Except for batteries, there are no user serviceable parts in the Digital Laser Detector. Do not disassemble the unit. Unauth orized tampering with the laser detector will void all warranties.

Detector Troubleshooting

THE DETECTOR WILL NOT TURN ON.

- Press and release the power button.

- Check to see that the battery is in place and in the proper position.

• If the detector is very cold, allow it to warm up in a heated area.
• Replace the 9-volt battery. Turn the unit on.
• If the detector still does not turn on, take the detector to a DEWALT service center.

THE DETECTOR'S SPEAKER MAKES NO SOUND.

- Ensure that the detector is on.

• Press the volume button. It will toggle from high, to low, to mute.
• Ensure that the rotary laser is spinning and that it is emitting a laser beam.
• If the detector is still not making any sound, take it to a D EWALT service center.

THE DETECTOR DOES NOT RESPOND TO A STATIONARY LASER BEAM.

- The BWALT Digital Laser Detector has been designed to work only with rotary lasers.

THE DETECTOR GIVES OFF A TONE BUT THE LCD DISPLAY WINDOW DOES NOT FUNCTION.

• If the detector is very cold, allow it to warm up in a heated area.
• If the LCD display window is still not functioning, take the detector to a DEWALT service center.

Construction Grade Rod

▲DANGER: NEVER attempt to use a grade rod in a storm or near overhanging electric wires. Death or serious personal injury will occur.

Some laser kits include a grade rod. The DEWALT Grade Rod is marked with measurement scales on both sides and is constructed

in telescoping sections. A spring-loaded button actuates a lock to hold the grade rod at various lengths.

The front of the grade rod has the measurement scale starting at the bottom. Use this for measuring from the ground up when grading or leveling jobs.

The back of the grade rod is designed to measure the height of ceilings, joists, etc. Fully extend the top section of the grade rod until the button locks into the previous section. Extend that section

either until it locks into the adjacent section or until the grade rod touches the ceiling or joist. The height is read where the last extended section exits the previous lower section, as shown in Figure 11.

FIG. 11

Using the Laser with a Wall Mount (Fig. 12)

Some laser kits include a Wall Mount. It can be used for attaching the tool to track or ceiling angle and to aid in acoustical ceiling installation. Follow the directions below for using the wall mount.

CAUTION: Before attaching the laser level to wall track or ceiling angle, be sure that the track or angle is properly secured.

1. Place the laser on the mounting base (X) aligning the hole (Y) on the bottom of the laser with the hole (Z) in the mounting base. Place rear rubber foot into the mounting base slot (AA). Turn the mounting knob (BB) to secure the laser.
2. With the wall mount measuring scale (CC) facing you, push the clamp lever (DD) in to open the clamp jaws (EE).
3. Position the clamp jaws (EE) around the wall track or ceiling angle and release the clamp lever (DD) to close the clamp

jaws on the track. Be sure that the wall mount is secure before proceeding.

CAUTION: Always use a ceiling wire hanger or equivalent material, in addition to the wall mount clamp locking knob, to help secure the laser level while mounting it to a wall. Thread the wire through the handle of the laser level. DO NOT thread the wire through the protective roll cage. Additionally, screws may be used to fasten the wall mount directly to the wall as a back up. A screw holes (FF) is located at the top of the wall mount.

FIG. 12 X → Z AA EE GG CC BB DD FF EE Y

1. The tool can be adjusted up and down to the desired offset height for working. To change the height, loosen the locking knob (GG) located on the side of the wall mount to move the laser level up and down to the desired height. Support the mounting base when adjusting the height.

2. Use the wall mount measuring scale (CC) to pinpoint your mark.

NOTE: It may be helpful to turn the power on and turn the rotary head so that it puts a dot on one of the laser scales. The DEWALT target card is marked at 1-1/2" (38 mm), therefore, it may be easiest to set the offset of the laser to 1-1/2" (38 mm) below the track.

1. Once you have positioned the laser at the desired height, tighten the locking knob (GG) to maintain this position.

LASER MAINTENANCE

- Under some conditions, the glass lens inside the rotary head may collect some dirt or debris. This will affect beam quality and operating range. The lens should be cleaned with a cotton swab moistened with water as shown in Figure 13.

- The flexible rubber shield can be cleaned with a wet lint-free cloth such as a cotton cloth. USE WATER ONLY — DO NOT use cleansers or solvents. Allow the unit to air dry before storing.

• To maintain the accuracy of your work, check the calibration of the laser often. Refer to Field Calibration Check.

- Calibration checks and other maintenance repairs can be performed by DEWALT service centers. Two free calibration checks are included under the DEWALT One Year Free Service Contract.

- When the laser is not in use, store it in the kit box provided.

FIG. 13

- Do not store your laser in the kit box if the laser is wet. Dry exterior parts with a soft, dry cloth and allow the laser to air dry.

- Do not store your laser at temperatures below 0°F (-18°C) or above 105°F (41°C).

⚠ WARNING: Never use solvents or other harsh chemicals for cleaning the non-metallic parts of the tool. These chemicals may weaken the materials used in these parts. Use a cloth dampened only with water and mild soap. Never let any liquid get inside the unit; never immerse any part of the unit into a liquid. Never use compressed air to clean the laser.

Field Calibration Check (Fig. 14-16)

Field calibration checks should be done frequently. This section provides instructions for performing simple field calibration checks of your DEWALT Rotary Laser. Field calibration checks do not calibrate the laser. That is, these checks do not correct errors in the leveling or plumbing capability of the laser. Instead, the checks indicate whether or not the laser is providing a correct level and plumb line. These checks cannot take the place of professional calibration performed by a DEWALT service center.

LEVEL CALIBRATION CHECK (X-AXIS)

FIG. 14 Y-AXIS

1. Set up a tripod between two walls that are at least 50 feet (15.3 m) apart. The exact location of the tripod is not critical.

2. Mount the laser unit on the tripod so that the X-axis points directly toward one of the walls.

3. Turn the laser unit on and allow it to self-level.

4. Mark and measure points A and B on the walls as shown in Figure 15.

FIG. 15 BEAM A B L

1. Turn the entire laser unit 180° so the X-axis points directly toward the opposite wall.
2. Allow the laser unit to self-level, and mark and measure points AA and BB on the walls as shown in Figure 16.

FIG. 16 LASER UNIT ROTATED 180° BEAM AA L BB

1. Calculate the total error using the equation:

Total Error = (AA - A) - (BB - B)

1. Compare total error to the allowable limits shown in the following table.

Distance between walls	Allowable Error
L = 50 ft. (15.3 m) 1/4"	(6 mm)
L = 75 ft. (22.9 m) 3/8"	(9 mm)
L = 100 ft. (30.5 m) 1/2"	(12 mm)

LEVEL CALIBRATION CHECK (Y-AXIS)

Repeat the procedure above, but with the laser unit positioned so the Y-axis is pointed directly toward the walls.

PLUMB ERROR CHECK (FIG. 17)

1. Using a standard plumb bob as a reference, mark the top and bottom of a wall (Be sure to mark the wall and not the floor and ceiling.)
2. Position the rotary laser securely on the floor approximately 1 m (3 ft.) from the wall.
3. Turn the laser on and level it using the arrow buttons to center the bubble. Put the unit in low speed rotation for maximum visibility, making sure the beam passes through the mark on the bottom of the wall. Recheck the bubble position to confirm it is still centered.
4. If the center of the beam lines up with the marks at the bottom and top of the wall, the laser is properly calibrated.

NOTE: This check should be done with a wall no shorter than the allest wall for which this laser will be used.
