Laser Safety Instructions - Omtech LYF-175S User Manual

• DO NOT allow minors, untrained personnel, or personnel suffering from physical or mental
impairment that would affect their ability to follow this manual and the software manual to
install, operate, maintain, or repair this device.
• Any untrained personnel who might be near the device while it is in operation MUST be
informed that it is dangerous and fully instructed on how to avoid injury during its use.
• Always keep a fire extinguisher, water hose, or other flame-retardant system nearby in case of
accidents. Ensure that the local fire department's phone number is clearly displayed nearby. In
the case of a fire, cut electrical power before dousing the flame. Familiarize yourself with the
correct range for your extinguisher before use. Take care not to use your extinguisher too close
to the flame, as its high pressure can produce blowback.

1.4 Laser Safety Instructions

This machine complies with 21 CFR 1040.10 and 1040.11 except for conformance with IEC 60825-1
Ed. 3., as described in Laser Notice No. 56, dated May 8, 2019.
When used in accordance with these instructions, it is a CLASS 4 laser product. Use of controls
or adjustments or performance of procedures other than those specified herein may result in
hazardous radiation exposure. Used without care, it can also cause serious property damage and
personal injury including but not limited to the following:
• The laser will easily burn nearby combustible materials
• Some working materials may produce radiation or harmful gasses during processing
• Direct exposure to the laser will cause bodily harm including serious burns and
irreparable eye damage
As such,
• NEVER interfere with the laser beam.
• DO NOT place any part of your body under the laser lens during operation. Take measures to
protect yourself from potentially reflected laser beams including the use of screens or personal
protective equipment.
• NEVER attempt to view the laser directly without protective eyewear. Always wear safety
goggles or glasses designed to filter the specific wavelength of your engraver's laser with an
optical density (OD) of 5+. As even seemingly matte materials can produce harmful reflected
beams, care should be taken to keep anyone without protective eyewear from observing the
machine during operation. EVEN WITH protective eyewear, do not stare or allow others to stare
continuously at the laser beam during operation.
• DO NOT leave potentially combustible, flammable, explosive, or corrosive materials nearby
where they could be exposed to the direct or reflected laser beam.
