WARNING
!
Use of plug is vital to your safety. If valve is accidentally
operated, velocity of unrestricted escaping gas is
forceful enough to cause injury, especially about the
face and head.
WARNING
!
Safety shipping cap must always be in place when
removing or installing a cylinder.
WARNING
!
Do not remove safety shipping cap to read gauge.
Read gauge through slots in shipping cap.
WARNING
!
Make certain safety plug is in place in cylinder valve outlet
before completing the following steps.
WARNING
!
Do not place body or head in front of cylinder valve outlet.
If valve is accidentally operated, velocity of unrestricted
escaping gas is forceful enough to cause injury, especially
about the face and head.
WARNING
!
Do not strike “pull” lever when connecting hose to cylinder
valve.
CAUTION
!
The Quick-Opening lever may be moved slightly
forward, approximately 1/4 inch (6.4 mm), to permit
