CLEANING
THE
SHUTTLE
Note:
If
the
machine
turns
hard,
has
a
bind,
or
becomes
noisy,
these
are
all
symptoms
of
thread
tangled
in
the
shuttle
mechanism
or
an
accumulation
of
dust
and
lint
that
is
interfering
with
the
smooth
action
of
the
shuttle.
A
thorough
cleaning
usually
corrects
the
problem.
SHUTTLE
CLEANER

machine
is
fitted

a
shuttle
cleaner
which
removes
accumulated
tint
and
thread
from

clean
and
prevent
jamming.
If
thread
gets
caught
in
shuttle
by
turning
hand
wheel
backwards
or
stitching
without
fabric
in
the
machine,
the
thread
will
break
and
be
swept
out
of
the
shuttle.
The
machine
will
not
jam.
If
machine
becomes
stiff
for
a
moment,

wheel
toward
you
to
free
it.
