Collet Nut Insertion Procedure:
1. Insert the collet at an angle, fitting the two extractor teeth which protrude A (figure 1) into the collet's groove (figure 2).
2. Place the two parts on a clean and horizontal work surface, press down with your thumb on the back end of the collet until it clicks into place (figure 3).

Extraction Procedure
1. Place the nut on your right hand, push the top of the collet with a middle finger towards the mark on a nut, to let A site of the nut completely insert the collet groove (figure 4). At the same time, the left hand tightly holds the nut, the thumb pulls the bottom of the collet at the mark direction (figure 5), to make one side of the collet out of the nut (figure 6).
2. Slightly rotating collet to remove it from the nut.
3. Please use a screwdriver instead if necessary (figure 7).
