Vicky, The seat should lift up. There might be a screw or two holding it down. Once you get the seat out of the way, In the middle of the seat area, not the cushion, there should be a hole.Add hydrolic oil, non-detergent,(very important) 1/2 cup at a time,Then work the pump several times. Be very careful not to over fill. Email me or call [email protected]. Phone 270304-6943 I would like to have all the info on your chair,Mod #, serial#Or any Number that are under the seat cushion.
