Viewing the Battery Meter
When the laser is ON, the battery meter on the keypad
(Figure F7) indicates how much power remains.
Each of the four LEDs on the battery meter represents
25% of the power.
• The bottom LED will illuminate and flash when the
battery level is low (below 12.5%). 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 fresh batteries are installed in the AA Starter
Pack, or the 12V MAX 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 F2).
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, flat stable surface
that is level in both directions.
• To increase beam visibility, use a Laser Target Card
(Figure D) and/or wear Laser Enhancement Glasses
(Figure E) 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,
equipment, etc., which can effect accuracy. Check
your accuracy often while working.
• If the laser has been dropped, check to make sure
your laser is still calibrated. Refer to Checking Laser
Accuracy.

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 first 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, flat, 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.
1. Place the laser against the end of the wall on a
smooth, flat, stable surface that is level in both
directions (Figure K1).

23’ (7m) 1/4” (6mm)
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
are required.
If the laser has been tilted so much that it cannot
self-level (> 4°), the laser beam will flash. There are
two flashing sequences associated with the out of level
condition.
• Between 4° and 10° the beams flash with a constant
blink cycle
• 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.

18
EUsing the Pivot Bracket
The laser has a magnetic pivot bracket (Figure G1)
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 H2) 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.
• The bracket has a keyhole slot (Figure G2or
H1) so it can be hung from a nail or screw on any
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 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 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
• 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.
• 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
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.

19
E
The Battery Meter LEDs Flash
When all 4 LEDs continuously flash on the Battery
Meter this indicates that the unit has not been fully
powered off using the Power/Transport Lock switch
(Figure F2). 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 (I) on the bottom of the unit (Figure I).
This thread is to accommodate current or future DEWalt
accessories. Only use DEWalt accessories specified
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.DEWALT.com.
Target Card
Some laser kits include a Laser Target Card (Figure D)
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 E). 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 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 J1), if included, offers
more mounting options for the laser. The ceiling mount
has a clamp (Figure J2) at one end which can be fixed
to a wall angle for acoustic ceiling installation (Figure
J3). At each end of the ceiling mount is a screw hole
(Figure J4and J5), allowing the ceiling mount to
be attached to any surface with a nail or screw.
