Maintenance
this instrument should be kept in a cool, dry place free from direct sun, dust, alkali
and acid fumes as well as moisture.
do not disassemble any of the lenses since they have all been properly aligned
at the factory. the glass surfaces of the lenses should be cleaned with lens tissue
or brushed with a soft camel-hair brush. Any dust which has fallen on lens exterior
surfaces may be blown away with a commercial grade clean dust spray.
if stains deposit on exterior surfaces of the lenses, clean them gently using a mild
soap solution with a lint free cloth. industrial solvents should not be used since they
may penetrate to the inside of the lens components and dissolve the lens cement.
When cleaning and lubricating the mechanical parts, special attention must be
taken not to stain the optical surfaces with grease. the moveable mechanical parts
should be lubricated occasionally with a non-corrosive grease.
When not in use, remove the eyepieces and put them back into the lens box.
replace them with the eyepiece tube dust covers. the microscope should then be
secured in its box or covered with a dust cover.
