ASSEMBLY AND OPERATING INSTRUCTIONS

To attach a quick connector

Prior to performing any assembly and/or adjustment procedures, make sure the air

supply hose (not included) is disconnected from the impact wrench.

1.Prior to use, the impact wrench requires the attachment of a quick-connector into

its air inlet. To do so, wrap approximately 3" of pipe thread sealer tape (not included)

around the male threads of a quick-connector. Then, firmly tighten the

quick-connector into the air inlet.

Loosening

1.Attach the correct size socket to the anvil.

2.Set the compressor's pressure regulator to 90 PSI. Do not set the compressor's

outlet regulator above 90PSI.

3.Connect the tool to the air compressor's hose. If leakage is detected, disconnect

the air hose and fix it correct before use.

4.Place the socket over the nut to loosen.

5.Grip the tool firmly. Press the REVERSE valve in from the area above the trigger

so that the REVERSE valve protrudes out the back of the housing. Press the trigger

to start the tool.

Caution:

Make sure the nut or bolt can withstand the impact wrench's working torque.

NOTE:

ØIf the tool cannot loosen the nut, DO NOT raise the outlet pressure of the air

compressor.

ØWhen the nut is moved, stop the tool by releasing the trigger and remove the tool

from the nut. Remove the nut from the socket if needed.

Tightening

The working torque of the impact wrench is 230 ft.-lbs. Make sure that the

nut or bolt you are using the tool to tighten can withstand the rated torque.

1.Tighten the nut as far as you can by hand.

2.Place the socket on the nut. Press the REVERSE valve forward so it protrudes

out the front of the Housing. Press the trigger to start the tool.
