Before Use MT-40 Series
1. Operation Notice
1. As the microscope is a high precision
instrument, always operate it with care, and
avoid physical shake during the operation.
2. Do not expose the microscope in the sun
directly, either not in the high temperature, damp,
dust or acute shake. Make sure the worktable is
flat and horizontal.
3. When moving the microscope, use both hands
to hold its back hand-clasping ①and the front
base ②, and lay it down carefully (see Fig. 1).
★ It will damage the microscope by holding
the stage, focusing knob or head when
moving.
4. When working, the surface of condenser will
be very hot. Make sure there is enough room for
the heat dissipating around the condenser ③
(see Fig. 2).
5. Connect the microscope to the ground to avoid
lightning strike.
6. For safety, make sure the power switch ④is
at “0” (off) and power it off before replacing the
bulb or fuse, and wait until the lamp cools down
(see Fig. 2).
★ Bulb selected only: Single 3W LED light.
7. Wide voltage range is supported as 100~240V.
Additional transformer is not necessary. Make
sure the voltage is in this range.
8. Use the special wire supplied by our company.

2. Maintenance
1. Wipe the lens gently with a soft tissue. Carefully wipe off the oil marks and fingerprints
on the lens surfaces with a tissue moistened with a small amount of 3:7 mixture of alcohol and
ether or dimethylbenzene.
★ As the alcohol and ether is flammable, don’t place these chemical near to fire or fire
source. For example, when turning on or turning off the electrical device, please use these
chemical in a ventilated place.
2. Don’t use organic solution to wipe the surfaces of the other components. Please use the
neutral detergent if necessary.
3. If the microscope is damped by liquid when using, please power it off immediately and
wipe it dry.
4. Never disassemble the microscope, otherwise the performance will be affected or the
instrument will be damaged.
5. After using, cover the microscope with a dust cover.
3. Safety Sign

2-2 Assembling Steps
2-2-1 Assemble the Condenser
1. Rotate the coarse focusing knob①to raise
the stage to the highest position (see Fig. 3).
2. Rotate the condenser up-down knob②to
lower the bracket of condenser to the
suitable position.
3. Fully loosen the condenser lock-screw③.
4. Insert the condenser into the hole of stand
according to the arrowhead, until the
condenser is equal with the stand, and then
rotate the condenser to make the handle
frontward.
5. Tighten the lock-screw③of condenser,
then raise the condenser with the up-down
knob to the highest position.
2-2-2 Assemble the Objective
1. Rotate the coarse focusing knob to lower
the stage to a suitable position (see Fig. 4).
2. Install the objectives into the objective
nosepiece②from the lowest magnification
to the highest in a clockwise direction from
the rear.
★ When operating, first use the low
magnification objective (4X or 10X) to
search for specimen and focus, and then
replace with high magnification objective
to observe.
★ When replacing the objective, rotate the
objective nosepiece until it sounds
“ka-da”, to make sure the objective
wanted is in the center of optical path.

2-2-3 Assemble the Eyepiece
1. Take down the cover of eyepiece tube .①
2. Insert the eyepiece②into the eyepiece
tube, until touch the surface (see Fig. 5).
2-2-4 Connect the Power Cord
★Don’t use strong force when the power
cord is bended or twisted, otherwise it will
be damaged.
1. Make sure the power switch is at“0”(OFF)
before connecting.
2. Insert the connector①of power cord into
the power socket②, and make sure it connects
well (see Fig. 6).
3. Insert the other connector into the socket of
power supply, and make sure it connects well.
★Use the special wire supplied by our
company. If it’s lost or damaged, choose
one with the same specifications.
★Wide voltage range is supported as
100~240V.
★Connect the power cord appropriately
to make sure the instrument is connected
to ground.

3. Operation MT-40 Series
3-1 Set Illumination
1. Put through the power and turn on the main
power switch to“—”.
2. Adjust the light adjustment knob until the①
illumination is comfortable for observation.
Rotate the light adjustment knob clockwise to
raise the voltage and brightness. Rotate the light
adjustment knob counterclockwise to lower the
voltage and brightness (see Fig. 7).
Assemble the Mirror (Optional)
1. Turn off the power switch to “0”.
2. Loosen the hexagon screw①with the spanner,
to screw off the built-in Koehler illuminator
condenser②(see Fig. 8).
3. Screw on the mirror ③according to the
arrowhead pointed, and tighten the hexagon
screw①with the spanner.
4. Rotate the mirror stand④, to fill the field with
light.
3-2 Place the Specimen Slide
1. Push the wrench of the specimen holder
backwards.
2. Loosen the wrench , and clamp the①
slide by the clips while the cover glass②
faces up (see Fig. 9).
3. Rotate the X and Y-axis knob . Move③the
specimen to the center (alignment with the
center of the objective).
