- Pull the split pin as per picture 11d then screw the C hub manually until it reaches the
end position.
- Tighten the C hub by inserting the special C key in the C hub slot (fig.11e).
- Remove the split pin from the cylindrical protection bush.
- To adequately tighten the hub must be given a hammer blow on the special key C (you
can also use the pliers, hammer side, to fix the spring-loaded weights).
If during the assembly phase the hub C should freeze before completing the tightening
phase, proceed as follows:
- Make a complete turn in the opposite direction of the hub C
- Remove the split pin B
- Push the hub C in the direction shown in figure 11f and then tighten the hub until it stops.
IMPORTANT
During the tightening phase, check that the ratchets are always closed inside the locking
sleeve.
IMPORTANT
In case of failure of the automatic locking device, it is possible to remove the wheel that may
be present on the machine acting on the rear side of the caisson as indicated in Figure 11g:
