Hydraulics on AG equipment generally self purges over time, there is so little air to enter when popping or reconnecting these fittings doubt there is as much as a pinhead of air. Hyd Tank on renters unit used here is Full just above add mark Cold, and OVER Full line when the least bit warmed.

Sometimes machines have a way to bleed pressure off. Maybe with the key on and machine not running toggle hydraulic controls so the valves open.

I would think that new of a machine would have the push in pressure relief on the fittings. If it has both the low flow and high flow couplers try pushing in on the smaller coupling as they are hooked together.

I toggle my NH skid axillary hydraulics with the engine off and the key on every time I disconnect an attachment. I have had no pressure issues since I started doing this a few years ago. I release the pressure on the drives and loader the same way when I shut it down.

Has anyone heard of Waite's Decompression Tool ? It looks really neat and not tooo expensive.
It can be purchased HERE.
It has several options available for the size you need.

You seem to be on the same exact wavelength as I'm on, Tinkerer, because I made contact with a guy who sells these tools via YT. All I would need to go further with this is figure out which tool would work with our plumbing. :rolleyes:

I did all manner of things before borrowing the tools required to crack our lines, Old Iron, including playing with every switch I could think of in the machine. Key on, key off...it just didn't seem to effect the circuit I was working on. Regardless, now that we have the big snowblower attached, I'll try some things after we use it next. It's supposed to snow here in the mountains tonight, so I just might get my chance to try some of these suggestions -- with the snowblower in the loop this time -- sometime tomorrow.

Yes, before you buy anything, at least check to see if you have an issue by correctly unhooking the attachment. As soon as you shut the machine off, compress the aux. pressure release couplers. It should depressurize the Enhanced high flow side. I would then try to reattach the couplers and see how it works.

Once the pressure is left in the line, and the line uncoupled, there is nothing you can do at that point, other than crack the line to release the pressure. The key is to release the pressure prior to removing the line from the machine.

Looks like the couplers he is hooking to are add on and don't have the pressure relief. I'm not familiar with the case machine, are these on a completely different circuit than the other couplers? I also don't see any standard flow couplers like are on other machines.

Tinkerer....I checked out the link you so kindly gave me in Post 44 -- thank you. If you activate the link, you'll see that there are three different size Waite Tools available for flat face hydraulic couplings: 3/8, 1/2 & 3/4. As I don't pretend to be any kind of flat face coupling expert -- in fact, this is my first real in-depth experience with the things -- I'd like to get your thoughts on how to determine the correct size tool for the job at hand? I suspect that it's all about the size of the plumbing [hydraulic line] itself, but, as I just wrote, I'm no expert. Thank you kindly for your help ~ HL :D

Without being there in person I can only give you an online and downloadable guide that is very handy for determining what you have.
Follow the printing instructions that are on the silhouette page. If you can do that, simply hold the printed page under the fittings.
Here is the LINK to the guide.
If that doesn't work for you it would maybe be easier to remove the fittings and take them somewhere that makes hydraulic hoses.
The image below shows the printing instructions.

DP PLATE SERIES - Stucchi USA
I switched to the muitli coupler plates 8 years ago. problem solved. its to bad that the industry is stuck on the crap flat face connectors.
They will conect with up to 3600psi line press.

Like your DP Plate Series, the Stucchi USA Saturn Series depicted in Post 36 is also designed around flat face residual pressure issues. If manufacturers like CASE are going to employ flat face couplers, which, I have to admit, do make far less mess, they really should've consulted with Stucchi before signing the contract with Faster. I realize that some of the couplings on our SV340B are supposed to relive pressure throughout the hydraulic system, but having a big red knob/handle seems a lot more intuitive to this old vet.

TINKERER..... As the sizing chart (below) will indicate, we seem to have 5/8 size flat face couplings on our machine. As our luck would have it, Waite seems to have "skipped over" the 5/8 size flat face couplings.

Flat Face Coupling Size Chart .png

I walked out into the ice and snow with our Mitutoyo digital caliper and measured the male end of the Faster FFH10 coupling hanging on our big snowblower and, yep, the OD was indeed just over 1.061 inches, which is damn near exactly 27 mm. Once again, it looks like we're looking for a way to relieve residual pressure year 'round without breaking the bank. I'd love to buy and install that Saturn Series casting from Stucchi USA, but they don't come cheap. In case anyone with an SV340B wants to look into the Stucchi USA casting shown in Post 36, the model is Saturn Block 15 (5/8" Body) and the order number is 808 800 103....and, if you do install one, please let me know how it works out for you. :)

Handlogger ... I would suggest a tee in a line. Put a ORFS fitting with a cap in the tee. Loosen the cap with a rag to catch the oil. Issue is the tee to fit on the attachment, then a small ORFS fitting & cap ... If the hose on the attachment is NPT, you're golden and the cost will be around $20

Thanks a lot for the suggestion, hosspuller, but all of our plumbing is SAE. If I don't hear back from the Stucchi USA rep that's supposed to be reaching out to us, I'm going to pull the trigger on the high pressure 3-way valve suggested by both Tinkerer and our mechanic (on the very same day). :)

How about a tee with one of these: https://s3.amazonaws.com/onehydraulicsdata/DATASHEETS/SBLV.pdf
