Note on the O-ring (continued)

Maintenance

After you have finished using an O-ring
• After you have used the marine pack, be sure to perform the following:
– Wash the marine pack with fresh water with the buckle closed to remove salt or
– Insert the marine pack in fresh water for about 30 minutes with the buckle closed.
– When sun oil is stuck to the marine pack, wash off with lukewarm water.
– Wipe the inside of the marine pack with a soft, dry cloth. Do not wash with water.
• Remove the O-ring each time that you have finished using it, and check it.
If the marine pack is dried with sea water still in the O-ring groove, salt crystals form,
and might impair the O-ring's functions.
• Do not use thinner, benzene, alcohol or other solvents as they will damage the
surface finish.
Storing O-rings
• Prevent dust from sticking to O-rings.
• Apply a thin coating of grease to the O-ring, set it in the groove, and store in a well-
ventilated location. Do not close the buckle.
• Avoid storing O-rings in hot, cold or humid locations, and placing in naphthalene or
camphor. These locations and solutions will damage the materials.
How to store O-rings
• To maintain the O-ring's functions, avoid storing them in hot locations or in the
direct sunlight.
• Do not place the spare O-ring under heavy objects. Doing so might deform the
O-ring.
O-ring life
Replace the O-ring with a new one after one year of use.

waterproof qualities of the O-ring. Replace the O-ring with a new one if cracking, skew,
distortion, fine splitting, scratches, sand-biting, etc. is found.
