CARE AND CLEANING
The M7000 Series microscope is designed to function with minimal
maintenance, but certain components should be cleaned frequently to
ensure ease of viewing. The power switch should also be turned off or
unplugged when the microscope is not in use.
CLEANING – The front lens of the objectives (particularly the 40XRD and
100XRD) should be cleaned after use. First brush with a soft, camel hair
brush or blow off with clean, oil free air to remove dust particles. Then
wipe gently with a soft lens tissue, moistened with optical cleaner
(eyeglass or camera lens) or clean water. Immediately dry with a clean
lens paper.
CAUTION - Objectives should never be disassembled by the user. If
repairs or internal cleaning should be necessary, this should only be done
by qualified, authorized microscope technician. The eyepiece(s) may be
cleaned in the same manner as the objectives, except in most cases
optical cleaner will not be required. In most instances breathing on the
eyepiece to moisten the lens and wiping dry with a clean lens tissue is
sufficient to clean the surface. Lenses should never be wiped while dry
