- Ensure reliable grounding before operating the laser.
- Verify that the laser system and the output head are placed on a horizontal and stable operating platform. If the laser is installed on a metal platform, ensure good electrical contact between the laser unit and the mounting platform, and make sure the system is properly grounded.
- Ensure that all laser components are securely fixed to prevent them from falling, experiencing strong vibration, or causing damage to the laser system.
- The minimum bending radius of the laser output armored cable shall not be less than 20 cm during transportation, storage, or operation.
- Before installation, confirm that the external AC power switch and the leakage circuit breaker on the rear panel of the laser are turned off. Also ensure that the emergency stop switch, push-button switch, and key switch on the front panel are in the OFF position.
- Do not install or remove the laser output head while the laser is operating.
- Do not look directly into the laser output head. Always wear appropriate laser safety protective eyewear when operating the laser.
- Do not expose the product to environments with high humidity (humidity > 95%).
- Do not operate this product when the ambient temperature is below the dew point temperature.
