5INSTALLATION & OPERATING INSTRUCTIONSSafety requirements: The use of a safety guard is recommended toprevent operator injury. Rapid-Air manufactures safety guardsfor all Rapid-Air model air feeds. When using an electric valve,a safety switch is recommended for the operator to disconnectpower when servicing equipment. The use of a 3 way shut-offvalve is required to be installed at the feed so the operator canshut off air and purge the feed of air before servicing the feedor press. A 2 way valve is not sufficient as it will only shut off airand not release the air in the feed. A quick disconnect couplingshould also be used behind the shut-off valve for easy removalof the feed from the press. Make certain the slide block is forward(at main body) before turning air on. If an electric valve or anelectrical circuit is used on or with the feed, it must be wiredthrough the safety disconnects of the press it is used on. Thefeed should always be controlled by the press.STEPACTUATINGVALVESTATUSSTOCKCLAMPSTATUSFEEDCLAMPSTATUSSLIDEBLOCKSTATUS12345STARTSDOWNDOWNDOWNSTARTSUPUPCLOSESCLOSEDCLOSEDCLOSEDOPENCLOSEDOPENOPENCLOSESCLOSEDFORWARDSTARTSRETRACTINGRETRACTEDRETRACTEDFEEDING*** TEMPORARILYAIR FEED OPERATING SEQUENCE STEP 1STEP 2STEP 3STEP 4STEP 5
