Place
an
empty
reel
RE
702
(4"
diameter
hub)
and
spring
scale
on
the
right
reel
table
(see
figure).
Place
the
unit
in
the
forward
play
(
Bm)
mode.
Allow
the
rotation
of
the
reel
to
draw
the
scale
toward
the
hub.
Hold
the
spring
scale
with
enough
force
to
allow
a
steady
reading.
It
should
be
60°64
grams
(torque:
300320
g-cm).
If
adjustment
is
required,
adjust
the
slider
of
R-8
(A).
Place
an
empty
reel
on
left
reel
table
and
depress
the
reverse
button ( =a).
Repeat
above
step
3,
4,
5
of
forward
take-up
torque
section.
If

is
required,
adjust
the
slider
of
R-6
(C)
(60v64
grams).

Place
an
empty
4"
hub
reel
and
spring
scale
on
left
reel
table.
Wind
several
turns
of
string
counter
clockwise
around
the
hub
and
attach
a
suitable
spring
scale
to
the
free
end
of
the
string.
Pull
the
spring
scale
away
from
the
reel.
Take
a
reading
only
when
the
reel
is
in
steady
motion
since
the
force
required
to
overcome
static
friction
will
produce
a
false,
excessively
high
initial
reading.
The
reading
should
be
2607300
grams
(1,300%1,500
g-cm).
If
adjustment
is
required,
adjust
the
brake
adjusting
spring
arm
for
the
proper
brake
torque.
.
To
check
and
adjust
the
right
reel
brake
repeat
all
steps
as
de-
scribed
for
left
reel
with
the
exception
that
all
directions
of
rotation
are
clockwise.
Adjust
brake
adjusting
spring
arm
(right)
for
proper
brake
tension.
IMPORTANT:
The
difference
in
torques
between
the
right
and
left
brake
should
be
kept
within
10
grams
(50
g-cm).
