User Manual
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 -20 ˚C (-5 ˚F ) or
above 60 ˚C (140 ˚F).
• 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.
Accuracy Check and
Calibration
Checking Accuracy –
Horizontal Beam, Scan Direction (See figure
7
Checking the horizontal scan calibration of the laser requires
two walls 9m (30') 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, with the
laser facing straight ahead toward the opposing wall (0
degree position).
2. Turn on the laser's horizontal beam and front vertical
beam and mark the beam position on the opposing wall
directly across from the laser. Always mark the center of the
beam's thickness.
3. Pivot the laser 180 degrees and mark the beam position on
the opposing wall.

4. Measure the vertical distance between the lowest mark
B
and the highest mark . If the measurement is greater
than the values shown below, the laser must be serviced at
an authorized service center.
Distance Between Walls Allowable Distance
Between Marks
9 m (30')
12 m (40') 4.0 mm (5/32")
15 m (50') 5.0 mm (7/32")
Checking Accuracy –
Horizontal Beam, Pitch Direction (See figure
Checking the horizontal pitch calibration of the laser
requires a single wall at least 30' (9m) long. 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 one end of a wall using its pivot
bracket.
2. Turn on the laser's horizontal beam and pivot the laser
toward the opposite end of the wall and approximately
parallel to the adjacent wall.
3. Mark the center of the beam at two locations (
least 30' (9m) apart.
4. Reposition the laser to the opposite end of the wall.
5. Turn on the laser's horizontal beam and pivot the laser
back toward the first end of the wall and approximately
parallel to the adjacent wall.
6. Adjust the height of the laser so that the center of the
beam is aligned with the nearest mark

Vertical Beam (See Figure
Checking the vertical (plumb) calibration of the laser can be
most accurately done when there is a substantial amount of
vertical height available, ideally 30' (9m), 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
3.0 mm (1/8")
a calibration check using a distance no shorter than the distance
of the applications for which the tool will be used.

beams.

Checking 30º Accuracy Between Vertical Beams

Checking 30º accuracy requires an open floor area at least 10m
x 5m (33' x 18'). Refer to Figure 9 for the position of the laser at
each step and for the location of the marks made at each step.
Always mark the center of the beams' thickness.

• Make sure the batteries or rechargeable pack are in proper

working condition. If in doubt, try installing new batteries.
2.0 mm (3/32")
• Make sure that the battery contacts are clean and free of
rust or corrosion. Be sure to keep the laser level dry and use
2.5 mm (1/8")
only new, high-quality, name brand batteries to reduce the
chance of battery leakage.
4 m (5/32')
• If the laser unit is heated above 50 ˚C (120 ˚F), the unit will
6 m (1/4') 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
