The following operation steps are shown on model 223.1 on the left side of the vehicle and must be similarly performed on the right side of the vehicle. The superordinate service document as well as the safety information in the service document must be observed.

The diagrams show the vehicle from the perspective of the technician. At the same time, this view also specifies in what direction the rivets must be set.
