Hello
My Father has an 1983 Ursus 912 that he uses a back forklift on.It works fairly well except the Arms on the Tractor are not working right.Its not possible to set the arms at a desired height.If the lever is any where except fully up the implement eventually just goes to the ground, and when the lever is fully up theres a really loud whining sound,and it actually cuts down the revs a bit,and slows the speed of the spool valves.Now ,i dont know much about the workings of the tractor, but theres a cast iron lever behind the main lever and it seems to affect the arm hydraulics,but as i say, i dont know much about the tractor especially the hydraulic end of things.So, if someone could help me with this,it,and if you could maybe explain what both levers are supposed to do when working right,it would be great.
