How to Apply Grease to the O-ring
1
Apply the exclusive
lubricant to the O-ring.
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).
2
Spread the lubricant
all over the O-ring.
Apply the lubricant with 3 fingers and
spread it over the O-ring. Be careful not
to use force as this may stretch the O-
ring.
3
Check that the O-ring
is free of scratches or
unevenness.
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, be sure to
replace it with a brand-new O-ring.
CAUTION:
• Always perform maintenance of the waterproof function even when the
Case has been opened every shooting. Neglecting this maintenance may
cause 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.
Examples of foreign matter sticking to the O-ring
Hair
Fibers
Grains of sand
