12.SERVICING AND MAINTENANCE
Power supply:
Make
sure
that
the
power
supply
is
stable
at
the
rated
voltage.
Fluctuations
will
result
in
uneven
tape
speed,
and
wow
and
flutter
in
the
recorded
signal.
Cleaning:
TEAC
TZ-261A
for
Head
cleaning,
TZ-261B
for
Rubber
cleaning
should
be
used.
Demagnetization of the head:
If
the
record
or
playback
head
become
magnetized,
noise
will
in-
crease
and
fidelity
will
deteriorate.
For
this
reason,
it
is
ad-
visable
to
use
brass
or
other
such
non-magnetic
tools
when
working
near
the
heads.
Similarly,
the
use
of
a
tester
or
vacuum
tube
ohm-meter
should
be
avoided
in
checking
the
heads,
as
these
instruments
operate
by
applying
a
DC
current,
and
will
thus
induce
magnetism.
If
the
heads
have
had
any
contact
with
DC
currents
or
magnetic
tools,
demagnetize
them
with
a
TEAC
Model
E-1
Head
Demagnetizer.
Lubrication:
Under
normal
operating
conditions,
lubrication
is
required
only
once
each
year.
Before
lubricating,
clean
the
drive
belt
and
drive
pulleys.
Operate
the
deck
for
30
minutes
to
1
hour
immediately
prior
to
oiling.
After
oiling,
keep
the
deck
in
the
upright
position
for
3
to
4
hours
to
allow
thorough
absorption
of the
oil.
Approximately
once
each
year
or
after
2000
hours
of
use,
apply
TEAC
TZ-255
Lubricating
Oil
to
the
following
places
only;
Pinch roller shaft bearings **+*+* 1 drop
Capstan motor shaft bearings +++ 2 drops

Remove
the
dust

and
washer
for
access
to
the
