Defect summary

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.

Consequence

Remedy

Dealers will mount additional valves, free of charge. Owner notification letters were mailed on December 6, 2022. Owners may contact Alamo Group's customer service at 1-830-379-1480.
