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

adapter

20

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

axis button

5

and the MODE button

2

simultaneously.

Digital Laser Detector (Fig.H–K)

Some laser kits include a DeWALT Digital Laser Detector. The

DeWALT Digital Laser Detector allows you to locate a laser

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

22

and

audio signals through the speaker

23

to indicate the location

of the laserbeam.
