A controller comprises: a low-pressure determiner that determines whether a pressure in the oil tank is lower than a first reference pressure level; a condition determiner that determines a satisfaction of a predetermined condition; and an open controller that opens the solenoid valve when the internal pressure of the oil tank is lower than the first reference pressure level, or when the predetermined condition is satisfied.
