SECTION C Operating and Maintenance Preparation for Starting Check the radiator water level. Check the engine sump oil level. See that there is fuel oil in the tank. Check that the starter battery is fully charged and that all electrical connections are properly made and all circuits in order. Starting the Engine If the engine is warm, turn starter switch in a clockwise direction to the "HS" position (see Fig. C.1). As soon as the engine starts. release the switch to the "R" position. Be sure that the starter pinion and engine have stopped rotating before re-engaging the starter motor, otherwise damage may result. Fig. C.1 1. Off Position. 3. Heat Position. 2. Run Position. 4. Heat and Start Position. If weather is cold, turn starter switch to the "H" position (see Fig. C.1) and hold it there for fifteen to twenty seconds. Then turn the starter switch to the "HS" position, thereby engaging the starter motor. If the engine does not start after twenty seconds, return the switch to the "H" position for ten seconds and then re-engage the starter motor by switching to the "HS" position. As soon at the engine starts, release the switch to the "R" position. Earlier Heat Start Switch The cold start switch supplied with earlier engines is shown in Fig. C.2. With this type of switch, starting a warm engine is effected by turning the switch in a clockwise direction to the "S" position. In cold weather, the switch should be turned to the "H" position for fifteen to twenty seconds and then to the "HS" position in order to engage the starter motor. As soon as the engine starts, the switch should be returned to the "0" position. When this type of switch is used, it was sometimes customary to have a separate switch for the electrical circuits and this should be turned on before starting the engine and turned off after stopping the engine. Starting the Engine (Alternative Method) With some engines. a different starter switch may be found and the cold start aid operated by means of a separate push button switch.
