Installation - Grading

Position the machine so the blade is set to the desired finished elevation,

typically on a benchmark or hub stake.

Set the laser up in an appropriate location for receiver visibility and efficient

machine operation and turn it on.

Turn the receiver on, select center on-grade (grading mode) and select

the smallest deadband.

Mount the receiver to the mast.

Slide the receiver up or down until on-grade is indicated. It may be

necessary to adjust the height of the laser.

Alternatively, if the height of instrument (laser beam) to finished elevation

length is known, the receiver can be set by measuring this distance from

the cutting edge of the blade to the center on-grade mark on the back of

the receiver label.

Face the LED grade display toward the operator and tighten the clamps.

Select the desired deadband and brightness.

The LED grade display will direct the operator which way to move the blade

using the machine's controls to maintain an "on-grade" reading.

Make a sample pass with the blade "on-grade" and check to ensure the

elevation is correct.

Installation - Excavating

When using on an excavator or backhoe, the dipperstick should be vertical

and the bucket positioned so it can easily be repeated each time a grade

reading is taken. The bucket can be fully extended, curled, or levelled, as

long as it is consistent when grade readings are taken. The receiver can

be set-up in the trench or out of the trench if the cut elevation can be

determined.

In Trench Set-Up

Position the machine and dig to the desired finished elevation.

Position the bucket in the grade checking position at the finished elevation.

Set the laser up in an appropriate location for receiver visibility and efficient

machine operation and turn it on.

Mount the mast on the side of the dipper arm.

Turn the receiver on and select the offset on-grade and the smallest

deadband.

Place the receiver on the mast, tighten, and adjust the dipper arm so the

receiver is within the plumb range - solid LED's.

Slide the receiver up or down to get an on-grade display then tighten.

(The center on-grade location may be selected and set at this time).

Select the desired deadband and begin to excavate.

Take grade readings with the bucket in the grade checking position and

the LED's solid.

Take a sample reading with the bucket "on-grade" and check to ensure

the elevation is correct.
