• A DeWALT 12V MAX* Li-ion Battery Pack (DCB120, DCB123, DCB125, or DCB127). *Maximum initial battery voltage (measured without a workload) is 12 volts. Nominal voltage is 10.8.

• A DeWALT AA Starter Pack with 4 AA batteries. Note: The AA Starter Pack is only recommended for use with the red laser. Use of any other batteries may create a risk of re.9

Charging the DeWALT Li-ion Battery

If the 12V MAX Li-ion battery pack is attached to the laser, remove it (Figure

• Rotate the laser so it is easier to access the battery pack (Figure

• While pressing down on the release button on the battery pack (Figure

#2), pull the battery pack up to unlock it from the laser (Figure

• Pull the battery pack the rest of the way up and out of the laser (Figure

Plug the charger cord into an electrical outlet.

Slide the battery pack into the charger until it snaps in place (Figure

#1). On the charger, the left indicator light will flash to let you know the battery is being charged (Figure

After the battery is fully-charged (the indicator light on the charger no longer flashes), press and hold the release button on the battery pack (Figure

#3) and slide the pack out of the charger (Figure

Slide the battery pack down in the laser until it snaps in place (Figure

#5). Installing New AA Batteries CAUTION: The AA Starter Pack is designed specically for use with DeWALT 12V compatible laser products and cannot be used with any other tools. Do not attempt to modify the product.

If the AA Starter Pack is attached to the laser, remove it (Figure

• Rotate the laser so it is easier to access the Starter Pack (Figure

• While pressing down on the release button on the Starter Pack (Figure

#2), pull the Starter Pack up to unlock it from the laser (Figure

• Pull the Starter Pack the rest of the way up and out of the laser (Figure

On the AA Starter Pack, lift up the latch to open the battery compartment cover (Figure

Insert four new, high-quality, name brand AA batteries, making sure to position the - and + ends of each battery as noted inside the battery compartment (Figure

Push the battery compartment cover down until it snaps in place.

Slide the Starter Pack down in the laser until it snaps in place (Figure

#4). Viewing the Battery Meter on the Keypad When the laser is ON, the battery meter on the keypad (Figure

#3) indicates how much power remains. Each of the four LEDs on the battery meter represents 25% of the power.

• The bottom LED will illuminate and ash when the battery level is low (below 12.5%). The laser may continue to operate for a short time while the battery power continues to drain, but the beam(s) will quickly dim.

• After fresh batteries are installed in the AA Starter Pack, or the 12V MAX Li-ion battery is charged, and the laser is turned ON again, the laser beam(s) will return to full brightness and the battery indicator level will indicate full capacity.

• If all 4 LEDs on the battery meter remain ON, this indicates that the laser is not fully powered OFF. When the laser is not in use, make sure the Power/Transport Lock switch is placed to the LEFT to the Locked/OFF position (Figure

Place the laser on a smooth, flat surface.

• Press once to display dots above, ahead, and below the laser (Figure

#3d), a second time to display two additional dots from either side of the laser (Figure

#3e), and a third time to stop displaying dots.

• You can use and together to display laser dots and lines. For example, if you press three times and twice, the laser will display cross lines and five dots (Figure

Check the laser beams. The laser is designed to self-level. If the laser is tilted so much that it cannot self-level (> 4°), the laser beam will flash.

• If the laser is tilted between 4° and 10°, the beams will flash constantly.

• If the laser is tilted greater than 10°, the beams will continually flash 3 times.

If the laser beams ash, the laser is not level (or plumb) and should NOT BE USED for determining or marking level or plumb. Try repositioning the laser on a level surface.

If ANY of the following statements are TRUE, continue with the instructions for Checking Laser Accuracy BEFORE USING THE LASER for a project.

• This is the first time you are using the laser (in case the laser was exposed to extreme temperatures).

• The laser has not been checked for accuracy in a while.

• The laser may have been dropped. 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 rst 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, at, stable surface that is level in both directions.

• Mark the center of the laser beam. Horizontal Line Accuracy - Tilt Checking the tilt of the laser’s horizontal line requires a at vertical surface at least 30’ (9m) wide.

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

• Extreme temperature changes may cause movement of internal parts that can affect accuracy. Check your accuracy often while working.

• If the laser is ever dropped, check to make sure it is still calibrated.

