• The D WALT Digital Laser Detector is waterproof. If you
e
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–away from
direct sunlight and excess heat or cold.
Detector Service
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
D WALT service center.
e
The detector's speaker makes no sound.
• Ensure that the detector is on.
• Press the volume button. It will toggle on and off.
• Ensure that the laser is turned on and that it is emitting a
laser beam.
• If the detector is still not making any sound, take it to a
D WALT service center.
e
The detector does not respond to the
beam from another laser unit.
• The D WALT Digital Laser Detector has been designed to
e
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 D WALT service center.

Construction Grade Rod (Fig. L)

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 D
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
34
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 L.

Field Calibration Check (Fig. O, P)
Field calibration checks should be done frequently. This section
provides instructions for performing simple field calibration
checks of your D
not calibrate the laser. That is, these checks do not correct errors
in the leveling or plumbing capability of the laser. Instead, the
WALT Grade Rod
e
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 D
Level Calibration Check (X-axis)
MAINTENANCE

e
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 Field Calibration Check.
Calibration checks and other maintenance repairs can be
performed by D WALT service centers. Two free calibration
e
checks are included under the D
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 -18˚C or
above 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.
WALT Rotary Laser. Field calibration checks do
e
1. Set up a tripod between two walls that are at least 15 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.
