Machine Operations: -Upper and Lower Threading -Winding Thread in the Bobbin -Regulating Length of Stitches

1. Threading the
Sewing Machine

2. Upper Threading
1. Lift the take-up lever to its highest
point.

3. Upper Threading
2. Place the spool of thread on the spool
pin. Pass the thread through the:
a. thread guide
b. tension
c. thread take-up lever
d. thread guide
e. thread guide at the needle clamp
f. needle

4. Upper Threading

5. Upper Threading

6. Lower Threading
1. Wind the thread into the bobbin.
2. Slide the plate which covers the lower
parts.
3. Hold the bobbin so that thread unwinds.
Insert the bobbin case.

7. Lower Threading
4. Pull the thread into notch. Draw it under
tension spring and into the slot. Unwind
about 10 cm(4in).
5. Hold the bobbin case by it latch. Insert it
at the spindle of the shuttle’s body so
that the finger enters the notch at the top
of the shuttle. Release the latch. Press
the bobbin case until it click in place.

8. Lower Threading
6. Slide the plate back to its original
position.
7. Hold the end of the needle thread lightly
with your hand. Turn the balance wheel
slowly toward you so that the needle
enters the throat plate.

9. Lower Threading
8. Continue turning the balance wheel by
holding the needle thread. Until the
needle rises again, bring up the bobbin
thread in a loop.
9. Unloop the thread with your fingers.
10.Position both the needle and bobbin
thread under the presser foot.

10. Winding Thread in the Bobbin
• Loosen the stop motion screw. This stops
the needle from moving.

11. Winding Thread in the Bobbin
1. Start by placing your spool of thread on
the machine, and threading the (first) top
thread guide.

12. Winding Thread in the Bobbin
2. Then look for another thread guide that is
out of place, down lower or off to another
side, and wrap your thread around it
once.

13. Winding Thread in the Bobbin
3. Then take a look at your bobbin. There
should be a tiny little hole on the side for
you to put your thread through. Thread
from the inside of the bobbin, out, so your
thread sticks out the side an inch or two.

14. Winding Thread in the Bobbin
4. With your thread guides still threaded,
look for a little metal shank at the top of
your machine somewhere. It will look like
this:

15. Winding Thread in the Bobbin
5. Snap your bobbin onto it, and push the
shank and bobbin over to the side with
the thread stopper (round white thing).

16. Winding Thread in the Bobbin
6. Press your foot down on the pedal and
begin winding the thread onto the bobbin!
You'll want to hold on to your thread at
the very first, to make sure it doesn't slip
out of the hole.

17. Winding Thread in the Bobbin
7. Run the machine until the bobbin is full.

18. • To insert and thread your bobbin into your
machine, first slide off, or fold down the
section in the front of the bottom of your
machine.
•

19. • Underneath is where you'll find the bobbin
case:

20. • Pull out the bobbin case, using the hinged
flap in the front.

22. Regulating the Length of Stitches
Stitch regulator controls the length of
stitches and reverses sewing (backward
and forward).
1. Hold the lever between your thumb and
pointer.

23. Regulating the Length of Stitches
2. Position the lever opposite the
desired number of stitches – the
bigger the number, the shorter the
stitches and vice versa.

25. Regulating the Length of Stitches
3. Move the stitch regulator up to the level
of the lever.
4. Tighten the screw. This prevents the
lever from moving backward down
causing a change on the length of
stitches.
