Operation
Operating Tips
• To extend battery life per charge, turn the laser off when it
is not in use.
• To ensure the accuracy of your work, check the laser
calibration often. Refer to Calibrating the Laser.
• Before attempting to use the laser, make sure the tool is
positioned on a relatively smooth, secure surface.
• Always mark the center of the laser line or dot. If you
mark different parts of the beam at different times you will
introduce error into your measurements.
• To increase working distance and accuracy, set up the
laser in the middle of your working area.
• When attaching to a tripod or wall, mount the laser
securely.
• When working indoors, a slow rotary head speed will
produce a visibly brighter line, a faster rotary head speed
will produce a visibly solid line.
• To increase beam visibility, wear Laser Enhancement
Glasses and/or use a Laser Target Card to help find the
beam.
• Extreme temperature changes can cause movement or
shifting of building structures, metal tripods, equipment,
etc., which can effect accuracy. Check your accuracy often
while working.
• When working with the
DeWALT
Digital Laser Detector, set
the laser’s rotation speed to the fastest setting.
• If the laser is dropped or has suffered a sharp blow, have
the calibration system checked by a qualified service
center before using the laser.
Control Panel (Fig. A, B)
The laser is primarily controlled by the power button 1, the
mode button 2 , the speed button 3and the scan mode button
4. These features are then modified when used with either the
Axis selection button 5(DW079LR/LG in Slope mode only), or
the two direction/elevation adjustment buttons 6and 7.
The direction/elevation adjustment buttons control the rotational
direction of the laser head as well as adjust the elevation of the
beam when the unit is in slope mode. These buttons can also
be used to incrementally rotate the beam when the unit is in
Scan mode.
The buttons on the DW074LR control panel, DW079LR/
DW079LG control panel, and the DW079LR/DW079LG Remote
keypad all work the same, unless otherwise indicated.

Power Button
The Power button is used to turn the laser unit on and off.
• To power ON the DW074LR or DW079LR/LG laser unit,
press the Power button once.
• To completely power OFF the DW074LR or DW079LR/LG
laser unit, press the power button for 3 sec.
Speed/Rotation Button
The speed button 3is used to adjust the rotation speed of the
laser beam through its 4 preset speeds (150, 300, 600, and
1200 RPM).
Scan Mode Button
15˚/45˚/90˚
The scan mode button 4is used to make the laser head
sweep back and forth, creating a short, bright laser line. This
short line is much brighter and more visible than when the unit
is in full rotation mode.
Using Scan Mode
• To enter Scan Mode, push and release the scan mode
button 4. To cycle through the scan angles, continue to
press the button until you reach the desired angle.
• The direction of the scan zone can be controlled with the
arrow buttons 6and 7.
Slope Mode Button
• To activate Slope Mode press the slope mode button 2.
• To return to self-leveling mode and re-engage full self-
leveling, press and hold the mode button 2again.
Setting the Slope Direction
When Slope Mode is activated, the unit automatically engages
the X- Axis. This allows you to slope the laser in the direction of
the X-Axis, as indicated by the “gunsights” on the rollcage.
The LED light 11 or 12 indicates the current slope direction.
DW079LR/LG only: In certain situations, it may be desirable
to slope the laser in the Y-axis. The direction of Slope Mode
can be changed back and forth between the Y-axis and the
X-axis by pressing the X-Y axis button 5. The selected axis is
identified by LED light 24 or 25 .
Setting the Amount of Slope
1. Turn on Slope Mode.
2. Select the desired axis.
3. Use the Arrow buttons (Fig. B, 6and 7) to tilt the laser
rotor head up and down.
-Each quick press of an Arrow button will move the slope
by 0.01º (1/16" @ 30ft. or 1.6mm @ 10m).
-If you press and hold an Arrow button between 2 sec-
10 sec, the slope will move from .0.01º/sec to 0.2º/sec.
-If you press and hold an Arrow button longer than 10
sec, the slope will move 0.2º/sec.
