90º Accuracy Between Vertical Beams
Checking 90º accuracy requires an open floor area at
least 33' x 18' (10m x 5m). Refer to Figure
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.

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
c
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
