Heat the exposed center portions of the tie rods with a propane flame or equivalent to 275° 25°C (527° 45°F). Perform this process in order to obtain the turning angles of the tie rod. Direct the flame away from the cylinder of the hammer. Thin steel sheets can be placed behind the tie rods in order to assist in deflecting the flame from the cylinder. Do not heat in one spot. Do not heat tie rods to a temperature that is greater than 300 °C (572 °F).Note: The tie rods must be heated in the proper sequence.
