FIELD: process engineering.
SUBSTANCE: invention relates to control over cutting members of dual-action cleaning machine with rotary drums. Proposed method comprises reception of signals from first and second transducers arranged at machine body indicating machine path and position relative to working face and signals indicating the rotary handle position relative to face bottom. Then, machine crosswise roll is defined. Said signals are processed to reveal if said machine departs from drift working face. Then, rotary handle position is defined. Rotary handle position is compared with limiting trimming at the face to stop the machine in case said position is lower that said limiting trimming magnitude. Machine resumes its motion when said rotary handle stays at required position.
EFFECT: ruled out trimming below the face, limited trimming at sections other than face end sections.
