Brake
Mechanism
Adjustment
A
brake
lining
is
employed
to
stop
the
platter.
A
worn
brake
lining
will
result
in
the
platter
not
stopping
quickly
or
stopping
with
abnormal
noise.
If
these
troubles
occur,
adjust
as described
below.
@ The platter makes a noisy stop.
1.
Brush
the
friction
surface
of
the
brake
lining,
which
contacts
the platter,
with a brush several
times. Refer
to Fig. 13.
2.
Carefully
wipe
the
inner
platter
surface,
which
contacts
the brake lining, with a soft cloth (such as gauze) dipped
in alcohol.
@ The platter does not stop correctly due to a defective Fig. 13
brake. (The platter does not stop within one rotation.)
When
the
brake
lining
is
worn
out.
1.
Completely
remove
the
brake
lining
using
thinner,
then
attach
a new
lining.
2,
Remove
the
paper
covering
from
the
adhesive
rear
side
of the
new
brake
lining,
then
attach
the
brake
lining
in
the
previously
attached
position.
3.
Glue
the
brake
rod
to
the
brake
lining
at
the
double
lining position
(as shown
by arrow A in Fig. 15) with
rubber cement.
When
the
solenoid
coil
is
improperly
positioned.
1.
Fit
the
brake
lining
inside
the
platter
(The
function
is
the
same
as
a
normal
brake).
Slightly
loosen
the
2
solenoid
mounting
screws,
then
adjust
the
solenoid
coil
position
until
the
clearance
between
the
solenoid
coil
end and
the
plunger
head
is
9mm,
(Refer
to
Fig.
14.)
After
the
adjustment,
be
sure
to
re-tighten
the
screws
firmly
(Refer
to Fig.
15).
e
How
to
use
the
brake
clearance
adjusting
boss
B.
(Refer
to Fig. 15)
When
replacing
the
brake
rod
with
a
new
one,
turn
the
boss fully counterclockwise,
then mount
new brake
rod.
After mounting
the brake rod, gradually
turn the boss
clockwise
(This
narrows
the
clearance
between
the
platter
and the brake lining) until the contact
sound of
the
brake
lining
and
platter
is
eliminated
when
the
platter is stopped
by touching
the stop switch.
Finally,
confirm
that
the
brake
lining
does
not
contact
—
eat
the
platter,
while
the
platter
is
rotating
at
the
speed
TAGUAIAQ
SIH
33-1/3
or
45
rpm,
by
noting
the
sound
and
observing
the
stroboscope.
If the platter contacts the brake lining during rotation,
turn the boss counterclockwise to increase the clearance
between
the
brake
lining
and
platter.
After
replacing
the brake rod, be sure to apply a drop of silicone (in the
order of million unit) to the part of the motor board
stud
which
contacts
the
brake
rod.
