I have a coursemaster 600 that has started to leak hydraulic fluid out of the connection that goes into the hydraulic arm {the brass fitting in the picture is where it has started to leak}. Has anyone had any experience fixing such a leak? .I think it may have some sort of O ring that may have failed not sure . Are these units difficult to prime as when i unscrew the fitting all the fluid will come out.
Any
advice would be appreciated.
