Safety Information
Your safety is paramount when operating laser equipment. The ORTUR Laser Master 2 S2 LU2-2 incorporates several safety features, but it is crucial to understand and follow all safety guidelines.
- G-sensor Protection: The motherboard is equipped with a G-sensor. If the engraving machine is displaced or tilted during operation, the laser will automatically stop to prevent accidents.
- USB Disconnection Safety: In the event of a computer system halt or USB cable disconnection, which causes the laser engraver to stop moving, the laser beam will automatically cease operation to prevent fire hazards.
- Idle Shutdown: If the engraving machine is turned on but remains stationary for an extended period, the laser will automatically turn off.
- Eye Protection: The laser engraver features a panoramic filter glass protective cover. This cover is designed to filter 97% of ultraviolet light, providing significant eye protection and reducing the need for additional goggles. However, always exercise caution and consider wearing appropriate laser safety glasses.
Always operate the laser engraver in a well-ventilated area and ensure no flammable materials are near the working surface. Never leave the machine unattended during operation.
