My needle thread wrap around shuttle hook how do I repair this? on my Brothers CS 8060

Barbara,
Upper thread looping around the shuttle is typically caused by improper threading through the upper tension disks and takeup lever. Check the instruction manual, carefully rethread the top of your machine and make sure the presser foot is in the down position. If the problem continues it may indicate an issue with tension disks. Remove the upper thread, fold a clean piece of fabric and with the presser foot raised to open the tension disks, place the fabric it in the thread path, through the upper tension disks. Lower the presser foot and draw the fabric back and forth to clean any build up of grime and wax from the disks. Lift the presser foot, remove the fabric, rethread and try again.

If the problem persists, you should not need any tools to remove the shuttle to inspect it - sometimes it is necessary to remove the needle plate to lift it out. Check the edges and underside of the plastic shuttle for marks caused by needle strikes - these can catch the thread causing the issue you describe. If there are marks, you may be able to polish them out with fine (600 grit or higher) wet and dry paper. I generally replace them. Also check the tip of the hook for marks - you can often feel these with your fingernail. If they are present, you may need to get a mechanic to polish them out.
