Place the unit on a at level surface and turn the
knob to the right to move the beams to the right,
or turn the knob to the left to move the beams to
the left.
• The bracket has a keyhole slot (Fig. I) so it can be
hung from a nail or screw on any kind of surface.
• The bracket has magnets (Fig. J1) 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 (Fig. J2), place
the Metal Enhancement Plate (Fig. J3) on the
opposite side of the stud.
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 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 rst with a soft dry
cloth prior to storage.

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
nd level as long as it is positioned on a at surface
within average ± 4° of level. No manual adjustments
are required.
If the laser has been tilted so much that it cannot
self-level (> 4°), the laser beam will ash. There are
two ashing sequences associated with the out of level
condition.
• Between 4° and 10° the beams ash with a constant
blink cycle
• At angles greater than 10° the beams ash with a
three blink cycle.
When the beams ash 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 (Fig. H1)
permanently attached to the unit.
WARNING:
Position the laser and/or wall mount on
a stable surface. Serious personal injury or

18
GB
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 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 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 at, so that the laser is stable.
The Battery Meter LEDs Flash
When all 4 LEDs continuously ash on the Battery
Meter this indicates that the unit has not been fully
powered off using the Power/Transport Lock switch
(Fig. C2). The Power/Transport Lock switch should
always be placed in the LOCKED/OFF position when
the laser is not in use.
Accessories
The laser is equipped with both 1/4 - 20 and 5/8 - 11
female threads on the bottom of the unit (Fig. K).
This thread is to accommodate current or future
DEWalt accessories. Only use DEWalt accessories
specied for use with this product. Follow the
directions included with the accessory.
WARNING:
Since accessories, other than those offered
by DEWalt, have not been tested with this
product, use of such accessories with this
tool could be hazardous. To reduce the risk of
injury, only DEWalt recommended accessories
should be used with this product.
If you need any assistance in locating any accessory,
please contact your nearest DEWALT service center or
go to www.2helpU.com.
Target Card
Some laser kits include a Laser Target Card (Fig. M
) to aid in locating and marking the laser beam. The
target card enhances the visibility of the laser beam as
the beam crosses over the card. The card is marked
with standard and metric scales. The laser beam
passes through the red plastic and reflects off of the
reflective tape on the reverse side. The magnet at the
top of the card is designed to hold the target card to
ceiling track or steel studs to determine plumb and
level positions. For best performance when using the
Target Card, the
DeWALT
logo should be facing you.
Laser Enhancement Glasses
Some laser kits include Laser Enhancement Glasses
(Fig. N). These glasses improve the visibility of
the laser beam under bright light conditions or over
long distances when the laser is used for interior
applications. These glasses are not required to operate
the laser.

19
GB
CAUTION:
These glasses are not ANSI approved
safety glasses and should not be used while
operating other tools. These glasses do not
keep the laser beam from entering your eyes.
CAUTION:
To reduce the risk of serious injury, never
stare directly into the laser beam with or
without these glasses.
Ceiling Mount
The laser ceiling mount (Fig. L1), if included, offers
more mounting options for the laser. The ceiling mount
has a clamp (Fig. L2) at one end which can be xed
to a wall angle for acoustic ceiling installation (Fig. L
3). At each end of the ceiling mount is a screw hole
(Fig. L4and L5), allowing the ceiling mount to be
attached to any surface with a nail or screw.
Once the ceiling mount is secured, its steel plate
provides a surface to which the magnetic pivot bracket
(Fig. L6) can be attached. The position of the laser
can then be ne-tuned by sliding the magnetic pivot
bracket up or down on the wall mount.
