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. On the floor between two walls, mark a 5 ft. (1.5 m) line
that is parallel to the adjacent wall (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
the horizontal and vertical beams.
3.
Place the laser at one end of the line on the floor, making
sure the vertical laser beam is aligned and centered on the
line.
4.
Where the vertical laser beam appears on the ceiling, mark
a
. (This should be directly over the midpoint of the line on
the floor.)
5. Move the laser to the other end of the line on the floor
(Figure
F 2
).
6.
Where the vertical laser beam appears on the ceiling, mark
b
, directly beside the first mark
a
.

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.
Turning the Laser Off
Slide the Power/Transport Lock switch to the OFF position
(Figure
A 2
) when the laser is not in use. If the switch is not
placed in the OFF position, the laser will not turn off.
