Checking Accuracy – Vertical Beam
(Fig. F)
Checking the vertical (plumb) calibration of the
laser can be most accurately done when there is a
substantial amount of vertical height available, ideally
20' (6 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.
1.
Start by marking a 5' (1.5 m) line on the floor.
2.
Turn on the laser's vertical beam and position the
unit at one end of the line, facing the line.
3.
Adjust the unit so its beam is aligned and
centered on the line on the floor.
4.
Mark the position of the laser beam on the ceiling
(a). Mark the center of the laser beam directly
over the midpoint of the line on the floor.
5.
Reposition the laser at the other end of the line on
the floor. Adjust the unit once again so its beam is
aligned and centered on the line on the floor.
6.
Mark the position of the laser beam on the ceiling
(b), directly beside the first mark (a).
7.
Measure the distance between these two marks.
• If the measurement is greater than the values shown
below, the laser must be serviced at an authorized
service center.

Using the Laser
Leveling the Laser
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.
If the laser has been tilted so much that it cannot
self-level (> 4°), the laser beam will flash. There are
two flashing sequences associated with the out of
level condition.
• Between 4° and 10° the beams flash with a constant
blink cycle
• At angles greater than 10° the beams flash with a
three blink cycle.
When the beams flash THE LASER IS NOT LEVEL
(OR PLUMB) AND SHOULD NOT BE USED FOR
DETERMINING OR MARKING LEVEL OR PLUMB.
Try repositioning the laser on a more level surface.
Using the Pivot Bracket
The laser has a magnetic pivot bracket (Figure
permanently attached to the unit.
WARNING:
Position the laser and/or wall mount
on a stable surface. Serious personal injury
or damage to the laser may result if the
laser falls.
