2. Safety Information

Operating a Class 4 laser device requires strict adherence to safety protocols. Failure to follow these guidelines can result in serious injury or damage to property.

2.1 General Safety Precautions

• Always wear appropriate laser safety goggles during operation. The laser emits invisible radiation that can cause permanent eye damage.
• Ensure the work area is well-ventilated to dissipate fumes and smoke produced during engraving or cutting.
• Never leave the machine unattended while it is operating.
• Keep a fire extinguisher nearby. Certain materials can ignite during laser processing.
• Keep children and pets away from the operating area.
• Do not engrave or cut reflective materials without proper precautions, as reflected laser beams can be hazardous.
• Ensure the emergency stop switch is easily accessible and understood by all users.

2.2 Integrated Safety Systems

The ORTUR Laser Master 3 is equipped with 7 safety protection systems:

1. Safety Lock: Requires a key for professional use, preventing unauthorized operation.
2. Active Position Protection: Stops operation if the machine is moved or tilted unexpectedly.
3. Sloping Position Protection: Detects and halts operation if the machine's angle changes significantly.
4. Exposure Duration Detection and Limitation: Prevents prolonged laser exposure in one spot.
5. Voltage and Current Safety Control System: Monitors electrical parameters for safe operation.
6. Host Computer Watchdog: Ensures continuous communication and control from the host device.
7. Emergency Stop Switch: Immediately cuts power to the laser in case of an emergency.
