CLEANING - the front lens of the objectives (particularly the 40xRD and 100xRD) should be cleaned as often as possible due their longer length - coming into contact with the slide. First, brush with a soft, camel hair brush or blow off with air pressure from a rubber syringe to remove dust particles. Then, wipe gently in circular motion with a soft lens tissue moistened with lens cleaning solution or distilled water, and dry immediately in circular motion 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 repair technician or send to New York Microscope Company for service/repair.
The eyepiece(s) should be cleaned with optical cleaning solution in the same manner as the objectives. Lenses should never be wiped while dry as this will surely scratch or otherwise mar the surface of the glass.
The finish of the microscope varies including hard epoxy and is resistant to acids and reagents. Clean this surface with a damp cloth and mild detergent.
Maintenance: Periodically, the microscope should be disassembled, cleaned, adjusted and lubricated. Sometimes optically alignments and or mechanical repair/overhaul is required to focusing mechanism, mechanical stage or interpupliary distance tubes, electrical, etc. This should be preformed only by a qualified, authorized microscope repair technician or send to New York Microscope Company for service/repair.
DUST COVER AND STORAGE - All microscopes should be protected from dust by a dust cover when not in use or in storage. A dust cover is the most cost-effective microscope insurance you can buy. Ensure that the storage space is tall enough to allow the microscope to be placed into the cabinet or onto a shelf without making undue contact with the eyepieces. Never store microscopes in cabinets containing chemicals, which may corrode your microscope. Also, be sure that the objectives are placed in the lowest possible position/magnification (ie. 4x) and the rotating head is turned inward and not protruding from the base. Microscopes with mechanical stages should be adjusted toward the center of the stage to prevent the moveable arms of the mechanical stage from being damaged during storage in the cabinet.
