Using the Pivot Bracket
E
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 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.
• The bracket has a keyhole slot (Figure
) so it can be hung from a nail or screw on any
H 1
kind of surface.
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 WALT service centers.
E
• 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 fi rst 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
)
G 1
The Laser Does Not Turn On
• Make sure AA batteries (when used) are installed
correctly according to + and – on the inside of the
battery door.
• Make sure the batteries or rechargeable pack are
in proper working condition. If in doubt, try installing
new batteries.
) which allow
H 2
• Make sure that the battery contacts are clean and
free of rust or corrosion. Be sure to keep the laser
level dry and use only new, high-quality, name brand
batteries to reduce the chance of battery leakage.
• If the laser unit is heated above 120˚F (50˚C), the
or
G 2
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 fl ash 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 fi nd 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 fl at, so that the laser is stable.
