Abstract
A suspending member, such as a tether strap or the like, may by connected to improve convenience for an operator. The function of the suspending member shall be reliably performed by clearly notifying the user when the connecting part for connecting the suspending member is damaged. A ring-shaped notification member is incorporated in a connecting part for connecting the suspending member. The suspending member is inserted into both of a connecting hole in a connecting part and a notification member so as to be connected. When an end of a handle portion breaks due to long-term use, the notification member is pulled out such that the damage of the connecting part is notified.

A portable cutting machine configured to perform a cutting process, comprising:
- an electric motor configured to rotate a rotary cutting tool so as to cut a cutting material;
- a housing that includes (i) a motor housing that houses the electric motor and (ii) a handle configured to be gripped by a hand of a user of the portable cutting machine;
- and
- a notification piece;
- wherein:
- the handle includes a connecting part that is configured to receive and retain a suspending piece that is configured to be also supported by a separate component from the portable cutting machine;
- and
- the notification piece (i) has a first end connected to an inside of the handle by a fastener and a second end configured to be attached to the suspending piece and (ii) is configured to deform such that the second end moves outside of the handle due to force by the suspending piece to provide a notification of damage to the connecting part when the connecting part is damaged or broken.
