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. F)
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. Make sure the
laser is facing straight ahead.
2. Turn on the laser's horizontal beam and pivot the laser ap-
proximately 45º so that the right-most end of the laser line is
striking the opposing wall at a distance of at least 30' (9 m).
Mark the center of the beamo (a).
3. Pivot the laser approximately 90º to bring the left-most end
of the laser line around to the mark made in Step 2. Mark
the center of the beam (b).
4. Measure the vertical distance between the marks.
5. If the measurement is greater than the values shown below,
the laser must be serviced at an authorized service center.

Checking Accuracy – Horizontal Beam, Pitch
Direction (Fig. G)
Checking the horizontal pitch calibration of the laser requires
a single wall at least 30' (9 m) 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
18

30' (9 m) 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.
6. Adjust the height of the laser so that the center of the beam
is aligned with the nearest mark (d).
7. Mark the center of the beam (e) directly above or below the
farthest mark (c).
8. Measure the distance between these two marks (c, e).
9. If the measurement is greater than the values shown below, the
laser must be serviced at an authorized service center.

Checking Accuracy – Vertical Beam (Fig. H)
Checking the vertical (plumb) calibration of the laser can be
most accurately done when there is a substantial amount of
vertical height available, ideally 30' (9 m), with one person on
the floor positioning the laser and another person near a ceiling
to mark the position of the beam. 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. Start by marking a 5' (1.5 m) line on the floor.
2. Turn on the laser's vertical beam and position the unit at one
end of the line, facing the line.
3. Adjust the unit so its beam is aligned and centered on the
line on the floor.
4. Mark the position of the laser beam on the ceiling (f). Mark
the center of the laser beam directly over the midpoint of the
line on the floor.
5. Reposition the laser at the other end of the line on the floor.
Adjust the unit once again so its beam is aligned and cen-
tered on the line on the floor.
6. Mark the position of the laser beam on the ceiling (g), di-
rectly beside the first mark (f).
7. Measure the distance between these two marks.
8. If the measurement is greater than the values shown below,
the laser must be serviced at an authorized service center.
