Install the O-ring.
Confirm that no foreign matter is attached, apply a thin coat of the
accessory grease to the O-ring, and fit the O-ring into the groove. At
this time, confirm that the O-ring does not stick out from the groove.
:
• When a mechanical pencil or a similar other sharp
object is used to remove the O-ring or to clean the
inside of the O-ring groove, the Case and the O-ring
may be damaged and water leakage may be caused.
• When the O-ring is checked with the fingertips, take
care not to stretch the O-ring.
• Never use alcohol, thinner, benzene or similar solvents
or chemicals detergents to clean the O-ring. When such
chemicals are used, it is likely that the O-ring will be
damaged or that its deterioration will be accelerated.
CAUTION
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.
Surround the lubricant with three
fingers and spread it over the ring. Be
careful not to use excessive force as
this may stretch the O-ring.
3
Check that the
O-ring is free of
scratch 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, 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.
