Abstract
A hand-held tool, such as a disc grinder, is used to perform work at a high work site, a countermeasure is taken to prevent the hand-held tool from falling by using a suspension tool, such as a tether strap. If a coupling part that couples the suspension tool to the hand-held tool is damaged, this fact is notified to a user. Thereby, an original function of the suspension tool can be reliably performed. If a large impact is applied to a coupling member via a suspension tool, the coupling member is displaced to a second position, due to the deformation of a first position retaining member. A conductive portion disengages from contacts to cause a power circuit to be shut off, thereby prohibiting a main body part from being activated.
