1. Attach the laser to one end of a wall using its pivot bracket.
2. Turn on the laser's horizontal beam and pivot the laser toward
the opposite end of the wall and approximately parallel to the
adjacent wall.
3. Mark the center of the beam at two locations (C, D) at least 30'
(9 m) apart.
4. Reposition the laser to the opposite end of the wall.
5. Turn on the laser's horizontal beam and pivot the laser back
toward the first end of the wall and approximately parallel to the
adjacent wall.
6. Adjust the height of the laser so that the center of the beam is
aligned with the nearest mark (D).
7. Mark the center of the beam (E) directly above or below the
farthest mark (C).
8. Measure the distance between these two marks (C, E). If the
measurement is greater than the values shown in Table 2, the
laser must be serviced at an authorized service center.

CHECKING ACCURACY – VERTICAL BEAMS (FIG. 7A, 7B)
Checking the vertical (plumb) calibration of the laser can be most
accurately done when there is a substantial amount of vertical height
available, ideally 30' (9 m), with one person on the floor positioning
the laser and another person near a ceiling to mark the position of the
beam. It is important to conduct a calibration check using a distance
no shorter than the distance of the applications for which the tool will
be used.
TABLE 3
1. Place the laser on the floor and turn on both vertical beams.
2. Mark the position where the beams cross on the floor (F) and
also on the ceiling (G). Always mark the center of the beams'
thickness.

3. Rotate the laser 180 degrees, and reposition it so the beam
crossing is exactly on the original mark on the floor.

4. Mark the position where the beams cross on the ceiling (H).
5. Measure the distance between the two ceiling marks. If the
4, 5
measurement is greater than the values shown in Table 3, the
laser must be serviced at an authorized service center.
