shaft.
The
miniature
ball-bearings
fitted

Unpacking the L 75
When
unpacking
check
for
possible
damage.
The
L.75
is
thoroughly
checked
and
tested
before
leav-
ing
the
factory.
Any
damage
which
may
have
been
caused
during
transport
should
be
reported
imme-
diately
In
this
connection
we
would
like
to
point
out
that
the
upper
part
of
the
knife-edge
balance
has
been
put
into
the
lower
part,
i.
e.
it
is
held
there
only
by
the
weight
of
the
arm.
The
resulting
movement
which
can
be
felt
just
above
the
pedestal
spindle
when
lifting
the
arm,
is
a
normal
and
necessary
feature
of
this
type
of
bearing
and
should
not
be
mistaken
for a fault
or damage.
Preparation for Use
The
L75
is
available
on
a
wooden
base,
or
as
a
build-in
model.
To
avoid
damage
of
the
turntable
spindle
during
transportation,
the
turntable
is
packed
separately
in
a
cardboard
sleeve.
Models
mounted
on
a
wooden
base
are
delivered
fully
assembled
and
can
therefore
be
operated
without
any
difficulty.
The
build-in
model
must
be
assembled
on
the
spot,
and
the
instructions
on
the

should
be
carefully
followed.
