Abstract
A work machine determines, when a request to restart an engine is made, whether or not a reason indicated by stop information stored in a memory is a reason related to locking of the work portion. The machine sets an operation mode of the engine and a work portion to a safe mode if it determines that the reason indicated by the stop information is a reason related to locking of the work portion. The safe mode is an operation mode for lessening damage resulting from causing the engine and the work portion to work during the work portion locked or damage resulting from an object coming into contact with the work portion during the engine and the work portion working.
