When an engine is started in a state where a support member of a multi-coupler is attached to a mating support member, the pressure of hydraulic oil increases in a detection target pipeline part. A pressure detection unit detects the pressure of the hydraulic oil in the detection target pipeline part. A connection state determining unit determines whether a tank-side pipeline part and a motor-side pipeline part are connected to each other, based on the pressure. When the connection state determining unit determines that the tank-side pipeline part and the motor-side pipeline part are not connected to each other in a state where the engine is started, a pressure increase suppression unit carries out an operation for suppressing an increase in the pressure of a hydraulic motor.
