BASIC MAINTENANCE
Section 4-2
Optics
A visual inspection of the #2 and #3 mirrors, beam window, and focus lens should be performed at least
once a day.
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 fingers. 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
Locate the #2 Mirror Holder located on the left side of the X-rail.
Grasp its protruding red handle with your thumb and forefinger
and slide it out (Fig 1). Turn the #2 Mirror Holder over and
inspect the optic for visual contamination. Clean as necessary.
To re-insert the #2 Mirror Holder, slide it into the mounting slot
until it stops.
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.
Figure 1
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 off of the cotton swab. They will be
vaporized as soon as the laser hits it. You can cause more damage to the mirror by trying to remove the
lint than by leaving it alone.
#3 Mirror and Focus Lens
Figure 2 Figure 3 Figure 4
To gain access to the #3 mirror and the focus lens, remove the cover in by pulling the cover straight out
(Fig 2). After cover has been removed the lens assembly kit will be exposed (Fig 3). Hold the cover with
one hand, and remove the 5 thumbscrews with your other hand (Fig 3). Pull the front cover straight out
(Fig 4). The #3 mirror and the focus lens are both mounted to the front cover.
Tilt the front cover enough to enable you to apply the lens cleaning solution directly to the #3 mirror and to
the focus lens. Flood the reflective surface of the #3 mirror with the solution. If heavy debris is present,
let the solution soak in for a minute. Roll a fresh cotton swab across the mirror in one direction. Use a
fresh swab for each pass. Be gentle when cleaning the optic to avoid scratching the surface. Repeat this
procedure for the focus lens but make sure you clean both sides of the lens.
