Tension Discs with Thumb Tabs
If your machine has a thumb tab beneath the tensions discs, make sure you press the thumb tab when you lift the foot to remove your work after sewing. This releases the tension on the top thread, so you can pull the thread freely without putting strain on the needle. This photograph is of the Singer 28K that featured in the machine cleaning video.
Later models have no thumb tab because they were manufactured with a mechanism that automatically released the tension in the top thread when the foot was raised. It took me a long time to get used to the more modern models after years of sewing only on model 28Ks - every time I lifted the foot my right thumb instinctively pressed a non-existent tab.
