In the vertical position and from the resting position
(fig.6a), raise the rotor, levering on a pin inserted in the
hole in the shaft, until the pin can be rested under the
coupling (64.22).
In this position (fig. 6b), by tightening the screws
(64.25) uniformly, the shaft (64.00) is locked tight in
the coupling.
Remove the pin.
Only for MXV 50, in the vertical position from the
resting position screw up the screws (64.25) without
blocking the shaft (64.00), so screw up the screw
(64.34) (fig.6c) in the coupling (64.22) until the screw
is supported. In this position, by tightening the screws
(64.25) uniformly, the shaft (64.00) is locked tight in
the coupling.
Mount the motor as indicated in
