Lift arm issue

[JimC]

HI everyone, I searched the site and did not find an answer to my issue so here goes. I have a 763G and it has been running great until today when I blew a line on my 4 in 1 bucket and lost a lot of fluid. I disconnected the 4 in 1 and put the standard bucket on and when I did I could tell that it was low on fluid so I topped it off. After topping off the hydro fluid, the lift arms, tilt and even the drive motors were acting up. I figured it was from the loss of fluid and worked everything slowly and eventually everything started working again, EXCEPT the lift arm. The lift arm will raise up fine, the bucket tilts fine, the machine drives fine, everything works except the lift arm DOWN. When lowering the arms, it will go very slowly, barley moving when under normal operating RPM range. The strange thing is that if I throttle down the RPM to an idle while lowering the lift arms, they will go down much faster. When I raise the RPM the arms slow down again. NOW, with that said, I can hear what seems like one of the operating valves slightly hissing or bleeding off the whole time the machine is running, like a valve stuck partially open as if you were feathering a foot pedals or control. I tried both normal hydro mode and auxiliary modes and it made no difference. Any idea's? Where do I start to trouble shoot? Thanks Jim

Yep

Yep

Any idea's where I should start? Do you guys feel that it is a solenoid? bad valve? I have the books, but they do not give this specific problem in the trouble shooting guide, and nothing listed on a faulty / defective aux. power system, and my copies are hard to even see where the aux. power valves are located. I appreciate the help, Jim

Actually, now that you mention that, I have not put the 4 in 1 back on since I blew the hose. I have it repaired now so I may just hook it back up to see what happens. That is not the answer to the problem though, I would really like to fix the issue if I can.
