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 (Figure
E 1
).
2.
Move the Power/Transport Lock switch to the right (Figure
A 3
) to turn the laser ON in self-leveling mode and display
a horizontal laser beam.
3. At least 30 ′ (9m) apart along the laser beam, mark
a
and
b
.
4. Move the laser to the opposite end of the wall (Figure
E
2
).
5.
Position the laser toward the first end of the same wall and
parallel to the adjacent wall.
6. Adjust the height of the laser so the center of the beam is
aligned with
b
.
7.
Directly above or below
a
, mark
c
along the laser beam
(Figure
E 3
).
8. Measure the distance between
a
and
c
.
9. If your measurement is greater than the Allowable
Distance Between
a
and
c
for the corresponding
Distance Between
a
and
b
in the following table, the
laser must be serviced at an authorized service center.

Vertical Beam - Plumb
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 be used.
1. Place the laser at least 3.28 ft (1.0m) from a door jamb
(Figure
F 1
).
2. Move the Power/Transport Lock switch to the right (Figure
A 3
) to turn the laser ON in self-leveling mode and display
a horizontal laser beam.
3. Press once to display the vertical beam .
4.
Aim the vertical laser beam toward the door jamb .
5. Along the bottom of the laser beam, mark three locations
a
,
b
, and
c
; where
b
is midway between
a
and
c
.
6. Where the top of the laser beam appears at the top of the
door jamb, mark
e
.
7. Move the laser to the opposite side of the door jamb
(Figure
F 2
).
8. Align the bottom of the laser beam with
a
,
b
, and
c
.
9.
Where the top of the laser beam appears at the top of the
door jamb, mark
f
.
10. Measure the distance between
e
and
f
.

If your measurement is greater than the Allowable
Distance Between
e
and
f
for the corresponding

in the following table, the laser must be
serviced at an authorized service center.

Using the Laser
Operating Tips
• Always mark the center of the beam (dot) created by the
laser.
• Extreme temperature changes may cause movement of
internal parts that can affect accuracy. Check your accuracy
often while working.
• If the laser is ever dropped, check to make sure it is still
calibrated.
• As long as the laser is properly calibrated, the laser is self-
leveling. Each laser is calibrated at the factory to find level as
long as it is positioned on a flat surface within average ± 4°
of level. No manual adjustments are required.
• Use the laser on a smooth, flat, level, surface.
