Bi-directional quick change tool-less lever and wedge actuated collet chuck, system and/or method for using the same

A method of operating a rotary power tool, comprising:

• allowing a first inward surface of a first lever to move inwardly toward an axis defined by a collet by moving a wedge located inwardly of and contacting the first inward surface in a first direction;
• allowing a second inward surface of the first lever to move away from the axis by movement of the wedge in the first direction;
• inserting a shank of an accessory into the collet after the second inward surface has moved away from the axis;
• forcing the first inward surface away from the axis by moving the wedge in a second direction opposite to the first direction;
• forcing the second inward surface toward the axis by moving the wedge in the second direction;
• forcing a first portion of the collet against the shank by forcing the second inward surface toward the axis;
• and
• rotating the collet with the second inward surface forced toward the axis.
