zCarefully observe the O-ring maintenance manual for the handling of O-rings before
use.

E-4
This model is kept watertight by the O-ring. To keep the O-ring functioning
properly, please observe the following. Improper handling of the O-ring could
cause flooding.
Check the O-ring to make sure there are no
scratches or cracks. If there are, replace the O-ring
with a new one immediately. When handling the O-
ring, do not use pointed metal objects, which could
damage the O-ring. Use of the included O-ring
remover is recommended.
Check the O-ring to make sure that there is no dust, sand, or hair on the O-ring,
in the O-ring’s grooves, or on the O-ring’s contact surfaces. If any of these things
are attached, remove them completely. If used as is, these things could cause
flooding.
Precautions on Handling the O-ring
CAUTION
zSEA&SEA products use blue O-rings. These O-rings are impregnated with
silicone oil through a special process. The lubricating effect of the O-ring lasts
as long as the silicone oil is gradually seeping out from within.
zFor the maintenance of these blue O-rings, make sure to use genuine
SEA&SEA silicone grease (O-ring grease for use with the blue O-rings that
comes in tubes with blue lettering and blue caps). If you use silicone grease
from other companies or SEA&SEA’s own silicone grease that comes in tubes
with black lettering and black caps, the grease you apply will be sucked into the
blue O-rings due to their special characteristics, which will result in insufficient
grease. If this happens even once, the O-ring will not revert to its normal state
and must be replaced.
zIf the grease is insufficient, the O-ring will not slide, and it will become harder
to open and close the waterproof parts. Because of this, it could become
impossible to open or close the housing or it could cause flooding, so please
refrain from using the housing with insufficient grease.
Are there any scratches or cracks in the O-ring?
Be careful about dust, sand, and hair
O-ring remover

Precautions on Handling the O-ring
E-5
Silicone grease protects the O-ring from chafing.
After checking the O-ring to make sure that there
are no scratches, dust, or debris, apply a light
coating of silicone grease to the entire O-ring with
your finger. Applying too much grease will make
it easier for dust and debris to adhere to the O-
ring, and could cause flooding.
When fitting the O-ring into the O-ring groove,
insert it straight into the groove; do not bend or
twist it.
In principle, the O-ring should be removed before each use so that the O-ring, O-
ring groove, and O-ring contact surfaces can be checked. This is because you
cannot find any sand or debris that may have gotten into the O-ring groove if the
O-ring is not removed. For routine maintenance prior to each use, it is advisable
to make sure to remove the O-ring.
When storing spare O-rings or O-rings that you have removed from the housing,
keep them in a cool place out of direct sunlight. Also, when storing O-rings, do
not place heavy objects on them or twist them.
Although it depends on how well they are maintained, how often they are used,
and how they are stored, O-rings generally last for one year. It is advisable to
inspect them before use, and replace them early.
