PreparationAcceptable Base MaterialsPowder actuated fastening is suitable foruse in the following base materials only:• Poured Concrete• Structural Steel• Masonry Joints (see page 8)Never attempt to fasten into any othertype of material. Fastening into othermaterials can cause blindness or otherserious injury.Unacceptable Base MaterialsNever attempt to fasten into very hard orbrittle materials such as cast iron, tile,glass, or rock of any type. These materialscan shatter, causing the fastener and/or basematerial fragments to fly free and causeserious injury to the tool operator and others.Never fasten into soft base materials, such asdrywall or lumber products. These materialsmay allow the fastener to travel completelythrough and out the other side, endangeringthose in the path of the fastener.Never fasten into any base material thatdoes not pass the Center Punch test.Failure to assure the suitability of the basematerial can result in serious injury to theeyes or other body parts.Center Punch TestALWAYS WEAR SAFETY GOGGLESWHEN PERFORMING THIS TEST.1. Always check the material beingfastened into for hardness beforeattempting any fastening operation.2. Using a fastener as a center punch,strike the fastener against the worksurface using an average hammerblow and check the results.Center Punch Test Results1. If the fastener point is flattened,the material is too hard for apowder actuated fastening.2. If the fastener penetrates thematerial easily, the material istoo soft.3. If the material cracks or shatters,the material is too brittle.4. If the fastener makes a smallindentation into the material, thematerial is suitable for fastening.DANGER SAFETY INSTRUCTIONSSAFETY INSTRUCTIONSDANGER 3NEVER FASTEN INTO VERY HARD ORBRITTLE MATERIALSNEVER FASTEN INTO SOFT MATERIALSSUCH AS DRYWALLPMLaam•••NomoMNmcpslelhNbopleqdNbddgPUC12
