Field Calibration Check - DeWalt DW089-XE Instruction Manual

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.

Field Calibration Check

CHECKING ACCURACY – HORIZONTAL BEAM, SCAN DIRECTION (FIG. 6)
Checking the horizontal scan calibration of the laser requires two walls 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, with the laser facing straight
ahead toward the opposing wall (0 degree position).
2. Turn on the laser's horizontal 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 to the extreme left (-90 degree position) and mark the beam
position on the opposing wall.
4. Pivot the laser to the extreme right (+90 degree position) and mark the beam
position on the opposing wall.
5. Measure the vertical distance between the lowest mark (A) and the highest mark
(B). If the measurement is greater than the values shown below, the laser must
be serviced at an authorized service center.

15.0 m (50')
CHECKING ACCURACY – HORIZONTAL BEAM, PITCH DIRECTION (FIG. 7)
Checking the horizontal pitch calibration of the laser requires a single wall at least 9 m
(30') 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 (C, D) at 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.
