Do not remove eyepieces or objective lenses to clean. Clean only the outer lens surface. Breathe on lens
to dampen surface, then wipe with lens paper or use a cotton swab moistened with distilled water.
Wipe lens with a circular motion, applying as little pressure as possible. Avoid wiping dry lens surface as
lenses are scratched easily. If excessive grease or dirt gets on the lens surfaces, a small amount of windex
or distilled water can be used on a cotton swab or lens tissue. To clean objective lenses, clean front lens
element only, following the same procedure.
NOTE: Fingerprints or other matter on the front lens element of the objective lens is the single most
common reason that you will experience difficulty in focusing the microscope. Before
having costly servicing done, or before returning for warranty repair, we ask that you first make
certain to examine the front lens element with a magnifying glass or eye loupe for the presence
of such contaminants. If a microscope is returned for warranty repair, and it is determined that such
contaminants are the problem, this is not covered under warranty and we will submit a cost estimate for
cleaning.

Mechanical Maintenance
a.
The rack stop screw has been pre-adjusted at the factory and should not require
re-adjustment. However if you do attempt re-adjustment, note the following procedure:
Loosen round knurled locking nut by turning counter-clockwise. Then loosen stop screw. With the
fine focus adjustment at mid-range, focus on standard slide until sharp image is achieved. Rotate
rack stop screw in clockwise direction until tight. Lock into position with the locking nut. A needle
nose pliers might be needed to loosen the round locking nut.
