So - do you block it when you're camping? Or do you trust your cables enough?
I'm thinking that maybe I should just replace them, for the peace of mind if nothing else.
I did make the adjustments in small increments, and ran it up and down a few times in the process (maybe 8 - 10 times)...but I anticipate it will still need to shake itself out in the next few raisings/lowerings.
Also - regarding the adjustment - after I'd made my adjustments, I noticed that it took a bit longer to hear the safety bar "latch". Part of that I'm attributing to my hydraulic pump being low on fluid - but perhaps part of it is the top going too far up. According to my meager assessment, it's not going quite far enough up just yet, but it's really, really close.
There are detailed instructions in how to area on how to adjust the cables. please note, the battery (I know MINE
does) really gets used hard each time I go up. Like I have said, 30 foot long, 5th wheel. so even my brand new battery (just this past week) will run mine up and down about 4 (for this discussion sake maybe more times) before battery is dead. So, each time UP is slower
than previous time, even if trickle charging while plugged in.
so, time it takes to take the cables to pull all 4 corners (about 14" inches of hydraulic cylinder travel on mine) changes anytime the battery hasnt had time to be fully recharged and ready to go up... BUT if your top is up before the catch is catching, you MIGHT HAVE adjusted the wrong cables, possibly. maybe the high side was too high, instead of the low side being too low and now your seals are hitting harder and pulling harder on the cables to reach the safety latch?

If that's the case, then to block the top while camping would be unnecessary overkill, right?
you know the difference between a salesman and a politician? the politician knows damn well that he is lying to you. the salesman (unless educated hilo's about the lift process & parts) has no clue. the "safety catch is to keep the hydraulic system from slowly letting itself down, as most hydraulic systems do. this is why you dont work on a car without jack stands, at least 50% of why, the other is of course in case you knock car off jack.
FWIW: This is no different than a popup tent trailer, except my tent trailer used a hand cranking winch to pull on a block, with all 4 cables attached to it tight, where as Hilo uses a hydraulic cylinder to move a plate that moves the cables.
At any rate, there is/are 2 possible failures present at all times even on a popup, without the safety latch. One is hydraulic cylinder getting a leak, popping a line, or in the popup: the singe cable to winch breaks, & whole top comes down, or any one of the 4 cables on the plate that the winch pulled on, failes, meaning usually a corner might drop a little bit.
My coleman even has a safety like the hilo does, when you winched top all the way up, the plate with 4 cables caught just like our bar does at the hydraulic cylinder. you had to pull a lever to start lowering the top with the same winch.
Look under there while you are looking at the cables, you will see the rod that the little loop of cable lifts on when lowering, which hooks the cylinder's big plate with the pullys on it, when fully extended... It is on TOP above the cylinder. again, It ONLY takes pressure off the pump/cylinder, because Hydraulics, they "WILL" settle over time, they just do, more so when using a powered pump. Even well built "good" bottle jacks will settle in a day (camping is usually more than a day).
this means that the cables are holding everything when unit's roof is anything but all the way down at rest on the little supports.
that is reason #1 to check these cables (maintenance). I believe it is reason #1 to not store with the roof up without support. WHen I camp, I can put the same boards in to hold it up, I dont. I trust stuff, especially that I know the following:
*** Everything mechanical has a finite number of hours, or uses before it fails. So, you subtract hours each and every hour the top is held up with cables. there might be a thousands of hours by average of over thousands of our cables, assuming they are prisitinely maintained, but there is NOT an exception, at some point in time/life cycles! --> they will fail
So I LIKE TO SAVE UP all my hours until failure in a little mythical "bag", by using supports when stored at home. It is that simple but of truth & logic, is why I do it. why waste the cable's usefull life while storing my camper, where I want it up so I dont have to run batter down raising it up and down each time I need to get in it.
