6. Slightly tighten clamping screws manually.
7. Tighten clamping screws (2) one after the other (see Fig. 14) in several passes,
with rising torque, evenly until the indicated screw−tightening torque (see Tab. 8 )
is reached at all screws.

Fig. 14 Explanation: "one after the other"
I Tip!
Several (in general more than 5 ) passes are necessary until the full
tightening torque is reached at all screws!
The shrink disc is mounted correctly and fixed when the faces of the outer ring and the
inner ring are aligned (Fig. 15). Minimum misalignments are permissible.
