Note: On the bottom of the Forward/Reverse Valve (34) there are markings on the valve that show what direction the Forward/Reverse Valve (34) is set to. If the bottom valve is turned in the “Off” arrow’s direction, then the Impact Wrench is set to take off bolts. If the bot- tom valve is turned in the “On” arrow’s direction, then the Forward/ Reverse Valve (34) is set to tighten on bolts.

Note: Set the Forward/Reverse Valve (34) so that the anvil turns clockwise (forward).

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

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

6.Grip the Impact Wrench firmly with two hands and gently squeeze the Trigger (21).

Note: If the Impact Wrench cannot tighten the nut to your satisfaction, do not raise the air pressure on the compressor over 120 PSI. Pressures above 120 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.

7.When the nut is tightened, release the Trigger (21). Turn off the air compressor and disconnect the hose.

8.Always 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.
