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
specified grease
Make sure there is no dirt on your
fingers or on the O-ring; then
squeeze about 5 mm of grease
onto your fingertip.
2
Spread the grease
over the O-ring.
Using two fingers and a thumb,
spread the grease over the O-ring
while rubbing it in. Use caution not to
squeeze or pull the O-ring too hard.
3
Check that there
is no damage or
irregularities on
the O-ring. Once the grease has permeated
throughout the O-ring, check it for damage
or irregularities (both visually and by
touch). If you notice any abnormalities,
replace the O-ring with a new one.
4
Apply the grease
to the O-ring
contact surface. Use any residual grease on your
fingertips to clean and lubricate the O-
ring contact surface on the front lid.
