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. When moving the instrument, please use two hands to grip the two sides of the microscope body.

4. 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.

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

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 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.

8. 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.

9. 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. Installation

For installation instruction, take BS-2040FB(LED) biological microscope for example:

●BS-2040FB(LED) LED Fluorescent Microscope=biological microscope BS-2040B+FL-LED

attachment

Fluorescent Microscope Assembly：

1) Loosen the clamping screw①on biological microscope BS-2040B and remove the binocular viewing

head from the body of microscope by revolving it counterclockwise by 90°.

2) Insert the main body of fluorescent attachment into the upper part of the microscope BS-2040B ,adjust

the orientation and tighten the clamping screw①.

3) Insert the binocular viewing head into the main body of the fluorescent attachment, adjust its

orientation and tight the clamping screw②to fix the head.

4) Replace the original biological objective with special fluorescent objectives④.

NOTE:

1. Both top and bottom illumination system can be used for fluorescent microscope. But

for this fluorescent attachment, only top illuminator can be used while bottom

illuminator is closed. The filter subassembly is set at the middle position (B excitation

state); For normal biological observation, use bottom illuminator while top

illumination is closed. The filter subassembly is set at empty position.

2. It is necessary to adjust biological microscope system firstly before fluorescent

attachment is used.

3. Adjustment and Operation

3.1 Fluorescent Operation System

3.2 Fluorescent Microscope Operation (Fig.4, Fig.5)

1. Set the filter subassembly①at the middle position to engage B excitation filter into the light path.

2. Connect the power supply onto the microscope, turn on the main switch and adjust brightness adjustment

knob④to a proper intensity.

3. Adjust the condenser focusing knob③to make the field of view full.

4. Place the specimen on the stage for observation and operation.

5. During observation, use the light barrier lever②to obscure the light path so that the main switch is not

open and closed frequently.

●The standard FL-LED fluorescent attachment are equipped with b-excitation filter (in the middle

position). If you need other types of filters, please purchase separately.

3.3 Precautions for Operation

1. Check that the power voltage and frequency is consistent with the product requirements.

2. Ensure that the plug is inserted fully and well connected.

3. If only for transmitted light observation (biological microscopy), pull out the filter subassembly or

push inward it to engage the empty position into the optical path.

4. When Using the oil immersion objective (100x), be sure to use specified immersion oil for

fluorescent observation.

5. If you interrupt observation within a short time, use the light barrier to block light.

1-2-1 Installing the Mechanical Stage

Support Device

Before installing the device, be sure to adjust

the coarse focus knob. Make the guide

board (see Fig.7)down to the lowest

position, so you can install the mechanical

stage support device easily.

Hold on the mechanical stage support device

(Fig.8), place it from the top of the guide

board (Fig.7), let the device (Fig.8) falling

free until it reach the limit position. Use the

hexagon wrench screw down the locking

block, make the stage support device

(Fig.7) and the guide board fixed together.

The mechanical stage have been adjusted

horizontally and fixed together before

leaving factory. Do not disassembly

unless necessary, that may affect the

observation precision of the instrument.
