Turning the Laser On
Place the laser on a smooth, flat, level surface,

with the laser facing straight ahead toward the
opposing wall.
Turn the laser ON to display the horizontal and

vertical laser beams. Either:
• Move the Power/Transport Lock switch to the
left to keep the pendulum locked and display the
cross beams in manual mode (Figure
• Move the Power/Transport Lock switch to the
right to unlock the pendulum and display the
cross beams in self-leveling mode (Figure
).

• If the laser is tilted so much that it cannot self-
level (> 4°), or the laser is not level in manual
mode, the laser beams will flash.
• If the laser 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 level surface.
If ANY of the following statements are TRUE,

continue with the instructions for Checking Laser
Accuracy BEFORE USING THE LASER for
a project.
• This is the first time you are using the laser
(in case the laser was exposed to extreme
temperatures).
• The laser has not been checked for accuracy
in a while.
• The laser may have been dropped.
Checking Laser Accuracy
The laser tools are sealed and calibrated at the factory.
It is recommended that you perform an accuracy check
prior to using the laser for the first time (in case the
laser was exposed to extreme temperatures) and then
regularly to ensure the accuracy of your work. When
performing any of the accuracy checks listed in
this manual, follow these guidelines:
• Use the largest area/distance possible, closest

to the operating distance. The greater the area/
distance, the easier to measure the accuracy of
the laser.
• Place the laser on a smooth, flat, stable surface
that is level in both directions.
• Mark the center of the laser beam.
Horizontal Beam - Scan Direction
Checking the horizontal scan calibration of the
laser requires two walls at least 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.
Place the back of the laser against a wall and facing

straight ahead toward the opposing wall.
