Using the Laser with the Bracket
A bracket (Figure G) is included with the laser so you can easily
attach the laser to a stud, ceiling grid, or pole.
1. Securely attach the laser to the bracket.
a. Using the 1/4-20 thread on the bottom, side, or back
of the laser (Figure C), position the laser on the 1/4-20
thread on the bracket arm (Figure G1).
b. Turn the laser knob (Figure G2) clockwise to lock the laser
on the 1/4-20 thread on the bracket arm.
2. If needed, change the height or position of the laser on
the bracket.
a. Turn the adjustment knob (Figure G3) counter-clockwise
to loosen the bracket arm.
b. Slide the bracket arm up or down to the desired height
(Figure G4). To change the bracket from 90° to 180°, slide
the bracket arm to the top of the bracket and then flip
the arm to the right (Figure G5).
c. Turn the adjustment knob (Figure G3) clockwise to lock
the bracket arm in place.
USING THE LASER
Operating Tips
• Always mark the center of the beam 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 A2) when the laser is not in use. If the switch is not
placed in the OFF position, the laser will not turn off.
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' (9 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. On the floor between two walls, mark a 5' (1.5 m) line that is
parallel to an adjacent wall. (Figure F1).
2. Move the Power/Transport Lock switch to the right
(Figure A3) to turn the laser ON in self-leveling mode and
display a 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 F2).
6. Where the vertical laser beam appears on the ceiling, mark
b, directly beside the first mark a..
7. Measure the distance between a and b.
Horizontal Beam - Pitch Direction
Checking the horizontal pitch calibration of the laser requires a
single wall at least 30' (9 m) long. 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 against the end of the wall (Figure E1).
2. Move the Power/Transport Lock switch to the right
(Figure A3) to turn the laser ON in self-leveling mode and
display a horizontal and vertical beams.
3. At least 30' (9 m) apart along the laser beam, mark a and b.
4. Move the laser to the opposite end of the wall (Figure E2).
5. Position the laser toward the first end of the same wall and
parallel to the adjacent wall.
6. Adjust the height of the laser so the center of the beam is
aligned with b .
7. Directly above or below a , mark c along the laser beam
(Figure E3).
8. Measure the distance between a and c .
9. If your measurement is greater than the Allowable Distance
Between a and c for the corresponding Distance Between a
and b in the following table, the laser must be serviced at an
authorized service center.

8. If your measurement is greater than the Allowable Distance
Between a and b for the corresponding Ceiling Height
D in the following table, the laser must be serviced at an
authorized service center.

a and b
