Operating Tips

• Use only new, high-quality, name-brand batteries for best results.
• Ensure batteries are in good working condition. If the low battery red indicator light is flashing, batteries need replacement.
• To extend battery life, turn the laser off when not working with or marking the beam.
• To ensure accuracy, check that your laser is calibrated often. See Field Calibration Check.
• Before use, ensure the laser is positioned securely on a smooth, flat surface.
• Always mark the center of the beam created by the laser.
• Extreme temperature changes may affect accuracy. Check your accuracy often while working. See Field Calibration Check.
• If the laser has been dropped, check its calibration. See Field Calibration Check.

Low Battery Indication

The DW086-XE and DW087-XE lasers have a red indicator light (B, located left of ON/OFF buttons C, D). A flashing red light indicates low batteries that need replacement. The beam may dim before the batteries are fully depleted. After replacing batteries, the beam will return to full brightness, and the light will turn off. (A flashing laser beam itself is not caused by low batteries; see Out of Tilt Range Indicator.)

Operation

To Turn the Lasers On and Off

• DW086-XE: Place the laser on a flat surface. Press the ON/OFF button (C) to power on the laser, projecting a horizontal line. Press the button again to turn it off.
• DW087-XE: Place the laser on a flat surface. This model has two ON/OFF buttons: one for a horizontal laser line (C) and one for a vertical laser line (D). Press the respective button to power each line on or off. Lines can be powered individually or simultaneously.

Using the Lasers

Beams are level or plumb if calibration has been checked and the laser beam is not flashing (indicating it is within the self-leveling range).

Out of Tilt Range Indicator

The DW086-XE and DW087-XE lasers self-level up to an average of 4° tilt. If tilted beyond this range, the laser beam will flash (as shown in diagrams). A flashing beam indicates the tilt range has been exceeded, and the beam is NOT level or plumb. Do not use it for determining or marking level or plumb. Reposition the laser on a more level surface.

Using the Lasers with Accessories

The lasers feature a 1/4" x 20 female thread on the bottom for DEWALT accessories. Use only DEWALT accessories specified for this product and follow their included instructions.

CAUTION: Using other accessories not recommended for this tool could be hazardous.

For assistance locating accessories, contact DEWALT Industrial Tool Co., 701 East Joppa Road, Baltimore, MD 21286, or call (AUS) 1800 654 155 or (NZ) 09 526 2556. See the catalog at www.dewalt.com.au.

Using the Pivot Bracket

The DW086-XE and DW087-XE lasers include a magnetic pivot bracket (E) for mounting to steel surfaces (e.g., framing studs, door frames, beams). The bracket also has a keyhole slot (F) for hanging from a nail or screw. Position the laser and/or wall mount on a stable surface to prevent falls.

Using the Laser with the Wall Mount

The DW0860 Laser Wall Mount offers additional mounting options. It features a clamp (G) for acoustic ceiling installation and a screw hole (H) for attachment to any surface. The wall mount's steel plate allows the magnetic pivot bracket to attach, enabling fine-tuning of the laser's position.

Leveling the Lasers

When properly calibrated, the lasers self-level on a flat surface within an average of ±4° of level. No manual adjustments are required.

Maintenance

• Regularly check the laser's calibration to maintain accuracy. See Field Calibration Check.
• Calibration checks and other maintenance repairs can be performed by DEWALT service centers.
• Store the laser in its kit box when not in use. Avoid storage temperatures below -20°C (-5°F) or above 60°C (140°F).
• Ensure the laser is dry before storing it in the kit box. Dry with a soft, dry cloth.

Cleaning

Clean exterior plastic parts with a damp cloth. Never use solvents. Use a soft, dry cloth to remove moisture before storage.

Field Calibration Check

Checking Accuracy – Horizontal Beam, Scan Direction (Figure 6)

Requires two walls 9 m (30') apart. Conduct check using a distance no shorter than intended application distance.

1. Attach laser to a wall, facing straight ahead.
2. Turn on the horizontal beam. Pivot the laser approximately 45° so the right-most end of the line strikes the opposing wall at least 9 m (30') away. Mark the beam center (a).
3. Pivot the laser approximately 90° so the left-most end of the line aligns with mark (a). Mark the beam center (b).
4. Measure the vertical distance between marks (a) and (b).
5. If the measurement exceeds the values below, the laser requires service at an authorized center.

Checking Accuracy – Horizontal Beam, Pitch Direction (Figure 7)

Requires a single wall at least 9 m (30') long. Conduct check using a distance no shorter than intended application distance.

1. Attach laser to one end of a wall, facing the opposite end and parallel to the adjacent wall.
2. Turn on the horizontal beam. Mark the beam center at two locations (c, d) at least 9 m (30') apart.
3. Reposition the laser to the opposite end of the wall.
4. Turn on the horizontal beam. Pivot back towards the first end, parallel to the adjacent wall.
5. Adjust laser height so the beam center aligns with the nearest mark (d).
6. Mark the beam center (e) directly above or below the farthest mark (c).
7. Measure the distance between marks (c) and (e).
8. If the measurement exceeds the values below, the laser requires service at an authorized center.

Checking Accuracy – Vertical Beam (DW087-XE Model Only)

Best done with substantial vertical height (ideally 9 m / 30'). One person on the floor positions the laser, another near the ceiling marks the beam. Conduct check using a distance no shorter than intended application distance (Figure 8).

1. Mark a 1.5 m (5') line on the floor.
2. Turn on the vertical beam. Position the unit at one end of the line, facing it.
3. Align and center the beam on the floor line.
4. Mark the beam center on the ceiling (f), directly over the floor line's midpoint.
5. Reposition the laser at the other end of the floor line. Align and center the beam on the line.
6. Mark the beam center on the ceiling (g), next to the first mark (f).
7. Measure the distance between marks (f) and (g).
8. If the measurement exceeds the values below, the laser requires service at an authorized center.

Troubleshooting

The Laser Does Not Turn On

• Ensure batteries are installed correctly (+ and -).
• Ensure batteries are in good working condition; try new batteries if in doubt.
• Check that battery contacts are clean and free of rust or corrosion. Keep the laser level dry and use only new, high-quality batteries.
• If the laser unit is heated above 50°C (120°F), it will not turn on. Allow it to cool before use.

The Laser Beams Flash

The DW086-XE and DW087-XE self-level up to 4° tilt. If tilted beyond this, the laser beam will flash, indicating the tilt range has been exceeded. Flashing beams are NOT level or plumb and should not be used for marking. Reposition the laser on a more level surface.

The Laser Beams Will Not Stop Moving

This can occur if the laser is not positioned on a stable, motionless surface. Try placing the laser on a more stable and relatively flat surface to ensure stability.
