Good Lord! Rusted? Frozen? Could be anything, but, there's a manual release valve on the side of the pump/reservoir. Look for a lever or other small part sticking out that you can turn or move somehow. There's another recent post here about this thing - in your case it might have red dots on it?

Anyway, with someone else pulling the safety release FIRST (while the weight is off the bar), try moving/twisting that lever/knob. This manually opens the valve to let hydraulic fluid flow back into the reservoir. It's possible your electrical valve control is not working.

here are some pictures can you tell me what i'm looking for because i can't see anything other then that big black knob.

i had someone get under the trailer while i played with the switch and safty, he said that it looked like maybe the black rubber line was cracked and showed signs of leaking... if the fluid leaked out then what?

if its been sitting that long in the up position, i wouldn't do anything until i cleaned the guide rod real well and lubed it liberally. i would also use liberal amounts of wd-40 on all the cables and pulleys for a day or two before i tried to lower it again, but thats just me

The release lever (manual control) is the rod sticking out of the square box (on the right side in both pictures) which runs parallel to the black tank. This is different than mine, but I understand it "moves" somehow.

I agree with others though, before trying to lower the top I'd get under the trailer and check everything out. You may have some rusted pulleys that are simply not turning. Probably could free them, if this is the case, with penetrating oil.

Edit: the "big black knob" is the filler cap for the reservoir.

The hydraulic fluid flows from the pump to the cylinder that lifts the top thru the metal tube and also returns to the pump thru the same metal tube when you lower the top. The plastic or rubber tube is to return any fluid to the pump that may leak past a worn seal/o-ring on the piston in the cylinder to prevent a liquid lock which would prevent the top from raising if the fluid were trapped behind the piston. In other words you could cut the plastic/rubber tube in two and it would not affect the lifting or lowering of the top. If the manual lowering valve will not lower the top, have someone press the lift switch to the up position, pump running, and open and close the manual valve a quarter turn or so several time to dislodge any obstruction that might be blocking the orfice in the manual valve. Good luck and keep working.

thanks everyone for all the info. I had someone get under the trailer and I kept playing with the switch, the guy under the trailer was tapping the flat piece that is connected to the piston with a hammer ( my feeling was that the piston was just frozen and just needed something to free it) after what seemed like 5 minutes of this the top started down, it is now working fine and I was able to get it moved

It is good to hear that you got it to work. As mentioned above, be sure and very importantly, get everything cleaned and lubed to help prevent any other problems.

thermonieum · 08-24-2011, 02:54 PM

if it has been sitting that long in the up position, have you considered using or selling it???

swbsam · 09-06-2011, 01:37 PM

like many other things that didn't get used that much, i think the saying goes.. use it or loose it... the tralier is going to my X what she does with it is her business....
