remain between 20%–85%.
•
Adjustment, maintenance, and repair of the electrical components of this engraver must be done
ONLY by trained and skilled professionals to avoid fires and other malfunctions, including potential
radiation exposure from damage to the laser components. Because specialized techniques are
required for testing the electrical components of this marking system, it is recommended such
testing only be done by the manufacturer, seller, or repair service.
•
Unless otherwise specified, ONLY undertake adjustment, maintenance, and repair of the engraver
when it is turned off, disconnected from its power supply, and fully cooled.
1.6 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 engraver 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 injury 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. Always wear hand
protection when working with metal to avoid cuts and burns.
•
DO NOT ever under ANY circumstances use this laser engraver if the exhaust system is not
working properly. Always ensure that the exhaust fan 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 fan or vent hose malfunctions. Periodically check the air
assist intake filter to ensure it stays free of any dust or debris.
•
Exercise special caution when working with moderately conductive materials such as carbon
steel and stainless steel, as prolonged work can build up residual heat and reflective dust and
particles that may damage electrical components, cause short circuits, or produce other effects
including reflected laser radiation.
•
DO NOT use standard surge protectors, extension cords, or power strips. Only use additional
wiring thick enough to safely handle the full load of the machine.Use only surge protectors rated
over 2000 J.
•
ONLY turn on the power to this engraver when it is well grounded, either via a firm connection to a
3-prong outlet or via a dedicated grounding cable firmly connected to the grounding port on the
engraver. Do not use an ungrounded 3-to-2 prong adapter. The engraver’s grounding should be
checked regularly for any damage to the line or loose connections.
