• 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 damage to the laser may result if the
laser falls.
• The bracket has a keyhole slot (Figure
be hung from a nail or screw on any kind of surface.
• The bracket has magnets (Figure
the unit to be mounted to most upright surfaces
made of steel or iron. Common examples of suitable
surfaces include steel framing studs, steel door
frames, and structural steel beams. Before attaching
the pivot bracket against a stud (Figure

Maintenance
• To maintain the accuracy of your work, check the
laser often to make sure it is properly calibrated.
See Field Calibration Check.
• Calibration checks and other maintenance repairs
may be performed by D

• When not in use, store the laser in the kit box
provided. Do not store your laser at temperatures
below -5 ˚F (-20 ˚C ) or above 140 ˚F (60 ˚C).
• Do not store your laser in the kit box if the laser is
wet. The laser should be dried first with a soft dry
cloth prior to storage.

Cleaning
Exterior plastic parts may be cleaned with a damp cloth.
Although these parts are solvent resistant, NEVER use
solvents. Use a soft, dry cloth to remove moisture from
the tool before storage.
Troubleshooting
The Laser Does Not Turn On
• Fully-charge the battery pack and then reinstall it in
the laser unit.
• If the laser unit is heated above 120 ˚F (50 ˚C), the
unit will not turn on. If the laser has been stored
in extremely hot temperatures, allow it to cool.
The laser level will not be damaged by pressing
the on/off button before cooling to its proper
operating temperature.
The Laser Beams Flash
The lasers are designed to self-level up to an average
of 4° in all directions If the laser is tilted so much that
the internal mechanism cannot level itself, the laser
beams will flash indicating that the tilt range has been
exceeded. THE FLASHING BEAMS CREATED BY
THE LASER ARE 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.
The Laser Beams Will Not Stop Moving
The laser is a precision instrument. Therefore, if it is
not positioned on a stable (and motionless) surface,
the laser will continue to try to find level. If the beam
will not stop moving, try placing the laser on a more
stable surface. Also, try to make sure that the surface is
relatively flat, so that the laser is stable.
