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

Please take your spent battery packs to an

authorized DeWALT service center or to your

local retailer for recycling. In some areas,

it is illegal to place spent battery packs in

the trash. You may also contact your local recycling center

for information on where to drop off the spent battery pack.

Do not place in curbside recycling. For more information visit

www.call2recycle.org. or call the toll free number in the

RBRC®Seal.

Installing and Removing the Battery Pack

(Fig.E)

NOTE: For best results, make sure your battery pack is

fullycharged.

To install the battery pack

15

, align the battery pack with

the rails inside the laser’s battery port and slide it in until the

battery pack is firmly seated in the laser and ensure that it does

notdisengage.

To remove the battery pack from the laser, press the release

button and firmly pull the battery pack out of the battery port.

Insert it into the charger as described in the charger section of

thismanual.

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.



WARNING: These are not ANSI Z87.1 eyeprotection.

• Extreme temperature changes can cause movement or

shifting of building structures, metal tripods, equipment,

etc., which can affect 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/rotation 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.

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/rotation button

3

is 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

4

is 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.
