WARNING
Danger if the coupling fractures
If you exceed the maximum diameter of the finished bore, then this can cause the coupling
to fracture in operation. There is a risk of fatal injury from flying fragments. Bursting of the
coupling can lead to an explosion in potentially explosive atmospheres.
•
Adhere to the maximum diameters specified.
The maximum diameters are listed in Section Geometry data and weights (Page 63).
Procedure
1. Remove the preservation and clean the coupling parts 1 (1) and/or 2 (2) to be machined.
2. Clamp the coupling to the areas marked with
in the diagram below.
3. Machine the finished bore in accordance with the diagram below.
