t displacement. The gear unit must not be excessively stressed when tensioning the fastening bolts. Align the gear unit exactly with the input and output units (see item 6.3.2.. Record alignment dimensions. The report must be kept with these instructions. 6.3.2.3 Mounting on concrete foundation by means of stone bolts or foundation blocks Clean the undersurface of the gearunit base. Placing stone bolts: Hook stone bolts with washers and hexagon nuts into the foundation fastening points on the gearunit housing (see fig. .

Align gear unit horizontally by in and output shafts: if using stone bolts, with shims 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 type H2, remove the airconducting 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. When the concrete has set, tighten the hexagon nuts of the stone bolts or fastening bolts to the specified torque (see item 6..
