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. 5)
Checking the horizontal scan calibration of the laser requires two
walls 9 m (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.
TABLE 1
1. Attach the laser to a wall using its pivot bracket, with the laser
2. Turn on the laser's horizontal beam and mark the beam position
3. Pivot the laser to the extreme left (–90 degree position) and mark
4. Pivot the laser to the extreme right (+90 degree position) and
5. Measure the vertical distance between the lowest mark (A)
