OPERATING INSTRUCTIONS

WARNINGS

Do not use a commercial air cylinder if its markings are missing or defaced. Do not tamper with

safety devices in commercial air cylinder valves.

Keep commercial air cylinder valves closed when the cylinder is hot in use.

Use only authorized gages, regulators, hose, pipe, and tubing on commercial air cylinders high-

pressure spheres, and pressure tanks. DO NQT IMPROVISE.

Before removing the manifold machine plug-on the MlA1 compressor, see that the manifold

bleeder valve of the section in use is open. Insure that no pressure is indicated on the manifold

pressure gage (2, fig. 11) in that section.

Do not drop commercial air cylinders, high-pressure spheres, or pressure tanks. Handle them

with care and store them away from heat.

Use ONLY COMPRESSED AIR when charging commercial air cylinders, high-pressure spheres, or

pressure tanks.

Keep protection caps on commercial air cylinder valves when the cylinder is not in use.

Do not attempt to alter or repair a commercial air cylinder.

Do not use any compressed air handling unit, component, or device that is internally

contaminated with grease, oil, or flame fuel. If grease, oil, or flame fuel is detected in commercial

air cylinders, high-pressure spheres, pressure tanks, valve assemblies, connections, or hose,

clean parts with an approved cleaning solvent (Type I, regular, Federal Specification O-T-620) and

dry before using.

Be sure that there are no personnel in front of an open valve.

Always open valves slowly.

Always secure commercial air cylinders to prevent them from falling, rolling, or moving
