PURPOSE:To improve changing operation efficiency, by a method wherein a device provided with an absorbing nozzle, whose tip of an absorbing pipe is provided with an inhaler of dry air and an oil sensing sensor is used so as to enable automatic changing of highly hygroscopic oil without making the oil exposed to air. CONSTITUTION:At the time of changing brake oil, an absorbing nozzle 5 is inserted into a pail can 8 so that dry air is made to inhale into the pail can which is filled with the brake oil through an absorbing pipe 7a connected with a dry air inhaler 7 filled with a desiccative. Then, when the oil is sensed by an oil sensing sensor 6 provided on the absorbing nozzle 5 and a hand operated valve V provided close to a delivery valve 3 is opened, the brake oil 13 in the can 8 is absorbed by making an absorbing pump 9 operate through the absorbing nozzle 5 and an absorbing pipe 4 and discharged into a brake oil tank from the deliver nozzle. Then the pump 9 is suspended when the tank is filled with the brake oil and the brake oil is sensed by an oil sensing sensor 11. |
