DeWalt DW076 Instructions Manual page 33

Instructions for use
Always observe the safety instructions
and applicable regulations.
• Always mark the center of the laser line or dot.
• To increase working distance and accuracy, set
up the tool in the middle of your working area.
• Extreme temperature changes cause movement
of internal parts that may affect the accuracy of
the tool. Regularly check the accuracy while
using the tool under these circumstances.
• Although the tool corrects small out-of-level errors
automatically, when it has registered a bump,
re-adjustment to balance or set-up may be
required.
• If the tool has been dropped or has tipped over,
have the laser head calibrated by a qualified
repair agent.
Prior to operation:
• Carry out the field calibration checks to confirm
its accuracy.
• Make sure the tool has been set up securely.
Switching on and off (fig. A)
• To switch the tool on, press the on/off switch (1).
• To switch the tool off, press the on/off switch (1)
again.
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
automatically corrected without notifying.
– Deviations 2 - 20 mm over 10 m: a level error is
automatically 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 set-
up and re-adjust if required before switching
the tool on again.
Digital laser detector (fig. F)
The detector helps locating the position of a laser
beam in bright light conditions or over long distances.
It produces both visual and audio signals as the
rotating laser beam crosses the detector.
The attachment can be used both indoor and outdoor
whenever it is difficult to locate the laser beam.
Accuracy
When the tool is operated using the detector,
the accuracy level of the detector needs to be
added to that of the tool.
– Constant accuracy (detector in narrow setting)
+/- 1.0 mm/m
– Nominal accuracy (detector in wide setting)
+/- 3.0 mm/m
• For most accurate results, start the operation
using the wide setting and finish in the narrow
setting.
