CHECKING ACCURACY - LEVEL (FIG. 7–10)
Checking the level calibration of the laser unit requires two parallel walls at
least 6 m (20') 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 5–8 cm (2"–3") from first wall, facing the wall (fig. 7).
2. Mark the beam position on the first wall.
3. Turn the unit 180˚, and mark the beam position on the second wall
(fig. 8).
4. Place the unit 5-8 cm (2"–3") from the second wall, facing the wall
(fig. 9).
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. 10).
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.
Repeat steps 1 through 8 to check the front beam, left beam, and right
beam.

CHECKING LEVEL TO SQUARE BEAM 90° ACCURACY (FIG. 11a–d)
Refer to Figure 11 for the location of the DW085 at each step and for the
location of the marks made at each step. All marks can be made on the
floor by placing a target in front of the level or square beam and transferring
the location to the floor.
