摘要

The operating units' drive parts are positioned outside the side walls of the machine-chassis (4) and have protective cladding (1) possessing locks containing electronic or electro-mechanical circuit elements connected to the drive motor's ignition current circuit and or couplings. The circuit element is in the form of a safety switch (3) fixed to the machine chassis and contains a coded actuator (2) placed on the inner walls of the protective cladding. A guide part (25) fits into a recess. The maintenance key (20) fitted with an actuator and guide part is inserted into the safety switch and into the recess.
