IMPORTANT SAFETY PRECAUTIONS TO REMEMBER
• ALWAYS have fire extinguisher accessible.
• Never use oxygen or fuel gas to blow soot or dirt from your clothes.
Do not wear torn or ragged clothes; Sparks can ignite the ragged ends.
• Always use goggles or helmet with proper lens with shade.
• Do not use shaded safety spectacles or face shield visors for cutting or
welding. They do not meet the requirements to prevent harmful rays from
damaging your eyes.
• Use gauntlet type gloves made of heat-resistant leather asbestos
or asbestos substitute.
• Secure cylinders to cart, wall or post to prevent them from falling.
• All cylinders should be used and stored in an upright position.
• Never drop or strike a cylinder. Do not use cylinders that have been dented.
• Cylinder caps should be used when storing or moving cylinders.
• Empty cylinders should be kept in specified areas and clearly marked “Empty”.
• NEVER use oil or grease on any inlet connections,
outlet connections or cylinder valves.
• Examine hoses for cuts, burns, or worn areas before each use.
Also inspect fittings for damage. If any damaged areas are found,
replace immediately.
• Do not repair hose with friction tape.
• ALWAYS use reverse-flow check valves on torch and regulator.
This greatly reduces the possibility of mixing gases in the regulator or
hoses. Reverse-flow check valves is an important safety precaution.
• Working pressure on acetylene regulator should NEVER be set above 15psi.

4. Regulator adjusting screws should be turned counter-clockwise to relieve
pressure on diaphragm before opening cylinder valves. (Fig. 3)
If this is not done, pressure from cylinder can damage diaphragm
and render regulator inoperable.

SET UP AND OPERATION GUIDE
1. Secure cylinder. (As noted in safety precautions.)
2. While standing to one side, “crack” each cylinder valve. (Fig.1) “Cracking” is to
quickly open and close the valve, allowing gas to escape and clearing the valve
of any foreign material.
CAUTION:
If oil or grease is found, discontinue use of cylinder immediately
and contact your supplier.
FIG. 1
3. Attach regulators to proper cylinders. A wrench should be used to ensure tight
connections. (Fig. 2) Make sure they are tightened in correct directions.
(Normally it is clockwise for Oxygen and counterclockwise for Acetylene.)
