basic oiling will extend the life of your machine
Most machines require you to oil the hook. Read your manufacturer’s manual and follow the instructions. It’s usually very easy. On both of my domestic machines (I have a PFAFF and a Bernina), I have to place a drop of oil at the 6 o’clock position on the hook, before putting the bobbin back into the machine. Super easy!
When to Do it?
Every time I change a bobbin. When you take the bobbin case out of the hook you want to feel that the case is slick. If it isn’t, then you have metal rubbing against metal, and that is not a good thing.
If you haven't used your machine in a while, by all means, oil it before you begin sewing.
Important to do!
It's important to lubricate metal parts. Don't worry, I'm not going to head into your husband's man cave and talk machine shop. But it's important to know that because the bobbin case and the hook are both metal, and when metal rubs against metal it needs to be lubricated, it's that simple. That one drop of oil is all that is needed to keep the lubrication between these 2 vital machine pieces and in the long run will save you money in repair bills.
What oil to use?
Manufacturers have oil that you can purchase, or you can purchase oil at your fabric store. What matters is to lubricate those metal parts.
Important note about oil:
My Long Arm dealer told me that if the oil is not clear, do not use it. When oil gets old it’ll begin to look yellowish or brownish. Once it changes color it is not as effective, and you shouldn’t use it. Just passing this knowledge on to all of you.
My Long Arm requires additional oiling. Again, read your manufacturer’s manual and be sure to know how and when to add oil to your machine.
If you don’t have a manual, you can probably find a group online or email the manufacturer and get that information.
Keeping your machine oiled is an easy and inexpensive way to keep your machine maintained and healthy. And, of course, when you save money on repairs, you have more money for fabric!
