Quickjack setup. Down button is not working
I'm at the point in setup where you bleed the system. Up to now, I believe I've done everything as directed. Each Quickjack is up on the rubber blocks and the "Up" button worked as expected. But the "Down" button makes a single, low-level tick sound when I press it and nothing else. Support is not available from them on the weekend, though I did submit a support ticket. Any help appreciated!

I don't have a QJ, but I do have a 2 post lift. On my lift, the lift is lowered with a lever that bleeds off hydraulic fluid. If you QJ does the same thing, it may take some time before it lowers with no weight on it. With no weight on mine, it takes awhile to lower. I don't know much about the QJ. Wish I could help more...

For anyone who may run across this post in the future, I'm only about 150 lbs. I stood on the lower end of each one (the other ends are up on those blocks). They go down slowly and a little jerky at first, but it works
Now to finish setup!

Good deal, the QJs are not hydraulic down, just gravity, so sometimes they will stick a little, usually for me it is at the very bottom of the drop. I think bleeding the air out using the schrader valves helps some too, and I check them periodically and still get air out, even after using them many times now.

I'm doing my initial set up now. I've bled out the air and seem to have a similar issue. I can go up fine and back down fine if I raise it roughly quarter to the first lock out point, but the right side lags. If I go higher than half to lock out I can't get it to go back down. I'm just worried about it not going up and down evenly when I jack up my car. Any suggestions

Are you guys filling the air cylinders with air? They are supposed to be 40-50psi according to the manual. These air cylinders help "push" the Quickjacks to the flat position, you shouldn't need weight (i.e. standing on them) when the air cylinder is adequately filled.

According to my QuickJack manual this is a normal condition when no load is on the jack. It even says to step on it to get it down.

Mine used to go all the way down by themselves until this past summer. We had a heavy rain and water blew into the garage and the rear pivot point of one of the jacks had water around it for a few days. Even though I had kept that kept all the quickjack lube points well oiled, that pivot point rusted and it no longer allows the jack to lower completely under its own weight.

This is where I'm at. Cylinders inflated correctly, absolutely no air in the lines. Still won't go down and I don't get it. I didn't want to proceed with jacking up the car at this point but i dont know what else can be done. Quickjack sent me their "updated" bleeding procedure when i spoke to them last but did nothing.
