• double section garage door
(Fig. 9)
When the door is closed, the
axis of rotation of the drive
shaft must be about 10 cm
below the axis of rotation of
the door hinge (A).
The telescopic arms must be
attached as close as possible
to the point where the hinges
are fixed to the door (B).
• garage door with horizontal
guides (Fig. 10)
The axis of rotation of the drive
shaft must be halfway
between the two bearings.
The telescopic arms must be
attached as close as possible
to the point where the upper
and vertical guides meet.
2) Fix the back plate to the
reinforcement ribbing of the
door panel using suitable
screws for the door's
structure. It is advisable to use
nuts and bolts.
Ü Position the back plate in such a way that the last section
without Ø 4mm holes (approximately 20 cm) is facing up-
wards.
ÜThe back plate has a series of Ø 8mm holes which, when it is
fixed, allow the operator to be installed at various heights.
Check that the fixing position of the back plate allows the
operator to be installed in accordance with the previously
determined shaft position.
In double operator installations, both shafts must be aligned at
the same height.

5) Fit the transmission shafts firmly onto the drive shaft and cut
them to size as shown in Figs. 6 and 7.
Ü If limit switches are used (optional), first fit the cams as shown
in Fig. 11.
6)Mount the brackets on the transmission shafts and fasten
them to the door panel using screws, taking care to maintain
perfect alignment.
7) Tighten the grub screws on the transmission shaft bushings.
8) Open the garage door and adjust the length of the tele-
scopic arms as follows:
• straight arms (Fig. 12)
