SAVE ALL WARNINGS AND INSTRUCTIONS FOR
FUTURE REFERENCE
The term “tool” in the warnings listed below refers to your mains-
operated (corded) tool or battery-operated (cordless) tool.
The following labels are
on your laser tool for
your convenience and
safety. They indicate where
the laser light is emitted by the tool. ALWAYS BE AWARE of their
location when using the tool.
Do not direct the laser beam at persons or animals
and do not stare into the laser beam yourself. This tool
produces laser class 2 laser radiation and complies
with 21 CFR 1040.10 and 1040.11 except for deviations
pursuant to Laser Notice No. 50, dated June 24, 2007. This can
lead to persons being blinded.
Changes or modifications to this equipment not expressly
approved by the party responsible for compliance could void the
