Care And Maintenance - Leica DM R Series Instructions Manual

Care and maintenance

Attention:
Disconnect from the mains before cleaning
and servicing!
Dust protection
Protect the microscope and peripherals from
dust by putting on the flexible dust cover after
each work session. Dust and loose particles of
dirt can be removed with a soft brush or lint-free
cotton cloth.
Solvents
Obstinate dirt can be removed with a clean
cotton cloth moistened with any ordinary
hydrous solution, benzine or alcohol. Do not use
acetone, xylol or nitro dilutions. Cleaning agents
of unknown composition should be tested on an
inconspicuous part of the microscope. Painted
or plastic surfaces must not be tarnished or
etched.
Acids, alkaline solutions
Particular care should be taken when working
with acids or other aggressive chemicals.
Always avoid direct contact between such
chemicals and the optics or stands. Thorough
cleaning after use is strongly recommended.
Keep the microscope optics absolutely clean.
Dust/optics
Remove any dust from glass surfaces with a
fine, dry, grease-free artists' hair brush, or by
blowing with a bellows ball or by vacuum
suction. Any remaining dirt can be removed with
a clean cloth moistened with distilled water.
Failing this, use pure alcohol, chloroform or
benzine.
Oil
First wipe off immersion oil with a clean cotton
cloth, then wipe over several times with ethyl
alcohol.
Attention: Fibre and dust residue can cause
disturbing background
fluorescence microscopy.
Objectives must not be opened for cleaning.
Only the front lens can be cleaned in the ways
described above and the upper lens by blowing
dust off with a bellows ball.
All Leica instruments are manufactured and
tested with extreme care. If you do have cause
for complaint, however, please do not try to
repair the instruments and their accessories
yourself. Contact your national agency or our
central servicing department, the Technical Ser-
vice in Wetzlar direct.
