Operation (continued)

Note: Turn off your air compressor and disconnect the air hose when you are changing sock-

ets.  After you attach the socket, attach the air hose and turn the air compressor on.

4.

Select the appropriate size 3/8” drive socket for your needs.

5.

Push and snap the socket (not included) onto the Anvil (31).

6.

To operate the Regulator Knob (12), follow the directions in FIGURE 2 on page 6.

Note: Set the Reverse Valve (9) so that the anvil turns clockwise (forward) - see FIGURE 3 on

page 6.

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 (14).

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 (14).  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.

Loosening

Note: Set the Reverse Valve (9) so that the anvil turns counterclockwise (reverse).

12.

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

13.

Grip the Impact Wrench firmly with two hands and gently squeeze the Trigger (14).

Note: If the Impact Wrench cannot loosen the nut, do not raise the air pressure on the com-

pressor over 90 PSI.  Do not attempt to loosen the nut with the Impact Wrench. Use
other appropriate methods and tools to loosen the nut.

14.

When the nut is loosened, release the Trigger (14).  Turn off the air compressor and
disconnect the hose.

15.

If needed, remove the nut from the socket.

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

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.
