Notes: Torques indicated in drawings have precedence over those specified in the factory standards and must at all times be adhered to. For important screw connections, we recommend using a torque angle gauge. For such connections, the required tightening torques (assembly torque, angle of rotation) must be determined individually by the technical department. .
