PROBLEM CAUSE SOLUTION
Thread Breaks cont’d Machine running too fast for the par-
ticular application Reduce speed.
Burr on bobbin case Buff burr with emery and crocus
cloth (available at hardware stores) or
replace bobbin case.
Burr or excessive wear on hook Hooks are not always repairable and
buffing the hook may alter the timing.
Replace the entire hook assembly.
Scratches, needle marks or burrs on
needle plate top, hole, and underside Polish flat surfaces with fine emery,
then crocus cloth. Polish hole with
emery or crocus cord.
Burr on front edge of hook Polish with emery or crocus cloth.
Clean after polishing and re-oil it.
Undetected Thread
Breaks Sensors are not detecting thread
breaks. The machine may be set for a boring
device in MC Parameter 1. Check to
make sure that the Borer parameter is
at Ø.
False Thread Break Sensor wheels are not spinning. Make sure that the thread is wrapped
around the sensor wheel. If so, try
more tension on top tensioner, ¼ to ½
turn.
Thread Break Is
Frayed Burr on eye of needle Replace the needle.
Eye of needle becomes worn (espe-
cially when using metallic thread) Replace the needle. Try an oversized
needle with metallic thread.
Thread guides are worn or burred (es-
pecially when using metallic thread) Polish guides lightly with crocus cord
or replace if badly worn. For a tempo-
rary solution, apply clear nail polish
over the worn spot.
Eye of needle too small Change to a larger needle. When sew-
ing with 40 weight rayon thread, it is
recommended you use a 11/75 or
10/70 size needle.
Thread Frays and
Breaks Weak spot or knots in thread (this
will show up as either a fray or a
clean break) This will show up as an infrequent
break, if so, replace the thread.
Thread Looping The take-up spring adjustment is in-
correct. Increase the take-up spring tension
slightly to eliminate looping on the
top of embroidery.
