HOW TO ADJUST THE WIDTH OF STITCHES
You can adjust the width of stitches by turning the dial (A, Figure 8) in the center of the
machine arm. If the dial is set at 0, the machine will perform straight line stitching. Turn
the dial to the left to increase the width and to commence zigzag sewing.
CAUTION
Stop the machine before rotating the dial (A).

■
HOW TO ADJUST THE LENGTH OF STITCHES
You can adjust the length of stitches by turning the dial inside the pulley (A, Figure 9).
Turn the dial to perform straight line stitching or zigzagging. Turn it to the right to
increase and to the left to decrease the length of stitches.

■ HOW TO ADJUST THE THREAD TENSION
Accurate control of thread tension determines sturdiness and elegance of completed seams.
Tension is accurately balanced when the needle engages the bobbin thread at the center of
the sewing material. To increase thread tension of the needle, turn the screw (A, Figure
10) clockwise and vice versa. If you still cannot get a proper number of stitches, unfasten
the screw (C, Figure 10) and turn the thread tension point (D, Figure 10) to control the
tension of the thread take-up lever spring (A, Figure 11). For more tension, turn the point
(D) in a counterclockwise direction and for less, in a clockwise direction.

HOW TO ADJUST THE PRESSER FOOT PRESSURE
The index screw controls the pressure of the presser foot. (A, Figure 12)
To raise the pressure, turn the screw (A) in a clockwise direction and to reduce the
pressure, either turn the screw counterclockwise or turn it up. Too much pressure can
deform the sewing materials, and too less can result in uneven or skipped stitches.
Normally, low pressure is recommended for the presser foot.

HOW TO INSTALL THE KNEE LIFTER
The knee lifter replaces manual operation of the presser foot.
To install, assemble the knee lifter units as shown in Figure 13.
Then fix it onto the backside of the table with three wooden screws.
