• The bottom LED will illuminate and ash when the
battery level is low (10%). The laser may continue
to operate for a short time while the battery power
continues to drain, but the beam(s) will quickly dim.
• After the 12V/18V Li-ion battery is charged, and
the laser is turned ON again, the laser beam(s) will
return to full brightness and the battery indicator
level will indicate full capacity.
• If all 4 LEDs on the battery meter remain ON, this
indicates that the laser is not fully powered OFF.
When the laser is not in use, make sure the Power/
Transport Lock switch is placed to the LEFT to the
Locked/OFF position (Figure C2).
Operating Tips
• To extend battery life per charge, turn the laser off
when it is not in use.
• To ensure the accuracy of your work, check the
laser calibration often. Refer to Checking Laser
Accuracy.
• Before attempting to use the laser, make sure it is
positioned securely, on a smooth, at stable surface
that is level in both directions.
• To increase beam visibility, use a Laser Target Card
(Figure M) and/or wear Laser Enhancement Glass-
es (Figure N) to help find the beam.
CAUTION:
To reduce the risk of serious injury,
never stare directly into the laser beam with or
without these glasses. Refer to Accessories
for important information.
• Always mark the center of the beam created by
the laser.
• Extreme temperature changes can cause movement
or shifting of building structures, metal tripods,

Checking Laser Accuracy
The laser tools are sealed and calibrated at the factory.
It is recommended that you perform an accuracy check
prior to using the laser for the rst time (in case the
laser was exposed to extreme temperatures) and then
regularly to ensure the accuracy of your work. When
performing any of the accuracy checks listed in this
manual, follow these guidelines:
• Use the largest area/distance possible, closest to the
operating distance. The greater the area/distance,
the easier to measure the accuracy of the laser.
• Place the laser on a smooth, at, stable surface that
is level in both directions.
• Mark the center of the laser beam.
Horizontal Beam - Scan Direction
Checking the horizontal scan calibration of the laser
requires two walls 30′ (9m) apart. It is important to
conduct a calibration check using a distance no shorter
than the distance of the applications for which the tool
will be used.

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 (Figure H1)
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 ne adjustment knob (Figure H
2) to help you line up the laser beams. 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 (Figure I) so it can
be hung from a nail or screw on any kind of surface.
• The bracket has magnets (Figure 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 (Figure J2), place
the Metal Enhancement Plate (Figure 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.
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

18
GB
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
(Figure 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 (Figure 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 (Figure
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
(Figure 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.
CAUTION:
These glasses are not ANSI
approved safety glasses and should not

19
GB
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 (Figure L1), if included,
offers more mounting options for the laser. The ceiling
mount has a clamp (Figure L2) at one end which can
be xed to a wall angle for acoustic ceiling installation
(Figure L3). At each end of the ceiling mount is a
screw hole (Figure 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
(Figure 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.
