• Using suitable lifting gear, place the gear unit on the concrete foundation.
• Align gear unit horizontally by in and output shafts:
─ if using stone bolts, with shims.
─ if using foundation blocks, with the aid of the set screws (if available).
• If considerable forces may apply, use stops to prevent the unit from displacement.
Before pouring the concrete foundation, fill up the openings in the foundation blocks with
adequate material such as polystyrene.
With types H1 and H2, remove the airconducting cowl before tightening the foundation bolts
and then bolt it back into position.
• Pour concrete into the recesses of the stone bolts or foundation blocks.
