Hey guys I have an old 5f boom that has worked great up until this spring when I first took her out . The lower booms starts off normal speed then gets very slow. Once lower boom is fully extended the upper boom will only go up half way. And vise versa , if I start by raising the upper boom all the way the lower boom won't even come out of rest position.
I only have one small leak left to fix on the lower controls left and right at the handle. Also it has the same problem whether I'm using upper or lower controls. Any help would be greatly appreciated. Thank you
 
Actually, having a pressure gauge somewhere in the hydraulic system is a great idea. Our Terex digger derrick has one built in at the control chair, and it really helps get a feeling for the machine, and diagnosing issues.
