    Abstract: PROBLEM TO BE SOLVED: To enhance an operating efficiency by dispensing with a complicated operation wherein an engine is once stopped and started again at the time of switching forward and reverse rotation of a cooling fan. SOLUTION: A forward rotation position A for rotating forward the cooling fan 36, a reverse rotation position B for rotating reversely the cooling fan 36, and a stop position C for stopping the rotation of the cooling fan 36 are arranged on a selector valve 120. Then, the cooling fan 36 is switched to forward rotation and reverse rotation by controlling the switching of the selector valve 120, and the rotation of the cooling fan 36 is stopped at the time of switching of forward rotation and reverse rotation.
