Quick Tatch -how to release hydraulic pressure.

[hottubbrad]

I am trying to replace a rotted hydraulic hose on my quick tatch bucket attachment system. (The one that engages the 2 locking pins on the bottom of the bucket.) My machine is a JD 320E with pilot and keyless start. I am familiar with how to release the pressure for the boom/ aux ect, but the quick tatch seems to have power whether the machine is started or not. Any ideas ?? I am new to quick attach systems.....plenty of experience with tractors though. Thanks

I am guessing there is an accumulator that supplies hydraulic pressure when not running. I would try activating the quick attach system, key ON, but NOT running, both opening and closing until it stops moving (accumulator pressure used up).
