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. Select optional blade tilt display

and blade tilt accuracy if desired.

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. Check blade tilt also if blade tilt indication is selected.

Installation - Slope Matching

The blade tilt indicator can be nulled or set to zero at a blade slope other than

level. This is used for matching an existing slope or setting the blade to a

predetermined slope.

The factory default setting of the blade tilt indicator is level. To set the blade

tilt indicator at a slope other than level, position the blade at the desired slope.

Ensure the receiver is aligned properly side to side and front to back with the

blade.

With the receiver on, press and hold the power switch and immediately press

and hold both the blade tilt switch and the display brightness switch. Continue

holding all three switches until a "0" symbol followed by a "Y" symbol is brieﬂy

displayed. The blade slope is now nulled at the existing slope.

"Y" symbol "O" symbol

To reset the blade tilt indication back to level, position the blade to level and

check with a four-foot level or other method. Repeat the above calibration

procedure with the blade level.

This procedure may also be used to correct the display when a mast is not

aligned properly to the blade.
