Applying Grease To The O-Ring; Replace Consumable Products - Olympus PT-EP10 Instruction Manual

Applying grease to the O-ring

1 Apply only Olympus
exclusive grease to O-ring.
2 Spread the grease onto the
entire circumference of the
O-ring.
3 Check that the O-ring is free
of scratches or unevenness.
CAUTION:
• Always perform maintenance of the waterproof function even when the Case has been opened every
shooting. Neglecting this maintenance may become the cause of water leakage.
• When the Case is not to be used for a long time, remove the O-ring from the groove to prevent deformation
of the O-ring, apply a thin coat of silicone grease, and store it in a clean plastic bag or the like.

Replace consumable products

• The O-ring is a consumable product. Independent of the number of times the Case is used, it is
recommended that the O-ring should be replaced by a new piece at least once a year.
• Deterioration of the O-ring is accelerated by the usage conditions and the storage conditions. Replace
the O-ring even before a year has passed if it shows signs of damage, cracking or loss of elasticity.
CAUTION:
• Use genuine Olympus silicone grease, silica gel and O-ring.
• Do not try to replace the O-ring by yourself.
• We recommend to perform the check periodically.

Examples of foreign matter sticking to the O-ring
Hair
Make sure that your fingers and the O-ring are
free of dirt, and squeeze about 5 mm of grease
onto a finger. (5 mm is the most appropriate
amount.)
Spread the grease onto the entire
circumference of the O-ring using 3 fingers.
Be careful not to use excessive force as this
may stretch the O-ring.
After spreading the grease, check visually and
by touch that the O-ring is not scratched and
that its surface is flat. If it is damaged in any
way, replace it with a brand-new O-ring.
