Charging the Li-ion Battery

❶ If the DeWALT 12V/20V MAX* Li-ion battery pack is attached to the laser, remove it.
• While pressing down on the release button on the battery pack (Figure B 1 ), pull the battery pack up to unlock it from the laser.
• Pull the battery pack the rest of the way up and out of the laser (Figure B 2 ).
❷ Plug the charger cord into an electrical outlet.
❸ Slide the battery pack into the charger until it snaps in place (Figure A 1 ). On the charger, the left indicator light will flash to let you know the battery is being charged.
❹ 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 A 2 ) and slide the pack out of the charger (Figure A 3 ).
❺ Slide the battery pack down in the laser until it snaps in place (Figure A 4 ).

Viewing the Battery Meter

When the laser is ON, the battery meter on the keypad (Figure C 9 ) 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 the 12V/20V 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 C 2 ).
  

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 L ) and/or wear Laser Enhancement Glasses (Figure M ) 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 C hecking Laser Accuracy

Turning the Laser On

With the laser off, place it on a flat surface. This model has a pendulum locking switch 2 and a keypad 9 to activate the laser beams with two ON/OFF buttons; one for a horizontal laser line and one for a vertical laser line . Each laser line is powered on by moving the pendulum lock switch 2 to the UNLOCKED/ON position and pressing the required ON/OFF button on the keypad. The laser lines can be powered one at a time or at the same time. Pressing the ON/OFF buttons again turns the laser lines off. The pendulum locking switch disables the lasers as well as locking the pendulum, and should always be placed in the LOCKED/OFF position when the laser is not in use.

If the pendulum lock switch is not placed in the lock position all 4 LED’s 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, flat, 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. Measure the vertical distance between the marks.

• If the measurement is greater than the values shown below, the laser must be serviced at an authorized service center.

Checking Accuracy – Horizontal Beam, Pitch Direction (Fig. E)

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. Attach the laser to one end of a wall using its pivot bracket.
2. Turn on the laser’s horizontal beam and pivot the laser toward the opposite end of the wall and approximately parallel to the adjacent wall.
3. Mark the center of the beam at two locations (a, b) at least 30′ (9m) apart.
4. Reposition the laser to the opposite end of the wall.
5. Turn on the laser’s horizontal beam and pivot the laser back toward the first end of the wall and approximately parallel to the adjacent wall.
6. Adjust the height of the laser so that the center of the beam is aligned with the nearest mark (b).
7. Mark the center of the beam (c) directly above or below the farthest mark (a).
8. Measure the distance between these two marks (a, c)

• If the measurement is greater than the values shown below, the laser must be serviced at an authorized service center.

Checking Accuracy – Vertical Beam (Fig. F)

Checking the vertical (plumb) calibration of the laser can be most accurately done when there is a substantial amount of vertical height available, ideally 20′ (6 m), with one person on the floor positioning the laser and another person near a ceiling to mark the position of the beam. 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. Start by marking a 5′ (1.5 m) line on the floor.
2. Turn on the laser’s vertical beam and position the unit at one end of the line, facing the line.
3. Adjust the unit so its beam is aligned and centered on the line on the floor.
4. Mark the position of the laser beam on the ceiling (a). Mark the center of the laser beam directly over the midpoint of the line on the floor.
5. Reposition the laser at the other end of the line on the floor. Adjust the unit once again so its beam is aligned and centered on the line on the floor.
6. Mark the position of the laser beam on the ceiling (b), directly beside the first mark (a).
7. Measure the distance between these two marks.

• If the measurement is greater than the values shown below, the laser must be serviced at an authorized service center.
• Ceiling Allowable Distance Between Marks Height 8′

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 flash. There are two flashing 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.

Using the Pivot Bracket

The laser has a magnetic pivot bracket (Figure G 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.

1. The bracket has a keyhole slot (Figure H ) so it can be hung from a nail or screw on any kind of surface.
   • The bracket has magnets (Figure I 1 ) 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 I 2 ), place the Metal Enhancement Plate (Figure I 3 ) on the opposite side of the stud.
   
   

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

• 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 flash 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 find 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 C 2 ). 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 J ). 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 thisproduct, 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 L ) 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 Enhancement Glasses (Figure M ). 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 K 1 ), if included, offers more mounting options for the laser. The ceiling mount has a clamp (Figure K 2 ) at one end which can be fixed to a wall angle for acoustic ceiling installation (Figure K 3 ). At each end of the ceiling mount is a screw hole (Figure K 4 and K 5 ), 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 K 6 ) 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.
