Q9 : What are the important points for O-ring maintenance?
A9 : Please observe the following items.
(1) Never use alcohol, thinner, benzene or similar organic solvents or
chemical detergents to clean the O-ring. When such chemicals are used,
it is to be feared that the O-ring will be damaged or that its deterioration
will be accelerated.
(2) Use the original Olympus silicone O-ring grease (white cap). The grease
attached to Cases up to PT-008 (red cap) and the grease of other
companies are not suitable for this silicone O-ring, and use of such
grease may cause deterioration of the surface and impairment of the
waterproof function.
(3) In order to avoid deformation of the O-ring when the Case is not used for
a long time, remove the O-ring from the Case, apply a thin coat of the
special grease, and store the O-ring in a clean plastic bag. For reuse,
confirm that the O-ring is free of damage and cracks, that it has sufficient
elasticity, that the surface is free of stickiness and other abnormalities,
and use it after applying a thin coat of the special grease. Excessive
application of grease does not improve the waterproof function or the
permissible withstand pressure. However, it may facilitate attachment of
sand, dirt, etc.
A thin, uniform coat produces the best result.
(4) The O-ring is a consumable product. Replace it at least once a year.
(5) Deterioration of the O-ring is accelerated by the use conditions and the
storage conditions. Replace the O-ring immediately by a new one if it
shows signs of damage, cracking or loss of elasticity.
Q10: What are the important points for Case maintenance?
A10: Please observe the following items.
(1) Never use the following chemicals for cleaning, corrosion protection,
defogging, repair or other purposes.
• Never use alcohol, thinner, benzene or similar volatile organic solvents
or chemical detergents to clean the Case. Pure water or lukewarm water
is sufficient for cleaning.
• Do not use anticorrosion agents on the metal parts. The metal parts are
made of aluminum, brass or stainless steel. Cleaning with pure water is
sufficient.
• Do not use commercial defogging agents. Always use the original
Olympus defogging silica gel.
• Do not use adhesive for repairs or other purposes. When repair is
required, please contact a service station of our company or your dealer.
