4. Take your time and make sure you don’t lose any screws you remove, making sure you keep an eye on what screw came from where and the various sizes.
5. Don’t use oil on your machine unless you know that it needs it. Many machines these days don’t require oiling as they are made from different materials/parts than machines that do need a bit of oil.
6. Make sure that the dust and other particles you clean out of your machine are thrown out. A common bit of debris found inside machines are broken needle tips, which can be a hazard.
7. Put the machine back together and test sew to make sure everything is okay. Adjust tensions and rethread as necessary.
8. To prevent any disasters with your machine plug it into a power board with a surge protector. And when travelling with your machine make sure it’s stored in a suitable box/bag/trolley and that your machine’s pressure foot is in the down position.
NOTE: This tip in no way replaces the need for you to have your machine serviced yearly. There are things that a mechanic will check that you cannot do yourself.
