Checking 90º accuracy requires an open floor area at least 33'

laser at each step and for the location of the marks made at
each step. Always mark the center of the beam's thickness.

USING THE LASER
Leveling the Laser
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 arerequired.
If the laser has been tilted so much that it cannot self-level
(>4°), the laser beam will flash.
When the beams flash as noted above THE LASER IS
NOT LEVEL (OR PLUMB) AND SHOULD NOT BE USED FOR
DETERMINING OR MARKING LEVEL ORPLUMB.
Try repositioning the laser on a more levelsurface.
Using the Pivot Bracket (Fig.P, Q, R)
The laser has a magnetic pivot bracket (Figure P,
8
)
permanently attached to theunit.
WARNING: Position the laser and/or wall mount on
astable surface. Serious personal injury or damage to
the laser may result if the laserfalls.
• The bracket has a keyhole slot (Figure Q
10
) so it can be
hung from a nail or screw on any kind ofsurface.
• The bracket has magnets (Figure R) which allow 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 R
11
), place the Metal Enhancement Plate
(FigureR
12
) on the opposite side of thestud.
MAINTENANCE
• To maintain the accuracy of your work, check the laser
often to make sure it is properly calibrated. Refer to Field
CalibrationCheck.
• Calibration checks and other maintenance repairs may
be performed by DEWALT service centers.
• 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
tostorage.
• 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 beforestorage.
TROUBLESHOOTING
The Laser Does Not Turn On
• Fully-charge the battery pack and then reinstall it in the
laserunit.
• If the laser unit is exposed to extremely hot temperatures,
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 operatingtemperature.
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.
If the laser battery pack has a low state of charge, the
beams will flash in a distinctive pattern of 3quick flashes in
1second, followed by constant light output for 4seconds.
This flashing pattern indicates that the battery pack should
be replaced with a fully charged batterypack.
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 isstable.
ACCESSORIES (FIG. S, T, U)
The laser is packaged with a drop ceiling bracket
9
. The drop
ceiling bracket contains a steel plate and attaches to the
magnetized pivot bracket
8
(Figure S).
The drop ceiling bracket is equipped with both 1/4 - 20and
5/8 - 11female threads on the bottom of the unit).
This thread is to accommodate current or future
DEWALT
accessories. Refer to Figure T and U for examples of
accessories sold seperately. Only use
DEWALT accessories
specified for use with this product. Follow the directions
included with the accessory.
