Use of controls or adjustments or
performance of procedures other than
those specified in this manual, may result
in hazardous radiation exposure.
ALWAYS make sure that any bystanders
in the vicinity of use are made aware of the
dangers of looking directly into the laser
tool.
DO NOT place the laser tool in a position
that may cause anyone to stare into the
laser beam intentionally or unintentionally.
Serious eye injury could result.
ALWAYS position the laser tool securely.
Damage to the laser tool and/or serious injury
to the user could result if the laser tool fails.
ALWAYS use only the accessories that are
recommended by the manufacturer of your
laser tool. Use of accessories that have been
designed for use with other laser tools could

DO NOT use this laser tool for any purpose
other than those outlined in this manual.
This could result in serious injury.
DO NOT leave the laser tool "ON"
unattended in any operating mode.
DO NOT disassemble the laser tool. There
are no user serviceable parts inside. Do not
modify the product in any way. Modifying
the laser tool may result in hazardous laser
radiation exposure.
DO NOT use the laser viewing glasses as
safety goggles. The laser viewing glasses
are used for improved visualization of the laser
beam, but they do not protect against laser
radiation.
DO NOT use the laser viewing glasses as
sun glasses or in traffic. The laser viewing
glasses do not afford complete UV protection
and reduce color perception.
DO NOT use any optical tools such as, but
not limited to, telescopes or transits to view
the laser beam. Serious eye injury could result.
DO NOT stare directly at the laser beam or
project the laser beam directly into the eyes
of others. Serious eye injury could result.
Work area safety
Keep work area clean and well lit. Cluttered
or dark areas invite accidents.
DO NOT operate the laser tool around
children or allow children to operate the
laser tool. Serious eye injury could result.
DO NOT use laser tools, attachments and

accessories outdoors when lightning
conditions are present.
Do not operate the laser tool in explosive en-
vironments, such as in the presence of flam-
mable liquids, gases or dusts. Sparks can be
created in the laser tool which may ignite the
dust or fumes.
Electrical safety
To reduce this risk, always follow all instructions
and warnings on the battery label and package.
DO NOT expose the laser tool and battery to
rain or wet conditions. Water entering laser
tool will increase the risk of fire and personal
injury.
DO NOT short any battery terminals.

Personal safety
If laser radiation strikes your eye, you must
deliberately close your eyes and immediate-
ly turn your head away from the beam.
Do not make any modifications to the laser
equipment.
Stay alert, watch what you are doing and
use common sense when operating a tool.
Do not use a tool while you are tired or
under the influence of drugs, alcohol or
medication. A moment of inattention while
operating a tool may result in serious personal
injury or incorrect measurement results.
Use safety equipment. Always wear
eye protection. Safety equipment such as
dust mask, non-skid safety shoes, hard hat,
or hearing protection used for appropriate
conditions will reduce personal injuries.
Use caution when using laser tools in the
vicinity of electrical hazards.
