The defect
Schwarze Industries, Inc. (Schwarze) is recalling certain 2012-2020 Avalanche M6TE, M6SE, and M6SE CNG street sweepers. The outside switch box that controls the position of the conveyor may activate unintentionally while the vehicle is running.
The risk
Unintentional activation of the switch box can advance the conveyor, presenting a crushing hazard between the conveyor and hopper, and increasing the risk of injury or death.
