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.
