When I reverse my drive shaft my Uhing drive stalls. Why?
Chances are you have a Uhing model RG drive and are rotating the shaft in the wrong direction. The RG drive operates with the shaft rotating in one direction ONLY. Reversal is mechanically controlled with a special mechanism on the drive unit. Reversing the shaft with a model RG drive will cause the drive to stop at the end of its stroke and create undue wear on the bearings. The Uhing model RS drive does require shaft reversal in order to change travel direction.
