Viewing the Battery Meter

When the laser is ON, the battery meter on the keypad (Figure ⑦) 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 flash 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 ⑤②).

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, fl at stable surface that is level in both directions.
- To increase beam visibility, use a Laser Target Card (Figure D) and/or wear Laser Enhancement Glass es (Figure E) 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.

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 find level as long as it is positioned on a flat 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 flash with a constant blink cycle
• At angles greater than 10^ the beams flash with a three blink cycle.

When the beams flash 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.

E Using the Pivot Bracket

The laser has a magnetic pivot bracket (Figure ⑤ ①) permanently attached to the unit.

WARNING:

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 ①②) 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 ⑤② or ⑥①) 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 DEWALT 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 first 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 flat, so that the laser is stable.

The Battery Meter LEDs Flash

When all 4 LEDs continuously flash on the Battery Meter this indicates that the unit has not been fully powered off using the Power/Transport Lock switch (Figure F②). 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 ①). This thread is to accommodate current or future DeWalt accessories. Only use DeWalt accessories specified for use with this product. Follow the directions included with the accessory.

WARNING:

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 DeWALT service center or go to www.DEWALT.com.

Target Card

Some laser kits include a Laser Target Card (Figure ①) 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 DrWALT logo should be facing you.

Laser Enhancement Glasses

Some laser kits include Laser En hancement Glasses (Figure E). 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 ①①), if included, offers more mounting options for the laser. The ceiling mount has a clamp (Figure ②②) at one end which can be fixed to a wall angle for acoustic ceiling installation (Figure ③③). At each end of the ceiling mount is a screw hole (Figure ④④ and ⑤⑤), 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 ①⑥) can be attached. The position of the laser can then be fine-tuned by sliding the magnetic pivot bracket up or down on the wall mount.
