Default No-lo

Dang! My father has a 1987 hi-lo 22foot fun chaser. He bought it in 1989. It has been stored indoors and has been used very little in the past 22 years. He has had it in the up position for a few years. Yesterday we went to pick it up so that my husband and three kids could enjoy it....but....it wouldn't lower. We looked at the hydraulic res. And it was empty! There was no leak on the floor, so where did it go? Under the trailer, everything looks great. Cables are on straight. We had power. The manual switch wouldn't put the top down either. We are at a loss. My dad lives about 7 hours from us in a very small town in sw Colorado and now the trailer is stuck in the garage since we can't get it down. Where did the fluid go and are there any suggestions as to how we may resolve this issue? Please help! I was sure happy to find this site and any help or advice is sure welcomed.

It sounds like it settled. Try raising it then lowering it. As for where thefluid went....after being stored for that long, it's anybody's guess.

Fill the reservoir to within 2-3" of top when up. Be sure you have a good battery hooked up and not just plugged into 110V. Raise the top a bit. Pull out on the release cable next to the up/down switch and push down while pulling out on the safety release cable. If you get it down be careful towing it with those old tires! Good luck!

It's in the hydraulic cylinder under the trailer. It's in its fully extended position now so all of the fluid is in it and the lines. When the top is down, the cylinder is contracted and the fluid needs a place to go, hence the need for a resevoir.

Does the pump turn on and try to push the top up when you use the switch to lift the top? Can you manually pump the top up enough to unload the safety latch? The top has settled on the safety latch and is preventing them from disengaging when you pull the release cable. It needs to be lifted off of the safety catch by a hair, either by the lift pump or manual pump. You might be slightly low enough on hydraulic fluid that the pump can't lift the top up.

We are unable to get the top to raise up any further than it already is (stuck up)... And nor can we get it to lower. We did fill the res up, but doesn't appear to be going anywhere now that we have fluid in it. Still at a bit of a loss. Appreciate the feedback though!

I'm looking through my owners manual for my 2404TL and on page 23-24, paragraph 7.9, there are some troubleshooting tips on the lift mechanism.

When the top is up the reservoir is and should be almost empty, the fluid is in the hydraulic cylinder, if you fill the reservoir when the top is up and you get the top to go down, the reservoir will over flow and push out a lot of fluid, you may even blow the fill cap off. Don't know if this model has a master switch but it may be in the wrong position. Are you sure the battery is fully charged?

OK, lets diagnose the problem.
What process are you using to raise the hi-lo?
What process are you using to lower it?
Do you hear any noises coming from the pump?
What happens when you pull the safety release cable?

Fireball and pop are right about the fluid. When in the up position the reservoir is almost empty, its in the cylinder. If you have filled it the fluid will be all over the floor when you do get it lowered. You have still not said if the pump runs when you press the switch in the up position. The pump does not run to lower the top. An electronic valve opens when you press the switch to the down position and the weight of the top pushes the fluid back into the reservoir. Did you put a new battery in the rv? It takes a good battery to lift the top and as the previous comments have said you must raise the top to take pressure off of the safety bar before you try to lower the top. Just plugging the rv into house power will not provide enough power to run the pump. Keep working with us here and we will get this fixed. If it would be easier to talk you thru this problem email your phone number and best time to call an I will call you.
