The defect
Altec Industries Inc. is recalling certain 2015-2018 LR7, ALB, AC18, AC23, and AC38 vehicles built on an International N9/N10 chassis. During an HC Desorb cycle, the vehicle's idle will rapidly rise causing an increase in pump flow. The increased pump flow can result in the moving speed of the boom changing.
The risk
The change in boom speed can result in unintended positioning of the boom, increasing the risk of injury.
