Abstract
An adjustment circuit for a hand-operated electric power tool includes a data input device for entering information concerning the kind of material to be treated and other information relevant to the operation of the tool. The selected binary coded address word is applied to addressing inputs of a read only memory storing control words for a controlling device for a motor of the tool. Part of the bits of a control word outputted from the ROM are applied to a display device which displays the desired or actual rotary speeds of the tool and/or other data selected by the input device.
