DeWalt DW074 Instructions Manual page 31

OPERATION
WARNING: Always observe the safety
instructions and applicable regulations.
• To extend battery life, remove batteries when
the laser is not in use.
• To ensure the accuracy of your work, check
the laser calibration often. Refer to Field
Callibration Check under Laser Maintenance.
• 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 and/or use a Laser
Target Card to help find the beam.
• Extreme temperature changes can cause
movement or shifting of building structures,
metal tripods, equipment, etc., which can affect
accuracy. Check your accuracy often while
working.
• When working with the D
Detector, set the laser's rotation speed to the
fastest setting.
• If the laser is dropped or suffers a sharp blow,
have the calibration system checked by a
qualified service centre before using the laser.
