I recently purchased one and have used it twice. I now have a car up and after disconnecting a hose I find that I can not reconnect it. I even had my muscular neighbor come give it a try. Have any of you had this experience and how did you overcome it.
Question for QuickJack owners
- Thread starter slowpoke
- Start date
I haven't had this problem. Maybe press "Down" to reduce the pressure in the hoses? (To be clear, I have no idea what happens when you do that or if you should - maybe check the manual)
I have disconnected the hoses while the car is up and don't recall having any trouble getting them back together (though there was definitely some pressure)

Hydraulic pressure is stopping you from reconnecting the hoses.
Assuming you have the frame locks engaged, which you should. You can release the pressure by pressing each quick connect center button. Have a rag over fitting so fluid doesnt go everywhere. You should then be able to reconnect each hose.

Use a screwdriver and push in the center of each of the flat faced quick disconnects. You have one that is pressurize. It could be on the jack side or the pump side, or both. Figure out which one is holding pressure and depressurization it.
QuickJack is out untill Tuesday and I need the car down by this evening. I am confused by your bleed valve comment M635. Are you referring to the pressure relief on the power unit? Bleeder on the cylinder? educate me please.

Push and hold the Down button on the remote as you push the quick disconnect fitting into place. That's what QuickJack will tell you to do. That provides a path out for any residual pressure that built up in the system.
Always release the pressurize in the system and hoses. Do this when car is up in locked position or when putting everything away. This is done by pressing the down button for 5 seconds. Do that a few times. Then if you have to disconnect the hoses and reconnect them, they will go together easily.
if the hoses are fully disconnected then push the centers in to relive pressure. If they are still connected then press the down button to relieve pressure.

I'm glad you go it sorted, but I don't understand how this could have happened if you bled the pressure and had the car resting its weight on the locks in the first place.

It’s really common in farm machinery. Normally issue is when you unhook an implement when it’s cold or dark out and trying to hook up when it’s hot or in bright sun light. A little heat can make a lot of pressure in a closed system as the oil expands and has no where to go.

IMO that wasn't an appropriate answer.The guy came on here to ask a question to solve a problem,we all do it.We learn and the forum learns.It could of been a safety issue.I apologize for the rant,every one have a great,safe day.Put your purse down and try both hands.
Do you see the winking emoji? I was kidding
It seems like the bleeder valve and pressing down for a few extra seconds beyond the resting state should avoid that. It sounds like you have a lot more experience with that kind of thing than I do

Don't you know, Comedy is dead. Get with the times. The millennials/generation z are offended about everything now and we HAVE to bend with it or we are brow beated, shamed, canceled, and sever family relationships if we don't comply.

It happens to me a lot when I first go to use the QuickJacks. Yes, I always do at least five seconds after they're fully down. My no-evidence theory is that the slight movement of the frames as you lift them to hang them introduces just enough pressure to make the fittings finicky. It's usually the pump end that refuses to plug in until you hold the down button.
