ADJUSTING AND CHECKING
1. In order for it to work correctly, the rack must never rest on the
pinion. Turn all the support nuts clockwise by half a turn (
25
)
in order to lower the gearmotor. In this way, a constant distance
between pinion and rack is obtained for the entire length of
travel (
26
-A
). Make sure that the gearmotor is level by using
a spirit level.
2. Check: when the distance between rack and pinion is correct, with
the gearmotor stopped, it is possible to rock the leaf manually to
the left and right by a few millimetres.
3. Make sure that the rack is centred on the pinion (
26
-B
).
Move the leaf manually to repeat the checks along the entire length
of travel for all the elements of the rack.

figure (

.
