For appliances with 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 fully 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.
Foot Control Model YC-482J or TJC-150 is used with Sewing
Machine Models 419S and 423S. (For U.S.A. market only)

Foot control
Sewing speed can be varied by the foot control.
The harder you press on the control, the faster the machine runs.
Caution : Do not place anything on the foot contorol, otherwise
the machine will start advertently.

Presser Foot Lifter
The presser foot lifter raises and lowers your presser foot.
You can raise it about 0.6 cm (1/4") higher than the normal up
position for easy removal of the presser foot or to help you to
place heavy fabric under the foot.

To Attach and Remove the Presser Foot
To remove
Turn the handwheel toward you to raise the needle to its highest
position.
Raise the presser foot.
Press the lever on the back of the foot holder.
The presser foot will drop off.
To attach
Place the presser foot so the pin on the foot lies just under the
groove of the foot holder.
Lower the foot holder to lock the foot in place.
Presser Foot Pressure Adjusting Dial
The Presser foot pressure adjusting dial should be set at 3
3
for regular sewing.
Reduce the pressure to 2 for applique, cutwork, drawnwork,
basting and embroidery for better maneuverability of fabric.
Velours and knit with a lot of stretch may require a 1 setting.

Changing Needle
Raise the needle by turning the handwheel toward you and
lower the presser foot.
Loosen the needle clamp screw by turning it counterclockwise.
Remove the needle from the clamp.
Insert a new needle into the clamp with the flat side away from
you.
When inserting the needle into the clamp, push it up as far as
it will go and tighten the clamp screw firmly with the screwdriver.
* Check your needles frequently for barbed or blunted points.
Snags and runs in knits, fine silks and silk-like fabrics are
permanent and are almost always caused by a damaged
needle.
To check the needle
Place the flat side of the needle on something flat (needle
plate, glass etc.). The clearance between the needle and flat
surface should be consistent. Never use a bent or blunt needle.

Thread and Needle Chart
* 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.
* When sewing very fine fabrics, sew over a piece of paper
to prevent seam puckering.

1 Correct tension
The thread tension is adjusted depending on the
sewing materials, layers of fabric and other sewing
conditions.
* The ideal straight stitch has threads looked between two
layers of fabric, as illustrated (magnifies to show detail).
* For an ideal zigzag stitch, the bobbin thread does not
show on the right side (top side) of the fabric, and the needle
thread shows slightly on the wrong side (bottom side) of
the fabric.
