Question for those of you with Bend Pak 4-post:

The air release button for the safety locks, when I push mine, you can hear air bleeding off from the back of it... is it suppose to do this?

Reason I'm asking, I got an air bottle with mine, and it will store 50psi of air, but will not activate the safety locks... I have to hook up an air line to get them to fire.

It should not bleed out. You should be able to hold it in and hold the locks open as long as you need with no leakage.

Well, double checked everything today... it is all plumbed up correctly, or at least what I can tell from the "not so good" instructions that come with it.

The air is bleeding past the button portion of the valve, the stem. There is no other leaks in the system.

Also, the air lock cylinders take about 10min for them to "bleed down" to where they reset and are able to catch again... is this normal? I would think not.

I think I'm just going to take this air bottle off, and use it the normal way.

That is NOT normal. Either your button is bad, or it is plumbed wrong. Locks should release instantly ( with a good "clank") when you release the button. No air should leak when you push the button.

I'll see if I can sketch up the plumbing arrangement I have and get it posted... then we'll have something for ya'll to look at.

yeah it they should catch and release as fast as you can push the button on and off..

I installed an air bottle, and it had no instructions. draw up how you have it, likely to be the issue.

- The hose at the top of the button at the gauge goes directly to the fitting that is closest to the bottle. (fitting between the bottle and checkvalve)

- The hose out the bottom of the button goes directly to the locks as it did before.

- The hose from the fitting between the two check valves goes directly to the back fitting on the main hydraulic ram.

- The old hose that went from the back of the main hydraulic ram to the side of the hydraulic pump get completely disconnected, and you install a plug in the side of the pump where it was connected.

So the air pressure that was bleeding off the ram into the pump reservoir is now being pushed into the new air bottle.

In the pic you can see I also installed an air hose fitting in the end of the last check valve so that I can attach a hose and fillup the bottle if need be, like say the lift is in the up position a long time and the system leaked down. Quite convenient, but really even if the lift was up and it was empty, you can just run the pump up even though it's max out height wise and it will pressurize the bottle in a couple seconds..

Sounds like it is sticking? Put some air tool lube in the button top? Then run it a few times??

Also make sure the check valves are installed the correct direction.

Here's how mine is plumbed:

scan0001.sized.jpg


Per these instructions:

scan0003.sized.jpg


scan0004.sized.jpg


Per ya'lls posts, and pictures, I have mine put together correctly.

It builds pressure in the bottle, when the lift goes us, and will release the air when the button is pushed, but you can hear air coming through the air valve button stem. And, using the bottle, it has yet to release the locks... I've always had to hook up an air hose to it to release the locks. And, it takes a while for the locks to reset... as soon as all the air is bled from the system, it seems like.

Dang there are instructions now?? The one I got came in a box wrapped in some paper and no clue what to do with it. I had to figure it all out. (was the middle of the night, bp tech was closed)

I do kinda remember one time when I plugged in an air hose (no bottle on an XW) that was regulated down to like 30psi or something it did what you describe. Bleeding air out the button and half opening the locks.. I turned the regulator back up and all was fine.

The ST that the bottle is on will pump to 100 and blow off the safety valve when the lift ran all the way up which by the time the valves closes is 80-90psi.. You probally don't have the psi to open. Try running the lift to the top until the saftey pops and see what pressure you have..

I had to email BP to get the instructions... they did not come with it.

If the lift is all the way down, it will build up pressure to 50psi by the time it gets to the top, the whole time the air valve is hissing. Once you stop, the hissing stops.

I would say a bad button, but it doesn't hiss when you plug in an air hose does it? Seems odd.

Email Jeff for sure. He responds to emails much faster than PM's.

What direction do you have the release button installed? Mine was labeled "IN" and "CYL". I checked it, and I could blow air through it with my mouth in one direction (it would hiss), and the other direction it was closed solid. If I hit the button, it would then let the air through.

I know my button will hiss air out if I push it half way, but if I push it all the way, it seems to seal up and pop the locks. I don't recall it hissing while holding the locks open.. I went up and down with it about 20 times today while working on my car, but the part on the car was a major PITA, so I wasn't paying attention to the release button

yeah, mine is too... I assumed that "IN" was from the air source, and "CYLINDER" went to the locks.

It hisses when partially pushed, and hisses when not pushed. It hisses, also, when pushed, so the full pressure does not go to the locks

These things are Brand-New, state-of-the-art stuff, which is why ket-tek's didn't come with instructions and SVT had to email for them. So you guys are playing on the leading edge of the wave! I received the actual prototype after Jeff and I came up with the idea "simultaneously" :bounce: Of course, the one to manufacture first wins! I'm just happy they are being made and making an already awesome product (lift) that much better!

Today I heard something in the left front wheel of my Galaxie, so I rolled into the shop, lowered the lift , droveon, lifted it up, did an inspection:thumbup: and brought it down - all without having to turn on the compressor!

Bought a new push button air valve, and got it all installed.

Valve solved that problem, but now the push lock fitting on the inlet to the pressure gauge is not holding, so going to get me a compression fitting tomorrow to replace it (don't like those push lock fittings), and see if I can get it to seal.

finally got the air line to seal today.

Lift went up, built up pressure in air bottle, used it to release the locks, and let it back down. First time without using an outside air line.

Woo Hoo!!

Yea it probably shouldn't do that. However I see jeff has contacted you so you got everything worked out.

I had taken all the fittings off the bottle and check valves and resealed them when I got it. Have you tried that yet? Spray some soapy water on all your fittings to find the leak. 45psi in 15 min you should be able to see bubbles with that..

How is everyone's air bottle working? I've had mine for about 2 years now and I've never been able to get it to consistently work. Sometimes it will build up enough pressure and sometimes it doesn't. It seems that it's completely stopped working now.

I bought one, but sent it back and swapped it for something else before I even hooked it up. I wasn't too impressed with it to be honest
