WARNING
Danger due to bursting of the coupling
If you exceed the maximum diameter of the finished bore, then this can cause the coupling
to burst in operation. There is a risk of fatal injury from flying fragments. If a coupling bursts
in an area at risk of explosion, then this can result in an explosion.
• Adhere to the maximum diameters specified.
The maximum diameters are listed in Section Speeds, geometry data and weights

Procedure
1. Remove the preservation and clean the coupling parts 1 (1) and/or 2 (2) to be machined.
2. Clamp the coupling according to the following figure.
NOTICE
Damage to the functional surface due to incorrect clamping
Never clamp the coupling part at the sealing surface of the O-rings.
3. Machine the finished bore D according to the following figure.
