How to Apply Grease to the O-ring
1
Apply the exclusive
lubricant to each
O-ring.
Make sure that your fingers and the
O-ring are free of dirt, and squeeze about
5 mm of lubricant onto a finger. (5 mm is
the most appropriate amount.)
2
Spread the lubricant
all over the O-ring.
Apply the lubricant with three fingers and
spread it over the 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.
4
Apply lubricant on the
O-ring contact
surface.
Use the lubricant remaining on the
fingers to clean and lubricate the case’s
contact surface.
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.
