My machine has 1100 hours on it. I picked up a sweepster brush off eBay. It came from a cnc machine company. The salesman knew nothing about it. The couplers were missing from hoses. Today I installed couplers on it without knowing which was input. I figured it's a 50/50 chance. I also replaced couplers on my machine today. I started up my machine and brush ran backwards, I tried to run forward through switch and nothing happened. I switched backwards to run In Reverse again, when I saw hydraulic fluid spewing from coupler, I shut down machine and disconnected couplers. I started machine to take outside as to not make a mess where my wife parks her car. The arms on machine will go up only, creeps up when hitting pedal down. Tilt will go forward and not backwards. Any ideas?
 
If I turn on the auxillary hydraulics and hold the right side switch in, it puts the engine under a load, but arms and tilt will operate both directions. Im gathering that the aux is stuck on. How do I get the aux turned off?

It sounds like the stems have stuck on, when not used for some time, they can get stuck.
You have two choices here, you can try and repair them, or you can buy new ones.
Lift the cab, look on the left side, there will be a control block. There will be two coils on the top part of the control block, remove the nut and the coil will slide off. You then un-screw the part that the coil goes over, this is the stem. Do not bend it, they are very delicate. If you want to try and repair them, you hold the part with the Orings in a vice and use a spanner on the hex part and it should un-screw. Remove the internal parts, careful not to loose and shims. Unsure the spool in the part with the Orings is free to move in and out. Oil everything up and put it back together.
If that seems like too much effore, you can buy new ones.
Good luck
