2. Place the valve protection cap on the cylinder whenever mov ing
it, placing it in storage, or not using it. Never drag or roll cylinders
in any way. Use a suitable hand truck to move cylin ders.
3. Store empty cylinders away from full cylinders. Mark them
“EMPTY” and close the cylinder valve.
4. NEVER use compressed gas cylinders without a pressure
reducing regulator attached to the cylinder valve.
5. Inspect the cylinder valve for oil, grease, and damaged parts.
WARNING
DO NOT use the cylinder if you find oil, grease or
damaged parts. Inform your gas supplier of this condition
immediately.
6. Momentarily open and close (called “cracking”) the cylinder valve
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.
