How to add oil in JUKI SC-220. Most spilled when moving machine.

There is a problem with the motor. Check your connections of wiring and such to make sure they are secure. The problem might be the brushes or might be the circuit board to the motor. Look for signs of damage or wear on that main circuit board. If found, replace the board. If the problem is not then resolved, you might contact Juki customer support. This is not an inexpensive machine. https://jukiamericas.com/pages/support

There might be a mechanical problem with your sewing machine to oil to be leaking and it needs to be repaired and the part that stops the oil from spilling out needs to have something sealing it then too to stop oil from leaking out.

Not sure I can help you with the overall problem, however WD40 turns into glue and will stick your machine parts. After using WD40, you should remove it and use regular (good quality) sewing machine oil, or I prefer to skip WD40 and use liquid Tri-Flow Synthetic Lube. It does not dry out over time. You can also add heat from a handheld hairdryer--don't get it too hot if the machine has plastic parts.

Is the motor 110? or 220/3 phase. If the wires are reversed on the motor, it will only run backwards.

Pressure on foot is regulated by the screw on the top of the machine directly above the pressure foot bar. Make sure your lever on back of machine is down, then turn the screw by hand, left for less pressure and to the right for more pressure.

Has anyone adjusted the presser foot inside the machine? That can throw it off or sometimes you need to look under the machine head into the oil pan to make sure there isn't something stuck and holding the pressure up from there.

Is this a new or used machine? Does it have enough oil in the pan?

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.

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.
