Tension is Poor
Corrective Measure(s)
Lint caught under the tension
spring in the bobbin
• If using short staple threads, inexpensive, or industrial threads,
or coated threads, lint and other material will build up under the
tension spring and begin to lift the spring, reducing the spring’s
ability to compress against the thread. Insert a pin or the corner
of a business card under the spring and clear out the lint. The
bobbin tension will return fairly close to its preset tension. Test the
tension before quilting.
Hand Wheel Won’t Rotate
Corrective Measure(s)
Thread is entangled and caught
in the hook
• There may be a thread lock. With the machine on, use the on-
screen hand wheel to break the thread lock. Quickly move
your finger down and up several times. If this doesn’t solve the
problem, turn the machine off and use the hand wheel at the
back of the machine to resolve the thread lock.
There is a thread lock.
• Carefully rock or turn the hand wheel in direction of motion and
then the other direction until the thread lock breaks free. Once
the hand wheel can be turned freely, remove the thread from
the hook and basket. Now re-oil the hook and make sure the
hand wheel turns freely without the hook hitting the needle. It is
possible for a thread lock to cause a timing problem.
Thread Nests Under Quilt
Corrective Measure(s)
Not enough tension on top
thread
• Check that the machine is threaded correctly. Make certain that
the thread is flossed snugly in place between the two tension
discs. If the machine is threaded correctly, tighten top tension by
rotating the tension knob clockwise. (For more information about
adjusting tension, see Bobbin and Bobbin Tension and Easy-Touch
Tension™ in the Using Your Machine section of this manual.)
Improper threading
• Refer to threading diagram and threading instructions.
Thread Backlash
Corrective Measure(s)
Bobbin thread tangles within
the bobbin case, tangles and
winds onto the hook spindle, or
occasionally forms loops on the
bottom of the quilt
• Make sure the bobbin is in the bobbin case correctly and the
thread is coming out from under the tension spring. The bobbin
should rotate clockwise when the thread is pulled.
Hard to Guide Machine
Corrective Measure(s)
Carriage wheels not centered
on track
• Center the carriage wheels on top of the continuous track. Check
that the machine carriage has not jumped the track.
Thread caught in wheels
• Remove all thread or debris in wheels. Check that the tracks are
free of lint and threads.
