Drawing Up Bobbin Thread

z Raise the presser foot and hold the needle
thread lightly with your left hand.
x Turn the handwheel slowly toward you with
your right hand until the needle goes down and
continue turning the handwheel until the take-
up lever is at its highest position.
Lightly draw up the needle thread forming a
loop of the bobbin thread.
c Pull 10 cm (6˝) of both threads back and under
the presser foot.

Balancing Needle Thread Tension

z Correct tension
The thread tension is adjusted depending
on the sewing materials, layers of fabric and
sewing method.
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.
q Needle thread (Top thread)
w Bobbin thread (Bottom thread)
e Right side (Top side) of fabric
r Wrong side (Bottom side) of fabric
t Thread tension dial
y Setting mark
x Needle thread tension is too tight
When 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
When 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.
