new here,i,ve gotten lots of info so far from reading posts.however i havent seen a post that helps me out with this.its a DOLL fluid power product made by arrow machine inc.its a simple control,just a resevoir with a handle that you spin to raise and lower the tilt.sounds simple anyway.but it dont work.before i trash it and spend money on a new one,i'd like to be be sure its bad.i've filled it with hydro fliud,removed the hose and spin it round and round.nothing,not even a dribble.<br /><br /> i know nothing about its condition prior to my ownership .i bought a unfinshed project boat.so i get the fun job of putting it back together.not knowing if it worked before.<br /><br /> found nothing in manuals on it,nothing on line about it,so has anyone ever had one or worked on one.its a sealed unit so there no tearing it apart that i can see.<br /><br /> again its a doll fluid power product,made by arrow machine inc., model # s-p500
