Moving the operating
switch also releases the start lever
(183), pulling
it towards
the main cam
by
means of the
tension spring (182). This
causes coil spring to bring the
143
shut-off lever (222) within range of the
main cam dog.
Thus the shut-off lever drives the main cam.
To prevent malfunctioning, the operating switch is locked
during the start cycle (that is, while the main cam is
183
turning).
Just before the main cam reaches its neutral
Position (at the end of the
change cycle), the start lever
is pushed clear of
the main cam by the start pin of
the
main cam.
This restores the switch lever and operating
switch to their original positions.
After Instal lation and also after moving the changer, the
147
unit should be started with the tonearm
locked on the
rest. This will
automatically re-adjust the shut-off lever,
which may have shifted out of
position.

Manual start
When the tonearm
(16) is swung inward by hand,
the pawl on the
switch
arm drops into a support on
the base plate, holding the
switch arm in this position
and the idler wheel (108) in contact
with the
platter.The slide (138)1inked with the
switch arm actu-
ates the power switch and
sets the turntable platter rotating.
On
reaching the run-out groove, the tonearm
automatically re-
turns to its rest
position and the unit shuts itself off. (See shut-
off mechanism, next side). However, if the
tonearm is lifted off
the record manually and
returned to the rest, the tabs of the arm
segment (246) release the
pawl. The
torsion spring
(176)
then
returns the switch arm to its initial
position, opening the power
switch and
disengaging the idler wheel.
Stop switching
When the operating lever is moved to "stop", the starting lever
(183) is pushed forward. As a
result the shut-off linkage comes
into contact with the main cam. The
svvinging
lever
(236)
remains
in its stop
position.

When the tonearm is on its rest and the operating lever is pushed
to "stop", the
