Jammed after a friend borrowed it

[$crybe13]

Loaned my Juki MO655 to a friend, and when they brought it back, the handwheel wouldn't budge. It sat in storage for over a year before that, so I'm wondering if it dried out or needs a reset. I've already oiled everything, but I'm still stuck. Are there any workarounds to get it running again?

Try gently turning the handwheel back and forth to loosen it but don't force it, and you can also check if the presser foot or loopers are jammed

I feel like I'm between a rock and a hard place, wanting to get it moving without forcing anything to break. When I'm looking at the loopers, is there something in particular I should look for besides a thread jam? Thanks, btw.

Don't be afraid to take your machine apart!
First, take the presser foot off, then the plate over the loopers. Look to the left to see big knots of thread in the loopers?
If that doesn't help, maybe take the botton of the machine off and see if you see anything below the needle area.
When taking things apart, use little bowls or baggies to put screws in, with a note where they went to.

I am not familiar with your machine, but I have two sergers, and the first thing I would do is move all your dials to zero, then cut your threads and gently pull them out, and don't pull the thread out through your needles! Next, take out the needles (I replace mline every 8 hours of sewing, they can get burrs on them when they are used for too many hours) Then take of the presser foot and then the presser plate, that most likely will be in two pieces, and the back one will need to be unscrewed. Take a strong, small flashlight if you have one and look all around all your dials, in the bottom and the sides, on the inside of your machine where you took off the presser plate(s), and see if you can find any threads that are caught. Look at the disc that turns the flywheel, and make sure there isn't any thread looped around it. If you have some canned air, blow it around the tension dials; they are, at zero, so they will be as loose as you can get them. If this doesn't work, I would put everything back together and take it to a repair person. Since it has been in storage for a year, and you are having this problem, I suggest you take it in for a tune-up. I wish I could help you more!

Wow thank you both for these very thorough instructions. This gives me a much clearer plan and the confidence to open the machine up. I will get my bowls ready for the screws and carefully work through your suggestions probably later.
