Foot Control
Sewing speed can be varied by the foot
control.
The harder you press on the control,
the faster the machine runs.
WARNING:
While in operation, always keep your eyes on the sewing area, and do not touch
any moving parts such as the thread take-up lever, handwheel or needle.
Always turn off the power switch and unplug from the power supply:
– when leaving the machine unattended.
– when attaching or removing parts.
– when clearning the machine.
Do not place anything on the foot control, otherwise the machine will run intermittently.
Operating Instructions:
The symbol "O" of a switch indicates the "off" position of a switch.
For an appliance with a polarized plug (one blade wider than the other):
To reduce the risk of electrical shock, this plug is intended to fit in a polarized
outlet only one way.
If it 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.
The foot controller Model KD-1902 (USA and Canada market) or KD-2902
(230V,Europe) is used with the sewing machine. Model Sew Simple 113.

•Advantages and uses of free arm
sewing:
— Avoid fabric bunching around the

plackets and waistlines.
— For stitching sleeves, waistbands,
pant legs or any circular garment
area
— For darning socks or mending
knees, elbows or areas of wear in
children's clothes

q
e
w
y
t
* 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 (bottomside) of the fabric.

x Needle 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 moving the dial to a
lower number.
c Needle thread tension is too loose:
The needle thread (top thread) will
appear on the wrong side (bottom
side) of the fabric.......Tighten the
needle thread tension by moving the
dial to a higher number.
14
Changing Needle
CAUTION:
Turn off the power switch when
changing needles.
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 the 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.
