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. 6b).
6b - With the release pawl (39) pressed, the lever is released
from its hub and can repeat the previous travel without
the spindle moving.
6c - With the hub released, moving the lever towards
the operator causes a corresponding advance of
the spindle.
FIG. 7
6a - Moving the lever (36) towards the operator;
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).
