SAVE THESE INSTRUCTIONS FOR FUTURE USE
User Safety
Personal Safety
• Stay alert, watch what you are doing, and use common
sense when operating a laser product. Do not use
the 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 protection when working in a construction
environment.
Tool Use and Care
• Do not use the tool if the 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
with another tool.
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 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
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 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
3
and 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
6
and
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.
