How to Clean Laser Lens and Mirrors

    b. The wiping process should be handled gently to prevent falling;
    c. When installing the focusing lens, be sure to keep the concave side down
    d. For the carbon dioxide cutting machine, there is no need to disassemble the first reflector and the second reflector when cleaning.
