WARNING DO NOT OVER-INFLATE OR UNDER-INFLATE A
PNEUMATIC PLUG! OVER-INFLATION of a pneumatic plug (exceeding
the required ination pressure) may cause the plug to rupture and
dislodge at extreme velocity! UNDER-INFLATION of a pneumatic plug
(ination to pressure less than that required) may cause the plug and the
media restrained to dislodge from the pipe! A plug that is over-inated
or under-inated may not fail immediately. However such failure may
occur at any time without warning! IMPROPER INFLATION MAY CAUSE
PLUG FAILURE OR DISLODGEMENT WHICH MAY RESULT IN DEATH,
SERIOUS BODILY INJURY AND/OR PROPERTY DAMAGE!
