Part 2: User Security Statement
Laser light can harm human eyes and skin. Do not expose eyes or skin directly to the laser light. This product emits a collimated laser beam through an optical lens. The emitted light, direct or reflected, can be very harmful and travel long distances while maintaining high optical density. When handling the product, wear appropriate goggles (OD5+) to protect eyes from all laser light, including reflected and stray light. Reflected and stray light should be attenuated and/or absorbed.
2.1 Laser Safety
A laser shield is installed to filter most diffuse reflection. However, it is recommended to wear laser protective glasses to prevent eye damage. Avoid skin exposure to Type 4 laser beams, especially at close distances. Teenagers must be supervised by parents. Do not touch the laser engraving module while the machine is active.
2.2 Fire Safety
Cutting burns the substrate, generating high temperatures and heat. Certain materials can catch fire, producing gases and fumes. A small flame may appear when the laser beam hits the material. This flame moves with the laser and extinguishes when the laser passes. Do not leave the machine unattended during the engraving process. After use, clean up debris and flammable materials. Always keep a fire extinguisher nearby. Laser engraving machines produce smoke, vapor, particles, and potentially toxic fumes/air pollutants from materials, which can be hazardous to health.
2.3 Material Safety
Do not engrave materials with unknown properties. Recommended materials: wood, bamboo, leather, plastic, fabric, paper, opaque acrylic glass. Materials not recommended: gold, silver, copper, aluminum, transparent and translucent acrylic, precious stones, reflective materials. If reflective materials need engraving, use a paint pen to draw black on them to avoid reflection.
2.4 Use Safety
Use the engraver only in a horizontal position and ensure it is securely fixed to prevent fires from accidental shifting or dropping. Do not point the laser at people, animals, or any combustible object, whether the machine is working or not.
2.5 Power Safety
To prevent fire and electric shock, the engraver includes a power adapter with a ground wire. Plug the power cord into a power socket with a ground wire.
2.6 Environment Safety
When installing engraving and cutting equipment, ensure the workplace is clean and free of flammable or explosive materials. Place a metal plate under the equipment when engraving or cutting.
