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 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, Baltimore, MD 21286 or call 1-800-4-DeWALT (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.

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.

CHECKING ACCURACY – VERTICAL BEAM (FIG. 8)

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.

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 (f). 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 (g), directly beside the first mark (f).

7. Measure the distance between these two marks.

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

service center.
