When the laser is not in use, keep the Power/Transport Lock
switch in the center (OFF) position (Figure
A 2
) to save
battery power .
Turning the Laser On
1. Place the laser on a smooth, flat, level surface, with the
laser facing straight ahead toward the opposing wall (0 º
position).
2.
Turn the laser ON to display the front cross 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
A 1
).
• Move the Power/Transport Lock switch to the right to
unlock the pendulum and display the cross beams in
self-leveling mode (Figure
A 3
).
3.
Press (Figure
A 4
) once to display a horizontal
laser line, a second time to display a vertical line, and
a third time to display a horizontal line and a vertical line.
4.
Check the laser beams.
• 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.
5.
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.
Level Beam Accuracy
Checking the horizontal scan calibration of the laser requires
two walls 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.
1. Place the laser on a tripod facing straight ahead toward
a wall (Figure
D 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. Mark P1 where the horizontal and vertical beams cross on
the wall.
4.
Turn the laser 180º.
5. Mark P2 where the horizontal and vertical beams cross on
the wall (Figure
D 2
).
6.
Turn the laser 180º and move it near the first wall
(Figure
D 3
).
7. Near P1, mark P3 where the horizontal and vertical beams
cross on the wall .
8.
Turn the laser 180º (Figure
D 4
).
9. Near P2, mark P4 where the horizontal and vertical beams
cross on the wall .
10.
Measure the vertical distance between P1 and P3 .
11. Measure the vertical distance between P2 and P4 .
