• Mark the center of the laser beam.
Horizontal Beam ‑ Scan Direction
Checking the horizontal scan calibration of the laser requires
two walls 30' (9m) apart. 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.
1. Place the laser against the end of the wall on a smooth, flat,
stable surface that is level in both directions (Figure D 1).
2. Move the Power/Transport Lock switch to the right to turn
the laser ON.
3. Press to turn on the horizontal beam.
4. At least 30' (9m) apart along the laser beam, mark a and b .
5. Turn the laser 180 .
o
6. Adjust the height of the laser so the center of the beam is
aligned with a (Figure D 2).
7. Directly above or below b , mark c along the laser beam
(Figure D 3).
8. Measure the vertical distance between b and c .
9. If your measurement is greater than the Allowable
Distance Between b and c for the corresponding
Distance Between Walls in the following table, the laser
must be serviced at an authorized service center.

Horizontal Beam ‑ Pitch Direction
Checking the horizontal pitch calibration of the laser requires
a single wall at least 30' (9m) long. 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.
1. Place the laser against the end of the wall on a smooth, flat,
stable surface that is level in both directions (Figure E 1).
2. Move the Power/Transport Lock switch to the right to turn
the laser ON.
3. Press to turn on the horizontal beam.
4. At least 30' (9m) apart along the laser beam, mark a and b .
5. Move the laser to the opposite end of the wall (Figure E 2).
6. Position the laser toward the first end of the same wall and
parallel to the adjacent wall.
7. Adjust the height of the laser so the center of the beam is
aligned with b .
8. Directly above or below a , mark c along the laser beam
(Figure E 3).
9. Measure the distance between a and c .
10. If your measurement is greater than the Allowable
Distance Between a and c for the corresponding Distance
Between Walls in the following table, the laser must be
serviced at an authorized service center.

Vertical Beam
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' (9m), 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 1. be used.
1. Place the laser on a smooth, flat, stable surface 2. that is level
in both directions (Figure F 1).
2. Move the Power/Transport Lock switch to the right to turn
the laser ON.
3. Press and to turn on both vertical beams.
4. Mark two short lines where the beams cross a, b and also
on the ceiling c, d . Always mark the center of the beam's
thickness (Figure F 2).
5. Pick up and rotate the laser 180
the beams line up with the marked lines on the 6. level
surface e, f (Figure F 3).
6. Mark two short lines where the beams cross on 7. the ceiling g, h.
7. Measure the distance between each set of marked lines on
the ceiling c, g and d, h. If the measurement is greater than
the values shown below, the laser must be serviced at an
authorized service center.

90 Accuracy Between Vertical Beams
o
Checking 90o accuracy requires an open floor area at least 33' x
18' (10m x 5m). Refer to Figure G for the position of the laser at
each step and for the location of the marks made at each step.
Always mark the center of the beam's thickness.
1. Place the laser on a smooth, flat, stable surface that is level
in both directions.
2. Move the Power/Transport Lock switch to the right to turn
the laser ON.
3. Press to turn on the side vertical beam.
4. Mark the center of the beam at three locations (a, b, c) on
the floor along the side laser line. Mark b should be at the
midpoint of the laser line (Figure G 1).
