boom truck

I have an altec boom truck its on a 1994 f 650. The problem i am having is after i extend the out riggers i cannot get the boom controls to work from the upper controls or the lower controls. I suspect it to be one of the outrigger switches. Each outrigger has one on it. I would like to know how...

So I’m looking at a few bucket trucks. They are davey tree trucks. Most of them have the lrv-55 boom. On the hour meters I’m seeing 3900 or 1600 (06 f750). There is only enough for four digits on the hour meters. So my question is... is this probably 11600 hours and 13900 hours on it?

I have a posi plus boom truck the problem is it won't go up from the joystick or from the lower controls.but if i turn the idle up it works from both controls. Without the idle on it wont go up. Ive never have had to turn the idle on to work the boom ever.

I have a year 2000 boom airlift model AT200AV. How do i access to remove the ribbon hose hold down bar so i can replace the leaking hose inside the upper boom?

im looking at a 92 ford f700 truck has gas 429 and Kubota pony motor. Truck was a municipality truck with 56000 miles used lightly. The issue I have I've been hearing that asplundh booms are junk and unsafe. Anyone have insight on this. Truck did have boom inspection on last yearJune of 2015...

Would any have or know where I could find hydraulics diagram for an LN-50 boom. Chippies ate some of my control lines. Bought new line and replaced them all while I had it down. Now I have no control at the bucket. I must have miss something. Thank you,
