The shaded portions of drawings below represent the fabric enlarged many, many times to
illustrate the lock-stitch principle--how and where both threads should entwine WITHIN fabric
thickness.
Hold finished side of material upward when inspecting stitching.

- To Tighten or Loosen Top Tension
First be sure that Presser Foot is DOWN--resting o
raised, top thread tension is automatically released). To TIGHTEN
needle thread tension turn numbered dial (left) CLOCKWISE. To
relieve tension turn dial counter-clockwise. The higher the number
at which dial is set, the heavier the tension on needle thread. Before
attempting any tension adjustments be doubly sure that machine
is completely and properly threaded and that Presser Foot is DOWN.
If tension adjustment of needle thread does not produce properly
balanced stitching - - only then do you consider adjusting tension on
bobbin case (lower) thread.
To Loosen or Tighten Bobbin Thread Tension —
This adjustment is rarely neccessary unless you have sawing
project calling for very unusual thread in the bobbin - - i,e.
elastic. To adjust tension cn bobbin thread merely turn the
small screw in outer rim of Bobbin Case (right). Turn
screw a little at a time as you pull thread to test tension
on it. Turn screw CLOCKWISE to INCREASE tGHSIOH - - tiiG
otiier way ease it.
