It is important to be safe when installing quick disconnect couplings into a pneumatic
circuit. Never install a pneumatic coupling directly into an air tool, use a piece of hose
that is at least 18" long, between the tool and the coupling, to prevent damage to the
coupling. To protect the operator, safety devices, such as a safety check valve and safety cable
should be installed in case there is a hose or coupling failure. For safety cables and check
valves see pages 362 and 556.
