4. Adjust the height
and distance from
the gate as shown
in Fig 11.

tor to the founda-
tion plate, tighten
nuts as shown in
Fig. 12.
1. Place the three threaded
dowel nuts on the rack
element, positioning them
at the top of the slot. In
this way, the slot play will
allow any adjustments to
be made.
2. Manually move the leaf to
its closed position.
3. Lay the first piece of rack
level on the pinion and weld the threaded dowel nut to the
gate as shown in Fig. 15.
4. Move the gate manually, checking that the rack is resting
on the pinion, then weld the second and third dowel nut.
5. Place another rack element next to the previous one, use
a third piece of rack (as shown in Fig. 16) to synchronize
the teeth of the first two elements.
6. Move the gate manually and weld the three threaded
dowel nuts. Proceed as described until the gate is fully
covered.
4.4. INSTALLING THE RACK
4.4.1. STEEL RACK TO WELD (Fig. 13)
4.4.2. STEEL RACK TO SCREW (Fig. 14)
To access the electronic board, route the cables through the
appropriate hole, using the supplied rubber cable-clamp.
Make sure to strip the jacket on all cables so that the clamp
holds single cables only (Fig.10 - Ref. B).
1. Manually move the leaf to
its closing position.
2. Lay the first piece of rack
level on the pinion and
place the spacer between
the rack and the gate,
positioning it at the top of
the slot.
3. Mark the drilling point on the
gate. Drill a Ø ¼ inch hole and apply thread with a Ø 5/16
inch male tap. Screw in the bolt.
4. Move the gate manually, checking that the rack is resting
on the pinion. Repeat step 3.
