Fig.9
For a correct positioning of the other
elements and to assure their straightness,
it is necessary to employ a rack
element using it as support and
reference (fig.9).
It is besides necessary to assure an
aperture of 2 mm between rack and
pinion gear, so that the gate weight
doesn’t rest on the gear-motor pinion
gear (as shown in the fig.8).
Release the gear-motor as indicated by the fig.2 and open entirely the gate.
Put a rack element on the pinion gear and fasten it to the gate with screw and
spacing bars.
Move the gate manually bringing the pinion gear into line with the
last spacing bar.
Fasten the rack element for good.
