How to apply grease to the O-ring
1 Apply only Olympus
exclusive lubricant to each
O-ring.
2 Spread the lubricant onto
the entire circumference of
the O-ring.
3 Check that the O-ring is free
of scratches or unevenness.
• 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.

Install the O-ring
Confirm that no foreign matter is in the gap and then fit the O-ring. At this time, confirm that the O-ring
does not stick out from the groove.
When sealing this product, make sure that no hairs, fibers, sand particles or other foreign matter stick
not only to the O-ring, but also to the contact surface (front cover). Even a single hair or a single grain of
sand may cause water leakage. Please check with special care.

Examples of foreign matter sticking to the O-ring
Hair
Make sure that your fingers and the O-ring are
free of dirt, then squeeze the appropriate
amount of exclusive lubricant onto a finger to
spread onto the entire circumference of the O-
ring (approx. 15 mm is adequate).
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 lubricant, 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.
