Rotating the laser head (fig. G1 & G2)
In the stationary position, the laser head can be moved
both to the left and to the right.
Level applications:
• Use the keys (20) to move the laser head into the re-
quired direction.
Plumb applications:
• Use the keys (21) to move the laser head into the re-
quired direction.
Manually rotating the laser head (fig. G2)
The laser head can also be rotated manually.
• Turn the laser head (10) into the required position.
Do not attempt to move the laser head while it is
rotating at a preset rotation speed.
Scan mode (fig. H)
The laser head can be set to different speed settings
while moving back and forth, thus projecting a scanning
laser line.
• Press the key (18) to activate the scan mode.
The scan speed starts at “fast” rate.
• To set the scan speed press the key (19). The scan
speed will cycle from “crawling” to “slow”, “medium” and
“fast” each time the key is pressed.
• Level applications:
- Use the keys (20) to move the scan area into the re-
quired direction.
- Use the keys (21) to adjust the scan area.
• Plumb applications:
- Use the keys (21) to move the scan area into the re-
quired direction.
• Press the key (18) to discontinue the scan mode.
Out-of-level alert
The out-of-level alert activates automatically 8 seconds
after the leveling procedure has been completed. Once
the out-of-level alert is activated, the tool monitors its
level position continuously. Depending on the registered
level of deviation the tool will respond to level errors as
follows:
- Deviations < 2 mm over 10 m: a level error is automati-
cally corrected without notifying.
- Deviations 2 - 20 mm over 10 m: a level error is auto-
matically corrected. The laser head temporarily stops
rotating and the laser beam starts flashing to indicate that
the tool re-adjusts to level position.
- Deviations > 20 mm over 10 m: a level error leads to
interruption of the tool’s operation. The laser head stops
rotating and the laser beam goes off. A rapidly beeping
audio signal is produced and the on/off indicator flashes
simultaneously. To resume the operation:
• Switch the tool off. Check the balance and setup and re-
adjust if required before switching the tool on again.
Tool aids (fig. I1 - I4)
Several aids have been supplied that might be
helpful while operating the tool.
Remote control (fig. I1)
The remote control allows a manual intervention of the
self-leveling feature when slope adjustment is required.
The maximum slope angle corresponds to the self-lev-
eling range of the tool. The remote control also allows
you to activate the laser line and control the laser head
from distances up to 30 m radius.
Laser enhancement glasses (fig. I2)
The red lens glasses improve the visibility of the laser
beam under bright light conditions or over long distances.
Providing best results indoors, the lens filters out ambient
light and intensifies the projected dot or line. The glasses
do not keep the laser beam from entering the eyes.
Never look into the laser beam directly
with these glasses.
DE0730 Target card (fig. I3)
The target card locates and marks the laser beam as the
beam crosses the card, thus enhancing the visibility of
the projected line. The laser beam passes through the
red plastic surface and is reflected by the reflective rear
side of the card. Supporting easy use during plumb and
level adjustment, the card is marked with inch and metric
scales, and has magnets at the top to hold it to ceiling
track or steel studs.
Wall mount (fig. I4)
The wall mount may also be used as a base to provide
extra stability for the tool.

Maintenance
Your DEWALT Power Tool has been designed to operate
over a long period of time with a minimum of mainte-
nance. Continuous satisfactory operation depends upon
proper tool care and regular cleaning.
Field calibration check
The field calibration checks must be performed securely
and accurately to make a correct diagnosis.
Whenever an error is registered, have the tool calibrated
by a qualified repair agent. Always have the laser head
calibrated by a qualified repair agent.
Level checks
The following checks are performed to check the calibra-
tion of laser head for level alignment.
• Place the tool in an area at about 15 m from a vertical
surface.
• With the tool in a tripod set-up, adjust the tool for a level
application.
To perform a level check of the X-axis:
