Do you have to take it off to pump up the pressure?

No. With the sprayer in your back, you pump with your left arm and spray with your right.
1003157
No. You just pump it with the lever in you left hand in an up and down motion while spraying with your right hand.
1003158
No, you can leave the sprayer on your back to pump up the pressure. It's very easy.

The black metal arm on your right (with it on your back) is used to pressurize the tank. Just pump it up and down a few times. You will start to fell resistance when it is pressurized. As pressure starts to lessen, just pump it back up.

No, there is a pump on the side that can be used while wearing the sprayer.

I found it so uncomfortable to wear, even wearing a different harness, that I didn't wear it long enough to be able to answer your question. I just used it slung over my shoulder. My husband thought it was very awkward. My other complaint is that it is very hard to store because a tubular metal arm sticks out and cannot be moved, so it takes up a lot of room. But I find the sprayer itself is very adjustable from a fine mist to a steady steam, and I haven't found that to be the case with other sprayers I've owned.

Yes you pump this ball up with your breath but it takes very little effort. The ball comes with a small tube that you breath air into.

No. Mine has pressure reading off 2-3 PSI. Since I know this I just adjust accordingly.

Yes, you do have to pump the handle to keep the pressure up in the sprayer but you will have time between pumps that the spray will come out without pumping.
338654
Yes! You can take it on an off as you please... I have done it several times.

Yes & no. You have to set it on or off, but you can set it so that you do not need to hold it in the on position while you are dispensing fluid.

Yes I believe that the pressure will go up but it may cause the pump to over heat and shorten the life of the pump

Not on the handle but there is a valve that you turn on to use and off when finished..The pressure is easily regulated by that valve...

No - But I don't think you have to worry about over pressurizing with this pump...
467303
Yes, it requires continuous pressure. There is a safety device that prevents it from being on without pressure
89835
No not at all, but more or less full of something will affect the pressure, so you might have to use more or less charges to obtain your desired pressure.
1877902
Yes...you don't want to bleed off pressure unless unless you are replacing seals or valve parts...BUT, you don't want to leave it cocked.
713743
No, it's either on or off. You could pinch the tubing a little to slow down the flow.

You have to pump it to build up the pressure as needed, but then you just press the trigger for misting effect. It works really well, these saved us while waiting in hot, long amusement lines.

Not directly. If you have a pressurized system as soon as there is a demand for water the pump should activate. Otherwise no.
1232474
Yes you will get a little more pressure What those numbers mean is the pump will run until the pressure reaches 60 lbs then shut off and will not come on again until the pressure drop to 40 lbs then comes on and pumps up to 60 again
987964
Yes & we run ours at 40lbs of pressure, & when it builds up it shuts it's self off.
