The control unit prevents valve bleed if the control valve is in its extend or retract position under command of the operator. The control unit prevents a valve bleed if a temperature of oil in the reservoir is not less than a reference temperature. The control unit prevents a valve bleed if a speed of the vehicle is less than a reference speed.
