2.3 Laser Safety Instructions

This machine uses an invisible CLASS 4 LASER, the strongest and most dangerous class of
laser available for public use. Used without care, it can 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.
• DO NOT use or leave sensitive EMI equipment nearby. Ensure the area around the laser is
free of strong electromagnetic interference during any use.
• ONLY use this machine as described in the Material Safety section of this manual. The laser
settings and engraving process must be properly adjusted for specific materials.
• Ensure the area is kept free of airborne pollutants, as these might pose a similar risk of
