NOTE: To ensure that the foundation studs will be satisfactorily attached to the concrete, they
must be unpainted and free from pollution and dust.
Figure 3-1 Typical foundation stud assembly
In order to assemble the foundation stud or sole plate set, the machine must be suspended above
the floor by a crane. Proceed as follows, see Figure 3-1 Typical foundation stud assembly:
• Clean the parts protected by an anti-corrosive coating with white spirit
• Screw the greased leveling screws into the foundation studs (part 5) or sole plates
• Wrap a layer of tape around the upper part of the anchor bolts (part 2) according to Figure
3-1 Typical foundation stud assembly. The tape will prevent the upper part of the bolt from
being stuck in the concrete and enables it to be retightened after the concrete has set
• Fit the anchor bolt (part 2) in the foundation plates (part 1) or sole plates so that the top of
the anchor bolts is 1...2 mm (40...80 mil) above the upper surface of the nuts (part 4)
• Fit the anchor flange (part 3) and the lower nut (part 4) to the anchor bolts (part 2). Bridge
the anchor flange (part 3) to the bolts by welding and tighten the nuts. If the bridging
cannot be done, lock the anchor flange between two nuts
