Disclosed is a method of preventing thermal shock to a hydraulic motor in an open-loop hydraulic system. The method comprises the step of circulating warm oil through the motor when it is not in use. Preferably the method includes the further step of returning the warm oil to the tank after it has passed through the motor, and where appropriate it may also include the preliminary step of lowering the pressure of the warm oil before it is passed through the motor.
