any adjustments that may be neces-
sary later on.
2) Manually place the leaf in closed
position.
3) Rest the first section of the rack level
on the pinion gear, and weld the threaded pawl on the gate
as shown in Fig.16.
4) Move the gate by hand, checking whether the rack rests on
the pinion gear, and weld the second and third pawl.
5) Position another rack element next to the previous one, using
a section of rack as in Fig.17, to synchronize the teeth of the
two elements.
6) Move the gate by hand and weld the three threaded pawls,
carrying on until you have covered the entire gate.
