Abstract
A work machine having working equipment includes a power source that outputs a driving force for operating the working equipment, a controller, and a solenoid valve controlled by the controller. When it is determined that an abnormality has occurred in the power supply circuit connecting the controller and the solenoid valve, the controller outputs a command for controlling the power source so as to limit an operation of the working equipment.
