2. Safety Information
Please read and understand all safety warnings before operating the device.
2.1 Warnings & Safety Information
- Fire and Burn Hazard: High temperatures generated during processing may ignite the workpiece, smoke, or surrounding materials. The processing area must be kept clear of flammable substances and equipped with fire extinguishing equipment. After processing, the workpiece and machine components (e.g., spindle, laser head) may remain hot for an extended period; verify full cooling before handling.
- Mechanical Injury Hazard: High-speed rotating spindles, moving gantries, belts, and lead screws pose serious risks of crushing, cutting, or entanglement injuries. Before performing any installation, commissioning, cleaning, or maintenance operation, disconnect the machine from the main power supply.
- Electrical Hazard: High-voltage circuits are present internally. Unauthorized personnel must not open the electrical control cabinet. All electrical connections must comply with local regulations and be performed by qualified electricians.
- Hazardous Substances and Fumes: Processing certain materials (e.g., plastics, composites, coated metals) may generate toxic, carcinogenic, or irritating fumes and dust. Use only in environments equipped with an effective Local Exhaust Ventilation (LEV) system.
