Dismounting the clamping ring hub
1. Loosen the clamping screws evenly one after the other.
(
Stop!
Each screw must only be loosened by half a revolution per pass! Unscrew
all clamping screws by 3 − 4 threads.
2. Remove the screws next to the forcing threads and screw them into the other
threads until they have contact.
3. Tighten the screws in the forcing threads crosswise and step−by−step so that the
clamping ring is loosened.
4. Clean and grease all contact surfaces including threads and head of the clamping
screws before reassembly.
