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.

Distance
Between Walls
9.0 m (30')
12.0 m (40')
15.0 m (50')
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
centre 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 in Table 1, the laser must be serviced at an authorised
service centre.
