To attach the foot: First Hold your Walking Foot and raise its Lever. Keep the lever raised and hook the walking foot around the shank / presser bar. Slide the foot up and down until you've lined it up with the hole, so that you can insert the set screw. Put the set screw in and tighten with the screwdriver.

I believe that you are trying to use a foot from a home machine on an industrial machine. I don't really think its possible. If it is possible, you will need to find a snap on presser foot top that will be long enough for the industrial machine. See if you can find a "high shank" top for your foot. They come in two lengths: high shank and low shank. Low shank will NOT work on an industrial machine for sure.
I keep a home machine for making button holes. I bought a button hole maker for my Juki DDL 8700 but by the time I go through all the steps to change it (and the cost of the buttonhole maker was about $80!) it was easier to have an inexpensive used home machine in the closet to get out whenever I needed a buttonhole.
Good Luck!

there could be something wrong with the foot pedal, it may need to be serviced or replaced, or there could be something wrong with the plug where the foot pedal plugs into

Is your needle inserted correctly? Try taking it out and inserting again. Is your bobbing threaded correctly? Try taking it out and re-threading. You might also try cleaning the bobbin area. The only other think I can think of is that you may have the wrong needle in.

check the tension of the belt.

On domestic machines there is a suppressor in the foot control which you can take out and discard because you don't need it, if it is industrial you need to adjust the clutch nuts

machines do not just go out of time. Is the top threaded correctly. did u miss threading thru the take up arm or take up spring change needle too.
