LUBRICATION
Qiling
is
needed
after
every
1,000
hours
of
operation
or
once
a
year
if
the
deck
is
used
infrequently.

Oil
Light,
and
similar
types
of
oil
are
recommended.
Lubrication
is
normally
not
necessary
except
at
the
points
shown.
1.
Place
the
deck
in
a
horizontal
position.
2.
Apply
a
few
drops
of
oil
to
the
respective
spindles
shown,
except
the
capstan
and
the
reel
motors,
Spread
the
oil
evenly
on
the
spindle
surfaces
using
a
cotton
cloth
or
similar
applicator.
3.
For
the
capstan
and
reel
motors,
apply
a
few
drops
to
the
indi-
cated
positions
but
do
not
spread
the
oil.
4.
After
oiling
all
points,
operate
the
deck
fer
1
to
2

is
used
which
references

appropriate
com-

must
be
made.
5.
An
AC
voltmeter
with
an
input
impedance
of
1M
ohms
or
more
must
be
used.
