Carefully observe the O-ring maintenance manual for the handling of O-rings
before use.
The silicon grease included in the product package is inedible.

E-4
Precautions on Handling the O-ring
CAUTION
Are there any scratches or cracks in the O-ring?
Be careful about dust, sand, and hair
SEA&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.
For 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.
If 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.
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.
This product 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.

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.
Precautions on Handling the O-ring
Coat with silicone grease
Do not twist the O-ring
Remove the O-ring for inspection before each use
Be careful about how you store O-rings
O-rings last for one year
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.
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.
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.
