3.
Look through the eyepieces and rotate the focus control knob to
focus the specimen in the field of view.
4.
Grasp the eyepiece tubes and move them either closer together or
farther apart, to change the interpupillary distance to obtain a clear
image. Note, if two separate images are observed, the eyepiece
tubes are too far apart and should be moved together. If two
overlapping images are seen, the eyepiece tubes are too close
together and should be moved apart.
5.
Close your left eye and adjust the focus controls so the image is
in sharp focus, while viewing with the right eye only.
6.
Close your right eye and while viewing with the left eye
only, adjust the diopter ring on the left eyetube to bring the image
of the specimen into sharp focus. The optical system is now
adjusted to your particular vision.

Rotate the black magnification knob to lowest magnification. Only
minor refocusing using the focusing control knob should be required.
Your microscope is now parfocalled.
SERVICE AND CLEANING
Use and store your instrument in a dry environment. When not being
used, microscopes should be stored with dust covers in place and
illuminators turned off. Avoid direct sunlight, high temperatures,
moisture, smoke, and fungus. Your Swift stereo microscope is
designed to function satisfactorily with only ordinary maintenance.
The instrument should be periodically serviced by a qualified,
authorized service technician, who will clean, re-lubricate and
perform routine adjustments. Eyepieces should be cleaned as often
as necessary to allow unobstructed viewing. Clean the eyepieces by
brushing away dust particles using a soft camel hair brush or with air
pressure, then moistening the lens by breathing onto it. Wipe the
lens carefully with quality lens tissue. If dirt or other foreign matter
still remains, it may be necessary to use water or optical cleaner
(eyeglass or camera lens). Note: the lens tissue should be moistened,
not saturated, for cleaning, after which the lens should be dried
using a quality lens tissue. Painted surfaces should be cleaned with
soapy water or mild non-abrasive cleaners and a soft cloth. Do not
use solvents on painted surfaces.
Unauthorized personnel should never disassemble lens assemblies or
other precision components.
