FIXING OF RATCHET
Model
Fig. 7
For the correct installation of the ratchet unlock the reduction gear as shown in (fig. 3) and bring the
gate to complete aperture.
Lay one element of the ratchet on the pinion and fix the latter with screws and tingles to the gate.
Manually move the gate bringing the pinion in correspondance with the last tingle. Definitively fix
the element of the ratchet.
For the correct positioning of the other elements and to ensure they are straight it is necessary to
use a ratchet element using it as reference and support.
Moreover it is necessary to ensure some air between the ratchet and the pinion of about2
mm(indicative
measure), so that the weight of the gate does not bear upon the pinion of the reduction gear.
