Hello, I was told today that when ripping large boards having the fence in its normal position was unsafe. The explanation being that wood tension could cause the board to be pushed by the fence into the back of the blade. The recommendation therefore, was to pull the fence back so the far end is in line with the blade (and not extended past like in its normal position). I looked up the manual for the saw and it too mentioned this fence position as recommended. I believe it said no more proud of a 45 degree angle from the front of the blade.
I am slightly confused why having the fence in its normal position and using a riving knife if unsafe?
Sorry if this is unclear.
