Operation (continued)

Warning!! This Impact Wrench supplies powerful torque and is designed to be operated with two hands. Failure to operate the Impact Wrench with two hands may result in serious injury.

Refer to FIGURES 1 through 3 on page 6, and the Assembly Drawing on page 8.

Note: Turn off your air compressor and disconnect the air hose when you are changing sockets. After you attach the socket, attach the air hose and turn the air compressor on.

4.Select the appropriate size 1/2” drive socket for your needs.

5.Push and snap the socket (not included) onto the Anvil (105).

6.To operate the Forward/Reverse Lever (205) follow the directions in FIGURE 2 on page 6.

Note: Set the Forward/Reverse Lever (205) so that the anvil turns clockwise (forward).

7.Tighten the nut as tight as you can by hand.

8.Place the socket (not included) over the nut you wish to tighten.

9.Grip the Impact Wrench firmly with two hands and gently squeeze the Trigger (409).

Note: If the Impact Wrench cannot tighten the nut to your satisfaction, do not raise the air pressure on the compressor over 90 PSI. Pressures above 90 PSI will strip the work- piece and damage the tool, potentially causing the tool to fail, causing serious injury. Use other appropriate methods and tools to tighten the nut.

10.When the nut is tightened, release the Trigger (409). Turn off the air compressor and disconnect the hose.

11.If available, check the recommended torque specification for the nut. Use a torque wrench to tighten the nut to the proper setting after using the Impact Wrench.
