OPERATION

NOTE: Turn off your air compressor and disconnect the air pressure hose before changing sockets or making any adjustments to this tool. Severe injury or property damage may result otherwise.

WARNING: This tool generates considerable torque when in use. Always hold the tool with both hands when using, and brace yourself to resist the torque which will be delivered to the work piece.

1.Select the appropriate size 1” square drive socket (not included) for your needs. Push and snap the socket onto the Anvil (13).

NOTE: On this tool the designation “R” refers to forward or clockwise rotation. “L” refers to reverse or counterclockwise rotation. Always be aware of the direction of the threading of the fasteners you are working on. While most fasteners install with clockwise rotation, some threads are intentionally the reverse.

2.Set the directions of the Air Impact Wrench to Forward (R=right or clockwise) or Reverse (L=left or counterclockwise) by adjusting the Rotation/Torque Knob (38). You may control the amount of torque to be applied by selecting any of the 3 torque settings (1=low, 2=medium, 3=high).

NOTE: The actual torque delivered at each of the 3 torque settings will depend on the air pressure supplied to the tool. We suggest that you test the actual torque by tightening a nut or bolt at each setting, then observing the resultant torque by using a mechanical torque wrench (not supplied).

3.If installing a nut or bolt, set it as tight as possible by hand.

4.Place and push on a appropriate size impact socket onto Anvil (13) and place the Impact Socket (not included) over the fastener.

5.Grip the Air Impact Wrench tightly with both hands, and squeeze the Trigger (36). The tool will operate and tighten the fastener.
