I don't use all three holes, using all three puts too much tension on the thread. I use the first hole and only go through it from the top, use it like a thread guide. The manual says it's for various threads that may need more tension, not for every thread. Threading this way solved many of my top and bobbin thread issues and stopped the needle from becoming unthreaded when using the thread cutter.
