Cleaning Heads and Tape
Path
Dirty
heads and
tape path
will
cause
:
.
Loss
of high
Írequency
response
which results
in
poor
sound
qu ality
.
Loss
of
sound volume
in
recording and playback
.
Drop-out
.
Unsatisfactory results
in

erasing
.
lncrease
of wow
and
flutter
Therefore,
the
mirror-like
finish
on the face of all
heads
and
tape path must
be
preserved
to
get
optimum perÍormance.
Generally cleaning heads
after
every
I
hours
will
be
sufficlent.
But
it
is recommended
to
clean
the
heads
and tape path carefully
before starting a valuable
recording.
1. Remove
the
head cover
by pulling
it
up.
2.
Take
the
supplied head cleaning
tip or a
soÍt
cloth
and
carefully
wipe
the
heads and other surfaces upon which the
tape travels.
lf the
deposits
are hard
to
remove, moisten
the
tip
or
the
cloth
with a
head
cleaning solutíon
or
denatured alcohol
and
repeat
cleaning.
For
easier access
to the pinch roller, push
back
the wire
lever
of the
automatic shut-off
mechanism
and
fix
it
there
with
a
string or so,
and
then
set the Function selector
to >
(FWD);
for
easier access
to
the
capstan, set
the
selector
to »
(FF).
.
Remember
to
remove string when
cleaning
is
completed.
.
Do not allow metallic materials
near
the
heads.
'Discard the
tip or cloth after
use
to
prevent
contamination
of the
cleaning solution or
alcohol remaining in
the
container.
Demagnetizing
Heads
Continuous use, or the accidental touch, of
a
piece of magnetized
steel (screwdriver, scissors, etc.)
will
magnetize
the
heads,
causing an increase
in
tape
noise.
lt
is
recommended that the
heads be demagnetized
periodically
to
maintain optimum
per-
formance. The
SONY Head Demagnetizer HE-2 (optional)
is
recom mended.
Cleaning Cabinet
Clean
the
cabinet
with a soft cloth
and
mild
detergent.
Do not
use solvents such as alcohol, benzine or thinner
as they
could
mar
the finish
of the
recorder.
Lubrication
To maintain the optimum performance
oÍ the
recorder, lubrication
is
required every
6 months.
Consult your
nearest
SONY dealer
for
lubrication
of your
recorder.
Use
light
machine
oil
and lubricate
the
capstan,
pinch
roller
shaft and idler
shafts.
Avoid
excessive
lubrication.
lt willcause
slippage of the
mechanism and contamination
of your
tape.
Make sure all
excess
oil
is
wiped
off completely.
Remove
the
top panel and take
out the
cap
of
pinch roller.
Lubricate
the
pinch roller shaft,
capstan, and
idler shaÍts
with 1
drop
each
of light
machine
oil.
.
Before removing the top panel, disconnect the
AC
