I need to strip down my scubapro S555 second stage to find free flowing cause. Is there an intruction manual out there. I am too far away from a service centre.

May not have exactly your model, but something very very similar. Also, keep in mind, the second stage will free-flow as an "overpressure safety" if the first stage is malfunctioning. Check your intermediate pressure (should be ~150). If you can't do this, try your second stage on another first stage (any brand), and try another second stage on your first.
If it is for sure your second stage, check for proper adjustment of demand lever, bent/damaged demand lever or diaphragm plate, or damaged valve seat.
