1.7 Material Safety Instructions
• Users of this laser engraving machine are responsible for confirming that the materials
to be processed can withstand the heat of the laser and will not produce any emissions
or byproducts either harmful to people nearby or in violation of local or national laws or
regulations. In particular, DO NOT use this device to process polyvinyl chloride (PVC),
Teflon, or other halogen-containing materials under ANY circumstances.
• Users of this laser engraver are responsible for ensuring that every person present
during operation has sufficient PPE to avoid injuries from the emissions and byproducts
of the materials being processed. In addition to the protective laser eyewear described
above, this may require goggles, masks or respirators, gloves, and other protective outer
clothing.
• DO NOT ever under any circumstances use this laser engraver if the exhaust system is
not working properly. ALWAYS ensure that the exhaust fans can remove the dust and
gas produced by the engraving process in accordance with ALL applicable local and
national laws and regulations. Immediately stop use if the exhaust fans or vent pipes
malfunction. Periodically check the air assist intake filter to ensure it stays free of any
dust or debris.
• Exercise special caution when working with conductive materials as the buildup of their
dust and ambient particles may damage electrical components, cause short circuits, or
produce other effects including reflected laser radiation.
