Maintenance / cleaning
Always disconnect from mains before cleaning/opening the laser. Regularly clean the
interior from dust, especially ensure operation of the fans. Use a sponge with
alcohol, rather than wet cloth or other chemical liquid, to clean the mirrors. Be
careful, even light scratches reduce the output power of the laser. Mirrors need
cleaning, when a “halo” is noticeable around the beam, or an unusual high amount
of diffuse light can be seen inside the device.
