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. Be careful not to spill any liquid –– such as a culture solution –– on the unit. If you do spill anything, immediately set the
main switch to “ ” (OFF) and unplug the power cord. Then wipe away any liquid on or under the objectives.
4. If no objectives are mounted, be sure to cover the objective mounting threaded positions on the revolving nosepiece to
prevent and dust and spilled culture solution from getting on the lenses inside.
5. Do not disassemble any part of the microscope as this could result in malfunction or reduced performance.
6. When not using the microscope, keep it covered with a dust cover. Make sure the lamp socket is cool before covering the
microscope.
7. Using a device that radiates ultraviolet light such as a germicidal lamp near the microscope may discolor (yellow) parts
of the microscope surface. The amount of discoloration depends on the radiation intensity of the ultraviolet light and the
distance between the microscope and radiation source. When not using the microscope, cover it with the dust cover. We
recommend that you also cover the microscope with an impermeable sheet.
8 When disposing of the microscope, check the regulations and rules of your local government and be sure to observe
them.
