Replacing the Lens (Continued)
The lens is small, about 20mm in diameter and two distinct sides, one concave and one convex. When re-
installing the lens, the convex side (curved/ rounded side) should always face up in the laser head. (towards
the sky, not towards the work table)
The lens assembly consists of two main parts, the lens housing and the nozzle. There are also three
components of the lens housing which are the lens, washer and slotted ring nut.
To remove the lens or replacement of cleaning, loosen the friction set screw on the main lens housing while
holding the lens tube to ensure that it does not fall and get damaged.
Handle the lens carefully, using a lens cleaner/wipes to clean both sides of the lens. Lens paper works well
and should show a brown residue after cleaning. Make sure to place the concave side down towards the
working platform when reassembling, convex side always faces the laser beam. Rubber O-ring first, then the
lens and ring nut. Don’t over tighten ring nut, just snug it up against the washer, and then a quarter turn
more.
Burned lenses are a common problem for new users of any laser machine. Make sure to clean it often,
especially if cutting on a regular basis. Keeping the lens clean will make it last a longer & more efficient.
Using the included tool, place it in the slots of the lens retaining ring. Twist counter clockwise to loosen.
Remove lens and rubber sealing gasket for cleaning. Remember when replacing the curved side is facing up.
Flat side down.
