Zusammenfassung:	Even if the working oil of the hydraulic system is replaced and the working oil is a mixed oil formed by mixing mineral oil and biodegradable oil, the damage of the hydraulic parts of the working machine caused by the performance reduction of the working oil can be prevented. Therefore, the storage device stores oil replacement history information of the working oil, an oil type determination value for determining which of the working oil is a mineral oil, a biodegradable oil, or a mixture of the mineral oil and the biodegradable oil, and an abnormality determination value for each type of the working oil. The controller confirms whether or not there is oil replacement information in which the oil type determination is not performed in the oil replacement history information, and if there is oil replacement information in which the oil type determination is not performed, determines the type of the working oil on the basis of the respective values of the plurality of oil properties detected by the oil sensor