Arrow Buttons (Fig. B, R)
The arrow buttons ( B6and 7) are used for different
functions depending on the operating mode of the laser unit.
• In Self-Leveling Horizontal Mode,the arrow buttons
rotate the direction of the laser beam clockwise or counter-
clockwise during rotation, or adjust the position of the laser
beam clockwise or counter-clockwise during Scan Mode.
• In Self-Leveling Vertical Mode, the arrow buttons rotate
the direction of the laser beam clockwise or counter-
clockwise during rotation, or adjust the position of the laser
beam clockwise or counter-clockwise during Scan Mode.
• In Slope Mode, the arrow buttons are used to tilt the
laser head.
Turning the Laser On (Fig. E, B)
1. Insert the fully charged 20V battery pack as shown in
Figure E.
2. Gently press the power button 1to power ON the laser.
-The power LED indicator light 9will illuminate
-Self-leveling mode is activated automatically and
the laser unit will self-level. Once the laser unit is
level, the beam will rotate once at 600 RPM in the
clockwise direction.
-After 10 sec., Hi Mode (Anti- Drift) is activated
automatically and the Hi LED 8will illuminate.
3. Press the speed/rotation button 3to adjust the rotation
speed. The direction can be changed using buttons 6and
7.
4. Press the Scan button 4to set the laser to scan in 0°, 15°,
45°, or 90° degree mode.
If you turn ON Slope Mode, the Slope LED
(
12
) will light. If using
X-axis leveling, the X-axis LED
(
24
) will light, or if using Y-axis
leveling, the Y-axis LED (
25
) will light instead.
Calibrating the Laser (Fig. O, P)
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 checks do not correct
errors in the leveling or plumbing capability of the laser. Instead,
the 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.
DW074_DW079 User Manual - NA - TRANSLATED.indd 12 5/17/2018 2:05:33 PM

Level Calibration Check (X-axis)
1. Set up a tripod between two walls that are at least 50 feet
apart. The exact location of the tripod is not critical.
2. Mount the laser unit on the tripod so that the X-axis points
directly toward one of the walls.
3. Turn the laser unit on and allow it to self-level.
4. Mark and measure points A and B on the walls as shown
in Figure O.
5. Turn the entire laser unit 180º so the X-axis points directly
toward the opposite wall.
6. Allow the laser unit to self-level, and mark and measure
points AA and BB on the walls as shown in Figure P.
7. Calculate the total error using the equation:
Total Error = (AA – A) – (BB– B)
8. Compare total error to the allowable limits shown in the
following table.
Distance
Between Walls
Allowable Error
DW074LR
Allowable Error
DW079LR/DW079LG
40 ft. 3/32" 3/64"
50 ft. 1/8" 1/16"
70 ft. 5/32" 3/32"
100 ft. 1/4" 1/8"
Level Calibration Check (Y-axis)
Repeat the procedure above, but with the laser unit positioned
so the Y-axis is pointed directly toward the walls.
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 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 Cto 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.
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, you can use the Remote to completely power OFF the
laser unit.

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 (DW0743R) and green
beam (DW0743G) 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.
The
De
WALT Digital Laser Detector can be used with or without
the detector clamp. When used with the clamp, the detector can
be positioned on a grade rod, leveling pole, stud or post.
Installing a Battery in the Detector (Fig. H)
The Digital Laser Detector is powered by a 9 volt battery. To
install the battery provided, lift up on the battery compartment
cover 21 . Place the 9 volt battery in the compartment, aligning
the battery as shown.
Detector Controls (Fig. I)
The detector is controlled by the power button 26 and the
accuracy mode button 27 .
When the power button is pushed once, the detector is turned
on. The top of the display window shows the accuracy icon
27 , and the volume icon 28 . To decrease the volume of the
audible signal that the detector emits when it senses a laser
beam, push the button again; one of the half circles next to the
horn icon will dissappear. To turn off the audible signal push the
button a third time; the volume icon will dissapear. The
DeWALT
Digital Laser Detector also has an auto shut-off feature. If a
rotary laser beam does not strike the beam detection window,
or if no buttons are pressed, the detector will shut itself off in
about 30 minutes.
