Hand-held or semi-static electric tool unit e.g. grinding tool, processes load data to make servicing prediction or prediction of remaining problem-free operating period or to detect fault condition

摘要

The device has a device for storing machine-related data, a processor-controlled device for acquiring load states during operation off the tool unit (2) and for converting the states into load data for storage in a memory device and a processor-controlled device (14) for processing load data to make a servicing prediction or a prediction of the remaining problem-free operating period or to detect a fault condition.
