  • Page 20: Optional Accessory: Ruler Base

    Optional Accessory: Ruler Base If you plan to use rulers and templates with the Baby Lock Coronet, you need to purchase the ruler base to give you a large, stable surface on which to rest the ruler or template. The ruler base, rulers, and templates are optional accessories.

  • Page 23: Using Your Machine

    Baby Lock Coronet offers. The Baby Lock Coronet uses the 134 needle system. Note that the needle has a round shank rather than a shank with a flat side like home sewing machines use.
  • Page 24 U CAUTION: Although you can use your fingers to tighten the needle bar clamp screw, we recommend that after finger tightening the screw you use the 2.5 mm Allen wrench to tighten it just a bit more. The Baby Lock Coronet runs at high speeds and this ensures the needle will not loosen while quilting.

     NOTE: You may need to push up the presser bar (see Left Side View, Detail A, item 18) when changing the hopping foot. 3. Fully tighten the screw with the 2.5 mm Allen wrench. | 23 Baby Lock Coronet User Manual...

  • Page 28: Top Thread Tension

    Top Thread Tension One of the joys of quilting with the Baby Lock Coronet is its ability to handle many different types of thread. You can quilt with almost any high-quality thread as long as you first adjust the bobbin tension and then adjust the top tension to suit the thread you’ve chosen.

  • Page 29: Optional Accessory: Quick-Set Tension Kit

    Solution: Loosen the top thread tension by turning the tension knob counterclockwise. If top thread looks like Diagram B Problem: The top thread tension is too loose. Solution: Tighten the top thread tension by turning the tension knob clockwise. | 27 Baby Lock Coronet User Manual...

  • Page 30: Threading The Machine

    Threading the Machine Baby Lock recommends that you select and use only high-quality threads for your quilts. To thread the machine 1. Place thread cone onto spool post ①, insert the thread through the thread-antennae eyelet ② from back to front, continuing to the thread guide ③.
  • Page 31 If thread pulls freely with no tension, rethread the machine, ensuring that the thread is flossed into the tension discs. Â IMPORTANT: The Baby Lock Coronet does not have a presser foot lever or top tension release like a home sewing machine. On a home sewing machine the top tension is released when the presser foot is raised, allowing the thread to come freely out of the machine.

  • Page 32: Quilting With The Baby Lock Coronet

    Quilting With the Baby Lock Coronet Preparing to Quilt 1. Make sure your machine has been cleaned, oiled, has a new needle, and that the tracks on the frame are free from threads or other debris. If the machine isn’t already plugged in, plug it in now.

  • Page 35 When you stop quilting by pressing the Start/Stop button on the handlebars again, the circle turns red, indicating that the needle is not moving. LED lights button: Touch the LED lights button to turn lights on or off. | 33 Baby Lock Coronet User Manual...

  • Page 36: Stitching Modes

    Stitching Modes The Baby Lock Coronet enables you to choose between two modes of stitch regulation (Cruise and Precision) or to choose manual stitching. Manual Stitching Mode When using the manual stitching mode, the length of the stitch is determined by how quickly or slowly you move the machine around the quilt, in combination with the number of stitches per minute (up to 1800) you have selected.
  • Page 37 Machine Quilting Tip: Quilting speed while in stitch-regulation mode It is unlikely that you will move the Baby Lock Coronet across the quilt too fast. However, if you do, it will result in an overspeed condition if the machine can’t maintain stitch regulation.
  • Page 38 (stitches per minute) until you press the stop button on the handlebars. The minimum speed of the needle is dependent upon the stitches-per-minute setting you choose. Baby Lock recommends beginning with a setting of 75. Begin moving the machine to avoid stitching in place for too long.
  • Page 39 Stop button. When you stop moving the machine, the needle pauses. Move the ruler and then begin moving the machine to continue quilting. Precision stitch regulation helps you to avoid bobbles and uneven stitches. | 37 Baby Lock Coronet User Manual...

  • Page 43 Baby Lock retailer. To perform the Motor Speed Sensor Test The Motor Speed Sensor test helps you determine whether or not there is a problem with the Baby Lock Coronet speed sensor.  NOTE: Before performing this test, remove the bobbin case and the top thread.

  • Page 44: Alarms

     NOTE: The most likely cause of a problem is a stitch regulator wheel that is not making consistent contact with the track. Check the spring tension on the sensor assembly on the machine to assure that it will easily return to the fully extended (down) position after being compressed. Also assure that the track is straight with no dips or indentations and that it is clean and free of contamination.
