Three-hole guide near the Tension Assembly
The three-hole thread guide near the tension assembly provides pre-tension to your thread and also helps manage
“thread twist” before your thread enters the tension disks on the tensioner.
Occasionally you should check the three-hole guide’s angle. It should point down to “8:00” if you imagine the lower hole
as the hands on a clock. This position also helps ensure the thread travels through the tension disks correctly.
It’s okay to experiment with the thread path next to the tension assembly if your thread requires more pre-
tension, or if the thread appears to twist too much, causing tangling or looping around the needle. Photos
above show some optional thread paths through the three-hole guide next to the tension assembly.
Be sure to use the bottom-most hole in the guide (illustrated with arrows above). This last hole ensures that
your thread stays deeply between the tension disks and does not slide in and out as you sew.

Pull the thread between the tension control disks and over the check spring as shown. Hold on to the
thread just before it enters the tension disks and pull on the remaining tail firmly to be sure the thread
is seated completely between the tension disks.

If your stitch quality appears to have changed, such as loops of thread on the quilt surface, this
is one of the first places to check. The thread must be completely seated between the two
tension disks for proper operation.
