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, the batteries need replacement.
•
To extend battery life, turn laser off when not working with or marking the beam.
•
To ensure the accuracy of your work, check to make sure your laser is calibrated often. See Field Calibration Check.
•
Before attempting to use the laser, make sure it is positioned securely, on a smooth, flat surface.
•
Always mark the center of the beam created by the laser.
•
Extreme temperature changes may cause movememt of internal parts that can affect accuracy.Check your accuracy often while working. See Field Calibration
Check.
•
If the laser has been dropped, check to make sure your laser is still calibrated. See Field Calibration Check.
LOW BATTERY INDICATION
The DW087 and DW088 lasers are equipped with a red indicator light (B), as shown in Figure 2. The red indicator lights are located to the left of the ON/OFF buttons
(C, D).
A flashing red indicator light indicates that the batteries are low and need to be replaced. The laser may continue to operate for a short time while the batteries
continue to drain, but the beam(s) will quickly dim. After fresh batteries are installed and the laser is turned on again, the laser beam(s) will return to full brightness
and the red indicator light will stay off. (A flashing laser beam is not caused by low batteries; see Out of Tilt Range Indicator.)

OPERATION
To Turn the Lasers On and Off (Fig. 2)
With the laser off, place it 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). Each laser line is
powered on by pressing its ON/OFF button. 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.
Using the Lasers
The beams are level or plumb as long as the calibration has been checked (see Field Calibration Check) and the laser beam is not flashing (see Out of Tilt Range
Indicator).
OUT OF TILT RANGE INDICATOR (FIG. 3, 4)
The lasers are designed to self-level. If the laser has been tilted so much that it cannot level itself (average > 4° tilt), it will flash the laser beam (Fig. 4). The flashing
beam indicates the tilt range has been exceeded and 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 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 D

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 D
(1-800-433-9258). See our catalog on the World Wide Web at www.dewalt.com.
USING THE PIVOT BRACKET (FIG. 5)
The lasers have a magnetic pivot bracket (E) permanently attached to the units. This bracket allows the unit to be mounted to any upright surface made of steel or iron.
Common examples of suitable surfaces include steel framing studs, steel door frames and structural steel beams. The bracket also has a keyhole slot (F) allowing the
unit to be hung from a nail or screw on any kind of surface. 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.
USING THE LASER WITH THE WALL MOUNT (FIG. 5)
The DW0860 Laser Wall Mount offers more mounting options for the DW087 and DW088 lasers. The wall mount has a clamp (G) at one end which can be fixed to a wall
angle for acoustic ceiling installation. At the other end of the wall mount is a screw hole (H), allowing the wall mount to be attached to any surface with a nail or screw.
Once the wall mount is secured, its steel plate provides a surface to which the magnetic pivot bracket can be attached. The position of the laser can then be fine-tuned
by sliding the pivot bracket up or down on the wall mount.
LEVELING THE LASERS
As long as the lasers are properly calibrated, the lasers are 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 must be made.
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 D
• 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.
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.
Field Calibration Check
CHECKING ACCURACY – HORIZONTAL BEAM, SCAN DIRECTION (FIG. 6)
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.
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' (9m). 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.
5. If the measurement is greater than the values shown below, the laser must be serviced at an authorized service center.
