4. Turn the laser 180° as shown (Fig. F), making sure that the
down beam is still centered on the point previously marked
on the floor.
5. Allow time for the laser to settle to plumb and mark the
center of the dot created by the up beam.
If the measurement between the two marks is greater than
shown below, the laser is no longer in calibration.

Checking Accuracy - Level
Checking the level calibration of the laser unit requires two
parallel walls at least 20' (6 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. Place unit 2"–3" (5–8 cm) from first wall, facing the wall
(Fig. G).

2. Mark the beam position on the first wall.
3. Turn the unit 180˚, and mark the beam position on the
second wall (Fig. H).

4. Place the unit 2"–3" (5–8 cm) from the second wall, facing
the wall (Fig. I).

5. Adjust the height of the unit until the beam hits the mark
from step 3.
6. Turn the unit 180˚, and aim the beam near the mark on the
first wall from step 2 (Fig. J).

7. Measure the vertical distance between the beam and the
mark.
8. If the measurement is greater than the values shown below,
the laser must be serviced at an authorized service center.

Troubleshooting
The Laser Does Not Turn On
• Make sure batteries are installed according to (+), (-)
markings on battery door.
• Make sure the batteries 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 batteries to reduce the chance of
battery leakage.
• If the laser has been stored in extremely hot temperatures,
allow it to cool.
The Laser Beams Flash
The DW083 laser level has been designed to self-level up to 4°
in all directions when positioned as shown in Figure D. If the
laser is tilted so much that internal mechanism cannot plumb
itself, it will flash the laser—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 DW083 is a precision instrument. Therefore, if it is not
positioned on a stable (and motionless) surface, the tool will
continue to try to find plumb. If the beam will not stop moving,
try placing the tool on a more stable surface. Also, try to make
sure that the surface is relatively flat, so that the laser is stable.
