this was a gift from a retiring Dentist which a friend did some work for, I have no idea how it works, it turns on and is rather presentable but again I am no expert. there is a footpedal and multiple tubes, compartments and it seems to have the original owners/users instructions and manuals. I do not know if any parts are missing I am not in the medical field this was a thank you gift on top of a payment for work carried out so please inspect pictures. Update: I have been told the worth of the machine, Open to sensible offers.
