After fresh batteries are installed and the laser is turned on again, the laser beam(s) will return to full brightness and the indicator lights will stay off. (A flashing laser beam is not caused by low batteries; see Out of Tilt Range Indicator.)

OPERATING TIPS

• To extend battery life, 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.

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.

To Turn the Laser On and Off (Fig. C, D)

1. Unlock unit by sliding Lock/Power-Unlock bar 6 to the right.
2. With the laser off, place it on a flat surface. This model has three ON/OFF buttons, one for a horizontal laser line 3, one for a vertical laser line 4, and one for the plumb laser spots 5.

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. E)

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.

Distance Between Walls	Allowable Distance Between a and b
30' 1/8"
40' 5/32"
50' 7/32"

Distance Between Walls	Allowable Distance Between a and b
9.0 m 3.1 mm
12.0 m 4.2 mm
15.0 m 5.2 mm

Checking Accuracy - Horizontal Beam, Pitch Direction (Fig. F)

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.

Distance Between Walls	Allowable Distance Between a and b
30' 1/4"
40' 5/16"
50' 13/32"

Distance Between Walls	Allowable Distance Between a and b
9.0 m 6.2 mm
12.0 m 8.3 mm
15.0 m 10.4 mm

Checking Accuracy - Vertical Beam (Fig. G)

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.

ENGLISH

1. Mark the position of the laser beam on the ceiling (b), directly beside the first mark (a).
2. 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.

Distance Between Walls	Allowable Distance Between a and b
8' 1/8"
10' 3/16"
14' 1/4"
20' 3/8"

Distance Between Walls	Allowable Distance Between a and b
2.5 m 3.4 mm
3.0 m 4.2 mm
4.0 m 5.5 mm
6.0 m 8.2 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. 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 (Fig. H, I)

The laser has a magnetic pivot bracket 7 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 keyhole slot 8 so it can be hung from a nail or screw on any kind of surface.

- The bracket has magnets 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.

Using the Lasers with Accessories

The lasers are equipped with a 1/4" x 20 female thread on the bottom of the unit. 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.

CAUTION: The use of any other accessory not recommended for use with this tool could be hazardous.

If you need any assistance in locating any accessory, please contact DEWALT Industrial Tool Co., 701 East Joppa Road, Towson, MD 21286 or call 1–800–4-DEWALT (1–800–433–9258). See our catalog on the World Wide Web at www.DEWALT.com.

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

- Remove the batteries and replace with fresh batteries. Ensure the battery contacts are free of corrosion.

English

- 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 (Fig. J)

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.
