LEVELING THE LASER
This tool is self-leveling. It is calibrated at the factory to find plumb as long
as it is positioned on flat surface within 4° of level. As long as the tool is
properly calibrated, no manual adjustments must be made.
MAINTENANCE
To maintain the accuracy of your work, have the laser checked often to
make sure it is properly calibrated. See
Field Calibration Check.
Calibration checks and other maintenance repairs may be performed by

WALT service centers.
When not in use, store the laser in the kit box provided. Do not store your
laser at temperatures below -20 ˚C (-5 ˚F) or above 60 ˚C (140 ˚F).
Do not store your laser in the kit box if the laser is wet. The laser should be
dried first with a soft dry cloth.
Field Calibration Check
CHECKING ACCURACY – PLUMB (FIG. 5–6)
Checking the plumb calibration of the laser can be most accurately done
when there is a substantial amount of vertical height available, ideally 7.5 m
(25'), with one person on the floor positioning the laser and another person
near a ceiling to mark the dot created by the beam on the ceiling (fig. 5).
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 point on the floor.
2. Place the laser so that the down beam is centered on the point
marked on the floor.
3. Allow time for the laser to settle to plumb and mark the center of
the beam created by the up beam.
4. Turn the laser 180° as shown (fig. 6), making sure that the down
beam is still centered on the point previously marked on the floor.
5. Allow time for the laser to settle to plumb and mark the center of
the dot created by the up beam.
If the measurement between the two marks is greater than shown below,
the laser is no longer in calibration.
