OPERATION
WARNING! This tool generates considerable torque when in
use. Always hold the tool with both hands when using, and
brace yourself to resist the torque which will be delivered to
the workpiece.
1. Tighten the nut as far as you can by hand before using the
impact wrench.
2. Connect the impact wrench to the air hose.
3. Place the socket over the fastener, grip the impact wrench
firmly with both hands and gently squeeze the trigger. The
impact wrench will activate when the trigger is squeezed.
3.1 If the tool stalls while tightening, do not raise the
output pressure of the air compressor above 90 PSI.
Pressure above 90 PSI will strip the workpiece and
damage the tool, potentially causing tool failure and
serious injury. Use other appropriate methods and
tools to tighten the nut.
4. This tool will stop operation/rotation a few seconds after
the trigger is released.
5. When the fastener is tightened, release the trigger and
remove the tool and socket.
6. Use a mechanical torque wrench to check the
fastener torque.
7. Reversing the rotation direction is accomplished by
releasing the reverse button above the trigger. To reset the
rotation to forward, press the reverse button until it is
seated against the handle. Clockwise is forward.
7.1 Wait until the tool’s shaft has stopped rotating before
switching to the opposite direction.
8. When finished with the tool, turn off the air compressor,
disconnect the air hose and discharge any residual air
remaining in the tool. Put the impact wrench away in a safe
storage area.
