User Manual

3. Connect a receiver to a grade rod and turn on the receiver. Make sure you
position the receiver so that it is at the correct elevation for the distance
(and grade) from the laser to the direction hub.
4. Set the grade rod on the direction hub.
Note: If only one person is manually aligning the laser, use a bipod
(commonly used with prism poles) to keep the grade rod plumb when
placing is on the direction hub.
5. Press the appropriate manual axis alignment button to align the laser plane
to the receiver. The clockwise axis alignment button rotates the laser
clockwise; the counterclockwise axis alignment button rotates the laser
counterclockwise.
6. Press and hold the axis alignment button until you get an on-grade reading
on the receiver.
Setting Up the Laser in Vertical Mode
1. Set up the laser on its side.
Note: If you’re using the laser with a tripod, an after-market vertical mounting
bracket is needed. For instruction on how to use the vertical mounting
bracket, consult the specific manufacturer’s instructions.
2. Press the manual button on the laser or radio remote control.
3. To adjust the laser beam for line direction, use the up and down buttons
on the laser or radio remote control until the laser beam matches the line
point.
4. To adjust the plumb position of the laser beam, use the up and down
buttons on the laser or the left and right buttons on the radio remote
control.
Establishing Control
Determining Height of Instrument (HI)
1. Set up the laser and turn it on.
2. Connect a receiver to a grade rod. Turn on the receiver.
3. Place the grade rod on a job-site benchmark (BM). Adjust the height of
the receiver until the receiver’s LCD shows an on-grade reading.
4. Add the grade-rod reading to the benchmark to determine the height of
instrument. Use the HI as a reference for all other elevation measurements.
