Somewhat generic machine with no manufacturer noted on the machine or in the manual. RuiDa ACS RDC644XG controller. I don't want to harm anything trying to remove the lens for cleaning. Online searches haven't led yet to this specific construction.

If you recognize the lens holder pictured in the attached, or generally know how to pull it apart for cleaning, I would appreciate the hints. Thank you.

p.s. -- The forum software reports all but one of my uploads is invalid. I've no clue how to fix that. Hopefully the one that works helps.

1. Press down on the blue ring (yellow circle in the picture) and pull out the air hose.
2. Unscrew the cone [nozzle] (yellow arrow in the picture). You might use the air fitting for leverage; a tool should not be necessary - should only be hand-tight. You might have to bend the red dot laser out of the way in order to rotate the cone. Or you could unscrew the air fitting from the cone so that it doesn't hit.
3. (Not shown) - there should be a ring holding the lens into the cone; unscrew the ring and the lens should drop out. Before removing the lens, note which side is up (flat side or curved side) - the difference is subtle.

When re-assembling, be sure the lens is seated properly and not at an angle. Tighten the ring holding the lens into the cone so that it is snug (don't want the lens to wobble) but not so tight as to crack the lens.

Thank you, that worked. I figured it simply unscrewed but, not being sure, I didn't want to apply a lot of force to something not meant to give.
