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 Checking LaserAccuracy.

• Before attempting to use the laser, make sure it is

positioned securely, on a smooth, flat stable surface that

is level in bothdirections.

• To increase beam visibility, use a Laser Target Card

(FigureV).



CAUTION: To reduce the risk of serious injury,

never stare directly into the laser beam with or

without these glasses. Refer to Accessories for

importantinformation.

• Always mark the center of the beam created by thelaser.

• 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.

• If the laser has been dropped, check to make sure your

laser is still calibrated. Refer to Checking LaserAccuracy.

TURNING THE LASER ON (FIG.A)

Place the laser on a flat level surface. Slide the Power/

Transport Lock switch

3

to the right to unlock/turn ON

thelaser.

Each laser line is powered on by pressing its buttonon the

keypad

4

. Pressing the button again turns the laser line off.

The laser lines can be powered one at a time or all at the

sametime.

CHECKING LASER ACCURACY

The laser tools are sealed and calibrated at the factory.

It is recommended that you perform an accuracy check

prior to using the laser for the first time (in case the laser

was exposed to extreme temperatures) and then regularly

to ensure the accuracy of your work. When performing

any of the accuracy checks listed in this manual, follow

theseguidelines:

• Use the largest area/distance possible, closest to the

operating distance. The greater the area/distance, the

easier to measure the accuracy of thelaser.

• Place the laser on asmooth, flat, stable surface that is

level in bothdirections.

• Mark the center of the laserbeam.

FIELD CALIBRATION CHECK

Horizontal Beam - Scan Direction

(Fig.A,H, I, J)

Checking the horizontal pitch calibration of the laser requires

a single wall at least 30' (9m) long. It is important to conduct

a calibration check using a distance no shorter than the

distance of the applications for which the tool will beused.

1. Place the laser against the end of the wall on a smooth,

flat, stable surface that is level in both directions

(FigureH).

2. Move the Power/Transport Lock switch

3

to the right to

turn the laser ON (FigureA).

3. Press the button to turn on the horizontal beam

Wall Mounting

Some

DEWALT chargers are designed to be wall mountable

or to sit upright on a table or work surface. If wall mounting,

locate the charger within reach of an electrical outlet, and

away from a corner or other obstructions which may impede

air flow. Use the back of the charger as a template for the

location of the mounting screws on the wall. Mount the

charger securely using drywall screws (purchased separately)

at least 1” (25.4mm) long, with a screw head diameter of

0.28–0.35” (7–9mm), screwed into wood to an optimal

depth leaving approximately 7/32” (5.5 mm) of the screw

exposed. Align the slots on the back of the charger with the

exposed screws and fully engage them in theslots.

FUTURE USE

Charger Cleaning Instructions



WARNING: Shock hazard. Disconnect the charger

from the AC outlet before cleaning. Dirt and grease

may be removed from the exterior of the charger using

a cloth or soft non-metallic brush. Do not use water or

any cleaningsolutions.

Installing and Removing the Battery Pack

(Fig.D)

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

fullycharged.

To install the battery pack

1

into the tool handle, align the

battery pack with the rails inside the tool’s handle and slide

it into the handle until the battery pack is firmly seated in the

tool and ensure that it does notdisengage.

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

button

2

and firmly pull the battery pack out of the tool

handle. Insert it into the charger as described in the charger

section of thismanual.
