I am not exactly sure I believe it is a 1920 Ritter dental chair
I only have the bottom. I have used it for the past 2 decades. It recently started leaking hydraulic oil. Not to sure where from.

1939 Ritter MB dental chair. Motor was humming but when took apart pump and motor turn freely so I think I need to follow the instruction book and open air vent at top of cylinder as well as the pump vent to get the oil to flow. Any ideas. Has not been run in 30 years, Rest of chair is fine.

I have an early 40’s Ritter motor chair model B . I hear motor running when pedal is pushed. How do I check or fill hydraulic oil?
Thank you
