To find replacement timing, etc., of consumable parts by furnishing a memory means to store a value fond by counting the number of practice times of work detected by a work detection means by a counting means.
In the case when it is judged that timing of a timer is finished, a count value stored in an EEPROM 45 furnished on a counter base plate 4 is read out and rewritten in the EEPROM 45 again by counting up this count value. It is judged as crimping work is certainly performed when an electric power switch is continuously on for more than a specified period of time. When counting up of the count value is finished, whether this count value exceeds 1000 times or not is judged, and in the case when it exceeds 1000 times, an alarm is generated to urge replacement of a head of an electric crimping tool.
