DIGITAL LASER DETECTOR (FIG. 4)

The detector helps in locating the position of a laser beam in bright light conditions or over long distances. It produces both visual and audio signals as the rotating laser beam crosses the detector.

The detector can be used both indoor and outdoor whenever it is difficult to locate the laser beam.

The detector is not for use with non-rotating lasers but is compatible with most rotary red-beam or infrared (invisible) beam lasers on the market.

The DEWALT Digital Laser Detector can be used with or without the detector clamp. When used

with the clamp, the detector can be positioned on a grade rod, leveling pole, stud or post.

Accuracy

When the laser is operated using the detector, the accuracy level of the detector needs to be added to that of the laser.

• Constant accuracy (detector in narrow setting) ± 1.0 mm

- Nominal accuracy (detector in wide setting) ± 3.0 mm

For most accurate results, start the operation using the wide setting and finish in the narrow setting.

Mounting Detector on a Grade Rod (fig. 4)

1. To secure your detector to a grade rod, first attach the detector to the clamp by pushing in on the clamp latch (u). Slide the tracks (v) on the clamp around the rail (w) on the detector until the latch (x) on the clamp pops into the latch hole (y) on the detector.
2. Open the jaws of the clamp by turning the clamp knob (z) counterclockwise.
3. Position the detector at the height needed and turn the clamp knob clockwise to secure the clamp on the rod.
4. To make adjustments in height, slightly loosen the clamp, reposition and retighten.

WARNING: Always have the laser head calibrated by a qualified repair agent.

Field calibration checks should be done frequently.

NOTE: As part of the DEWALT guarantee, the owner is entitled to one FREE calibration service within the first year. Simply complete the enclosed voucher and return along with the laser and proof of purchase to an authorised DEWALT agent. A certificate will be awarded at no additional charge.

Field calibration checks do not calibrate the laser. These checks indicate whether or not the laser is providing a correct level line and do not correct errors in the leveling capability of the laser.

These checks cannot take the place of professional calibration performed by a DeWALT service centre.

LEVEL CALIBRATION CHECK (X-AXIS)

1. Set up a tripod between two walls that are at least 15 m (50 feet) 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 5.
5. Turn the entire laser unit 180° so the X-axis points directly toward the opposite wall.
6. Allow the laser unit to self-level, and mark and measure points AA and BB on the walls as shown in Figure 6.
7. Calculate the total error using the equation:
8. Compare total error to the allowable limits shown in the following table.

$$ \text { Total Error } = (A A - A) - (B B - B) $$

Distance between walls	Allowable Error
L = 15 m (50 ft.)	3 mm (0.125")
L = 25 m (80 ft.)	5 mm (0.2")
L = 50 m (160 ft.)	10 mm (0.4")

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.

Cleaning

WARNING:

• Unplug the charger before cleaning. Dirt and grease may be removed from the exterior of the charger using a cloth or soft non-metallic brush. Do not use water or any cleaning solutions.
• Remove the battery pack before cleaning your laser unit.
• Never use solvents or other harsh chemicals for cleaning the non-metallic parts of the laser. 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.

ENGLISH

• Never use compressed air to clean the laser.
• Keep the ventilation slots clear and regularly clean the housing with a soft cloth.
• 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.
• 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.

Rechargeable Battery Pack

This long life battery pack must be recharged when it fails to produce sufficient power on jobs which were easily done before. At the end of its technical life, discard it with due care for our environment:

• Run the battery pack down completely, then remove it from the tool.
• Li-Ion, NiCd and NiMH cells are recyclable. Take them to your dealer or a local recycling station. The collected battery packs will be recycled or disposed of properly.

Protecting the Environment

Separate collection. This product must not be disposed of with normal household waste.

Should you find one day that your DEWALT product needs replacement, or if it is of no further use to you, do not dispose of it with household waste. Make this product available for separate collection.

Separate collection of used products and packaging allows materials to be recycled and used again. Re-use of recycled materials helps prevent environmental pollution and reduces the demand for raw materials.

Local regulations may provide for separate collection of electrical products from the household, at municipal waste sites or by the retailer when you purchase a new product.

DEWALT provides a facility for the collection and recycling of DEWALT products once they have reached the end of their working life. To take advantage of this service please return your product to any authorised repair agent who will collect them on our behalf.

You can check the location of your nearest authorised repair agent by contacting your local DEWALT office at the address indicated in this manual. Alternatively, a list of authorised DEWALT repair agents and full details of our after-sales service and contacts are available on the Internet at:
