Method for monitoring the wear of manual pliers and apparatus therefor

Abstract

A method and apparatus for monitoring the wear of manual pliers. The principles focus on manual pliers, in which press elements can be pressed onto a workpiece and the degree of pressing that can be achieved by actuating the manual pliers can be adjusted with a presetting device. A reference position of the presetting device is measured prior to a first use of the manual pliers, this measurement involving actuating the manual pliers. By an adjustment of the presetting device, the press elements are brought into a position with a reference degree of pressing. Next, after use, the wear position of the presetting device is measured in the same manner, to bring the press elements into a position with the degree of pressing. A message is output when the degree of the wear position deviates from the degree of the reference position by more than the degree of wear permissible.
