Installation - Grading
Position the machine so the blade can be 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 th e
elevation is correct.

Installation - Excavating
Angle Compensation for Excavation (ACE): Use the length determined by
the set-up procedure described on pages 14 to 17.
Press and hold the plumb switch to enter the ACE mode and the set-up length
entry mode.
The on-grade location will automatically switch to the center on-grade and the
wide plumb (ACE) symbol will appear on the LCD.
Single or pairs of LED's are lit and cycled up the scale as the switch is held.
Release the switch when the LED's are closest to the set-up length. An LED
blink will confirm the settings in approximately 2 seconds.
Example: If the set-up length measurement was 84 inches, the switch would
be released when the pair of LED's are lit between the 80 and 100 inch marks
on the right side scale. (If the set-up measurement was 2.13 meters, the switch
would be released between the 2.00 and 2.50 meter marks on the left side
scale.)
The LED's will blink briefly to confirm the setting selected.
If the set-up number is passed, simply continue to press the switch until it
is cycled to the correct number again. The number may also be selected by
pressing and releasing the switch while in the set-up length entry mode. The
LED's will change one increment each time the switch is pressed. Release
the switch to accept the displayed set-up length. An LED blink will confirm the
settings in approximately 2 seconds.
If the set-up length measurement is exactly a number on the scale, simply set
to the next higher number on the scale.
