First time post here. We bought a Jisan hydraulic breaker to replace a Rockram 778 (that was working). Hooked everything up filled with nitrogen. (According to the book it takes a pressure of 60kg/cm2 unsure if that is correct though). Checked pressure on inlet side to be 2800 psi from machine. Removed return hose and have no fluid thru hammer. The controls are ran off the thumb with pressure breaker will move but very slowly and will not repeat. Has anyone else taken one of these hammers apart? Can I even get parts for it if I do? Thank you.
