Abstract

PURPOSE:To easily judge the life of the working liquid and improve the working efficiency by installing a judging and display circuit which displays the exhaustion of the life of liquid from the result of the comparison between the liquid life standard accumulative time and the accumulative time for the standard working condition which is obtained by the conversion calculation of the accumulative working time for each working condition in a calculation circuit. CONSTITUTION:The accumulative time for each working condition for fresh liquid is detected by a counter 16 at each completion of work. The accumulative working time for each condition is allowed to pass through a coefficient filter 18 for each condition, and sent into a calculation circuit 20, where the accumulative working time for each condition is converted to the arbitrary working condition (working condition used most frequently) and the standard working time. The conversion value is sent into a judging circuit 22, and compared with the preset working liquid exchange time (standard value), and only the time when the conversion value exceeds the standard value, signal is sent to a display circuit 24. A lamp for showing the working liquid exchange is lighted up by the indication circuit 24 on the basis of the input signal.
