The spindle is advanced by moving the lever
(36) (See Fig. 6 a). The lever is fi tted with a
release pawl (39) which, when pressed, ren-
ders 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 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).
6b - With the release pawl (39) pressed, the lever is released
from its hub and can repeat the previous travel without
the spindle moving.
