Immediately after removing high pressure hose from N2 cylinder outlet, make certain safety plug is put in place in outlet. If valve is accidentally operated, velocity of unrestricted escaping gas is forceful enough to cause injury,
especially about the face and head.
The quick-opening lever may be moved slightly forward, approximately 1/4in. (6.4mm). Forward movement in excess of 1/4in. (6.4mm) may result in actuation of the valve.
