BASIC MAINTENANCE
#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 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
To gain access to the #3 mirror (3) and the focus lens (4),
hold the front cover (2) with one hand, and remove the
three thumbscrews with the other hand. Pull the front
cover straight out. 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.
Beam Window
The beam window is where the laser beam enters into the engraving area. It
is located in the upper left hand corner of the engraving area against the back
wall and is yellow in color. It is only necessary to clean the front side of the
beam window. Do not remove the optic to clean it, simply clean it in the same
manner as the #2 mirror.
