Patent ID: 7372226

Claim:
A method for shutting off a drive motor ( 12 ) of a power tool that drives a tool, the drive motor ( 12 ) being shut off as a function of a variable threshold value (E 1 ) if the tool jams, wherein the threshold value (E 1 ) is determined in at least one predetermined time interval (T 1 ) as a function of a current load speed (n 1 ) and a no-load speed (n 0 ), wherein a current load speed (n 1 ) is compared with a numerical interval listed in a table—the numerical interval relating to either a load speed or a no-load speed—and is assigned to the new threshold value (E 1 ), and wherein, at low load speeds (n 1 ), the threshold value (E 1 ) is lowered as a function of a selectable factor.
