I'd like to oil it before I even consider how to thread it. The diagrams are completely illegible (for a novice, anyway).
Any clues? I will say that there are a bunch of holes with red lining, which I'm willing to bet, are the oiling points, but some are different sizes. How many drops am I supposed to put in them? Is that the reservoir marked "oil" near the needle? How much am I supposed to pour in there?
Then I gotta figure out how to thread the damned thing.
The machine shop gave me #22 oil. The manual doesn't specify, but I assume this will work?
Manual oiling is pretty much common sense, so they don't usually put oiling instructions in the operating manual. First of all, just use any good quality sewing machine oil, which is basically just mineral oil. Do not use 3-in-One oil or any petroleum based oil. If you don't use sewing machine oil, it will gum things up and stain fabrics. Secondly, there should be some red paint on the openings that require regular oiling, and the rule of thumb is the bigger the opening the more oil you use. A small hole only needs a couple drops and the larger openings take more. You don't need to soak it, because you should be doing it regularly. Thirdly, make sure you put some oil along side the bobbin case, and take the end cap off the machine and put oil on the wicks at some of the joints that you see behind it.
If there's a reservoir, then the machine is self oiling and all you need to do is keep it filled to the recommended level.
