2 Check the O-ring.

•

Check that there is no dirt, sand, hair, dust, salt crystals, lint or grease on

the O-ring. If you find any of these, remove them with a soft, dry cloth.

• There may be dirt on the O-ring that you cannot see. Check if there is any

dirt by rubbing your finger over the O-ring.

• Be careful not to leave any fibers from the dry cloth on the O-ring when

wiping it.

• Check that the O-ring is not ripped, twisted, squashed, frayed or scratched

and that there is no sand sticking to it. Replace the O-ring in these cases.

3 Inspect the O-ring groove.

•

Grains of sand or hardened salt crystals may get into the O-ring groove.

Remove them carefully with an air spray or a cotton swab. If you use a

cotton swab, be careful not to leave any fibers from it in the O-ring groove.

• Inspect the front case groove as well as the rear case (side where O-ring

is set) groove.
