Care and Maintenance

Lens and filter cleaning

Do not let dust, fingerprints, etc. get on the lenses and filters. Dirt on the lenses, filters, etc.

will adversely affect the view of the image. If any of the lenses or filters gets dirty, clean it as

described below.

• Use a blower, etc. to blow away dust. If this is not sufficient to remove the dust, brush

away with a soft brush or gently wipe away with gauze.

• To remove fingerprints or grease, use a piece of soft, clean cotton cloth, lens tissue, or

gauze moistened with absolute alcohol (ethyl alcohol or methyl alcohol). However, do

not wipe twice with the same part of the cloth.

• Use petroleum benzine to clean off immersion oil. Wiping with absolute alcohol (ethyl

alcohol or methyl alcohol) will complete cleaning.

If petroleum benzine is not available, use methyl alcohol. Note that the cleaning

effectiveness of methyl alcohol is low and it will be necessary to repeatedly wipe.

(Normally, wiping three or four times is sufficient.)

• Be sure to use petroleum benzine only for cleaning off immersion oil from objectives.

Do not use it for cleaning eyepiece tube entrance lenses, filters, etc.

• Absolute alcohol and petroleum benzine are both highly flammable. Be careful when

handling them, when around open flames, or when turning the power switches ON and

OFF.

• Follow the instructions provided by the manufacturer when using absolute alcohol and

petroleum benzine.

Cleaning painted components

Do not use organic solvents such as alcohol, ether or paint thinner on painted components,

plastic components or printed components. Doing so could result in discoloration or in peeling

of the printed characters. For persistent dirt, dampen a piece of gauze with neutral detergent

and wipe lightly.