When the detector is on, the top of the window shows an
accuracy mode icon. Either the ±1/25" (1 mm) accuracy mode
icon 53 will appear, or the ±1/8" (3 mm) accuracy mode icon
54 will appear. When the ±1/25" (1 mm) accuracy mode icon
appears, it indicates that the detector will give an “on grade”
reading only when the laser beam is on grade or no more
than 1/25" (1 mm) above or below it. When the 1/8" (3 mm)
accuracy mode icon appears, it indicates that the detector will
give an “on grade” reading when the laser beam is on grade
or approximately 1/8" (3 mm) above or below it. Push the
accuracy mode button 27 once to change the accuracy mode.
Detector Operation (Fig. I, J)
1. Set up and position the rotary laser that you will be using
according to the manufacturer’s directions. Turn the laser
on and make sure that the laser is rotating and emitting a
laser beam. NOTE: This detector has been designed to be
used only with a rotating laser. The detector will not work
with a stationary beam laser level.
2. Turn the detector on by pressing the power/volume
button 26 .
3. Adjust the volume as desired as described in the
Detector Controls.
4. Position the detector so that the detector window 22 is
facing the laser beam produced by the rotary laser. Move
the detector up or down within the approximate area of the
beam, until you have centered the detector. For information
about the display window indicators and the audible signal
indicators, refer to the table titled Indicators (Fig. J).
5. Use the marking notches 30 to accurately mark the
position of the laser beam.

• If the detector still does not turn on, take the detector to a
DeWALT
service center.
The detector’s speaker makes no sound.
• Ensure that the detector is on.
• Press the power/volume button. It will toggle from high, to
low, to mute.
• Ensure that the rotary laser is spinning and that it is emitting
a laser beam.
• If the detector is still not making any sound, take it to a
DeWALT
service center.
The detector does not respond to a stationary laser beam.
The
DeWALT
Digital Laser Detector has been designed to work
only with rotary lasers.
The detector gives off a tone but the LCD display window
does not function.
• If the detector is very cold, allow it to warm up in a
heated area.
• If the LCD display window is still not functioning, take the
detector to a
DeWALT
service center.
Mounting Bracket (Fig. M, N)
Some laser kits include a Wall Mount. It can be used for
attaching the tool to track or ceiling angle and to aid in
acoustical ceiling installation. Follow the directions below for
using the wall mount.
CAUTION: Before attaching the laser level to wall
track or ceiling angle, be sure that the track or angle is
properly secured.
1. Place the laser on the mounting base 37 aligning the 5/8–
11 screw hole on the tripod adapter ( 20 , Fig. C) attached
to the bottom of the laser with the hole 39 in the mounting
base. Turn the mounting knob 40 to secure the laser.
2. With the wall mount measuring scale 41 facing you, loosen
the wall mount clamp locking knob 42 to open the clamp
jaws.
3. Position the clamp jaws around the wall track or ceiling
angle and tighten the wall mount clamp locking knob
42 to close the clamp jaws onto the track. Be sure that
the wall mount clamp locking knob is securely tightened
before proceeding.
CAUTION: Always use a ceiling wire hanger or
equivalent material, in addition to the wall mount
clamp locking knob, to help secure the laser level
while mounting it to a wall. Thread the wire through
the handle of the laser level. DO NOT thread the wire
through the protective metal cage. Additionally, screws
may be used to fasten the wall mount directly to the
wall as a back up. Screw holes 43are located at the
top of the wall mount.
4. Using the base leveling knob 44 approximate a level
position from the wall.
5. The tool can be adjusted up and down to the desired offset
height for working. To change the height, loosen the locking
knob 45 located on the left of the wall mount. Support the
mounting base when adjusting the height.
6. Turn the adjustment knob 46 , located to the right of the
wall mount, to move the laser level up and down to set your
height. Use the wall mount measuring scale 41 to pinpoint
your mark.
