I recently picked up a MH 50 for a friend and we are getting it ready for use. The previous owner had it set up so that it had a single hose and coupler for a remote cylinder off of the second lever control on the hydraulic valve. I added the second hose and coupler in where the second port was plugged so he could run a 2 way cylinder. Now I can get pressure on one side, but not the other, like the valve is set up to be only single acting. I do see some adjustment screws but not sure if they will change that or not. I ordered a book for it, but sadly it isn't here yet. Could use a little help!! Thanks.
