MECHANISM
NOTE:
Be
sure
that
the
power
is
turned
off
prior
to
making
any
adjustments
to
the
brakes,
1.
Screw(A)
for
the
left
brake
(as
viewed
from
the
front)
must
be
adjusted
so
that
there
is
a
clearance
of
1
mm
between
lever(C)
and
lever(E).
Screw(A)
for
the
right
brake
must
then
be
adjusted
so
that
lever(B)
is
parallel
to
lever(C).
2.
Push
the
plunger
until
there
is
contact
at
(a);
i.e.,
until
the
clear-
ance
has
been
eliminated,
but
make
sure
that
the
plunger
is
not
pushed
so
strongly
that
the
levers
(E)
(C),
and
(B)
are
deflected
—
they
must
remain
in
a
horizontal
plane.
3.
Position
the
solenoid
housing,
while
the
plunger
is
pushed
as
des-
cribed
in
step
#2
above,
so
that
the
gap
at
(f)
(the
distance
be-
tween
the
leftmost
edge
of
the
plunger
and
the
leftmost
edge
of
the
solenoid
housing)
is
between
11
to
12
mm.
When
the
solenoid
housing
is
so
positioned,
the
plunger
should
be
able
to
be
deflect-
ed
between
1
to
2

TORQUE
NOTE:
Before
making
any
brake
adjustments
or
measurements,
make
sure
the
power
is
off,
1.
Mount
an
empty
7”
reel
onto
either
reel
table
and
attach
a
spring
scale
to
the
reel
with
a
string.
2.
Smoothly
pull
the
scale
away
from
the
reel
under
test
and
note
the
torque
value
when
the
reading
on
the
scale
is
steady.
The
proper
torque
values
are
given
in
the
chart
below.
3.
Follow
steps
1
and
2
for
each
measuring
condition;
i.e.,
(A)
through
(D)
in
Fig.
2-4.
4,
If
the
forward-direction
torque
is
not
correct,
change
the
hook-
ing
position
of
the
spring
hanger
(reference
(D)
in
Fig.
2-3)
for
the
corresponding
brake
requiring
adjustment.
If,
after
the
for-
ward-direction
torque
has
been
properly
adjusted
and
the
reverse-
direction
torque
is
not
correct,
or
the
forward-direction
torque
is
still
not
correct,
check
to
see
if
the
brake
felt
pad
is
worn,
and
also
check
that
the
brake
mechanism
is
properly
aligned
as
ex-
plained
in
Section
2-3,
“Brake
Mechanism”.
If
necessary,
replace
the
entire

REEL
TABLE
HEIGHT
1.
As
a
general
reference,
the
height
of
the
reel
table
should
rough-
ly
correspond
to
a
distance
of
38
mm
(1-7/16")
between
the
chassis
of
the
deck
and
the
rubber
mat
on

from
this

loosen
the
two

.
For
fine-adjustment,
check
that,
while

starting
at
the

check
that
the

speed
does
not
vary
any
more
than
the

so
that
there
is
never
a

heads
so
that
the
proper

is
obtained
for
each.
2.
Coarse-adjust
the

of
the

and
playback
heads
by
observing
each

a
tape
threaded.
3.
Load
a

test
tape
and
play
it
in
the
forward

tion.
4,
Fine-adjust
the
height
of
each
head
as
shown
in
Fig.
2-12.
When
adjusting,
make
sure
ail
the
screws
are
turned
proportionately
so
that
the
tilt
and
azimuth
previously
adjusted
is
not
altered.

If
required,
coarse
adjust
any

requiring
tangency
correction.

Lubrication
is
normally
not
necessary
except
at
the
points
shown.
1.
Place
the

position.
2.
Apply
a
few
drops
of
