Important Notes

Do not install the air assist device on the laser module without an external air pump, otherwise the laser module will be damaged during use!

If the laser module is not used for a long time or is used for more than 30 hours, clean the lens with medical alcohol and cotton swab. Unclean lenses can weaken the power of the laser.
