• If using X-axis slope, the X-axis LED (Figure
A
15
) will light,
or if using Y-axis slope, the Y-axis LED (Figure
A
14
) will light
instead.
7.
When in Slope Mode, press or to tilt the laser head up and
down (adjust the elevation of the laser beam).
• Each quick press of
or will move the slope by 0.01º (1/16”
@ 30ft. or 1.6mm @ 10m).
• If you press and hold
or between 2 sec - 10 sec, the
slope will move from 0.01º/sec to 0.2º/sec.
• If you press and hold
or longer than 10 sec, the slope
will move 0.2º/sec.
8.
To turn off the laser unit, press and hold the power button for 3
secs.
9.
BEFORE using the laser for your first project, follow the
instructions for Checking the Calibration.
NOTE: When you press the Slope Mode button
again, the laser
will return to self-level mode.
Checking the Calibration
Field calibration checks should be done frequently. This section
provides instructions for performing simple field calibration checks
of your DeWALT Rotary Laser. Field calibration checks do not
calibrate the laser. That is, these calibration checks do not correct
errors in the leveling or plumb capability of the laser. Instead, these
checks indicate whether or not the laser is providing a correct level
and plumb line. These checks cannot take the place of professional
calibration performed by a
DeWALT service center.
Level Calibration Check (X-axis)
1.
Position a tripod securely on the floor between two walls that are at
least 50 feet apart. The exact location of the tripod is not critical.
2.
Make sure that the top of the tripod is roughly level.
• The laser will self-level only if the top of the tripod is within ±
5˚ of level.
• If the laser is set up too far out of level, it will beep when it
reaches the limit of its leveling range. No damage will be done
to the laser, but it will not operate in an “out of level” condition.
3.
Attach a tripod adapter (Figure
G
1
) to the laser unit. The
adapter may be assembled to the bottom for level mode (Figure
G
2
) or to the side for plumb (vertical) mode (Figure
I
3
).
4.
Place the laser with the attached adapter on the tripod and
screw the threaded knob on the tripod into the female thread on
the tripod adapter.
5.
Position the laser unit on the tripod so that the laser’s X-axis
points directly toward one of the walls (Figure
M
1
).
6.
Turn the laser unit on and allow it to self-level.
7.
Where the beam appears on the left wall, mark point A, and where
the beam appears on the right wall mark point B.
8.
Turn the laser unit 180º so that the X-axis points directly toward
the opposite wall (Figure
M
2
).
9.
Allow the laser unit to self-level.
10.
Where the beam appears on the left wall, mark point AA, and
where the beam appears on the right wall mark point BB.
11.
Calculate the Total Error using the following equation:
Total Error = (AA-A) - (BB-B)
12.
If your Total Error measurement is greater than the Allowable
Error for the corresponding Distance Between Walls in the
following table, the laser must be serviced at an authorized
service center.
L (Distance Between
Walls)
Allowable Error
40′ (15m) 3/64” (1.5mm)
50′ (20m) 1/16” (2mm)
70′ (25m) 3/32” (2.5mm)
100’ (30m)
1/8” (3mm)
