Abstract
A work machine includes an operation intention determining section that determines whether or not an operator has an intention of operating an operation member based on a state change of the operation member, a current supply section that supplies a current to a solenoid valve device based on an operation of the operation member, and a current control section that permits supply of a standby current from the current supply section to the solenoid valve device when it has been determined by an operation position determining section that the operation member is disposed within a preset neutral range and it has been determined by the operation intention determining section that there is an intention of operating the operation member, the standby current being lower than a current of the time when a hydraulic actuator starts driving.
