Adjusting the Thread Tension
The Bobbin Winder was designed to give you the
flexibility you need to work with different threads and
bobbins.
Having a proper wind on a bobbin is critical to good
stitching. A bobbin that is wound too loosely will allow
the thread to become tangled or embedded into itself.
A bobbin that is wound too tightly may warp the
bobbin, causing permanent damage and creating a
“bulge” that keeps the bobbin from fitting properly in
the bobbin case.
You may want to adjust the thread tension to accomplish
the best wind for the thread you are using. Use the
following instructions to adjust the thread tension on
the winder to provide a smooth bobbin fill with a firm
surface.
1. Locate the tensioner knob on the front of the bobbin
winder base (Figure 11).
2. Adjust the tension by turning the knob, using one-
quarter turn increments for best results.
3. Turn the tension knob clockwise to tighten the tension.
4. Turn the tension knob counter-clockwise to loosen the
tension.
Thread Tracking Adjustment
The thread tracking adjustment on the Bobbin Winder
is adjusted at the factory for an optimal wind on the
bobbin. However, bobbins can vary slightly, so the
winder was designed to give you the flexibility you need
to work with different threads and bobbins. If the factory
setting does not allow a proper fill, it can be changed
with the simple procedure outlined below.
1. Locate the knob opposite the thread tensioner on the
back side of the bobbin winder base (Figure 12). NOTE:
This isn’t the knob on the thread tensioner itself.
2. Rotate this knob to extend or retract the thread
tensioner on the front for better alignment with the
bobbin.
Turn the knob clockwise to move the thread tensioner
closer to the bobbin winder base.
Turn the knob counter-clockwise to move the
tensioner farther away from the bobbin winder base.
