Claim:
1. A handheld work apparatus having an operating rotational speed range (AD) comprising: a work tool; an electric motor configured to drive said work tool; an energy source configured to supply a voltage to said electric motor; a control unit; said electric motor being connected to said energy source via said control unit and having a power characteristic line; said power characteristic line being electronically formed as a function of rotational speed (n) for said electric motor by said control unit and having a pronounced maximum (M) and an operating plateau (AP) lying in said operating rotational speed range (AD) of the work apparatus; said operating plateau (AP) connecting to said pronounced maximum (M) of said power characteristic line of said electric motor with increasing rotational speed (n); said operating plateau (AP) expanding over said rotational speed (n) to have a rotational speed width (n an electrical setting device configured to provide a set value; said electrical setting device being configured to be operated by a user to adjust the set value; said electrical setting device being configured to, in response to an adjustment of the set value by the user, shift the position of said operating plateau (AP) out of a first rotational speed range (n, n said control unit being operatively connected to said electrical setting device; and, said electronically formed power characteristic line being changed so as to cause electric power (P
