Will it hold vacuum (or pressure) until manually released?

Yes. It will hold both vacuum and pressure. Use it to test carburetor seals on chain saws and cutoff saws

Haven't had need for it yet. If I was guessing I would say yes if its anything like Mityvac.

It hold pressure at lower psi but start to loose pressure when target pressure is reach and pumping stop. It also takes a lot of pumping to reach the desire pressure.

Actually it works well, I didn't think much of it at first. The direction with it are a bit vague but after I figured it out it does what it is made to do pretty good. Yes, mine will hold the vacuum and not leak down when I put my finger over the end of the tubing. I think that the attachments are some what of a problem because they didn't fit on my Chevy brake bleeder really tight. I thought it took a lot of pumping also at first but like I said after I figured it out not so much pumping.

It does not have a pressure release valve. You have to dispense the contents before opening. Or you can just tilt bottle until the pick up is not in liquid. Other than that you have to wait until bottle is empty and then release pressure by holding wand open until all the air is released.

It does not come with a vac release or a vac gauge. I bought the guage separately. It uses a different measurement than PSI.

Yes, the hose keeps tugging back when your pulling it out. you have to hold it while vacuuming. not fun

I'd love to be able to help u but I haven't used it yet. I would guess it maybe vacuum holding it on. Not to b funny but have u looked in the owners manual? It may have some helpful hints.

Maybe you can try to release the vacuum in there first by reversing the valve to "discharge" ....

The vacuum pump I use has a pressure gauge on it or you can run it through your gauges.

Yes, it can, and that is how I ended up with a broken unit. It is supposed to work, but when I applied vacuum, the gauge topped out and has not moved since. (high side). I was able to pull a vacuum and do the work. I think I got a bad unit. Still, all together, it cost less to buy this and have it go bad than to have the A/C work done in the first place.

The pump has a pressure switch that will automatically turn it on and off as needed to maintain vacuum.

Yes, you do have to hold the on/off switch to keep the vacuum running. For me, this is not a problem. I mainly use the Makita for spot cleaning. I rarely need to operate it in one place for more than 15-20 seconds.

Yes, just push the button & monitor the pressure until it gets back to where you want it.

No - you pump the knob on the cover about 10 - 20 times and then after a day you pump more because it does not hold the vacuum.

Yes. it will take a minute or two to pump up from minimum pressure, but it should be no problem.

No you do not have to hold the button down while vacuuming. Has a lot of power.

I "think" you must hold down all of the time.....I do.....remember the vacuum is for quick pickups or short vacuuming.

It will if your pump has sufficient suction. Your pump does the vacuum job.

I don't believe so, they have a specially designed valve thing for the vacuuming. U just press on the lid and it goes out the mechanism. I don't think this would work with an other devices. The valve thing has a 'skin' over it to lock air from coming back in, I don't see how you could bypass that.
