Care and Maintenance
Cleaning the Lenses
• Dust is best removed using a soft brush or gauze.
• More persistent dirt, such as fingerprints, grease and oil, may be removed with lens tissue (or soft
cotton, gauze) lightly moistened with absolute alcohol (anhydrous ethyl alcohol or methyl alcohol;
do not use rubbing alcohol).
• To clean immersion oil off the oil-immersion type objective, use lens tissue, soft cotton or gauze
lightly moistened with petroleum benzine. If petroleum benzine is not available, use methyl
alcohol. In this case, you need to wipe three or four times because the detergency of the methyl
alcohol is somewhat weak.
• Absolute alcohol and petroleum benzine are quite inflammable. Take great care when handling
them and when turning the power switch on and off. Be very careful with fire.
Cleaning the Microscope
• Avoid using organic solvents (such as alcohol, ether, thinner, etc.) to clean the microscope. Doing
so could result in discoloration of the painted or plastic parts or in peeling of the printed characters.
• We recommend that you use a silicon cloth to wipe down the painted or plastic parts of the
microscope.
• More persistent dirt may be cleaned using gauze lightly moistened with mild detergent solution.
When Not in Use
• When the microscope is not in use, cover with the vinyl dust cover, and store it in a dry place
where mold is not likely to form.
• Make sure that the power switch is off (turned to
covering with the vinyl dust cover.
• We especially recommend that the objectives and eyepieces be kept in a container (such as a
desiccator) with desiccant in it.
Periodical Inspections
• To maintain the performance of the microscope, periodical inspections and maintenance are
recommended.
• For details, contact your nearest Nikon representative.
