Maintenance
Optics
A visual inspection of the #2 and #3 mirrors, beam window and focus lens should be performed at least once a day.
CAUTION: Do not clean an optic that is visually clean. Excessive cleaning can damage the
optic. To prevent contamination, wash your hands thoroughly before cleaning any optic.
Never touch any optic with your ngers. The acids from your skin can destroy the optical
coatings.
Never clean any optic right after engraving or cutting because the optic may be hot and
the cool lens cleaning solution may thermally shock the optic and crack it.
#2 Mirror
To gain access to the #2 mirror, the mirror cover must be removed. Remove the thumbscrew and slide the
cover to the right and then lift the cover straight up.
Inspect the #2 mirror and clean it only if there is debris present. To clean the #2 mirror with a cotton swab,
moisten the cotton swab with the lens cleaning solution supplied with the laser system. Do not use other types
of cleaners or solutions. Gently roll the cotton swab across the mirror once. Do not drag the swab or roll it
back and forth as this can scratch the mirror. If the mirror did not come clean, use a fresh cotton swab and
repeat the procedure.
Do not be concerned about small pieces of lint that come o of the cotton swab. You can cause more damage to
the mirror by trying to remove the lint than by leaving it alone.
#3 Mirror and Focus Lens

To gain access to the #3 mirror (3) and the focus lens (4), hold the front cover (2) with one hand and 2.
remove the three thumbscrews with the other hand. Pull the front cover straight out.
