I am not sure of which pump is on that model but if it is a 2-stage will switch to low flow/high pressure if it doesn't the engine will stall.
The wood flying is not because of the hydraulics by itself it is more due to particular pieces of wood I have had a couple that popped that way.
I found the problem blown oring in the pump works great now ;-)
