Installation - Excavating
When using on an excavator or backhoe, the dipperstick should be vertical or
near vertical and the bucket positioned so it can easily be repeated each time
a grade reading is taken. The bucket can be fully extended or curled 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. Point the mast at the bucket
teeth as illustrated if checking grade with the bucket fully extended. (If checking
grade with the bucket curled or other position, point the mast to the point of the
bucket that makes contact with the ground.)
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. Adjust the plumb indication
accuracy if desired.
Loosen the receiver and slide it up or down to get an on-grade display, then tighten.
Select the desired deadband and begin to excavate.
Take grade readings with the bucket in the grade checking position and the
grade display LED's solid.
Take a sample reading with the bucket "on-grade" and check to ensure the
elevation is correct.
