Maintenance
Laser Cleaning and Storage
• Under some conditions, the glass lens 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.
• 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 Checking the Calibration.
• Calibration checks and other maintenance repairs can be
performed by D
EWALT service centers. Two free calibration checks
are included under the DEWALT One Year Free Service Con tract.
• When the laser is not in use, store it in the kit box provided.
• 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.
Detector Cleaning and Storage
• Dirt and grease may be removed from the exterior of the detector
using a cloth or a soft, non-metallic brush.
• The D
EWALT Digital Laser Detector is waterproof. If you should
drop the detector in mud, wet concrete, or a similar substance,
simply hose the detector off. Do not use high pressure water (e.g.,
from a pressure washer).
• The best storage place is one that is cool and dry, and away from
direct sunlight and excess heat or cold.

) to turn the detector on.
4.
If the detector still does not turn on, take the detector to a
DEWALT service center.

laser beam.
4.
If the detector is still not making any sound, take it to a DEWALT
service center.
