Needle thread Tension too weak
lO. TO REGULATE THE THREAD TENSION
For ordinary stitching, the tension of the upper and needle threads
should be equal so as to lock both threads in the center of the
material (Fig 14). If one tension is stronger than the other, im­
perfect stitching will result. Fine materiols require a light tension,
while heavy materials require more tension to obtain a perfect
stitch.
TO INCREASE the tension, turn the Thumb-Nut (Fig. 15) CLOCK­
WISE.
TO LESSEN the tension, turn the nut in the OPPOSITE DIRECTION,
(when regulating always have the presser
foot down)
As all machines are correctly adjusted be­
fore leaving the factory and readjusted
before the dealer delivers them to you,
the lower tension seldom requires to- be
altered, but, if this becomes necessary,
TIGHTEN the screw in the tension spring
on the outside of the bobbin case for
MORE TENSION, or LOOSEN the screw
slightly for LESSER TENSION (Fig. 16).
