2. Safety Guidelines
Operating a laser engraver requires adherence to strict safety protocols. Failure to follow these guidelines can result in serious injury or damage to the equipment.
- Eye Protection: Never look directly into the laser beam. The machine features a widened viewing window made from flame-retardant material for safe observation.
- Ventilation: Ensure adequate ventilation to remove smoke and fumes generated during operation. The integrated air assist system helps keep the work area clear.
- Automatic Cover Interlock: The laser automatically shuts off when the lid is opened, preventing accidental exposure to the laser beam.
- Material Compatibility: Only engrave or cut materials approved for CO2 lasers. Refer to the material compatibility chart in Section 5.
- Emergency Stop: Familiarize yourself with the location and operation of the emergency stop button.

3. Setup
Proper setup is crucial for optimal performance and safety.
3.1. Placement
Place the machine on a stable, level surface in a well-ventilated area. Ensure sufficient space around the machine for operation and maintenance, especially considering the 4-way pass-through feature.
3.2. Connections
- Power: Connect the machine to a grounded power outlet.
- Water Pump/Cooling System: Connect the external water pump to the machine and ensure it is filled with distilled water. This system is vital for cooling the laser tube during operation.