NOTE: It may be helpful to turn the power on and turn the
rotary head so that it puts a dot on one of the laser scales.
The
DeWALT
target card is marked at 1–1/2" (38 mm),
therefore, it may be easiest to set the offset of the laser to
1–1/2" (38 mm) below the track.
7. Once you have positioned the laser at the desired height,
tighten the locking knob 45 to maintain this position.

Mounting on a Grade Rod (Fig. K)
To secure your detector to a grade rod, first attach the detector
to the clamp using the 1/4"-20 threaded knob 47 on the back
of the clamp. Slide the tracks 32 on the clamp around the rail
33 on the grade rod.
1. Position the detector at the height needed and turn the
clamp knob clockwise to tighten the jaws of the clamp
around the grade securing the clamp on the rod.
2. To make adjustments in height, slightly loosen the clamp,
reposition and retighten.
Construction Grade Rod (Fig. L)
DANGER: NEVER attempt to use a grade rod in a
storm or near overhanging electric wires. Death or
serious personal injury will occur.
Some laser kits include a grade rod. The
DeWALT
Grade
Rod is marked with measurement scales on both sides and
is constructed in telescoping sections. A spring-loaded button
actuates a lock to hold the grade rod at various lengths.
The front of the grade rod has the measurement scale starting
at the bottom. Use this for measuring from the ground up when
grading or leveling jobs.
The back of the grade rod is designed to measure the height
of ceilings, joists, etc. Fully extend the top section of the grade
rod until the button locks into the previous section. Extend that
section either until it locks into the adjacent section or until the
grade rod touches the ceiling or joist. The height is read where
the last extended section exits the previous lower section, as
shown in Figure L.
Target Card (Fig. G)
Some laser kits include a Laser Target Card to aid in locating
and marking the laser beam. The target card enhances the
visibility of the laser beam as the beam crosses over the card.
The card is marked with standard and metric scales. The laser
beam passes through the red plastic and reflects off of the
reflective tape on the reverse side. The magnet at the top of
the card is designed to hold the target card to ceiling track or
steel studs to determine plumb and level positions. For best
performance when using the Target Card, the
DeWALT
logo
should be facing you.
Laser Enhancement Glasses (Fig. F)
Some laser kits include a pair of Laser Enhancement Glasses.
These glasses improve the visibility of the laser beam under
bright light conditions or over long distances when the laser is
used for interior applications. These glasses are not required to
operate the laser.
CAUTION: These glasses are not ANSI approved
safety glasses and should not be worn while operating
other tools. These glasses do not keep the laser beam
from entering your eyes.
DANGER: To reduce the risk of serious personal injury,
never stare directly into the laser beam, with or without
these glasses.
Maintenance
• Under some conditions, the glass lens may collect some
dirt or debris. This will affect beam quality and operating
range. The lens should be cleaned with a cotton swab
moistened with water.
• The flexible rubber shield can be cleaned with a wet lint-
free cloth such as a cotton cloth. USE WATER ONLY — DO
NOT use cleansers or solvents. Allow the unit to air dry
before storing.
• To maintain the accuracy of your work, check the calibration
of the laser often. Refer to Calibrating the Laser.
• Calibration checks and other maintenance repairs can be
performed by
DeWALT
service centers. Two free calibration
checks are included under the D
eWALT
One Year Free
Service Contract.
• When the laser is not in use, store it in the kit box provided.
• Do not store your laser in the kit box if the laser is wet. Dry
exterior parts with a soft, dry cloth and allow the laser to
air dry.
• Do not store your laser at temperatures below 0˚F (-18˚C)
or above 105˚F (41˚C).
WARNING: Never use solvents or other harsh
chemicals for cleaning the non-metallic parts of the
tool. These chemicals may weaken the materials used
in these parts. Use a cloth dampened only with water
and mild soap. Never let any liquid get inside the unit;
never immerse any part of the unit into a liquid. Never
use compressed air to clean the laser.
Troubleshooting
Height of Instrument Alert
The DW074LR and DW079LR/LG have a built-in alarm feature
