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

Viewing the Battery Meter When the laser is ON, the battery meter on the keypad (Figure

) 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 fl 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

• 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, fl at stable surface that is level in both directions.

• To increase beam visibility, use a Laser Target Card (Figure

) and/or wear Laser Enhancement Glass es (Figure

) to help find the beam. 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.15

When the laser is not in use, slide the Power/Transport Lock switch to the left in the OFF/Locked position. If the Power/Transport Lock switch is not placed in the lock position, all 4 LEDs will continuously fl ash 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 fi 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, fl at, stable surface that is level in both directions.

• Mark the center of the laser beam. Horizontal Beam - Scan Direction Checking the horizontal scan calibration of the laser requires two walls 30′ (9m) 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.

Place the laser against the end of the wall on a smooth, fl at, stable surface that is level in both directions (Figure

Each laser is calibrated at the factory to fi nd level as long as it is positioned on a fl 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 fl ash. There are two fl ashing sequences associated with the out of level condition.

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

• At angles greater than 10° the beams fl ash with a three blink cycle. When the beams fl 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.18

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 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.

• The bracket has a keyhole slot (Figure

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

• 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 D EWALT service centers.
• When not in use, store the laser in the kit box provided. Do not store your laser at temperatures below -5˚F (-20˚C ) or above 140˚F (60˚C).

• Do not store your laser in the kit box if the laser is wet. The laser should be dried fi 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

• Make sure AA batteries (when used) are installed correctly according to + and – on the inside of the battery door.

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

• Make sure that the battery contacts are clean and free of rust or corrosion. Be sure to keep the laser level dry and use only new, high-quality, name brand batteries to reduce the chance of battery leakage.

• 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 fl 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 fi 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 fl at, so that the laser is stable.19

The Battery Meter LEDs Flash When all 4 LEDs continuously fl 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 (I) on the bottom of the unit (Figure

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

Since accessories, other than those offered by DEWalt, 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 D EWALT service center or go to www.DEWALT.com. 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 fi 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 fi ne-tuned by sliding the magnetic pivot bracket up or down on the wall mount.20
