It won't sew. The knob on the side turns very hard.

There are two black plastic locks on each side (shown with errors). Turn them to release the front ring. Pull the ring and whats behind it out then clear your jam.
If the black plastic knobs are too hard to turn then loosen the philips screw that hold them a little then retighten when done.

If it doesn't have thread stuck somewhere or a broken gear, then it is probably still an oiling issue.

Wheel on right side that controls the needle up and down is very tight...

Most likely because your machine has not been serviced (oiled & cleaned) in a long time and the old oil has turned to glue and seized. This is probably the most common problem with mechanical sewing machines. A mechanical sewing machine should be regularly maintained..ie every 40 hours of sewing use or at least every six months when not in use. You may want to take it to a Bernina service technician. Ask for a bottle of Bernina oil for CB hook machines and ask if they will show you how to oil it.

It needs to be serviced. Cleaned and oiled.

Probably best to take it to a service technician.

Could you please clarify? Do you mean the hand wheel? The top one? If it won't turn you likely have a bunch up in the bobbin area.

Do NOT turn it but one way,towards you ONLY,it sound like it's just stuck.Grap something rubberish that will help your grip and try again.Good Luck,don't let this keep you from sewing.
