 The boiler was lit on 18 September, and this time there were problems with smoke filling the smithy, which required further minor modifications.Steam was raised on 20 September, and the first attempt to run one engine was made the following day, with John Thorlby, who had been superintendent of the pumping station until his retirement, demonstrating the start-up procedure.The boiler feed-pump glands had to be repacked, and the camshaft had to be stripped down to clear the oil ways, but after attention to these items, the engine ran satisfactorily.
