The use of any other batteries may create a risk of fire.

Charging the Li-ion Battery

If the DEWALT 12V/18V 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 ).
Plug the charger cord into an electrical outlet.
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.
After the battery is fully charged (the indicator light on the charger no longer flash), press and hold the release button on the battery pack (Figure
A 2 ) and slide the pack out of the charger (Figure A 3 ).
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 7 ) indicates how much power remains.

The bottom LED will illuminate and flash when the battery level is low (10%). 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/18V 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 M ) and/or wear Laser Enhancement Glasses (Figure N ) 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.

Turning the Laser On
Place the laser on a flat level surface. Slide the Power/Transport Lock switch C 2 to the right to unlock/turn ON the laser.
Each laser line is powered by pressing its button on the keypad (Figure C 3 ). Pressing the button again turns the laser line off. The laser lines can be powered one at a time or all at the same time.

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 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.

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, flat, stable surface that is level in both directions (Figure D 1 ).
Move the Power/Transport Lock switch to the right to turn the laser ON.
Press to turn on the horizontal beam.
At least 30′ (9m) apart along the laser beam, mark a and b.
Turn the laser 180º.
Adjust the height of the laser so the center of the beam is aligned with a (Figure D 2 ).
Directly above or below b, mark c along the laser beam (Figure D 3 ).
Measure the vertical distance between b and c.
If your measurement is greater than the Allowable Distance Between b and c for the corresponding Distance Between Walls in the following table, the laser must be serviced at an authorized service center.

Distance

Between 0 and 0
---|---
10.0 m| 6.0 mm
12.0 m| 7.2 mm
15.0 m| 9.0 mm

Horizontal Beam – Pitch Direction
Checking the horizontal pitch calibration of the laser requires a single wall at least 30′ (9m) 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.

Place the laser against the end of the wall on a smooth, flat, stable surface that is level in both directions (Figure E 1 ).
Move the Power/Transport Lock switch to the right to turn the laser ON.
Press to turn on the horizontal beam.
At least 30′ (9m) apart along the laser beam, mark a and b.
Move the laser to the opposite end of the wall (Figure E 2 ).
Position the laser toward the first end of the same wall and parallel to the adjacent wall.
Adjust the height of the laser so the center of the beam is aligned with b.
Directly above or below a mark c along the laser beam (Figure E 3 ).
Measure the distance between a and c.
If your measurement is greater than the Allowable Distance Between a and c for the corresponding Distance Between Walls in the following table, the laser must be serviced at an authorized service center.

Distance
Between Walls| Allowable Distance
Between 0 and 43
---|---
10.0 m| 6.0 mm
12.0 m| 7.2 mm
15.0 m| 9.0 mm

Vertical Beam
Checking the vertical (plumb) calibration of the laser can be most accurately done when there is a substantial amount of vertical height available, ideally 30’ (9m), 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.

Place the laser on a smooth, flat, stable surface that is level in both directions (Figure F 1 ).
Move the Power/Transport Lock switch to the right to turn the laser ON.
Press and to turn on both vertical beams.
Mark two short lines where the beams cross a, b, and also on the ceiling c, d. Always mark the center of the beam’s thickness (Figure F 2 ).
Pick up and rotate the laser 180º, and position it so the beams line up with the marked lines on the level surface ( e , f ) (Figure F 3 ).
Mark two short lines where the beams cross on the ceiling g, h.
Measure the distance between each set of marked lines on the ceiling ( c, g, and d, h ). If the measurement is greater than the values shown below, the laser must be serviced at an authorized service center.

Ceiling Height| Allowable Distance
Between Marks
---|---
2.5 m| 1.7 mm
3.0 m| 2.1 mm
4.0 m| 2.8 mm
6.0 m| 4.1 mm
9.0 m| 6.2 mm

90º Accuracy Between Vertical Beams
Checking 90º accuracy requires an open floor area of at least 33’ x 18’ (10m x 5m). Refer to Figure G for the position of the laser at each step and for the location of the marks made at each step. Always mark the center of the beam’s thickness.

Place the laser on a smooth, flat, stable surface that is level in both directions.
Move the Power/Transport Lock switch to the right to turn the laser ON.
Press to turn on the side vertical beam.
Mark the center of the beam at three locations ( a, b, c ) on the floor along the side laser line. Mark b should be at the midpoint of the laser line (Figure G 1 ).
Pick up and move the laser to b .
Press to turn on the front vertical beam too (Figure G 2 ).
Position the front vertical beam so it crosses precisely at b, with the side beam aligned with c (Figure G 2 ).
Mark a location e along the front vertical beam at least 14’ (4m) away from the unit (Figure G 2 ).
Rotate the laser 90º so the side vertical beam now passes through b and e (Figure G 3 ).
Directly above or below a mark f along the front vertical beam.
Measure the distance between a and f . If the measurement is greater than the values shown below, the laser must be serviced at an authorized service center.

Distance from
a to b| Allowable Distance
Between a and f
---|---
4.0 m| 3.5 mm
5.0 m| 4.4 mm
6.0 m| 5.3 mm
7.0 m| 6.2 mm

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 H 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 a fine adjustment knob (Figure H 2 ) to help you line up the laser beams. Place the unit on a flat 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 a keyhole slot (Figure I ) so it can be hung from a nail or screw on any kind of surface.
The bracket has magnets (Figure J 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 J 2 ), place the Metal Enhancement Plate (Figure J 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 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 K ).
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, the 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.

Target Card
Some laser kits include a Laser Target Card (Figure M ) 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 a 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 N ). 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:
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 L 1 ), if included, offers more mounting options for the laser. The ceiling mount has a clamp (Figure L 2 ) at one end which can be fixed to a wall angle for acoustic ceiling installation (Figure L 3 ). At each end of the ceiling, the mount is a screw hole (Figure L 4 and L 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 L 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.
