2.4 Electrical Safety Instructions
• ONLY use this device with a compatible and stable power supply with less than 5% fluctuation in its voltage.
• DO NOT connect other devices to the same fuse, as the laser system will require its full amperage. Do not use
with standard extension cords or power strips. Use only surge protectors rated over 2000J.
• ONLY turn on the power to this device 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 proper slot on the
cabinet. Do not use with an ungrounded 3 to 2 prong adapter. The device's grounding should be
checked regularly for any damage to the line or loose connections.
• The area around this laser engraving device should be kept dry, well ventilated, and environmentally
controlled to keep the ambient temperature between 40–95°F (5–35°C). For best results, keep
the temperature at 75°F (25°C) or below. The ambient humidity should not exceed 70%.
• Adjustment, maintenance, and repair of the electrical components of this device 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 device when it is turned
off, disconnected from its power supply, and fully cooled.
2.5 Material Safety Instructions
• Users of this laser engraving machine are responsible for confirming that 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 the 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.
• 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.
• Users must exercise special caution when working with conductive materials as buildup of their dust and ambient
particles may damage electrical components, cause short circuits, or produce other effects including reflected
laser radiation.
