IMPORTANT SAFETY
INSTRUCTIONS
When using an electrical appliance, basic safety precautions should always be followed, including the following:
Read all instructions before using this appliance.
DANGER — To reduce the risk of electric shock:
1. An appliance should never be left unattended when plugged in. Always unplug this sewing machine from the electric outlet
immediately after using and before cleaning.
2. Always unplug before replacing a sewing machine bulb. Replace bulb with same type rated 15 Watts.
WARNING — To reduce the risk of burns, fire, electric shock or injury to persons:
1. Do not allow this sewing machine to be used as a toy. Close attention is necessary when this sewing machine is used by or
near children.
2. Use this appliance only for its intended use as described in this owner’s manual. Use only attachments recommended by the
manufacturer as contained in this owner’s manual.
3. Never operate this sewing machine if it has a damaged cord or plug, if it is not working properly, if it has been dropped or
damaged, or dropped into water.
Return this sewing machine to the nearest authorized dealer or service center for examination, repair, electrical or
mechanical adjustment.
4. Never operate the appliance with any air opening blocked. Keep ventilation openings of this sewing machine and foot
controller free from accumulation of lint, dust and loose cloth.
5. Never drop or insert any object into any opening.
6. Do not use outdoors.
7. Do not operate where aerosol (spray) products are being used or where oxygen is being administered.
8. To disconnect, turn all controls to the off (“O”) position, then remove plug from outlet.
9. Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord.
10. Keep fingers away from all moving parts. Special care is required around the sewing machine needle.
11. Always use the proper needle plate. The wrong plate can cause the needle to break.
12. Do not use bent needles.
13. Do not pull or push fabric while stitching. It may deflect the needle, causing it to break.
14. Switch this sewing machine off (“O”) when making any adjustment in the needle area, such as threading the needle, changing
the needle, threading the bobbin, changing the presser foot, and the like.
15. Always unplug this sewing machine from the electrical outlet when removing covers, lubricating, or when making any other
adjustments mentioned in this owner’s manual.

w Foot control for 240V
Operating Instructions:
Foot Controller Model YC-482J or TJC-150 is used
with Sewing Machine Model 661.
This appliance has a polarized plug (one blade wider
than the other). To reduce the risk of electric shock, this
plug is intended to fit in a polarized outlet only one
way. If the plug does not fit in the outlet, reverse the
plug. If it still does not fit, contact a qualified electrician
to install the proper outlet. Do not modify the plug in
any way.

The gap between the needle and the flat surface e should
be consistent.
Never use a bent or blunt needle.
Note: Check your needles frequently for barbed or
blunted points. A damaged needle can cause
permanent snaps or runs in knits, fine silks and

NOTE:
* In general, fine threads and needles are used for sewing thin fabrics, and thicker threads and needles are
used for sewing heavy fabrics.
* Always test thread and needle size on a small piece of fabric which will be used for actual sewing.
* Use the same thread for needle and bobbin.
* When sewing stretch, very fine fabrics and synthetics, use a blue tipped needle.
* The blue tipped needle effectively prevents skipped stitches.

This strong, durable pattern is recommended where both
elasticity and strength are needed to insure comfort and
durability. Use it to reinforce areas such as crotch and
armhole seams. Also, use when constructing items such
as backpacks for extra strength.
The pattern is sewn with two stitches forward and one
stitch backward, forming a seam that does not rip easily.
Garments should be basted for fitting before seaming.

For straight stitch:
The ideal straight stitch will have threads locked between
the two layers of the fabric, as illustrated (magnified to
show detail).
If you look at the top and bottom of the seam, you will
notice that there are no gaps. Each stitch is smooth and
even.
Turn the dial to alter the needle thread tension. The higher
the number, the tighter the tension.
Results depend on:
* stiffness and thickness of the fabric
* number of fabric layers
* type of stitch

SECTION IV UTILITY STITCHES
Zigzag Stitching
Machine setting:
q Stitch selector:
w Presser foot: Zigzag foot A
e Thread tension dial: 2-5
The zigzag stitch is one of the most versatile stitches on
your machine. It can be a utility stitch for sewing on
buttons, buttonholing, hemming, overcasting, mending
and darning.
It can also be used to decorate with trims, appliques and
cutwork or as a decorative stitch.

Overcasting is used on the seam allowance to prevent
fabrics from raveling at raw edges. It can be used to
finish a hem edge. Place the edge of the fabric next to the
black ridge of foot C.

The stitch is excellent for darning and mending tears.
Place your fabric to allow a 1.6 cm (5/8˝) seam.
Trim the extra seam allowance after sewing as illustrated.
Note: Be careful not to cut the stitches.

Use a lightweight fabric (tricot, for example). Fold the
fabric on the bias and stitch on the fold. Allow the needle
to just clear the folded edge to create a shelled edge. You
may need to increase the needle thread tension slightly.
If you sew rows of shell stitches, space the rows at least
5/8˝ (1.5 cm) apart. You can also sew shell stitches on
knits or soft silky woven fabrics, in any direction.

* If thread tension is too loose, tuck will not be
formed. Therefore, increase the tension and set it
between 6 to 8.
