Accurately clean the surface of the flange (ref.
Fig. 8) making
sure to remove all metallic residue produced by the previous hole
drilling operation;
Fit the two parts of the roller bearing (ref.
Fig.8) on the flange, and
correctly join them by pressure, to form a single body;
The closure of the roller bearing on the flange is definitive. Any
subsequent attempt to open it could damage the couplings,
thus compromising their operation.
Do not lubricate the flange and bearing with grease or
equivalent substances to avoid subsequent accumulation of
dust and dirt.

Using the hole on the flange in Fig.7 ref.
as a reference, drill a
through hole (diam 10.5 mm) on the winding shaft;
Insert, in the hole you have just drilled, the securing screw in Fig.7
ref.
, tightening it to rest on the washer and self-locking nut;

If, in chapter 1.2, you have measured a winding pulley diameter
of 220 mm, you must fit the crown adapters, as shown in Fig. 9.
Couple the adapters in the housings on the crown. Fasten the
countersunk screw to firmly secure one of the two adapters on the
crown. Fasten the second adapter with the rounded head screw
in order to anchor the shutter.
Anchoring the crown on the shutter could be the cause
of the loss of the initial positions of the mechanical
travel-limit devices. For this reason, we advise you
NOT TO REMOVE the service bracket, ref.
Fig.1 on
page 3.

Drill a hole with a diameter of 10.5 mm on the shutter in
correspondence with the securing hole on the transmission crown
gear. To definitively secure the shutter to the crown use the relevant
rounded head screw and its washer, Fig. 10 ref.
.
