IMPORTANT

The BXFM focusing unit can be used as the basis for installing modules such as reflected light illumina-

tion equipment, objectives, eyepieces and observation tube for construction of a microscope system.

The BXFM can be installed on the exclusive stand or on your microscope.

SAFETY PRECAUTIONS

1. Install the microscope on a sturdy, level table or bench so as not to

block the air vents on the underside of the base.

2. When combing the stand (U-ST), install the BXFM so that it forms an

angle of ±30° with respect to the pillar as shown in Fig. 1.

The compact brightfield illuminator (U-KMAS) should be installed so that,

when it is seen from the front, the lamp housing is located on its right

side.

3. When carrying the BXFM, hold the stand by the bottom with one hand

as shown in Fig. 2, and hold the focusing block with the other hand.

# Do not hold the BXFM by the coarse/fine adjustment knobs or lamp

housing. Otherwise, the microscope may be damaged.

4. The surface of the lamp housing @ on the rear of the microscope be-

comes very hot. When installing the microscope system, leave spaces

of more than 10 cm around the lamp housing, particularly on the top

and bottom.

Do not install the lamp housing up side down or with the side facing up.

Also do not use the microscope in a tilted attitude.

5. The TH4 power supply is air-cooled so it becomes during operation.

When installing it, leave spaces of more than around it. Also make sure

to distribute cables away from the power supply.

6. Be sure to set the main switch to “ ” (OFF) and unplug the power cord

before replacing the light source bulb. (P. 26)

7. Always use the power cord provided by Olympus. If no power cord is

provided, please select the proper power cord by referring to the chapter

“PROPER SELECTION OF THE POWER SUPPLY CORD” at the end of

this instruction manual. If the proper power cord is not used, product

safety and performance cannot be guaranteed.

8. Always ensure that the grounding terminal of the microscope and that

of the wall outlet are properly connected. If the equipment is not grounded,

Olympus can no longer warrant the electrical safety and performance of

the equipment.

· With the combination using the BXFM-ILH illuminator mounting holder,

do not use the U-ST stand because this makes the system unstable.

· The system can be stabilized by using the SZ-STL large stand, but the

image may fluctuate or blur irregularly when a 50X or higher-power ob-

jective is used.

· It is recommended to fabricate an exclusive clamping tool which uses

the support mounting hole (P. 20) or module mounting screw hole of the

BXFM-F focusing unit.

Symbol Explanation

The following symbols are found on the microscope. Study the meaning of the symbols and always use the equip-

ment in the safest possible manner.

Indicates that the surface becomes hot, and should not be touched with bare hands.

Before use, carefully read the instruction 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.

Warning engraving/stickers are placed at parts where special precaution is required when handling and using the

microscope. Always heed the warnings.

total weight limit of the modules added to the standard combination as

shown below.

1Getting Ready

1. A microscope is a precision instrument. Handle it with care and avoid subjecting it to sudden or severe impact.

2. Do not use the microscope system where it is subjected to direct sunlight, high temperature and humidity, dust or

vibrations. (For the operating conditions, refer to chapter 7, “SPECIFICATIONS”.)

3. One intermediate attachment can be used by installing U-CA magnification changer or U-EPA2 eyepoint adjuster above

the reflected light illuminator.

2Maintenance and Storage

1. To clean the lenses and other glass components, simply blow dirty away using a commercially available blower and wipe

gently using a piece of cleaning paper (or clean gauze).

If a lens is stained with fingerprints or oil smudges, wipe it gauze slightly moistened with commercially available absolute

alcohol.

Since the absolute alcohol is highly flammable, it must be handled carefully.

Be sure to keep it away from open flames or potential sources of electrical sparks –– for example, electrical

equipment that is being switched on or off.

Also remember to always use it only in a well-ventilated room.

2. 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.

3. Never attempt to disassemble any part of the microscope system.

4. When not using the microscope, set the main switch to “ ” (OFF). After making sure the lamp housing has cooled down

sufficiently, cover it with a dust cover.

5. When disposing of this product, check the regulations and rules of your local government and be sure to observe them.

3Caution

If the microscope is used in a manner not specified by this manual, the safety of the user may be imperiled. In addition,

the equipment may also be damaged. Always use the equipment as outlined in this instruction manual.

The warning, caution and other notes in this manual use the following symbols.

: Indicates that failure to follow the instructions in the warning could result in bodily harm to the

user and/or damage to equipment (including objects in the vicinity of the equipment).

# : Indicates that failure to follow the instructions could result in damage to equipment.

} : Indicates commentary (for ease of operation and maintenance).
