Important Safety Instructions
for Batteries
WARNING: Batteries can explode, or leak, and can cause
injury or fire. To reduce this risk:
• Carefully follow all instructions and warnings on the battery label
and package.
• Always insert batteries correctly with regard to polarity (+ and –),
marked on the battery and the equipment.
• Do not short battery terminals.
• Do not charge batteries.
• Do not mix old and new batteries. Replace all of them at the
same time with new batteries of the same brand and type.
• Remove dead batteries immediately and dispose of per local
codes.
• Do not dispose of batteries in fire.
• Keep batteries out of reach of children.
• Remove batteries if the device will not be used for several
months.

FOR FUTURE USE
LASER OPERATION
• To extend battery life, turn the laser off when it is not in use.
• To ensure the accuracy of your work, check the laser
calibration often. Refer to Field Calibration 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
effect accuracy. Check your accuracy often while working.
