The spindle is advanced by moving the lever (36)
(See Fig. 6 a). The lever is fitted with a release pawl
(39) which, when pressed, renders it independent
of the hub and hence the spindle; the operator
can therefore easily vary the angular position of
the lever without movement of the spindle (Fig.6).
6c - With the hub released, moving the lever towards
the operator produces a corresponding advance of
this spindle.
6a - Moving the lever (36) towards the operator pro-
duces a corresponding advance of the spindle.
5.1) Adjustment of the advance lever
The movement of the lever
must never be loose
,
for adjustment proceed to tighten it by loading
the cup springs by means of the associated
self-locking nut, after removing the protective
cap (see Fig. 7).
6b - With the release pawl (39) pressed, the le ver is released
rom its hub and can repeat the previous travel without
the spindle moving.
