Ricoh FF-1 stuck film advance lever

[vlady]

I recently acquired a Ricoh FF-1 with a jammed film advance lever.
It wont budge at all, the spool turns freely how ever. I would appreciate
any help to repair it. I'm looking any service manuals or videos.
Any help would be appreciated. I'm having trouble locating materials.

Is there a battery in it? If not, put in a battery and try to fire the shutter. Also the front needs to be open.

I tried both. Does it need a battery to function?