• As long as the laser is properly calibrated, the laser is self- leveling. Each laser is calibrated at the factory to nd level as long as it is positioned on a at surface within average ± 4° of level. No manual adjustments are required. Turning the Laser Off Slide the Power/Transport Lock switch to the OFF/Locked position (Figure

#1a) when the laser is not in use. If the switch is not placed in the Locked position, all 4 LEDs will remain lit on the Battery Meter on the keypad (

#3). Using the Pivot Bracket The laser has a magnetic pivot bracket (Figure

#1) permanently attached to the unit.

Position the laser and/or wall mount on a stable surface. Serious personal injury or damage to the laser may result if the laser falls.

• The bracket has magnets (Figure

#2) which allow the unit to be mounted to most upright surfaces made of steel or iron. Common examples of suitable surfaces include steel framing studs, steel door frames, and structural steel beams.

• The bracket has a keyhole slot (Figure

#1) so it can be hung from a nail or screw on any kind of surface. Using the Laser with Accessories

Since accessories other than those offered by DeWALT have not been tested with this laser, use of such accessories with this laser could be hazardous. Only use DeWALT accessories that are recommended for use with this model. Accessories that may be suitable for one laser may create a risk of injury when used with another laser. The bottom of the laser is equipped with 1/4-20 and 5/8-11 female threads (Figure

) to accommodate current or future DeWALT accessories. Only use DeWALT accessories specied for use with this laser. Follow the directions included with the accessory. Recommended accessories for use with this laser are available at extra cost from your local dealer or authorized service center. If you need assistance locating any accessory, please contact your nearest DeWALT service center or visit our website: http:// www.dewalt.com. Using the Laser with the Ceiling Bracket The laser ceiling bracket (if included) offers more mounting options for the laser. The ceiling mount has a clamp at one end which can be xed to a wall angle for acoustic ceiling installation. At each end of the ceiling mount is a screw hole to allow it to be hung from a nail or screw on any kind of surface. Once the ceiling mount is secured, its steel plate provides a surface to which the magnetic pivot bracket can be attached. The position of the laser can then be ne-tuned by sliding the magnetic pivot bracket up or down on the wall mount. Maintenance

• When the laser is not in use, clean the exterior parts with a damp cloth, wipe the laser with a soft dry cloth to make sure it is dry, and then store the laser in the kit box provided.

• Although the laser exterior is solvent resistant, NEVER use solvents to clean the laser.

• Do not store the laser at temperatures below -20 ˚C (-5 ˚F ) or above 60 ˚C (140 ˚F).

• To maintain the accuracy of your work, check the laser often to make sure it is properly calibrated.

• Calibration checks and other maintenance repairs may be performed by DeWALT service centers.14

Troubleshooting The Laser Does Not Turn On

• If AA batteries are being used, make sure:

• Each battery is installed correctly, according to (+) and (–) listed inside the battery compartment.

• The battery contacts are clean and free of rust or corrosion.

• The batteries are new, high-quality, name brand batteries to reduce the chance of battery leakage.

• Make sure the AA batteries or Li-ion rechargeable pack are in proper working condition. If in doubt, try installing new batteries.

• Be sure to keep the laser dry.

• If the laser unit is heated above 50 ˚C (120 ˚F), the unit will not turn ON. If the laser has been stored in extremely hot temperatures, allow it to cool. The laser level will not be damaged by using the Power/Transport Lock switch before cooling to its proper operating temperature. The Laser Beams Flash The lasers are designed to self-level up to an average of 4° in all directions. If the laser is tilted so much that the internal mechanism cannot level itself, the laser beams will ash indicating that the tilt range has been exceeded. THE FLASHING BEAMS CREATED BY THE LASER ARE NOT LEVEL OR PLUMB AND SHOULD NOT BE USED FOR DETERMINING OR MARKING LEVEL OR PLUMB. Try repositioning the laser on a more level surface. The Laser Beams Will Not Stop Moving The laser is a precision instrument. Therefore, if it is not positioned on a stable (and motionless) surface, the laser will continue to try to nd level. If the beam will not stop moving, try placing the laser on a more stable surface. Also, try to make sure that the surface is relatively at, so that the laser is stable. Service and Repairs Note: Disassembling the laser level will void all warranties on the product. To assure product SAFETY and RELIABILITY, repairs, maintenance and adjustment should be performed by authorized service centers. Service or maintenance performed by unqualied personnel may result in a risk of injury. To locate your nearest DeWALT service center, go to http://www.dewalt. com.15
