SINGER W12 - Manual (Page 8)

TO COMMENCE WORK
In threading^ the needle and bobbin case respectively, you
should leave an end of thread about two inches in length to each.
Hold the end of the upper thread loosely in the left hand, and
with the right hand gently revolve the hand-wheel until the
needle passes to its lowest point and returns, a loop will be
formed through which the shuttle will pass, and, as the needle
ascends it will draw up the lower or shuttle thread, and the
machine is ready for practical operation.
TO REMOVE V f O R K
Stop the machine with the take-up at its highest point; raise
the presser-foot with the lifter which slackens the upper thread;
then take hold of your work with your left hand and pull it di­
rectly from you, keeping the top thread in the slot of the presser-
foot, which will prevent bending the needle. Now raise the work
and draw the threads into the thread cutter on the presser-bar
and pull downward, which will cut the threads the proper length
to commence work again.
EXPLANATION OF DIFFICULTIES THAT SOMETIMES
OCCUR WITH BEGINNERS
If the upper thread breaks, it may be caused by the needle
not being properly set, or the machine not threaded correctly, or
the upper tension too tight, or the thread uneven and the needle
too small for it, or the needle eye too sharp, or the presser-foot
attached to the machine so that the needle rubs it in passing.
If the under thread breaks, it may be caused by the bobbin
case being improperly threaded, or too much tension upon it, or
by the bobbin being wound too full so that the thread slips over
the ends of the bobbin in the bobbin case.
If the needle breaks, it is more than likely your owii fault
caused by pulling the goods to or from you in such a manner that
the needle strikes the throat plate and is bound to break. The
needle may, however, break in trying to sew extraordinary heavy
seams when the pressure on the presser-foot is not heavy enough.
To create more pressure upon the' goods turn the presser-
bar nut on top of the presser-bar to the right; to decrease the
pressure turn it to the left.
If it makes loop stitches, it is most sure to be caused by too
loose tension both top and bottom.
If the machine skips stitches, the needle is either bent or not
in right position.
If the stitches are not even, it may be caused by the presser-
foot not resting evenly upon the fabric sewed, or by the feed not
being high enough, or by the stitch being too short, or Dy pulling
the cloth or by using too fine a needle with too coarse or uneven
thread.
If the machine should be run without sewing and thread get
in the shuttle race making the machine run heavy, take out
bobbin case and run the machine in the wrong direction; it will
cut the thread out.
Notice.—The leather band should always be tight enough not to slip. If it
slips, or does not force the needle through thick goods, cut off a very short piece
and re-adjust the ends. The belt should not be so tight as to prevent an easy
motion of the machine.
