If the Power/Transport Lock switch is not placed in the lock position, all 4 LEDs will continuously flash on the Battery Meter. 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, at, stable surface that is level in both directions.• Mark the center of the laser beam. Field Calibration Check Checking Accuracy – Horizontal Beam, Scan Direction (Fig. D) Checking the horizontal scan calibration of the laser requires two walls at least 30’ (9 m) apart. 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. Attach the laser to a wall using its pivot bracket. Make sure the laser is facing straight ahead.2. Turn on the laser’s horizontal beam and pivot the laser approximately 45˚ so that the right-most end of the laser line is striking the opposing wall at a distance of at least 30’ (9 m). Mark the center of the beam (a).3. Pivot the laser approximately 90˚ to bring the left-most end of the laser line around to the mark made in Step 2. Mark the center of the beam (b).4.

Using the Laser Leveling the Laser 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. If the laser has been tilted so much that it cannot self-level (> 4°), the laser beam will ash. There are two ashing sequences associated with the out of level condition.

• Between 4° and 10° the beams ash with a constant blink cycle

• At angles greater than 10° the beams ash with a three blink cycle. When the 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 more level surface. Using the Pivot Bracket The laser has a magnetic pivot bracket (Figure

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 a keyhole slot (Figure

) so it can be hung from a nail or screw on any kind of surface.

• The bracket has a ne adjustment knob (Figure

) to help you line up the laser beams. Place the unit on a at level surface and turn the knob to the right to move the beams to the right, or turn the knob to the left to move the beams to the left.

• The bracket has magnets (Figure

) 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. Before attaching the pivot bracket against a stud (Figure

) on the opposite side of the stud.21

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

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

• When not in use, store the laser in the kit box provided. Do not store your laser at temperatures below -20 ˚C or above 60 ˚C.

• Do not store your laser in the kit box if the laser is wet. The laser should be dried rst with a soft dry cloth prior to storage. Cleaning Exterior plastic parts may be cleaned with a damp cloth. Although these parts are solvent resistant, NEVER use solvents. Use a soft, dry cloth to remove moisture from the tool before storage. Troubleshooting The Laser Does Not Turn On

• Fully-charge the battery pack and then reinstall it in the laser unit.

• If the laser unit is heated above 120 ˚F (50 ˚C), 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 pressing the on/off button 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. The Battery Meter LEDs Flash When all 4 LEDs continuously ash on the Battery Meter this indicates that the unit has not been fully powered off using the Power/Transport Lock switch (Figure

). The Power/Transport Lock switch should always be placed in the LOCKED/OFF position when the laser is not in use. Accessories The laser is equipped with both 1/4 - 20 and 5/8 - 11 female threads on the bottom of the unit (Figure

This thread is to accommodate current or future DEWALT accessories. Only use DEWALT accessories specied for use with this product. Follow the directions included with the accessory.

Since accessories, other than those offered by D

WALT, have not been tested with this product, use of such accessories with this tool could be hazardous. To reduce the risk of injury, only DEWALT recommended accessories should be used with this product. If you need any assistance in locating any accessory, please contact your nearest DEWALT service center or go to www.2helpU.com.22

Target Card Some laser kits include a Laser Target Card (Figure

) to aid in locating and marking the laser beam. The target card enhances the visibility of the laser beam as the beam crosses over the card. The card is marked with standard and metric scales. The laser beam passes through the red plastic and reflects off of the reflective tape on the reverse side. The magnet at the top of the card is designed to hold the target card to ceiling track or steel studs to determine plumb and level positions. For best performance when using the Target Card, the DeWALT logo should be facing you. Laser Enhancement Glasses Some laser kits include Laser En hancement Glasses (Figure

). These glasses improve the visibility of the laser beam under bright light conditions or over long distances when the laser is used for interior applications. These glasses are not required to operate the laser. CAUTION: These glasses are not ANSI approved safety glasses and should not be used while operating other tools. These glasses do not keep the laser beam from entering your eyes. CAUTION: To reduce the risk of serious injury, never stare directly into the laser beam with or without these glasses. Ceiling Mount The laser ceiling mount (Figure

), if included, offers more mounting options for the laser. The ceiling mount has a clamp (Figure

) at one end which can be xed to a wall angle for acoustic ceiling installation (Figure

). At each end of the ceiling mount is a screw hole (Figure

), allowing the ceiling mount to be attached to any surface with a nail or screw. Once the ceiling mount is secured, its steel plate provides a surface to which the magnetic pivot bracket (Figure

) 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.
