SOLUTION: A circuit is formed by connecting in series the oil terminal machine 1, a PIF device (an oil feed control device) 10 and the main device 14, and the oil feed terminal machine 1 is provided with a receiving section 2 for receiving data transmitted from the PIF device 10 and a transmitting section 3 for transmitting data to the PIF device 10. 'An oil feed amount data 4, a nozzle slip-off sensing data 5, the present oil data 6 and the last oil feed data 7' are formed on the oil feed machine 1, and an alarm sound output waiting time setting section 8 and an alarm 9 are provided therein. |
