4. Getting Ready
A microscope is a precision instrument. Handle it with care and avoid subjecting it to sudden or
severe impact.
Do not use the microscope where it is subjected to direct sunlight, high temperature and humidity dust
or vibrations.
Do not turn the zoom adjustment knobs beyond the stopper positions. Otherwise, the internal
mechanism may be damaged.
Do not turn the left and right zoom adjustment knobs in the opposite directions, as this will result in a
failure.
5. Maintenance and Storage
To clean the lenses and other glass components, simply blow dirty away using a commercially
available blower and wipe gently using a piece of cleaning paper (or clean gauze). lf a lens is stained
with fingerprints or oil smudges, wipe it gauze slightly moistened with commercially available absolute
alcohol.
Since the absolute alcohol is highly flammable, it must be handled carefully.
Be sure to keep it away from open flames or potential sources of electrical sparks - for
example, electrical equipment that is being switched on or off. Also remember to
always use it only in a well-ventilated room.

12
HSZ-600 STEREO MICROSCOPE
Do not attempt to use organic solvents to clean the microscope components other than the glass
components because they use plastic resin materials extensively To clean them, use a lint-free, soft
cloth slightly moistened with a diluted neutral detergent.
Do not disassemble any part of the microscope as this could result in malfunction or reduced
performance.
When disposing of the microscope. Check the regulations and rules of your local government and be
sure to observe them.
6. Standard Components
Standard composition of stereomicroscope is as following.
Microscope body (HSZ-645 or HSZ-660 or HSZ-645TR)

9-1. Stand
9-1-1. Using the Stage
When reflected light illumination is used, the stage plate can be placed either the white or black surface
facing up depending on the specimen.
When transmitted light illumination is used, use the transparent glass stage plate.
9-1-2. Adjusting the Focus Adjustment Knob Tension (Fig.1)
Hold the left and right focus adjustment knobs①with both hands, fix the left knob and rotate the right
Knob. The rotation tension of the knob is increases or decreases according to the direction in which the
right knob is rotated.
If the rotation tension is increased too much, accurate focusing is not possible and the mechanism may
be damaged.
Fig. 1
This operation is intended to facilitate the rotation of the knobs while preventing
spontaneous drop of the microscope body. It is recommended to set the knob tension
to a slightly higher level than the point where spontaneous drop occurs.

9-2-3. Using the Eye Shades (Fig.4))
[When Wearing Eyeglasses]
Use with the eye shades in the normal, folded-down position. This will prevent the eyeglasses from being
scratched.
Diopter scale of the 10X eyepieces
The valid range of the diopter scale is between -8 and +5 but a slight margin is added to
it. Therefore, the diopter value may exceed +5 or -8 when it is adjusted to the maximum.
ln this case, whether the diopter value is over -8 or under +5 can be identified by the
length of the eyepiece.

9-2-4. Using an Eyepiece Micrometer Disk (Fig.5)
1) Rotate the disk-mounting ring①of the eyepiece counterclockwise to remove.
2) Prepare an eyepiece micrometer disk②, remove dust and dirt from its surface, and fit it into the disk-
mounting ring①so that the engraving on the micrometer disk faces downward.
3) Gently screw in the disk-mounting ring①incorporating the eyepiece micrometer disk into the eyepiece.
Turn the ring clockwise to attach it firmly.
* When the eyepiece micrometer disk is not used, store it by wrapping in a clean, soft cloth.
