Laser Enhancement Glasses (Fig. F)
Some laser kits include a pair of Laser En hancement Glasses.
These glasses improve the visibility of the laser beam under
bright light conditions or over long distances when the laser is
used for interior applications. These glasses are not required to
operate the laser.

CAUTION: These glasses are not ANSI approved safety
glasses and should not be worn while operating other
tools. These glasses do not keep the laser beam from
entering your eyes.

DANGER: To reduce the risk of serious personal injury,
never stare directly into the laser beam, with or without
these glasses.
Target Card (Fig. G)
Some laser kits include a Laser Target Card to aid in locating
and marking the laser beam. The target card enhances the
visibility of the laser beam as the beam crosses over the card.
The card is marked with standard and metric scales. The laser
beam passes through the red plastic and reflects off of the
reflective tape on the reverse side. The magnet at the top of
the card is designed to hold the target card to ceiling track or
steel studs to determine plumb and level positions. For best
performance when using the Target Card, the D
should be facing you.
Digital Laser Detector: DW0743R (red beam)
& DW0743G (green beam) (Fig. H–K)
Some laser kits include a D
D
WALT Digital Laser Detector allows you to locate a laser
e
beam emitted by a rotary laser in bright light conditions or over
long distances. The detector can be used in both indoor and
outdoor situations where it is difficult to see the laser beam.
The detector is not for use with non-rotating lasers but is
compatible with most rotary red-beam (DW0743R) and green
beam (DW0743G) lasers. It can be set to indicate the location of
the beam to either the nearest 1/8" (3 mm) or the nearest 1/25"
(1 mm). The detector gives both visual signals through the
display window
and audio signals through the speaker
 22 
to indicate the location of the laser beam.
The D
WALT Digital Laser Detector can be used with or without
e
the detector clamp. When used with the clamp, the detector
can be positioned on a grade rod, leveling pole, stud or post.
Batteries (Fig. H)
The Digital Laser Detector is powered by a 9 volt battery. To
install the battery provided, lift up on the battery compartment
cover
 21 
. Place the 9 volt battery in the compartment, aligning
the battery as shown .
Detector Controls (Fig. I)
The detector is controlled by the power button

WALT Digital Laser Detector also has an auto shut-off feature.
e
If a rotary laser beam does not strike the beam detection
window, or if no buttons are pressed, the detector will shut
itself off in about 30 minutes.
When the detector is on, the top of the window shows an
accuracy mode icon. Either the ±1/25" (1 mm) accuracy mode
icon
will appear, or the ±1/8" (3 mm) accuracy mode icon
 53 
will appear. When the ±1/25" (1 mm) accuracy mode icon
 54 
appears, it indicates that the detector will give an "on grade"
reading only when the laser beam is on grade or no more
than 1/25" (1 mm) above or below it. When the 1/8" (3 mm)
accuracy mode icon appears, it indicates that the detector will
give an "on grade" reading when the laser beam is on grade
or approximately 1/8" (3 mm) above or below it. Push the
accuracy mode button
Detector Operation (Fig. I, J)
1. Set up and position the rotary laser that you will be using
according to the manufacturer's directions. Turn the laser
on and make sure that the laser is rotating and emitting a
laser beam. NOTE: This detector has been designed to be
used only with a rotating laser. The detector will not work
with a stationary beam laser level.
2. Turn the detector on by pressing the power/volume
button 
3. Adjust the volume as desired as described in the
Detector Controls.
4. Position the detector so that the detector window
facing the laser beam produced by the rotary laser. Move
the detector up or down within the approximate area of the
beam, until you have centered the detector. For information
about the display window indicators and the audible signal
indicators, refer to the table titled Indicators (Fig. J).
5. Use the marking notches
position of the laser beam.
Mounting on A Grade Rod (Fig.K)
 23 
To secure your detector to a grade rod, first attach the detector
to the clamp using the 1/4"-20 threaded knob
of the clamp. Slide the tracks
on the grade rod.
 33 
1. Position the detector at the height needed and turn the
clamp knob clockwise to tighten the jaws of the clamp
around the grade securing the clamp on the rod.
2. To make adjustments in height, slightly loosen the clamp,
reposition and retighten.
Detector Cleaning and Storage
Dirt and grease may be removed from the exterior of the
and the
detector using a cloth or soft, non-metallic brush.
The D
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.
