Prior
to
any
attempt
for
dismantling
Tape
Recorder
remember
that:
—
all
the
red
varnish-sealed
screws
required
to
be
removed
or
undone
during
the
disassembly
stage
must
be
secured
again
with
varnish
in
their
position
after
fitting,
—
all
the
lock
washers,
unless
otherwise
stated,
must
be
mounted
so as
to
have
axial
clear-
ance
within
0.1—0.2
mm,
—
clean
working
surfaces
of
the
rubber
elements
add
to
a
better
performance
and
reliability
of
the
mechanical
system.
It
is,
therefore,
advisable
that
they
are
periodically
cleaned
with
the
use
of
extraction
naphta,
