SECTION C Operating and Maintenance Starting the Engine As soon as the engine starts, the switch should be returned to the "R" position, and the tap on the start- ing reservoir, when fitted, turned off. If the weather is warm or the engine has only been stopped for a little while, place the accelerator in the fully open position and engage the starter motor by turning the starter switch in a clockwise direction to the "HS" position (See Fig. C.1). NOTE: The above procedure is not necessary when the engine is hot. To re-start, turn the switch in a clockwise direction to the "HS" position which will engage the starter motor.
If the battery is well up, enough to turn the starter motor quickly, the engine should start. Always be sure that the starter pinion and flywheel have stopped revolving before re-engaging the starter, otherwise the ring or pinion may be damaged. Earlier Heat Start Switch The cold start switch fitted to earlier engines is shown in Fig. C.2. With this 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. C1 1. Off Position 2. Run Position 3. Heat Position 4. Heat and Start Position Where this type of switch is used, it was 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. To Aid In cold weather the procedure for the use of this equipment is as follows:- Ensure that the engine stop control is in the "run" position. Turn on the fuel supply tap of the starting aid reser- voir, where fitted. Tum start switch in direction to "H" position for fifteen to twenty seconds.
With accelerator in the fully open position, turn the C2 switch a further clockwise movement to the "HS" position thereby engaging the starter motor. 1. Off Position 2. Start Position 3. Heat Position 4. Heat and Start Position If the engine does not start after fifteen seconds, return switch to "H" position for ten seconds and then re- engage the starter motor.
