Abstract
A work machine is capable of inhibiting an unintended machine motion and reducing energy consumption. The work machine includes a controller, a drive source, a controller switch to which an on-operation and an off-operation are applied, a lock operation member to which a lock operation and a lock release operation for invalidating and validating a lever operation, respectively, are applied, and a drive source switch to which a start operation and a stop operation for starting and stopping the drive source, respectively, are applied. After activated by the on-operation applied to the controller switch, the controller starts the drive source when judging that the lock-release operation is applied to the lock operation member and the start operation is applied to the drive source switch, whereas suspends starting the drive source when judging that both the lock-release operation and the start operation has not been applied.
