In order to prevent the weight of the leaf from affecting the
gearmotor, it is important that there is a play of 1÷2 mm between
the rack and the pinion as shown in Figure 10.
8. Slide the leaf, using the pinion as a reference point for the fastening
the other elements of the rack.
9. Cut away the exceeding part of the rack.
10. Open and close the gate several times and make sure that the rack
is aligned with the pinion with a maximum tolerance of 5 mm. More-
over, check that the play of 1÷2 mm has been respected along the
entire length between the pinion and the rack.
11. Thoroughly tighten the two fixing nuts of the gearmotor making sure
it is well fastened to the ground. Cover the fixing nuts with the rela-
tive caps as shown in figure 11.
