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 the laser off when not working with or marking the beam.
To ensure the accuracy of your work, check often to make sure your laser is calibrated. 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 DW089 laser is equipped with a red indicator light (B), as shown in Figure 2. The red indicator light is located to the left of the on/off buttons (C, D, E). 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 Laser On and Off (Fig. 2)
With the laser off, place it on a flat surface. This model has three ON/OFF buttons, one for a horizontal laser line (C), one for a vertical laser line (D) and one for a side vertical laser line (E). 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 Laser

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) The DW089 laser is 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. 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.
SLOPING THE LASER
If the DW089 laser is tilted beyond 15° out of level, its laser beams will stay on longer between flashes to make it easier to do angled work.
USING THE PIVOT BRACKET (FIG. 2)
WARNING: 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.
The DW089 laser has a magnetic pivot bracket (F) permanently attached to the unit. 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 (G) allowing the unit to be hung from a nail or screw on any kind of surface.
USING THE LASER WITH THE WALL MOUNT (FIG. 4) The laser wall mount (J) offers more mounting options for the DW089 laser. The wall mount has a clamp (K) at one end which can be fixed to a wall angle for acoustic ceiling installation. At each end of the wall mount is a screw hole (L), 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 (F) can be attached. The position of the laser can then be fine-tuned by sliding the magnetic pivot bracket up or down on the wall mount.
ALIGNING THE VERTICAL BEAM – FINE ADJUST (FIG. 5) The fine adjustment knob (H) on the top of the DW089 is for lining up the vertical beams. Place the DW089 on a flat surface and turn the knob to the right to move the beam to the right or to the left to move the beam to the left.
Rotating the fine adjustment knob adjusts the entire internal mechanism, maintaining the 90° angle between the two vertical beams.
LEVELING THE LASER
As long as the DW089 laser is properly calibrated, the laser is self- leveling. Each laser is calibrated at the factory to find level as long as it is positioned on a flat surface within an average ± 4° of level. No manual adjustments are required.

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°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.

Attach the laser to a wall using its pivot bracket, with the laser facing straight ahead toward the opposing wall (0 degree position).
Turn on the laser’s horizontal beam and mark the beam position on the opposing wall directly across from the laser. Always mark the center of the beam’s thickness.
Pivot the laser to the extreme left (-90 degree position) and mark the beam position on the opposing wall.
Pivot the laser to the extreme right (+90 degree position) and mark the beam position on the opposing wall.
Measure the vertical distance between the lowest mark (A) and the highest mark (B). 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′ (9.0m)| 1/4″ (6.0mm)
40′ (12.0m)| 5/32″ (8.0mm)
50′ (15.0m)| 7/32″ (10.0mm)

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.

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′ (9m) 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 Marks
---|---
30′ (9.0m)| 1/4″ (6.0mm)
40′ (12.0m)| 5/16″ (8.0mm)
50′ (15.0m)| 13/32″ (10.0mm)

CHECKING ACCURACY – VERTICAL BEAMS (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.

Place the laser on the floor and turn on both vertical beams.
Mark the position where the beams cross on the floor (F) and also on the ceiling (G). Always mark the center of the beams’ thickness.
Rotate the laser 180 degrees, and reposition it so the beam crossing is exactly on the original mark (F) on the floor.
Mark the position where the beams cross on the ceiling (H).
Measure the distance between the two ceiling marks (G, H). If the measurement is greater than the values shown below, the laser must be serviced at an authorized service center.
Ceiling Height| Allowable Distance Between Marks
---|---
8′ (2.5m)| 1/16″ (1.5mm)
10′ (3.0m)| 3/32″ (2.0mm)
14′ (4.0m)| 1/8″ (2.5mm)
20′ (6.0m)| 5/32″ (4.0mm)
30′ (9.0m)| 1/4″ (6.0mm)

CHECKING 90º ACCURACY BETWEEN VERTICAL BEAMS (FIG. 9)
Checking 90º accuracy requires an open floor area at least 33′ x 18′ (10m x 5m). Refer to Figure 9 for the position of the DW089 at each step and for the location of the marks made at each step. Always mark the center of the beams’ thickness.

Set up the laser in one corner of the floor and turn on the forward vertical beam.
Mark the center of the beam at three locations (A, B and C) on the floor along the laser line.
Mark B should be at the midpoint of the laser line.
Move the laser to mark B and turn on both vertical beams.
Position the beam crossing precisely at mark B, with the forward beam aligned with mark C.
Mark a location (D) along the side vertical beam at least 18′ (5m) away from the unit.
Rotate the laser over mark B so that the forward vertical beam now passes through mark D.
Mark the location (E) where the side vertical beam passes by mark A.
Measure the distance between marks A and E. If the measurement is greater than the values shown below, the laser must be serviced at an authorized service center.

Distance from A to B	Allowable Distance Between Marks
14′ (4.0m)	5/32″ (3.5mm)
17′ (5.0m)	3/16″ (4.5mm)
20′ (6.0m)	7/32″ (5.5mm)
23′ (7.0m)	1/4″ (6.0mm)

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 122°F (50°C), 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
The DW089 is designed to self-level up to an average of 4° in all directions when positioned as shown in Figure 3. If the laser is tilted so much that the internal mechanism cannot level itself, it will flash the laser beams – 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 DW089 is a precision instrument. 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.
