1. Safety Symbols
symbol
explanation
Indicates that the surface becomes hot, and should not be touched with bare
hands。
Before use, carefully read the user manual .Improper use could result in
personal injury to the user and/or damage to the equipment.
Indicates that the main switch is ON.
Indicates that the main switch is OFF.
2. Safety Precautions
1. Be careful when opening box to keep objectives from dropping and damage, avoid
objectives from sweat and fingerprints.
2. Do keep the metallographic device out of direct sunlight, high temperature or humidity,
dusty and easy shaking environment. Make sure the stage is smooth, horizontal and firm
enough.
3. When moving the instrument, grip two sides of the bottom of the microscope with your
two hands.
★DO NOT hold the coarse-fine movement hand wheel or the lamp house or the
microscope may be damaged.
4. Please ensure enough cooling room for power box and keep away from power wires.
5. When running, the lamp house and nearby parts will be very hot. Please ensure 10cm
cooling room for them.
6. Make sure the instrument is earthed, to avoid lighting strike
7. For safety, be sure the main switch is in “O”(off) state and cut off the power supply
before replacing the bulb or the fuse. If you replace the bulb during use or right after use,
allow the lamp bulb and the lamp house to cool completely before touching.
8. Use the dedicate power wires。
9. When camera or TV lens is needed, make sure the adding weight is less than 2.8kg.

3. Maintenance and Care
1. All the lenses have been adjusted properly; do not dismount them by yourself please.
2. The nosepiece and coarse and fine focusing parts are so delicate that it is forbidden to
disassemble them carelessly by yourself.
3. Keep the instrument clean ,and do not pollute the optical element when wiping away the dust
on the instrument.
4. The contaminations on the prism, like fingerprints and oil smudges, could be gently wiped
with a piece of soft cloth or tissue paper, gauze which has been immersed in pure alcohol or
ether. (Note that the alcohol and ether are highly flammable, do keep them away from
the fire or potential sources of electrical sparks, and use them in a drafty room as
possible as you can.)
5. Do not attempt to use organic solvents to clean the microscope components other than the
glass components. To clean them, use a lint-free, soft cloth slightly moistened with a diluted
neutral detergent.
6. When using, if the microscope is splashed by liquid, cut off the power at once, and wipe away
the splash.
7. Do not disassemble any parts of the microscope, as this will affect the function or reduce the
performance of the microscope.
8. Place the instrument in a cool, dry position.After using the microscope, remember to cover it

2-2Assembly Steps A13.1005
2-2-1 Install L-plate（pic.1）
Fix the L-plate and the fine-coarse
movement component together by 4
matched bolts and washers.
2-2-2 Install supporting component
（pic.2）
Insert the supporting component to the
corresponding holes on the L-plate and
fix it on the fine-coarse movement
component by 4 matched bolts and
washers.
2-2-3 Install fine-coarse movement
component（pic.3）
Stack the fine-coarse movement
component on the column of the
platform and screw the fixing bolt ○ 1 .
If the specimen is too high, we can
stack the locking collar ○ 2 on the
column before the install of
fine-coarse movement component.

2-2-4 Install connecting plate（pic.4）
Put the connecting plate on the L-plate
and fix it by 4 matched bolts. Make sure the
locating surface ○ 1 is adjacent with the
surface ○ 2 of the L-plate
2-2-5 Install converter and objective
（pic.5）
1. Insert the converter to the socket on the
connecting plate by path shown in pic.5
and tighten the bolt○ 1 by a hexagon
screwdriver to fix it.
2. Screw the objectives to the holes on the
converter in sequences.
2-2-6 Install metallographic device
（pic.6）
★put the swallow tail of the metallographic
device in the corresponding holes on the
connecting plate and tighten the bolt○ 2 in
pic.5.
★If it is a bright and dark field
metallographic, we should insert the
lamp house into the back of the
metallographic device and tighten
bolt○ 1 to fix it.

3. Adjustment and Operation A13.1005
3-1Connect power source and regulate
light（pic.1,pic.2）
1. Connect the air plug of halogen lamp
house with the aerial socket○
1of the
power box, plug one head of power line to
socket○
2and the other head to the power
supply. Toggle the converter switch○
3to
proper position according the power
demand of location.
2. Make sure the light adjust knob○
5in a
minimum position and toggle the main
switch○
4in the front of power box to the
“－” position. (It’s only need to plug
the adapter to the socket when using
LED house)
3. Turn the knob○
5to the MAX position to
increase the voltage and the brightness of
lamp house.
3-2 Sample placement（pic.3）
Place the sample○
1on platform○ 2.
○sample should be plat or parallel.
Besides, reflected light should not
entrance the objective otherwise the
observation will fail.
Be careful when convert objectives. The
objective may touch the sample when
converting objective after using a short
working distance objective.

3-3 Adjustment of coarse focus hand
wheel（pic.4）
The loose condition of coarse focus hand
wheel can be adjusted by turning the adjusting
ring○ 1 .
The coarse focus hand wheel is in a loose
state when delivered, a heavy force is needed
to rotate the hand wheel.
3-4Adjustment of pupil distance（pic.5）
The range of pupil distance is 47mm～78mm.
when observing with both eyes, hold and
rotate the prism table to adjust the pupil
distance until the left and right field of view
coincided.
3-5 Visibility adjustment（pic.6）
1. Observing with right eye, rotate the focus hand
wheel until the sample is imaged clearly
within the eyepiece.
2. Use left eye to observe, adjust the visibility
ring○ 1 until the sample is imaged clearly
within the left eyepiece.

3-6 3-gear light path switch（pic.7）
1. When not using cameras, totally push in the
light path switch rod and observing by
eyepiece. Use the 10×objective to focus, first
descend the focusing component and find the
image in the 10×eyepiece, then turn the fine
focusing hand wheel until clearly imaged.
Convert the objective will not touch and
damage the sample because of the par
