4.3 Assembling the frame on the foundation
Check that the frames are upright and adjust them to the same level using the nuts (2).
Fill with spacer washers the gap between the lower nut and the foundation, which
should be as small as possible.
Tighten the lower nut against the spacer washers (4). For the final tightening of the
frame, use the upper nut, which is tightened with a torque of 300-350 Nm if M24 or
500-550 Nm if M30 nut.
N.B. Tighten finally when the operating mechanism and the protective tubes
between the poles are fitted.
Foundation bolts and spacer washers are not supplied.
