At the end of the elevation of the counterweight, check that it inserts accurately into the structure of the uppercarriage. Just before the weight comes to contact, insert the mounting bolts 12 and turn them completely in by hand. Lift up the counterweight 2 some more to the stop and tighten the bolts 12 to the prescribed torque.
