Locate an elevated surface and lay the straight edge on surface facing away from
optical head. Check straight edge for level, shim if necessary.
Move

to end of straight edge, turn on the laser and adjust
height of optical head so that the mounted laser will shoot down the straight edge.
Adjust the rear floor slope wheel until the level in the optical head is centered. Readjustment of
height of optical block may be necessary.
Adjust the rear height adjustment set screw of the laser assembly (Lock Tight has been installed
on screw at factory, minor pressure should break seal) till laser is viewed at both ends of straight
edge equally.
Laser is now calibrated, installing lock tight or other adhesive to adjustment screw is
recommended.
