Plumb Error Check (Fig. Q)
1. Using a standard plumb bob as a reference, mark the top
and bottom of a wall. (Be sure to mark the wall and not the
floor and ceiling.)
2. Position the rotary laser securely on the floor (horizontally
for plumb mode) approximately 3' (1 m) from the wall.
3. Turn the laser on, and point the dot at the mark on the
bottom of the wall. Then, using the up/down arrows on the
remote control, rotate the dot upwards. If the center of the
dot scans over the mark on the top of the wall, the laser is
properly calibrated.
NOTE: This check should be done with a wall no shorter than
the tallest wall for which this laser will be used.
Using the Laser on a Tripod (Fig. C)
1. Position the tripod securely and set it to the desired height.
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. Secure the laser to the tripod by attaching the tripod
20
adapter as shown in Figure C to the laser body. The
adapter may be assembled to the bottom for level mode
or to the side for plumb mode. Place the assembly on the
tripod and screw the threaded knob on the tripod into the
female thread on the tripod adapter.
NOTE: Be sure that the tripod you are working with has a
5/8"–11 threaded screw to ensure secure mounting.
4. Turn the laser on and adjust the rotation speed and controls
as desired.
Using the Laser on a Floor (Fig. D)
The laser level can be positioned directly on the floor for
leveling and plumbing applications such as framing walls.
1. Place the laser on a relatively smooth and level surface
where it will not be disturbed or tripped over.
2. Position the laser for a level or plumb setting as shown.
3. Turn the laser on and adjust the rotation speed and controls
as desired.
NOTE: The laser will be easier to set up for wall applications if
the rotation speed is set to 0 RPM and if the remote control is
used to line up the laser with control marks. The remote allows
one person to set up the laser.
Using the DW079LR/LG Remote
The remote control allows one person to operate and set up
the laser from a distance. The LED light on the remote control
indicates a signal is being transmitted from the DW079LR/LG
laser unit. You can use all the buttons on the keypad to control
that laser unit.
If your DW079LR/LG laser unit was stamped on or after
2016‑49‑NZ (refer to Fig. E), you can use the Remote to
completely power OFF the laser unit.
To completely power OFF a DW079LR/LG laser unit (stamped
on or after 2016‑49‑NZ) using the Remote keypad, press the X‑Y
5
axis button and the MODE button

Digital Laser Detector (Fig. H–K)
Some laser kits include a D
D WALT Digital Laser Detector allows you to locate a laser
e
beam emitted by a rotary laser in bright light conditions or over
long distances. The detector can be used in both indoor and
outdoor situations where it is difficult to see the laser beam.
The detector is not for use with non‑rotating lasers but is
compatible with most rotary red‑beam and green beam lasers.
It can be set to indicate the location of the beam to either the
nearest 1/8" (3 mm) or the nearest 1/25" (1 mm). The detector
gives both visual signals through the display window
audio signals through the speaker
of the laser beam.
