This is done by putting the dipper stick in

the vertical position and the bucket in the setup position and touching

the bottom of the ditch.

To remove the receiver from the machine, loosen the two clamps. Store

and transport the receiver in its carrying case.
