CLEANING OK HEADS
AND
TAPE PATH
•
The
parts
shown
in
Fig.
55
—
tape guide, heads, pinch
roller,
capstan
and
tension
arm
—
easily
become
dirty.
They
should be kept scrupulously
clean
because
dirt
or
oil
on
these parts
can cause
inferior
sound
quality
and
stereo balance, unstable tape transport
and
other
troubles.
At
the
first
sign
of
dirt,
clean
these
parts
with the
supplied cleaning
ribbon
as
shown
in
Fig.
56.
Before
using the
ribbon,
push
down
the
pinch
roller
in
the
arrow-indicated direction
and
pull at
both ends
of the
ribbon by
hand
to
bring
it
into direct
contact with
the
capstans.
Then
try
cleaning.
Stubborn
dirt
and
deposits
can be
removed
with the supplied cleaning bar
or
a
piece of cloth
moistened
with the supplied cleaning
fluid.
HEAD
DEMAGNETIZING
As
some
static
magnetism
builds
up
in
the tape
heads
after
long-term
use,
these
should be demagnetized with
a
demagnetizer about once
a
month.
Refer
to
Fig.
57
and
observe
the
instructions
supplied
with
the
demagnetizer.

Only
the following
