Complaints are reports from owners of this model year, not findings about any particular vehicle, and a model that sold in large numbers will collect more of them. They are counted here as filed; nothing is inferred from them.
If one of the hoses between the cylinder and the external counterbalance valve manifold were to fail to hold pressure, the boom could unexpectedly lower, increasing the risk of an injury.
Two 2008 ALTEC AH150s can have entirely different histories, and a recall campaign usually covers a build-date window rather than a whole model year — which a VIN does not encode, so only the door-jamb label settles it. Scanning the VIN adds the decode, the crash tests, the fuel economy and the complaints matched to that exact engine, trim and assembly plant.
