Q5: What are the important points for O-ring maintenance?
A5: 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 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 flash is not used
for a long time, remove the O-ring from the flash, 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 maximum level of 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.
Q6: What are the important points for the flash maintenance?
A6: Please observe the following items. Never use the following
chemicals for cleaning, corrosion protection, repair or other
purposes:
• Never use alcohol, thinner, benzene or similar volatile organic
solvents or chemical detergents to clean the flash. 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 adhesive for repairs or other purposes. When repair
is required, please contact your local service station or dealer.
