Hi Thomas –

I am trying to fill my chair with hydraulic oil, which is actually a 1924 Emil J. Paidar barber chair (I am guessing it’s pretty similar to the Koken). What kind of device should I use to get the oil into the hole? And it is covered by a fill nut from what I can see. Maybe I will post a picture once I am able. Thanks!!

Cheers,
John
