Hitachi EX200-2 Manual Regulator

Recently,I bought a manual regulator andi nstalled it on my ex200-2 main pump in case of electric failure. There are two stoppers in the kit and i put one in the manual regulator. but i have no idea where to install the rest one. i can't find the servo piston adjust bolt which is a part of the manual kit, as people discussed. Please advise me that in the attached photos where those are to be replaced or assembled. Thank you all for...
