OPERATING TIPS
• To extend battery life, 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.
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.
To Turn the Laser On and Off (Fig.C, D)
1. Unlock unit by sliding Lock/Power‑Unlock bar6 to theright.
2. With the laser off, place it on a flat surface. This model has three ON/OFF buttons, one for a
horizontal laser line3, one for a vertical laser line4, and one for the plumb laser spots5.
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.

ENGLISH

Field Calibration Check
Checking Accuracy – Horizontal Beam, Scan Direction (Fig. E)
Checking the horizontal scan calibration of the laser requires two walls at least 30' (9 m)
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. Attach the laser to a wall using its pivot bracket. Make sure the laser is facing
straightahead.
2. Turn on the laser's horizontal beam and pivot the laser approximately 45˚ so that the
right‑most end of the laser line is striking the opposing wall at a distance of at least 30' (9
m). Mark the center of the beam (a).
3. Pivot the laser approximately 90˚ to bring the left‑most end of the laser line around to
the mark made in Step 2. Mark the center of the beam (b).
4. Measure the vertical distance between themarks.
• If the measurement is greater than the values shown below, the laser must be serviced at
an authorized servicecenter.

Checking Accuracy – Vertical Beam (Fig. G)
Checking the vertical (plumb) calibration of the laser can be most accurately done when
there is a substantial amount of vertical height available, ideally 20' (6m), with one person
on the floor positioning the laser and another person near a ceiling to mark the position of
the beam. 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. Start by marking a 5' (1.5 m) line on thefloor.
2. Turn on the laser's vertical beam and position the unit at one end of the line, facing
theline.
3. Adjust the unit so its beam is aligned and centered on the line on thefloor.
4. Mark the position of the laser beam on the ceiling (a). Mark the center of the laser beam
directly over the midpoint of the line on thefloor.
5. Reposition the laser at the other end of the line on the floor. Adjust the unit once again
so its beam is aligned and centered on the line on thefloor.

ENGLISH

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.
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.
Using the Pivot Bracket (Fig.H, I)
The laser has a magnetic pivot bracket7 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 keyhole slot8 so it can be hung from a nail or screw on any kind
ofsurface.

ENGLISH
15
• The bracket has magnets12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.
Using the Lasers with Accessories
The lasers are equipped with a 1/4”x 20female thread on the bottom of the unit. 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.
CAUTION: The use of any other accessory not recommended for use with this tool could
behazardous.
If you need any assistance in locating any accessory, please contact DeWALT Industrial Tool
Co., 701East Joppa Road, Towson, MD 21286or call 1–800–4‑DeWALT (1–800–433–9258).
See our catalog on the World Wide Web at www.DeWALT.com.
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
• Remove the batteries and replace with fresh batteries. Ensure the battery contacts are
free ofcorrosion.

ENGLISH
16
• 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 (Fig. J)
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 BYTHE 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.
