Thanks Drewit. Would the Release begin when the #2 accumulator begins releasing, say for a Swinger ?

The Release triggers into action ALL the Power Accumulators employed. If you are using, per 10-4, a Single Barrel (#2 alone) or Double Barrel Accumulator Combination (#2 and #3) then Release would occur as you describe. Both being low power strokes.

However, I don't believe I have answered your question in the context you mean it. As you refering to Release Motions in 4-D-0 and the Sequenced Release of the Swinger or the normally employed Swinger's Three Barrel (4-2-3) Total Motion Stroke Pattern (in which case the Release of #4 would precede #2)?
