Tension Trouble shooting checklist • Is the presser foot lever down? • Have I oiled my machine? • Is the quilt too tight on the frame? • Is the thread coming off the cone freely? • Has your thread jumped out of the tension discs? • Check your threading. Has anything been missed or has the thread flipped itself around some- thing? • Is the hopping foot too high or too low? • Is your take up rail too high? Did you lower the take up rail after your last quilt? • Do you need to change your needle? • Is your needle in properly? • Top Thread Breaking • Check that your thread is coming off the spool freely and that it is threaded thru the thread guide directly above the spool of thread. • Check to see if the thread has looped itself around the spool pin. • Check to see if the needle is in correctly, with the scarf facing the back of the machine. • Have you recently changed the needle? Is it as high as it will go in the needle bar? Eyelashes • Eyelashes on the back of the quilt can be caused by too little top tension. Turn the thread tension disk clockwise 1/2 turn. • Repeat until stitch quality is good. Remember the upper and lower thread play tug of war with each other. Loose Top Stitch • Is the presser foot lever down? It lowers the hopping foot and engages the tension disk. • Is the bobbin thread inserted in the slot of the bobbin case? • Adjust the tension disk 1/2 turn clockwise. Repeat until stitch quality is good. Quilt Top Puckers • Is your backing fabric stretched too tight? While the backing fabric needs to lie flat and without wrinkles, stretching it too tight can make the quilt top pucker when you release the backing fabric. • The top tension may be too tight. Adjust the tension disc 1/2 turn counter clockwise. Repeat until stitch quality is good. 30
