The post driver machine includes a housing, inside of which is a weight which can be lifted by a chain being rotated around a generally elliptical path by a powered sprocket. A method of producing same has a step of reacting ethylene glycol and thionyl chloride to producing raw ethylene sulfite, a rectifying step for rectifying the raw ethylene sulfite, and a refining process for refining the raw ethylene sulfite or the rectified ethylene sulfite conducted before or after the rectifying step. The system measures a logic state width error and calculates alignment parameters, processing speed and a safety factor.
