6. ASSEMBLY
6.1. SLIDING GUIDE
When using the "two pieces sliding guide", carry out assembly
as described below. If an already assembled guide is available,
go to par. 6.2.
1) Assemble the two parts of the sliding guide, inserting them
in the central joint (fig. 6 ref. A) up to the metal reference
stops (fig. 6 ref. B). To facilitate fitting the sliding guide, insert
it in the central joint, compressing it as shown in Fig. 6 ref. C.
Do not use tools which could deform the guide or the joint.
2) Slide the transmission unit all the way along the sliding gui-
de (fig. 7 ref. A) bringing it near the front terminal.
3) Fit the front connection (fig. 7 ref. B) to the transmission unit
(fig. 7 ref. A).
4) Tighten the chain a little by tightening the nut (fig. 7 ref.
C).
5) Place the sliding guide on its side (fig. 8)
6) Push the carriage near the drive coupling unit (fig. 8 ref.
C).
7) Adjust the tensioner (fig. 8 ref. A) so that the central part of
the loop, formed of the upper section of the chain,
coincides approximately with middle of the sliding guide
(fig. 8 ref. B)
Warning: overtightening can damage the transmission unit and
drive coupling.
6.2. REAR CONNECTION
Fit the rear connection in the special seat on the drive coupling
unit (fig. 9).
If the operator has to be installed directly in contact with the
ceiling, cut or bend the fixing brackets (fig. 9 ref. A) and, in
the latter case, remove the cage nut. For fixing, the special
holes are used (fig. 9 ref. B). Prepare a shim of approx. 5 mm
for inserting between the rear connection and the ceiling.
