SILVER Line microscopes are designed to function with minimal maintenance, but certain
components should be cleaned frequently to ensure ease of viewing. The power switch
should be turned off or the microscope should be unplugged when not in use.
CLEANING
The front lens of the objectives (particularly the 40XRD and 100XRD) should be cleaned
after use. The lens surface may be gently cleaned with a soft camel hair brush, or blown 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 as this will scratch or otherwise mar the surface of the glass.
The finish of the microscope is hard epoxy and is resistant to acids and reagents. Clean this
surface with a damp cloth and mild detergent.
Periodically, the microscope should be disassembled, cleaned and lubricated. This should
only be done by a qualified, authorized microscope technician.
DUST COVER AND STORAGE
All microscopes should be protected from dust by a dust cover when in storage or not in use.
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 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.
TENSION CONTROL OF FOCUSING MOVEMENT
Tension of the focusing movement is controlled by a tension system found on the pinion of
the coarse focus control. This can be adjusted by using the wrench included with the
microscope.
