Power
for
the turntable
platter
and
the

The motor
is adapted
to 50
or 60
cycle
(Hz)

Speed
cfiangeover
The speed
switch
lever
is
brought
into
the
required
position
(33
or
45
rpm)
by means
of
the speed
lever
18,
the switch
lever and
the
spring
lever
of the switch
levers.
lf
the
machine is
switched
off,
then
the
switch
lever is
interlocked
ty
the locking
rail 9.
The speed
is
only
pre-selected
in
this way.
The locking
rail
9 is only
released
when
the
platter
5 turns.
This
then moves
the flat
belt 15
onto
the
required
steop
of the
motor
PulleY
116.
Platter
The
platter
is secured
to
the securing
disc 1
by the bayonet
catch.
When
removing
the
platter
5
press
the securing
disc lightly
downwards
and
turn it
approximately
600
to
the right until
it is
f elt to
click out of

Flat belt
As described
above,
the
platter
must
be removed in
order
to change the
flat belt 15. Remove
the
old
flat belt. Place
the
new flat belt onto
the
running
surface of
the
flywheel rotor
30-
Changing
the drive
pulley
1.
Remove
the
flat belt 15
and the toothed
belt 109.
2,
Detach tension spring
115 from
motor
plate
125.
3.
Remove
the hex nut 111,the
adiustment
cam 112 the belt
pulley
1 13 and the
counter bearing 1 14.
4.
Loosen
grub
screws
and remove
motor
pulley
1 16. Place
the replace'
ment
motor
pulley
on the motor
axle. Remove the
taper
bush. Take
care
with the interior spacing
bush.
Adiust
the motor
pulley
vertically
(see
f
ig.
1 )
and tighten the
grub
screws uniformly.
Place the
taper
bush in
the motor
pulley
116.
5. Counter
bearing 1 14,
belt
pulley
1 1 13 and adjustment
cam 1

1 1 should now
be
tightened.
Replace
the tension sprino 115 and
the toothed belt 1O9.
Fit
the
flat

the
motor
pulley.
6.
Set the belt
pulley
1 13
to
jtscentral
position
by
turning
the regulating
knob
16.
(The
lug of the belt
pulley
should be
evident
in the middle
of
the drive
pulley).
Ser
the rated speed by
means ofthe hex nut
111.
The rated speed
may be increased by turning the
hex nut
111
in a
clockwise direction. The rated speed
may be decreased by
turning
the
screw
in an anti-clockwise direction.
Pitch control
By turning the
fine speed regulating knob 16
the belt
pulley
2 1O5
can
be moved. This rotation is
trans{erred
by
means
of the toothed belt 1O9
to the belt
pulley
1
,
thus moving the
counter bearing 1 14 and
the taper
bush
of
the drive
pulley
1 16 upwards
or downwards.
The taper bush of
the
drive
pulley
116
is designed to
vary the diameter of the
drive
pulley
thus varying the
nomlnal
speed
within the tolerance
at
+3o/o.

To Adjust the
Tone arm
Bearings
Exactly
balance
the tone arm.
Both
bearings should

of the
horizontal bearing is
achieved if
the tone arm
can freely
slide
from
the record
inside to out-
side
while the anti-skating
adjustment
is
O.5. Proper adiustment of the
vertical
bearing is achieved
when the
carefully kicked
tone
arm
swings
into balanced
posit
ion.
Adjust the
backlash
by
grub
screws
46/51 for
the
horizontal
and
vertica I bearing, respect

fix
the segment
211.
Starting
and Shutting
Off
Swinging-in
of the
tone arm
4O causes rotation
of segment
211.
As a
result,
pawl
186
and
switch arm 142
wtll operate the
switch 152
causing
the
motor 131
and turntable
5 to rotate.
After
the record
has
been
played,
the
dog M of the turntable
will
operate the shut{ff lever.
During
play-back,
the switch-off
bar 215 is
dragged
in
proportion
to the
motion
of
segment
211.For records
116
to 122
mm in
diameter, the shut-off
lever
is
gradually
pushed
to dog
M
by
the switch-oIf
bar 215
in the shutoff range.
When the dog M
con-
tacts the shut-off
lever
A, the carrier 94
will move
the shift arm 142
to
its
zero
position
and
the
power
switch will
interrupt the
supply.
At
the same time
the lifting rail
218 coupled to the switch
arm 142
will
operate
the tone arm
lift and the
tone
arm
40 will be lifted.
Adiustments

a)
Segment
Lock
the tone arm
40 in
place.
Moreover, a
play
of
0.3 to
0.5 mm
should
be
provided
between the
pawl
186
and the
stop
A of segment
211,
adjustable by slackening
the
hex. nuts 213 and shifting the
segment
211.
The
excenter
S
on segment 211
can be
used
to vary the
shut{ff
point
for
records 116
to 122
mm
in
diameter.
Pawl
With
the
excentric
bolt
adjust
