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 movement 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 DW088 lasers are equipped with a red indicator light 2, as shown in Fig. B. The red indicator lights are located to the left of the on/off buttons (3, 4).

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. B)

With the laser off, place it on a flat surface. This model has two ON/OFF buttons, one for a horizontal laser line 3 and one for a vertical laser line 4. 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. C, D)

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. D). 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, 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.

Using the Pivot Bracket (Fig. E)

The lasers have a magnetic pivot bracket 5 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 6 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. E)

The DW0860 Laser Wall Mount offers more mounting options for the DW088 lasers. The wall mount has a clamp 7 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 8, 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

s long as the lasers are properly calibrated, the lasers are selfleveling. 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 DeWALT service centers.
When not in use, store the laser in the kit box provided. Do not store your laser at temperatures below -5 ºF (-20 ºC) or above 140 ºF (60 ºC).
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. F)

Checking the horizontal scan calibration of the laser requires two walls 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.

Attach the laser to a wall using its pivot bracket. Make sure the laser is facing straight ahead.
Turn on the laser’s horizontal beam and pivot the laser approximately 45º 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 beamo (a).
Pivot the laser approximately 90º 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).
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 Marks
30’ (9 m)	1/8” (3.0 mm)
40’ (12 m)	5/32” (4.0 mm)
50’ (15 m)	7/32” (5.0 mm)

Checking Accuracy – Horizontal Beam, Pitch Direction (Fig. G)

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.

Attach the laser to one end of a wall using its pivot bracket.
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.
Mark the center of the beam at two locations (c, d), at least 30’ (9 m) apart.
Reposition the laser to the opposite end of the wall.
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.
Adjust the height of the laser so that the center of the beam is aligned with the nearest mark (d).
Mark the center of the beam (e) directly above or below the farthest mark (c).
Measure the distance between these two marks (c, e).
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 Markss
30’ (9 m)	1/4” (6.0 mm)
40’ (12 m)	5/16” (8.0 mm)
50’ (15 m)	13/32” (10.0 mm)

Checking Accuracy – Vertical Beam (Fig. H)

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’ (9 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.

Start by marking a 5’ (1.5 m) line on the floor.
Turn on the laser’s vertical beam and position the unit at one end of the line, facing the line.
Adjust the unit so its beam is aligned and centered on the line on the floor.
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.
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.
Mark the position of the laser beam on the ceiling (g), directly beside the first mark (f).
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.

Ceiling Allowable Distance	Between Marks Height
8’ (2.5 m)	5/32 (3,5 mm)
10’ (3.0 m)	3/16 (4,5 mm)
14’ (4.0 m)	1/4 (6,0 mm)
20’ (6.0 m)	3/8 (9,0 mm)
30’ (9.0 m)	1/2 (13 mm)

TROUBLESHOOTING

The Laser Does Not Turn On

Make sure batteries are installed according to (+) and (–) on the inside of the battery door.
Make sure the batteries are in proper working condition. If in doubt, try installing new batteries.
Make sure that the battery contacts are clean and free of rust or corrosion. Be sure to keep the laser level dry and use only new, high-quality, name brand batteries to reduce the chance of battery leakage.
If the laser unit is heated above 120 ºF (50 ºC), 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. C, D)

The DW088 lasers have been designed to self-level up to an average of 4° in all directions when positioned as shown in Fig. C. If the laser is tilted so much that internal mechanism cannot level itself, it will flash the laser (Fig. D) – 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 DW088 lasers are precision instruments. Therefore, if the laser 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.
