I. Safety Precautions

1. Be careful when moving the microscope, to avoid the lenses dropped or damaged.

2. Do keep the microscope 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.

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 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.

(Designated bulb: 6V30W Halogen Lamp)

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

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

II. 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 contamination 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

！Make sure that the input voltage is consistent with the power

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

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.

2-1 Mounting the Objectives

(Fig.2 and Fig.3)

1. Turning the coarse focusing knob①as the figure shows

till the nosepiece gets to its lower limit.

★For ensuring the safety of the instrument during

transportation, the nosepiece is located in the lowest

position and the tension adjustment collar②is adjusted

to an appropriate tension while leaving the factory.

2. Screw the lowest magnification objective on to the

nosepiece from the nearside, then turn the

nosepiece clockwise, mount other objectives according the

magnification sequence of low to high.

◎Mounting objective in this way will make it easier to

change magnification.

◎The objective can also be mounted through the opening

on the stage.

★Clean the objective periodically, for the objectives used in

the inverted microscope are susceptible to dust.

★Do cover all the unused holes③on the nosepiece with

dust caps, to prevent the dirt and dust from getting inside.

★When operating, use the low magnification objective

(4X or 10X) to search and focus the specimen at first, then

replace with the higher magnification objective if

necessary.

★When replacing the objective, turn the nosepiece slowly

until you hear “clicked”, that means the objective enters

into the right position, center of the light path.

2-2 Mounting Auxiliary Stage and the

Mechanical Ruler

◎Auxiliary stage can be installed in either side of the

stage to enlarge the stage surface. But you can’t install

the mechanical ruler at the same side.

◎Generally, the mechanical ruler will be installed at

the right side for comfortable operation.

1. Installing the auxiliary stage

First, Screw the clamping bolts into to the auxiliary

stage, then into the main mechanical stage from below

on right or left side; Tighten it with a screwdriver until

the auxiliary stage is securely attached.

2. Installing the mechanical ruler

Please install the ruler in the same way as the

auxiliary stage.

2-3 Installing and Replacing the Bulb

(Fig.4-Fig.7)

Please use the specified halogen Lamp 6V30W.

1. Pull out the lamp house①asshowninfig.4

2. Holding the bulb ①with a piece of gauze or other

protection materials, insert the bulb pins straight and

fullyintothepinholes③on the lamp house. (Fig.5)

3. Bulb replacement during use or right after use. The

bulb, the lamp house and nearby parts will be very hot.

Please set the main switch to “O” (off), disconnect the

power cord, and make sure the bulb, the lamp house

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 bare hands. It

will shorten the service life or cause it to burst. If you

leave fingerprints on the surface carelessly, clean it

withapieceofdrysoftcloth.

4. Align the socket①with pins③,and the bolts②with the

jacks④.then push the lamp-house all the way into

place.(Fig.6-7)

2-4 Installing the Stage Center Plate

（Fig.8）

1. When using the glass stage ①, there is no special

requirement, you just need to place it in the center of the

mechanical plain stage.

2. Install the stage center plate on to the stage opening.

2-5 Installing the Eyepiece (Fig.9)

1. Remove the cap of the eyepiece tube.

2. Insert the eyepiece into eyepiece tube until they are

against each other.
