18 GL700 Series Laser Transmitter Quick Reference Guide
Aligning the axis manually
The manual axis alignment buttons (Λ Ρ)rotate the grade axis electronically (simulates
turning the laser on its tripod, with fine adjustment capability up to a maximum of ±40
degrees).
1. Set up the laser over a reference point. Make sure the laser is positioned so that the
1 and 2 axes are pointing in the right direction.
2. Using the sighting guides as a guide, rotate the laser on its tripod to align the laser
to the direction hub.
3. Turn on the laser and allow it to self-level. Set the grade value on both axes to zero.
4. Connect a receiver to a grade rod and turn on the receiver.
5. Set the grade rod on the direction hub and adjust the receiver until you get an
on-grade reading.
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.
6. Change the grade value on the cross axis, for example, to 4%. Press the appropriate
manual axis alignment button to align the laser plane to the receiver. The clockwise
axis alignment button (
Λ) rotates the laser clockwise; the counterclockwise axis
alignment button (
Ρ) rotates the laser counterclockwise.
7. Press and hold the axis alignment button until you get an on-grade reading on the
receiver again. Then dial the grade value appropriate to your application on one or
both axes.
