to dislodge any dust or dirt that may be present in the valve.
CaUtion
Open the cylinder valve slightly. If you open the valve too much,
the cylinder could tip over. When cracking the cylinder valve, Do
not stand directly in front of the cylinder valve. Always perform
cracking in a well-ventilated area. If an acetylene cylinder sprays
a mist when cracked, let it stand for 15 minutes. Then, try to
crack the cylinder valve again. If this problem persists, contact
your gas supplier.
