Subject: Hagie Sprayer Problems


SW MN		We have a 2013 Hagie STS12 that's giving us some air system problems. This morning we started it up and just about when it was all aired up we heard either a pop noise or the air dryer discharge ( not 100% sure because we weren't really paying attention to that at the time) and then all of the bags went flat. We left it run for a while to see if we could hear any air leaks anywhere but couldn't find any. Turned it off and checked some connections, then when we turned it back on the airbags pumped back up but then the relief valves on each bag started going and let the bags back flat again. Now this sprayer just wants to continually pump the airbags up and then let them down again and over and over again.

We've also noticed that the air dryer discharges more than it normally did in the past since the initial deflate. We have replaced both the air regulator on the side of the compressor and the air dryer so far.

Wondering if anyone has seen this before or has any thoughts on what could be causing this.

I have no experience on this but if you replaced governor should you just try to adjust cut in and out pressure some?

Benton County Iowa		I have no idea on the airbag portion of your problem, but if your air dryer is constantly going off. Check the check valve coming off of your air tank. Ours is a 2008. We had that trouble and the brass check valve was bad on the rear tank. I will try to attach a picture of it. We got a replacement from carquest.

Iowa		My 08 did the same thing, ordered a new dryer and it solved the problem. Got if from a truck parts place for.like 150$, JD wanted like 700. I believe this is the one I put on mine. I missed the part where you have already changed the dryer.

Since you've swapped out the air regulator and dryer, maybe check for leaks in the lines and fittings. Also, give those relief valves a once-over. They might be acting up.

SW MN		We did think about the relied valves on top of the bags, but thought it would be kind of odd for all 4 to go bad at the same time.

The other issue I'm having is the 1/4" fitting on the regulator that runs to the tank reservoir won't quit leaking. I've tried two new fittings and it keeps leaking around the release for the hose. So I'm not sure if we're getting too much pressure on that line?

Be sure the signal line from the dryer and the destroke hose are not switched at the governor.

The leak could be part of your short cycle problem, did you cut a little off the hose when you put the new ends on?

I would be adding temporary gauges in the signal line, the destroke line, and the line feeding the air bags so you can actually see what is happening in the system.

I had a truck that short cycled and it turned out to be a longitudinal split in the signal line from the dryer to the governor. I couldn't see or hear it, but the gauges told the story very quickly.

As soon as the dryer popped off, the signal pressure would drop like a rock, signaling the compressor to turn back on prematurely.

Central, IN		Ours had an auto deflate valve at the tank that will drop all 4 bags at once. If you have that mabye it went out.

SW MN		We ended up figuring out the problem today. It was the auto deflate valve on the side of the air reservoir.

Thanks for the help from everyone, it was much appreciated.
