1. Balanced tension: The ideal straight
stitch has threads locked between two
layers of fabric, as illustrated.
2. Upper thread tension is too loose:
The needle thread (upper thread) will
form loops on the wrong side (bottom
side) of the fabric. Tighten the needle
thread tension by rotating the dial to a
higher number.
3. Upper thread tension is too tight:
The bobbin thread (bottom thread) will
appear on the right side (top side) of
the fabric. Loosen the needle thread
tension by rotating the dial to a lower
number.
Useful tips:
Proper setting of tension is important for good sewing.
- There is no single tension setting appropriate for all stitch functions,
thread, or fabric.
- A balanced tension (identical stitches, both top and bottom) is usually
only desirable for straight stitch construction sewing.
- 90% of all sewing should have the thread tension set between "3" and "5".
- For zig-zag stitch patterns, thread tension should generally be less than
for straight stitch sewing.

This product includes 42 kinds of stitches you can use for different purpos-
es. Rotate the Pattern selector dial – primary (22) (1 - 14) and the Pattern
selector dial – secondary (23) (A, B, C) to choose the desired stitch pattern.
CAUTION: Do not turn the Pattern selection dials when the needle is down
into the fabric. Otherwise, the needle may bend or break.

1. After sewing, rotate the Hand wheel (23) counterclockwise (toward you)
to raise the Needle (11) to the highest point. Raise the Presser foot lifter
(33).
2. Pick up the fabric and pull the threads towards the back, so there is at
least 4 inches (10 cm) of loose thread.
NOTE: If you are having difficulties removing the fabric from underneath the
Feed dog (12), push and hold the Thread clamp (17) to the left while pulling
the fabric at the same time. Alternative-
ly, you can rotate the Hand Wheel (23)
counterclockwise (toward you) until you
pull the thread and take out the fabric.

(14) and cut the threads using a down-
ward motion.
Removing the fabric and cutting the threads
Reverse sewing
Reverse sewing is used to secure the
beginning and the end of a seam or to
reinforce places that need extra
strength. The Feed dog's (12) move-
ment reverses to move back the cloth
while sewing to make a locking knot
over the stitches.
- Push and hold down the Reverse
sewing lever (29) to sew in reverse. The
machine will sew in reverse while the
lever is pushed. Release the lever, and
the machine will sew forward again.
Sew a few reverse stitches.
NOTE: Do not add more than 6 reverse
stitches at a time.

Using the seam ripper
The Seam ripper (40) is used to cut the stitches in between fabrics that are
sewn together.
-Gently pull the sewn fabric seam apart, so the stitches are visible and
slightly loosened, then glide the Seam ripper hook in between to cut the
threads.
Buttonhole sewing
1. Turn the Hand wheel (23) counter-
clockwise (toward you) to raise the
Needle (11) to the highest point. Raise
the Presser foot lifter (33).
2. Remove the Presser foot (4) - for
instructions on how to remove the Press-
er foot, refer to the section “Removing or
attaching the Presser foot” on page 20 of
this instruction manual. Attach the
Buttonhole presser foot (36) to the
Presser foot holder (3).
3. Mark the desired length of the buttonhole on the fabric.
4. Place the fabric under the Presser foot (4) and set the Presser foot lifter
(33) down to secure the fabric in place, aligning the distance set on the
presser foot to the length of the marked fabric.
5. Follow the 4-Step Buttonhole sewing sequence (instructions in the next
section of this manual) changing from one step to another with the Pattern
selector dial – primary (22) and the Pattern selector dial – secondary (23).
6. Raise the Needle (11) to the highest point then raise the Presser foot lifter
(33).
7. Pull out the fabric and cut the threads. Cut the buttonhole opening with
the Seam ripper.
NOTE: If you are having difficulties removing the fabric from underneath the
Feed dog (12), push and hold the Thread clamp (17) to the left while pulling
the fabric at the same time. Alternatively, you can rotate the Hand Wheel
(23) counterclockwise (toward you) until you pull the thread and take out

4-Step Buttonhole sewing process
1. Set the pattern to 11A, then sew
at low speed to the marked length.
2. Change the pattern to 12A for
sewing 5-6 stitches at low speed.
3. Change the pattern to 13A at
low speed to the marked length.
4. Change the pattern to 12A for
sewing 5-6 stitches at low speed.
NOTE: When moving from step to step through the buttonhole process, be
sure that the needle is raised before turning the Pattern selector dials to the
next step. Take care not to sew too many stitches in steps 1 and 3 of this
4-step Buttonhole sequence.
Button sewing
1. Rotate the Hand wheel (23)
counterclockwise (toward you) to
raise the needle (11) to the high-
est point. Raise the Presser foot
lifter (33).
2. Attach the Button sewing plate
(35) to the holes on the Needle
plate (5). Attaching the Button
sewing plate stops the fabric and
button from moving up while
sewing.
3. Place the fabric and the button in position on the Button sewing plate
(35). Lower the Presser foot lifter (33) to secure.
4. As the width between the holes on buttons differs, with no thread in the
Needle (11), rotate the Hand wheel (23) counterclockwise (toward you) to
test the stitch width with different zig-zag stitch patterns (11B, 12B, 13B,
14B, 11C, 12C, 13C, 14C) to find the matching width.
5.Thread the upper thread through the needle and then sew 8-10 stitches to
