ABSTRACT:
A rotatable, portable drum auger drain cleaning device includes a rotational control which is biased towards the off position. The rotational control device is utilized in conjunction with a motor and the drum to direct drum rotation. The rotational control is typically biased in the off position making it the default position. The rotational control must therefore be manually moved to either a forward or reverse position. When in the forward position, the rotational control can be locked, and when in the reverse position, the switch must be manually held in position or the switch will return to the off position.
