Once the knob is in the OFF-position please turn the knob forcefully (with high torque) into the ON position. The shaft will definitely not break. Before that please make sure that the padlock slide of the knob (pages 2 and 4 of the enclosed file) is fully inserted. kind regards Attachment 3RV1742 manual.pdf (44 Downloads)
