Maintenance; Field Calibration Check - DeWalt DW087 Instruction Manual

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 WALT accessories. Only use D
e
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 D
Road, Baltimore, MD 21286 or call 1-800-4-D
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
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.
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.

CHECKING ACCURACY – HORIZONTAL BEAM, PITCH DIRECTION (FIG. 7)
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.
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 (c, d) 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 approxi-
mately 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 (d).
7. Mark the center of the beam (e) directly above or below the farthest mark (c).
8. Measure the distance between these two marks (c, e).
9. If the measurement is greater than the values shown below, the laser must be serviced at an authorized
service center.

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.
1. Start by marking a 5' (1.5m) 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 (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.
