PURPOSE:To improve controllability of a control lever for a fuel injection apparatus, by operating the control lever according to a manually produced speed instruction signal, and enabling to change the value of said instruction signal to a prescribed value when a key switch is turned OFF. CONSTITUTION:When a key switch 14 is turned ON, a relay R1 is energized and its contact (r1) is connected to a terminal (a). At the same time, a relay R2 is energized and its contact (r2) is closed. Resultantly, the voltage of a battery 15 is applied to a driving circuit 13. Subsequently, when a throttle lever 9 is set to the starting position, a throttle instruction signal S1 is produced from a potentiometer 8, and a control lever 4a is turned to the starting position by a motor 5. Then, an engine 1 is started through operation of a starter. Thereafter, when the key switch 14 is turned OFF, the relay R1 is de-energized and its contact (r1) is connected to a terminal (b). At the same time, a stop instruction signal S2 is given from a potentiometer 10 to the motor 5, so that operation of the engine 1 is stopped. |
