I. Safety note

1. Carefully open the box, avoid the accessories, like lens, dropping to ground and being damaged.

2. Do keep the instrument out of direct sunlight, high temperature or humidity, dusty and easy

shaking environment. Make sure the stage is smooth, horizontal and firm enough.

3. If the bacterium solution or the water splash to the stage, objective or viewing tube, pull out the

power cord at once, and wipe up the microscope. Otherwise, the instrument will be damaged.

4. When running, the lamp house and nearby parts will be very hot. Please ensure there is enough

cooling room for them.

5. Make sure the instrument is earthed, to avoid lighting strike.

6. For safety, be sure the main switch is in “O” (off) state before replace the halogen lamp or the fuse,

then cut off the power, and do the operation after the lamp bulb and the lamp house completely

cool.

7. Check the input voltage: be sure the input voltage which signed in the back of the microscope is

consistent with the power supply voltage, or it will bring a serious damage to the instrument.

8. Use the factory supplied power cord, please.

II. Maintenance

1. All the lenses have been well checked and adjusted. It is forbidden to disassemble them yourself.

2. The nosepiece and coarse/fine focus unit have a compact and precise frame, please don’t

disassemble them as possible as you can.

3. Keep the instrument clean, wipe dust regularly, and be attention to avoid contaminating the

optical elements especially.

4. The contaminations on the prism, as finger mark and oil, could be gently wiped with a piece of soft

cloth or tissue paper, gauze which has been immersed in pure alcohol or xylene. ( note that the

alcohol and the xylene are all burned easily, do not let them near the fire, and use them in a

drafty room as possible as you can.)

5. Don’t use organic solvent to wipe the non-optical elements, when you need to clean, use the soft

detergent, please.

6. When using, if the microscope is splash by liquid, cut off the power at once, and wipe up the

moisture.

7. Do not disassemble any parts of the microscope. That will affect the function or decline the

performance of the microscope.

8. Place the instrument in a cool, dry position. After using the microscope, remember to cover it

with dust helmet. Do wait for the lamp house cooling completely before cover.

2-2 Installing steps

2-2-1 Installation Body’s Chassis

1. Installing the Mechanical Stage

Support Device

Before installing the device, be sure to

adjust the coarse focus knob①. Make the

guide board②(see figure 1) down to the

lowest position, so you can install the

mechanical stage support device easily.

Hold on the mechanical stage support

device (figure 2), place it from the top of

the guide board (figure 1), let the device

(figure2) falling free until it reach the limit

position. Use the hexagon wrench screw

down the locking block③, make the stage

support device (figure1) and the guide

board fixed together.

The mechanical stage ⑤have been

adjusted horizontally with ④and fixed

together before leaving factory. Do not

disassembly unless necessary, that may

affect the observation precision of the

instrument.

2-2-2 Installing and Replacing the Lamp

(figure4, 5)

Please use the specified halogen Lamp 6V30W①.

1. Hold the bulb①after you wrap it with gauze or

other protection materials, and then deeply insert

it into the lamp holder.

2. Replacing Lamp when using or soon after

When using, or soon after it is turned off, the

lamp, the lamp house and nearby parts will be

very hot and will cause serious burns. Please turn

the main switch②on “O” (off), pull out power

plug, and make sure the bulb, the lamp room and

periphery are all cool. Then, you can do your

replacing.

Please insert the lamp gently, or it will be

damaged by excessive extrusion

Do not touch the Halogen bulb with your bare

hands. It will shorten the service life or cause it

to burst. If you leave finger marks on the

surface carelessly, clean it with a dry soft

cloth.

2-2-3 Installing the Lamp House (figure 4, 5, 6)

Keep the bolt on the lamp house

(figure 4) in line with the jack on the back

of the microscope (like the show of figure

5), then pushing the lamp holder into the

illumination kits gently until they are

against each other (figure 6).

2-2-4 Installing the Objective

1. Adjusting the coarse focus knob until the

support device of the mechanical stage

reach its low limit position.

2. Wresting the lowest magnification

objective onto the nosepiece from the

left or the right side (figure 7), then

push the nosepiece clockwise, then

place other objectives by the sequence

of low to high magnification ( figure 8).

Installing objective this way will make

the change of magnification to be easier

while in using.

Clean the objective regularly, the

objective of the inversed microscope

is very sensitive to dust.

When operating, use 10 ×

magnification objective to search

specimen and focus firstly, then

replace with higher magnification

objective if necessary.

When replacing the objective, slowly

turning the nosepiece until you hear

“clicked”, that means the objective enter

the required position--the light path

center.
