Note on the O-ring (continued)
Handling the O-ring
Set the O-ring in place
Avoid setting the O-ring in dusty or sandy locations.
1 Remove the O-ring.
Do not use pointed or metal objects to remove the O-ring. These objects might
scratch or damage the marine pack groove or O-ring.
2 Inspect the O-ring.
•Fully check the following, and wipe off with a soft cloth or tissue paper.
– Check for any dirt, grains of sand, hair, dust, salt, thread scraps, etc.
– Check for any old grease.
•Lightly run your fingertip around the O-ring to check for any unapparent
dirt.
•After wiping the O-ring, take care to prevent any cloth or tissue paper fibres
from remaining on the O-ring.
•Check the O-ring for cracking, skew, distortion, fine splitting, scratches,
sand-biting, etc. Replace cracked or scratched O-rings.
3 Inspect the O-ring groove.
Grains of sand or hardened salt sometimes get into the groove. Carefully remove
them by blowing with an air spray or by wiping them with a cotton wool bud.
Prevent fibre scraps from the cotton wool bud from entering inside.
4 Also, inspect the contacting surface on the other side of the O-ring in the same
way.
