OBSERVING OPERATION
1. Press the power switch on the side "I". The illumination power supply is now on.
2. Set the 10X objective into operation position by turning the nosepiece. Focus in on
the specimen which is on the stage.
3. Adjust interpupillary distance and diopter while looking through binocular.
4. Adjust the up & down position of the condenser, light control and aperture diaphragm
in order to getting satisfied luminal effect. When watching with 4x or 10x objective, bring
down the condenser propriety to get symmetrical light. When watching with 4x objective,
put the Secondary Collector in observation position.
5. While interchange other objectives turn the nosepiece and refocus slightly with the
fine focusing knob. When use the 100X objective, .may be sure to put a drop of cedar
wood oil between the objective and the specimen.
How to use your microscope
1. Adjustment of interpupillary distance
Put the specimen on the stage and bring the specimen
into focus. Adjust the interpupillary distance of binocular
until the right-left field of view can become one. (Fig.4)
2. Adjustment of diopter
Put the specimen on the stage. Turn the 40X objective to working position. First,
observe at right column with right eye, adjust coarse-fine focusing knob to image
clearly. Next, observe at left column with left eye. Now adjust the diopter (I) until the
image is clear. (Fig.4)
3. Coarse/Fine focusing
The microscope uses a coaxial coarse/fine focusing
mechanism. The adjustable tensional knob (D) is used
for adjusting the tension of the coarse focusing knob
(3) to prevent the stage from naturally sliding down.
The limit knob (D) prevents accidental
specimen/objective contact. Number two (2) is the
fine focusing control. (Fig.5)

4. Stage
The convenient specimen holder (1) on the stage is
used for holding slide glass. (2) The lengthwise
knob (3) and the cross knob (4) are coaxial. These
move the stage expediently. (Fig.6)
5. Elevated condenser
The condenser is moved up or down by turning the
up-down knob (1). The condenser can be removed
easily if you unscrew the condenser holding screw.
(2) The filter plate is placed on the filter seat (6).
(Fig.7)
6. Power switch and adjustable brightness
Turn on the power switch (3) and adjust the light control (4) until image can be observed
comfortably. (Fig.7)
Note: Don‘t let the light control at the lightest position so long that reducing the life-span
of the bulb.
7. Aperture diaphragm
The aperture diaphragm lever (5) can be turn to
adjust NA of the illumination system. (Fig.7)
Remove the eyepieces and watch through the
eyepiece tube. The adjusting screw is used while
the diaphragm image is eccentric with the objective
pupil. (D) Turn the aperture diaphragm for getting an
image with acceptable contrast. Usually, adjusting
diameter of the aperture diaphragm image (2) to 7080 percent of the objective pupil works best. (Fig.8)

8. EXCHANGE THE BULB AND FUSE (Fig.9, 10)
Switch off the power supply and pull
out the plug of electrical wire.
Incline the microscope; loosen the
screw (3) of the lamp access door (1)
on the bottom of your microscope.
Remove the lamp access door from
bottom.
Pull out the old bulb (4) from lamp
base (5).
Insert the new bulb (4) into lamp base.
(5). Note: Be care to install the new
bulb without touching the glass with your fingers.
Reinstall the lamp access door. (3 on bottom with screw 4)
Plug in electrical wire. Turn on the power supply. Set an objective lens into light
path. Adjust condenser upwards and downwards to make light enter view field. If
light spot is offset from the center of view,
loosen the screw (2) slightly and move the
lamp base. (1) Adjust the lamp spot into
center, and then tighten up the screw. (2)
Pull out power supply plug 2 from socket and
take out socket of fuse 1. Changing the fuse.
Install socket of fuse and plug again. (Fig.10).
Specification of fuse: 0.5A
9. How to use the polarization flake (optional) (Fig.3)
Insert the polarization flake (4), put the polarizer (9) on the collector, and turn the field
diaphragm to maximum, turn the polarizer (9) to observe the polarized light.

MAINTENANCE
1. Clean the lens
Clean the lens by lens tissue or soft fabric moistened with mixed liquid of alcohol/ether
or diethyl benzene. Clean off the oil on the 100X objective whenever you are finished
operating.
2. Clean the painted parts
The dust on the painted parts can be removed by a soft cloth. To remove grease spots,
a gentle, non abrasive cleaner is recommended. Do not use organic solvents such as
alcohol, ether or any other thinner’s for cleaning the painted parts or plastic
components.
3. Avoid disassembling the microscope
Being a precise instrument, do not disassemble the microscope. Disassembly may
cause serious damage to its performance.
4. When not in use
Cover the microscope with polymethyl methacrylate or polyethylene and places where
there is dry and modules. Suggest that storage all objectives and eyepieces in closed
container with drying agent.
