Position the CPA wrench over the nut so the outer socket makes contact with the washer and the wrench inner socket fits directly over the spline.

After pressing the power trigger the outer socket begins to rotate the nut clockwise until the correct bolt tension is reached.

After correct tension is achieved the inner socket rotates counter clockwise to shear the spline from the CPA bolt assembly.

Remove the outer socket from the nut engaging the wrench ejector to discard the used spline.
