5. Pick up and move the laser to b.
6. Press to turn on the front vertical beam too (Figure G 2).
7. Position the front vertical beam so it crosses precisely at b,
with the side beam aligned with c (Figure G 2).
8. Mark a location e along the front vertical beam at least 14'
(4m) away from the unit (Figure G 2).
9. Rotate the laser 90o so the side vertical beam now passes
through b and e (Figure G 3).
10. Directly above or below a, mark f along the front
vertical beam.
11. Measure the distance between a and f. If the measurement
is greater than the values shown below, the laser must be
serviced at an authorized service center.

Using the Lasers
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. 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 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 H 1) 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 fine adjustment knob (Figure H 2) to help
you line up the laser beams. Place the unit on a flat 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 J 1)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 J) the Metal
Enhancement Plate (Figure J) 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 D
WALT service centers.
e
•
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.
Troubleshooting
The Laser Does Not Turn On
•
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 50 ˚C (120 ˚F), 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.
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 Pendulum Lock switch (B). The Pendulum 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. This thread is to
