Refer to FIGURES 1 and 2 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 impact socket for your needs.
5. Push and snap the socket (not included) onto the Anvil (33).
6. Note: As shown on FIGURE 2 on page 6, there are two Valve Knobs (3), one for For-
ward and one for Reverse.
7. Tighten the nut as tight as you can by hand.
8. Place the socket (not included) over the nut you wish to tighten.
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.
9. Grip the Impact Wrench firmly with two hands and gently squeeze the Trigger (11).
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
workpiece 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 (11). 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.

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