CHERNE Test-Ball - 14 Clean and Inspect Plug after Every Use and Store Properly

14. CLEAN AND INSPECT PLUG AFTER EVERY USE AND
STORE PROPERLY.
A. CLEAN AND INSPECT PLUG as outlined in Section 5 of this manual.
B. STORE THE PLUG IN A CLEAN DRY PLACE,
away from sunlight or
other sources of ultra-violet light and away from sources of ozone, such as
electrical equipment. Ozone and ultra-violet light may cause the elastomer
(rubber) to weaken and fail prematurely.
C. STORE PLUGS BELOW 110 DEGREES F
(43 degrees C). Exposure to
excessive temperatures may cause damage to the elastomer of pneumatic
plugs. NOTE: Storage of plugs in non-ventilated structures (such as metal
buildings) may expose the plugs to excessive temperatures which may
damage the plugs and possibly result in a plug failure.
D. ARMOR ALL® MAY BE USED AS A PRESERVATIVE
on elastomeric
(rubber) surfaces for extended storage. Apply only a light coating to the
plug. Other water or silicone based preservatives may also be used (see
warning below). (ARMOR ALL® is a Registered Trademark of Armor All
Products Corp. Allso Vlejo, CA. USA 92656)
E. PLUGS MAY BE STORED SUSPENDED VERTICALLY OR PLACED
HORIZONTALLY.
When storing a plug, it is recommended that the plug
be partially inated to 1 PSIG only (see ination warning below), which will
prevent a permanent crease from forming in the plug body. A crease may
cause a weakened area resulting in premature failure upon plug ination
or use.
WARNING DO NOT INFLATE PLUG IN EXCESS OF ONE (1)
PSIG WHEN PLUG IS NOT IN A PIPE! Plugs are designed only to be fully
inated when properly positioned inside a pipe. THE PLUG MAY RUPTURE
RESULTING IN DEATH, SERIOUS BODILY INJURY AND/OR PROPERTY
DAMAGE!
WARNING EXCESSIVE COATING OF PRESERVATIVE ON
ELASTOMER MAY RESULT IN A SLIPPERY PLUG SURFACE AND
REDUCE THE BACK PRESSURE HOLDING CAPABILITIES! DO NOT
COAT A PLUG IMMEDIATELY BEFORE USE AS THE COATING MAY
REDUCE THE BACK PRESSURE HOLDING CAPABILITIES OF THE
PLUG. If plug use is required and the plug has an excessive coating of
preservative, the plug should be washed with solution of water and mild
detergent, ushed with clean water and then allowed to air dry before use.
USE OF SOME PRODUCTS SUCH AS PETROLEUM OR SOLVENT
BASED COMPOUNDS MAY CAUSE SEVERE DAMAGE TO THE PLUG!
The damage may be below the plug surface and not be obvious during
inspection but failure may result upon plug ination or use. PLUG FAILURE
MAY RESULT IN DEATH, SERIOUS BODILY INJURY AND/OR PROPERTY
DAMAGE!
