1. General
The pre-tension of the foundation bolts (holding down studs) must be checked at
longer intervals e.g. during overhauls (see 0380 − 1 ).
In the area of the thrust bearing the foundation may be fastened with foundation
bolts 2 and sleeves 5 (Fig. ’A’) or with foundation fitted studs 4 (Fig. ’B’).
The remaining area is fastened with foundation bolts 3, however without sleeves 5
(Fig. ’C’).
Remark: Pay attention to the General Application Instructions 9403 − 4 for the hy-
draulic pre-tensioning jacks.
