Bosch GLM 50 C Operating/Safety Instructions Manual page 9

Never aim the beam at a workpiece with a reflective
surface. Bright shiny reflective sheet steel or similar
reflective surfaces are not recommended for laser
use. Reflective surfaces could direct the beam back
towards the operator.
Use of controls or adjustments or performance of
procedures other than those specified herein may
result in hazardous radiation exposure.
DO NOT use any optical tools such as, but not limited
to, telescopes or transits to view the laser beam. Se-
rious eye injury could result.
DO NOT leave the laser measure "ON" unattended in
any operation mode. ALWAYS turn the laser measure
"OFF" when not in use. Leaving the laser measure
"ON" increases the risk of someone inadvertently star-
ing into the laser beam.
DO NOT operate the laser measure in combustible
areas such as in the presence of flammable liquids,
gases or dust.
Do not use the laser viewing glasses as safety gog-
gles. 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.
ALWAYS position the laser measure securely. Dam-
age to the laser measure and/or serious injury to the
user could result if the laser measure falls.
Take care to recognize the accuracy and range of the
laser measure. Measurement may not be accurate if
used beyond the rated range of the laser measure.
DO NOT remove or deface any warning or caution
labels. Removing labels increases the risk of exposure
to laser radiation.
