& nbsp; The person in charge of operating the leveling machine must undergo professional training, hold a certificate, and accurately use labor protection equipment.2. During the adjustment, manual, and semi-automatic operation processes, coordinate command, issue commands uniformly, and ensure safe production.3. Before driving, it is necessary to seriously inspect whether all parts of the leveling machine are flexible and whether the fasteners are secure. Only after confirming that all parts are normal can production begin.Before operation, check whether there are any obstacles to the operation of the machine in the vicinity of each part, and especially clean up everything near the rollers.&Nbsp; 5. The leveling machine should be kept clean at all times. After use, each roller hand, table, cover plate, shell, etc. should be wiped clean and oiled. The surface of the roller wrist should be oiled, and the chain should be oiled every 30-50 working hours to avoid rust and affect the normal operation of the machine.&Nbsp; 6. According to the thickness of the steel plate, adjust the pressing amount of each feeding roller and hinge roller. The operator should adjust the curvature as early as possible to ensure normal operation.&Nbsp; After the office is over, be sure to cut off the power and clean the leveling machine.  8. After driving, the driver should not approach any moving parts with their own board, nor should any other object approach any moving parts, in order to avoid accidents and personal life.  9. When the leveling machine is running, especially during feeding, attention should be paid to the operation of the board at all times. If any deviation, jamming or other abnormal conditions are found, the machine should be stopped immediately and the power should be cut off for inspection.
