    I gave just today purchased jlg 450a lift.
    It has a bad hydraulic leak when trying to activate the lower boom cylinders. I cannot see the source of leak, but it seems to be coming from the area of lower end of bottom boom. The lower two cylinders do not work....probably because all the fluid runs out on the ground when you try to activate them.
    I have not found any "good" drawings to assist a newbie in figuring out how to get to that area.
    I suspect it is a busted hose, but gettingvto it seems to be the 64 dollar question.
    Any help appreciated.
