• Ventilación: Ensure adequate ventilation to remove smoke and fumes generated during operation. The integrated exhaust fan assists in this process.
• Seguridad contra incendios: Keep a fire extinguisher nearby. Do not leave the machine unattended during operation. The flame-retardant acrylic panel offers some protection.
• Protección del agua: Ensure the water cooling system is properly connected and functioning to prevent the laser from firing without adequate cooling.
• Parada de emergencia: Familiarize yourself with the emergency stop button and its location for immediate shutdown in critical situations.
• Door and Water Protection: The machine includes safety interlocks that prevent laser operation if the lid or water cooling is not correctly engaged.

3. Configuración

3.1 Desempaquetado y colocación

Carefully remove the laser engraver from its packaging. Place the machine on a stable, level surface in a well-ventilated area. Ensure sufficient space around the machine for air circulation and access.

3.2 Sistema de refrigeración por agua

The K40+ features a built-in water cooling tube. Connect the external water pump (if supplied) to the designated inlet and outlet ports on the machine. Fill the water reservoir with distilled water. Ensure water flows correctly through the system before powering on the laser. Incorrect hose connection can prevent operation.

3.3 Sistema de asistencia de aire

The integrated 45° air assist system automatically adjusts airflow based on laser power. This system helps clear smoke and debris from the cutting area, protects the lens, reduces wood carbonization, and minimizes fire risk. Ensure the air assist nozzle is clear of obstructions.

4. Instrucciones de funcionamiento

4.1 Encendido y comprobaciones iniciales

After ensuring all connections are secure and safety measures are in place, power on the machine. Verify that the water protection system is active and the lid is closed. The digital ammeter displays the current output to the laser tube.

4.2 Material Placement and Focusing

Place your material on the honeycomb workbed. The work area is 12"x8" (300mm x 200mm). The laser head is adjustable, allowing for effortless engraving on various material thicknesses. Adjust the laser head's length to achieve the correct focal point for your material.
