• There is no need to adjust calibration if the distance
between reference point “D
1
” and “D
2
” is < 2,0 mm.
• If the distance measured is ≥ 2,0 mm then a calibration
adjustment is necessary.
• Perform the same steps for the “Y” axis as was done
for the “X” axis. Replace “X1” and “X2” with Y1” and
“Y2”
(
N4
).

.
• The LED/LCD will indicate laser tool is in Calibration
mode.
• If necessary, adjust the “X” axis by pressing
until the laser beam is aligned with “D
0
”. “D
0
” is the
halfway point between
“D
1
” and “D
2
” during “X” axis
check.
• Press
again to set the “X” axis and / or proceed to
the “Y” axis adjust.
• If necessary, adjust the “Y” axis by pressing
until the laser beam is aligned with “D
0
”. “D
0
” is the
halfway point between
“D
1
” and “D
2
” during “Y” axis
check.
• Press
again to set the “X” axis and / or proceed to
• Reference Figure
L
for resulting slope direction for
each key.
Remote Control
• The same functions / modes for each specific laser tool
are accessible through use with the keys available on
the remote.
• The laser tool can be powered OFF with the remote by
pressing both
at the same time. The laser tool
can only be powered ON with the power key on the
laser tool.
Accuracy Check and
Calibration
NOTE:
• See
Feature Set
to reference which models offer specific
functions.
• The laser tools are sealed and calibrated at the factory to
the accuracies specified.
• It is recommended to perform a calibration check prior to
its first use and then periodically during future use.
• Be sure to allow the laser tool adequate time to Auto-Level
(< 60 seconds) prior to a calibration check.
• The laser tool should be checked regularly to ensure its
accuracies, especially for precise layouts.
Horizontal Check
(See Figure
N
)
• Set the laser tool on a tripod 20 m away from a wall
with the ”X1” side facing the wall (
N1
).
• Power ON the laser tool and allow the laser tool to
Auto-Level and be sure laser is rotating.
• Go to the wall and mark a reference point “D
1
” where
the laser line is on the wall. If available, using a
detector may help in locating the beam more easily.
• Loosen the laser tool from the tripod and rotate the
laser tool 180° so that the “X2” side is now facing the
wall (
N2
).
• Go back to the wall and measure the distance between
the first reference point “D
1
” and the second reference
point “D
2
” (
N3
).
