Depending on the structural conditions, it may
benecessary to limit the door opening angle.
In order to avoid damage to the door and the door
closer, position a door stop accordingly (see also TS
93 G Fixing Instructions, Fig. 12).
For door leaves with electro-mechanical hold-open
the following applies: The door can be opened up to
the selected hold-open point; it is at this point that a
door stop should be fitted.
