FIG. 6
The spindle is advanced by moving the lever
(36) (see Fig. 6a). The lever is fitted with a release
pawl (39) which, when pressed, renders it inde-
pendent 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 corre-
sponding advance of this spindle.
6a - Moving the lever (36) towards the operator
produces 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).
SELF-LOCKING NUT
6b - With the release pawl (39) pressed, the lever is
released from its hub and can repeat the pre-
vious travel without the spindle moving.
