PRINCIPLES OF OPERATION.
a. Raising handle (6) drives the
nitrogen cylinder (3) downward pressing the
outer neck surface through an O-ring to form an
air-tight seal. When the handle contacts the
nitrogen cylinder, the handle locking pin (8)
pops out to lock the nitrogen cylinder. At the
same time, the end of nitrogen cylinder (3) is
pressed onto the piercing pin assembly (9).
When piercing pin enters the nitrogen cylinder
seal, compressed nitrogen is released into the
