machine
and
you
will find
the black Allen Head bolt that holds
the
hook
driving shaft.
You may
have
to
turn the hand
wheel to
get
a better view of this bolt.
Loosen
the bolt and
you
will
be able to
physically
turn the shuttle
hook
while
it is in the
machine.
Turn
the shuttle hook
to
the correct setting, Lf 8"
above the
eye
and then
tighten
the bolt.
This
may
take more
than one try.
Tip:
A
quick
way
to check if
your
machine
is
out of time is to lower
the needle. Just
above
the
screw that holds
the needle in
place,
is a hole
that
you
can look into
and
see
the
top of
the
needle.
Loosen
the screw,
then drop the needle
until it
covers
half of the
hole
and try sewing. lf
the machine
sews
properly,
then
you
will have
to advance the
shuttle hook
about
L/32" .lf it
still does not
work,
the
lower
the needle
again, until the
top of the needle
is
even with the
bottom of the
hole, and
then try again. lf
this corrects
the
problem
then
you
will have
to advance
the shuttle hook
about Lf \G".
lf
your
machine
still does
not sew
properly,
then
retime
your
machine
based on the
instructions
above.
These
adjustments may vary
depending
on the
machine. These
instructions
offered
in
this
tutorial may not be
absolute,
because there are
other
factors
that
could come
into
play,
but
are a
good
starting
point.
