Hold the needle thread by hand,turn the pulley a circle by right hand.By pulling up the needle thread,the bobbin
thread will be lifted.Combination of bobbin thread and needle thread should be aligned and led back ward.
10. ADJUSTMENT OF THREAD TENSION(Fig.11,Fig.12,Fig.13)
There is virtually no need to adjust the bobbin
thread tension, except for special kind of the
thread, when slight adjustment will be
necessary.
Turning the screw 1 clockwise will increase
the tension of lower thread, otherwise, the tension of lower thread will
decrease (Fig.12).
Needle thread tension should be adjusted in reference to bobbin
thread tension.The needle thread tension can be adjusted by thread
tension adjusting nut.
11. ADJUSTMENT OF THE PRESSURE OF
PRESSER FEET(Fig.14)
The pressure of the presser feet is regulated by the adjusting screw.
To increase the pressure, turn the screw to clockwise, and decrease it, turn the screw to counter-clockwise.

hook point.
b.The center of the needle the hook point is on a line.
c.Gap between the hook point and the side face of needle
should be 0.05mm.
