PROBLEM CAUSE SOLUTION
NOTE: Whenever you break a needle, make sure you find all parts of it before you continue sewing. A
needle point that gets lodged in the hook assembly of the machine can cause the machine to bind up and
stop running, possibly causing serious damage. Also check for burrs on the hook if parts of the needle are
found under the needle plate.
Stitches Are Not Being
Formed
Bobbin is empty Replace with full bobbin.
Not enough bobbin thread pulled out
of bobbin case
There should be at least three (3)
inches of thread hanging from the
bobbin case when it is replaced.
Needle inserted improperly Make sure the needle is inserted all
the way into the needle bar and the
long groove is in front. Make sure the
needle clamp crew is tight.
Timing is off Re-time the hook.
Broken hook point Replace the entire hook assembly.
