The grease protects the O-ring and gasket from wear.
After checking that there are no cracks or dust on the O-ring
and gasket, grease them using a finger. During greasing,
recheck that there are no cracks or dust.
Never use cloth or paper for greasing because the fibers may
cling.

them.

Do not:trap the O-ring and waterproof gasket with
the marine pack.
When jointing the marine pack, be careful not to trap the O-
ring or gasket between the front and rear bodies. If this
happens, not only will the O-ring or gasket be damaged, but
also water may leak in.

cool place, packed in the original carton. Be sure to avoid the
following:
