The knee lifter first started to tighten up. Now it is almost impossible to use it. I have to push it so hard, it is painful. It lifts up the foot, but not all the way.
I imagine that it is the mechanical knee lift that you actually lift with your knee? Sometimes the screw that holds the knee lift rod comes loose a little and starts to slide in the holder. Sit on the floor where you can see the underneath of your table and use a wrench or vise grip to loosen the bracket that holds your knee lift bar with the pad on it. Move the bar to the left and retighten the screw and I think you will be ok. Sometimes if there is too much oil in your pan or you have moved the machine and some of the oil spilled out, a little oil gets out of the pan onto the bar and makes it start to slip. If that doesn't work we'll try something else.

MAKE SURE YOU HAVE THE RIGHT NEEDLE FOR THE THREAD YOU ARE USING, AND THAT THE SAME THREAD IS ALSO IN THE BOBBIN. CHECK UPPER TENSION, BY PULLING SLIGHTLY, IF IT'S TIGHT, LOOSEN THE UPPER TENSION.YOUR THREAD MAY BE THE WRONG SIZE OR TYPE FOR THE SPEED YOUR SEWING., and the needle your are using( sorry about the caps lock)

Sounds like as the machine builds up friction from extended use, some vital part is lacking lubrication and is seizing up. A good service person will remove ALL of the covers and thoroughly air clean and oil every moving part. Sometimes these dry points are hard to find and patience is required.
You can get a sewing machine oiler with a long applicator and put a drop of oil on anything that moves, but over oiling can be messy.

Regular sewing machine needles. Choose the needle type and size according to the type fabric or thread being used.
