CHAPTER 1
MAINTENANCE PROCEDURE
1)Fundamental handling
a.Read the instruction manual thoroughly, handle the microscope correctly.
b.Be sure to make a usual cleaning, especially after every use of microscope.
c.When handling the microscope, do not expose it to shock, moisture, heat and dust.
d.If the problem occurs, do not treat it in self-judgement.
2)Using and storing conditions
a.The microscope should be used under no vibration.
If it is placed in such environment as vibration, this causes disturbance and fatigue in observation and affects the photomicrography.
b.It should not be stored in high humidity.
Such condition causes fungus, corrosion on lens and rust on metal part. Therefore, special caution is exercised if stored in a long period of time.
c.Intense temperature change should be avoided.
Be careful not to place the microscope near window exposed to direct sunlight and air conditioner. When bringing it into warm room from cold storage location in winter, condensation occurs on lens and metal part, it causes fungus and rust.
d.It should be kept clean.
The microscope is required to keep away from dust that causes contamination, fungus on lens and failure of sliding part in the frame.
Be careful not to place it in the environment where the corrodent chemicals such as hydrogen sulfide, hydrogen fluoride and acid are handled.

HOW TO CLEAN THE EYEPIECE
1
Wrap a sheet of lens tissue around a cotton swab as illustrated. If the area to be cleaned is large, wrap the lens tissue looser and thicker. Otherwise, make a thin, tight wrap.
2
Dip the wrapped lens tissue in the cleaning solution, and wipe the eyepiece from the center towards the periphery in a circular motion.
Important notes:
1)Never rub the lens surface strongly.
2)Do not use the same lens tissue to clean more than one lens .
3)Do not moisten the lens tissue with an excessive amount of cleaning solution.
4)When cleaning with tweezers, be careful not to protrude its tip from the lens tissue.
