LUBRICATION
Before
applying

turntable, remove
the
turntable
platter
by
using
the
following
procedure:
1.
Return
the
tonearm onto
the arm
rest, then support
the
tonearm
with
the arm
clamper
of the arm
rest.

not be
removed easily,
pull
it up
strongly, with care taken
not to
damage
any
part
of the
turntable.
WHEN
LUBRICATION
IS
REQUIRED
. . .
Mechanical
noises
and wow and
flutter usually result
from
the
lack
of
lubricant
in
rotating parts. Lubricate
the
specified
spots
at
least once every
two
months
if
your turntable
is
used
for
home
entertainment,
and two to
three
if
used
for
professional
purposes. Apply
one or two
drops
to the
base
of
the
center shaft Fig.
19.
When
lubricating,
be
careful
not to let oil
adhere such
as
the
motor pulley, belt,
or
inner rim.
If oil
should adhere
to
these
parts,
wipe
it off
with
a
cloth
moistened
with pure
alcohol.
WHEN
LUBRICATION
IS
OVER
...
Replace
the
turntable platter
on the
center shaft, then re-set
the
drive belt around
the
motor pulley.
PULL
TURNTABLE PLATTER
UP
WITH POWER STRONG ENOUGH
HOLD BASE PLATE
FAST WITH
ONE
HAND.
