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 

A

2

) when the laser is not in use. If the switch 

is not placed in the OFF position, the laser will not turn 
off.

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 or wall. 

Securely attach the laser to the bracket.

• Using the 1/4-20 thread on the bottom of the laser 

(Figure 

G

1

), position the laser on the 1/4-20 

thread on the bracket arm (Figure 

G

2

).

• Turn the bracket knob (Figure 

G

3

) clockwise to 

lock the laser on the 1/4-20 thread on the bracket 
arm.

• The bracket has magnets and a keyhole for hanging 

the laser from a wall (Figure 

G

).
