Call 2 Recycle, Inc., in cooperation with DeWALT and other battery users,
has established the program in the United States and Canada to facilitate the
collection of spent nickel cadmium, nickel metal hydride or lithium-ion batteries.
Help protect our environment and conserve natural resources by returning
the spent nickel cadmium, nickel metal hydride or lithium-ion batteries to an
authorized
DeWALT service center or to your local retailer for recycling. You may
also contact your local recycling center for information on where to drop off the
spent battery. RBRC® is a registered trademark of Call 2 Recycle, Inc.
Operating Tips
• To extend battery life per charge, turn the laser off when it is not
in use.
• To ensure the accuracy of your work, check the laser calibration
often. Refer to Checking the Calibration.
• Before attempting to use the laser, make sure the tool is
positioned on a relatively smooth, secure surface.
• Always mark the center of the laser line or dot. If you mark
different parts of the beam at different times you will introduce
error into your measurements.
• To increase working distance and accuracy, set up the laser in the
middle of your working area.
• When attaching to a tripod or wall, mount the laser securely.
• When working indoors, a slow rotary head speed will produce
a visibly brighter line, a faster rotary head speed will produce a
visibly solid line.
• To increase beam visibility, wear Laser Enhancement Glass es
(Figure
T
) and/or use a Laser Target Card (Figure
S
) to help find
the beam.
• Extreme temperature changes can cause movement or shifting
of building structures, metal tripods, equipment, etc., which can
effect accuracy. Check your accuracy often while working.
• If the laser is dropped or has suffered a sharp blow, have the
calibration system checked by a qualified service center before
using the laser.
Turning the Laser On
1.
Insert the fully charged DEWALT 20V battery pack as shown in
Figure
D
.
2.
Gently press the power button to power ON the laser:
• The power LED indicator light (Figure
A
3
) will illuminate.
• Self-leveling mode is activated automatically and the laser unit
will self-level. Once the laser unit is level, the beam will rotate
clockwise once at 600RPM.
• 30 sec. after the last button press, HI Mode (Height of
Instument, Anti-Drift) is activated automatically and the HI LED
(Figure
A
2
) will illuminate. (You can disable HI Mode by
holding down the Slope Mode button for 2 secs. The laser
will beep twice and the HI Mode LED will turn off. NOTE: when
HI Mode is disabled, the laser cannot detect any movement
after setup, so accuracy cannot be guaranteed.)
3.
Press (Figure
A
16
) to adjust the Rotation Speed of the
laser beam through its 4 preset speeds (150, 300, 600, and
1200 RPM). NOTE: Accuracy is best optimized at 600 RPM or
less.
4.
To change the Direction of the laser beam while in self-leveling
mode, press or (Figure
A
18
or
19
).
5.
Press the Scan Mode button
15˚/45˚/90˚
(Figure
A
17
) to set the laser
to scan in 0°, 15°, 45°, or 90° angle mode.
•
15˚/45˚/90˚
is used to make the laser head sweep back and forth,
creating a short, bright laser line. This short line is much
brighter and more visible than when the unit is in full rotation
mode.
• The direction of the scan zone can be controlled with the arrow
buttons
and (Figure
A
18
or
19
)
6.
If you press the Slope Mode button to turn ON Slope Mode,
the unit automatically engages the X-Axis. This allows you to
slope the laser in the direction of the X-Axis, as indicated by the
X mark on the top roll cage.
• In certain situations, it may be desirable to slope the laser in
the Y-axis. The direction of Slope Mode can be changed back
and forth between the Y-axis and the X-axis by pressing the
X-Y axis button
(Figure
A
13
).
