If work is interrupted for any reason, remove the power load strip before removing the power fastener.
12 105635 Why A Power Fastener Holds WHY A POWER FASTENER HOLDS IN CONCRETE The compression bond of the concrete to the power fastener accounts for the majority of the holding power. The fastener displaces the concrete which tries to return to its original form causing a squeezing effect.
13 105635 482-67 OVERDRIVE G 018 Selecting Power Fasteners and Power loads FASTENING INTO CONCRETE The proper power fastener length can be determined by adding the thickness of the material to be fastened and the amount of fastener that will actually penetrate the con- crete.
14 105635 Operation 1. Grasp barrel assembly and slide forward rapidly until it stops. Push barrel assembly back into tool to the closed position. This sets piston into firing position. 4. Place the muzzle of tool perpendicular to work surface without tilting the tool.
15 105635 Operation 5. Squeeze trigger to set power fastener. Be sure to keep pressure on tool during this operation. 7. Should the tool fail to fire, hold the muzzle firmly against the work surface for 30 seconds. Release the trigger and remove pressure on the tool while holding the muzzle against the work surface.
