Knee Lifter
The knee lifter is extremely helpful when sewing patchwork, quilting etc, since it allows you to handle the fabric
while your knee controls the presser foot.

q
Attaching the knee lifter
Match the ribs on the knee lifter with the notches in the
knee lifter socket and insert the knee lifter.
q Knee lifter
w Knee lifter socket
Adjusting the knee lifter
The angle of knee lifter can be adjusted to fit your knee.
Loosen the setscrew and slide the angle bar in or out to
adjust the angle of the knee lifter.
Tighten the setscrew to secure the angle bar.
e Setscrew
r Angle bar
e
Using the knee lifter
Push the knee lifter with your knee to easily move the
presser foot up and down.
You can control how high the foot rises by the amount of
knee pressure you exert.
r
NOTE:
Do not touch the knee lifter while stitching, otherwise the
fabric will not be fed smoothly.

Controlling Sewing Speed
Speed control slider
Sewing speed can be varied with the speed control
slider according to your sewing needs.
To increase sewing speed, slide it to the right.
To decrease sewing speed, slide it to the left.
Foot control
Sewing speed is varied by the foot control.
The harder you press down on the foot control, the
faster the machine runs.
The machine runs at the maximum speed set by the
speed control slider when the foot control is being fully
depressed.
Operating Instructions:
The symbol “O” on a switch indicates the “off” position of a switch.
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 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.
* Foot control model TJC-005 is used with sewing machine model 1600P QC.

To Check the Needle
To determine if the needle is defective, place the flat side of
needle on something flat (a needle plate, piece of glass, etc.). The
gap between the needle and the flat surface should be consistent.
Never use a blunt or blunt needle, as it may cause skipped
stitches or thread breakage. Defective needles can ruin the fabric.
Always purchase good quality needles. Change needles often.

Balancing Needle Thread Tension
The needle thread and bobbin thread should interlock
in the center of two layers of the fabric in straight
seams.
Adjusting Bobbin Thread Tension
Test the bobbin thread tension by holding the end of the
bobbin thread and suspending the bobbin case as
illustrated. Then jerk the bobbin case once by flicking
your wrist.
If the thread comes out of the bobbin case continuously, and the bobbin case keeps falling, the bobbin
thread tension is too loose.
Make a slight adjustment by turning the screw clockwise with the small screwdriver.
q To tighten
q
w
If the thread does not come out of the bobbin case at
all, the bobbin thread tension is too tight.

the wrong side of fabric.
Tie the threads together. Trim the remaining
threads.
Turning a Square Corner
Stop the machine a few stitches before the end of
the seam.
Press the up/down needle button a few times until
the needle falls on the end of the seam.
Raise the presser foot.
Pivot the fabric around the needle to change the
sewing direction.
Lower the presser foot and start sewing in a new
direction.
