Plug lead for RB treadmill?

I have misplaced the plug connection for my treadmill, does anyone know what sort of lead it is, as I cannot remember.
Is it a specialist lead, or would I be able to use a lead off another piece of electrical equipment? I would obviously need to know the power supply level/ampage so I can get
the correct one.

Not sure if it will even run when I do get a plug judging by previous posts!! thanks
