4. Check the verticality of the rotation axis as follows:
a. Remove the protective plastic plugs from the housing of the pivots
b. Insert the pivots
7
provisionally in their respective housing (see 4.3.5 -
”)
c. Check the verticality of the rotation axis, by using a level
L
and a bar
B
which must be resting
directly on the rotation pivots

d. The perfect plumbing can be obtained, if necessary, inserting suitable shims
4
(not part of the
