PROBLEM TO BE SOLVED: To instruct such maintenance work that the previous maintenance work is executed as the main work and the working omission is not caused by providing a device with a working content storage means, a working content judgement means and a working conent decision means. SOLUTION: When it is decided which working content set area of a maintenance table 40 a present count exists, the set area is judged to be a first time, that means, 'cleaning'. Next, the arraying number X of the set area is recognized as X = 1 and a maintenance executing flag at this time is decided. In such a case, the maintenance executing flag is turned on until a second time. Therefore, the arraying number X is undated once and X=2, that means, αoiling' being a second maintenance executing content is instructed. Thus, since the present count is within the area of the first time, the next area, that means, the 'oiling' is instructed. By comfirming again that the maintenance executing flag of this time is turned on, the overlap of the content of the identical working content set area in the table 40, that means, the 'oiling' is eliminated. Then, the next 'oiling' is confirmed after confirming the necessity of 'exchange'. |
