• Check that the power connector is securely plugged into the
back of the machine and the three-prong end is plugged into the
power source.
Corrective Measure(s)
• Make certain the fabric is not rolled too tight, causing the poles to bow.
Check that poles are inserted completely together with the push pins
engaged so bowing won't occur.
• If fabric is beginning to stretch or fray, contact Janome to purchase
replacement leaders.
Corrective Measure(s)
• Inspect for particles and remove any fuzz or debris.
• Look for severe twisting of threads when approximately 12 to 15 inches
has been pulled off, with the ends pinched together. Cotton threads are
particularly susceptible to dry rot or wet rot which makes thread brittle.
Do not use poor quality thread, or thread that is rotted or brittle.
• Balance the tension of the needle thread after ensuring the bobbin
tension is adjusted correctly. (For more information about adjusting
tension, see Bobbin and Bobbin Tension and Easy-Touch Tension™ in the
Using Your Machine section of this manual.)
• Check that the machine is threaded correctly.
• Inspect for accidental double wrapping of thread one thread guides.
• Inspect the thread mast, making sure the eyelets of the mast are
directly over the spools.
• Inspect the vertical positioning of the thread cones. Tipped cones can
dramatically affect thread tension and can cause breakage.
• Change the bobbin. The slightest hesitation of the bobbin rotation can
be the cause of dramatic tension change and thread breakage.
• Change the needle at least once per quilt. Make sure the needle is
installed to the top of the stop hole in the needle bar.
• Replace the needle to one better suited for the thread. Use the proper
size needle. Refer to on-screen chart.
• Move more quickly so stitches don't overlap or build up. When starting
the machine, begin moving immediately. Sewing in one place too long
will cause the thread to break.
• Machine timing needs to be checked. Consult an authorized Janome
technician.
