ADJUSTMENT OF NEW REEL BASE
For details of
back tension measurement,
pleasn
refer
to
the applicable Service
Manua
l,
"Adjustment of Mechanism"
section.
The
'L
adjustment procedure of the new reel base.differs
from that employed with the old
reel. The correct
steps
should
be
as
follows:
1)
With the
POWE R
switch ON,
set
the
deck
to
PLAY
mode
-
the back tension pulley should
engage
the reel
base.
check
sectiontrtFig"
6).
This gap
mLrst be
at
least
0.5 mm (1
164
in.)
or
more.
lf
smaller,
!f
e gap must
be
widened by
bending
sectionltronce
the required
d
imension
of
0.5 mm
(1
164
in.) or
more
is
obtained,
set
the deck
to
FAST FORWARD mode to
conf
irm
that the
back tension
pulley
is
completely
separated
from
the reel
base.
2)
Adjustment of take-up
tension
at
19.5
cm/sec.
(7-t 12
ips) -
PLAY
mode
Use
a
tension
gauge
to
measure
take-up tension.
lf
there
is a
deviation from the rating
of
35-
1
009
(0.07
-0.2
lb),
repeat adjustment of
the
coi I
spring
until you
obtain
a
rated tension
within
the rated
coil
length
of
12-1 4 mm
(15132-35164 in.),
setting the
deck
to
FAST FoRWARD
mode,
measure
back tension of the supply
reel. This must
register
within B-169 (0.016-0.032 lb). lf
lf
otherwise ,
readjust the adjustment screw
f
or
tension brake (refer to sectionffiof
Fig.
8).
.
3)
Adjustment of take-up tension
- FAST
FORWARD
mode
Load
a
tension test reel on the
base
a
nd
set
the
deck
to
FAST FORWARD mode. Adjust the
tension adjusting screw
(section@of
Fig.
8)
in order to obtain
a
starting tension of
approximately
22Og
(0.4 lb) at FAST FORWARD
Once
this value
is
obtained, continue
sliding the
reel
for
30
seconds
(no more)
and
make
f
inal readjustment of
the
screw
to
obtain
._-
the correct FAST FoRWARD take-up tension
rating which should
be
within 180-200g (0.30-
o.4
lb)
