Depressurizing aux hydraulics

Probably a dumb question but................. When I change attachments, namely the grapple (not a problem with the brush-hog), the A side of the aux hydraulics is difficult or impossible to get disconnected. I either have to wait for it to bleed off in an hour or two or crack one of the fittings which is a PITA and a mess. A friend told me that to get rid of the residual pressure the B sys is pressurized and released then press the one way hyd switch and all should be flat. Any help would be appreciated, I'm just learning how this stuff works and it's only used around the home property. Does the engine need to be running for this process or off? thanks in advance for any help, cd

Does your loader have the 3 quick couplers on a block. If so the just push the couplers in and hold them for a seconf b4 unhooking them.

It just has the two couplers, no case return. When the thing is pressurized I can't get the couplers to move, what am I doing wrong?

I shut mine of then turn the key back on lower the bar, and move the foot pedal back and forth before i unhook and it works most of the time for me. Good luck Brent.
