Personal Safety
• Stay alert, watch what you are doing and use common
sense when operating a laser product. Do not use tool
while tired or under the influence of drugs, alcohol, or
medication. A moment of inattention while operating laser
products may result in serious personal injury.
• Use appropriate personal protective equipment including eye
proection when working in a construction environment.
Tool Use and Care
• Do not use tool if switch does not turn it on or off. Any
tool that cannot be controlled with the switch is dangerous
and must berepaired.
• Store idle laser products out of the reach of children and
do not allow persons unfamiliar with the laser product
or these instructions to operate the laser product. Laser
products are dangerous in the hands of untrained users.
• Use only accessories that are recommended by the
manufacturer for your model. Accessories that may be
suitable for one tool, may become hazardous when used on
another tool.
Service
• Have your laser product serviced by a qualified repair
person using only identical replacement parts. This will
ensure that the safety of the laser product is maintained.

The RBRC® Seal
The RBRC® (Rechargeable Battery Recycling
Corporation) Seal on the nickel cadmium,
nickel metal hydride or lithium-ion batteries
(or battery packs) indicates that the costs to
recycle these batteries (or battery packs) at
the end of their useful life have already been paid by DeWALT.
In some areas, it is illegal to place spent nickel cadmium, nickel
metal hydride or lithium-ion batteries in the trash or municipal
solid waste stream and the Call2Recycle® program provides an
environmentally consciousalternative.
Call 2 Recycle, Inc., in cooperation with DeWALT and other
battery users, has established the program in the United States
and Canada to facilitate the collection of spent nickel cadmium,
nickel metal hydride or lithium-ion batteries. Help protect our
environment and conserve natural resources by returning the
spent nickel cadmium, nickel metal hydride or lithium-ion
batteries to an authorized DeWALT service center or to your
local retailer for recycling. You may also contact your local
recycling center for information on where to drop off the spent
battery. RBRC® is a registered trademark of Call 2 Recycle,Inc.
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 Field Calibration Check under
Laser Maintenance.
• 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 Glass es
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 suffers a sharp blow, have the
calibration system checked by a qualified service center before
using the laser.
Laser Control Panel (Fig.B)
The laser is primarily controlled by the power button
1
, the
mode button
2
, the speed button
3
and the scan mode
button
4
, These features are subsequently modified using
the Axis selection button
5
(DW079LR/LG only), and two
direction/elevation adjustment buttons (
6
,
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.
Four LED indicator lights are on the control panel: power
9
,
X-axis leveling
24
(DW079LR/LG only), Y-axis leveling
25
(DW079LR/LG only) and Hi mode (anti drift)
8
.
Turning the Laser on (Fig. A, B)
1. Insert the fully charged 20V battery pack as shown in
FigureA .
2. Gently press the power button
1
to power the laser on.
- The power LED indicator light
9
will illuminate and the
unit will self level. The beam rotates once level at the
default settings of 600 RPM in the clockwisedirection.
- Self leveling mode is activated automatically after the
unit is powered on.
- Hi Mode (Anti- Drift) is activated automatically after 10
sec. The Hi LED
8
will illuminate when active.
- Press the speed/rotation button
3
to adjust the
rotation speed. The direction can be changed using
buttons
6
and
7
.
