The defect
Alamo Group Inc. is recalling certain 2021-2022 Schwarze A9SE Monsoon (single engine) street sweepers. The open center valve manifold of the hopper hydraulic lift system allows hydraulic fluid to continue to flow into the lift system under certain conditions, which can result in the lift system continuing to rise after the operator has disengaged it.
The risk
An unexpectedly rising lift system can contact an overhead obstruction or cause debris to fall, increasing the risk of injury.
