3. Looking at the blade from the guard side of the motor, the blade turns clockwise. That being said by pulling the saw towards you to cut a board can and will cause the saw to clime over the board and come at you unexpectly and could result in the saw hitting or cutting YOU. While the saw will cut in both direction, it is MUCH Safer to push the saw away.
I use a RAS almost daily and can say that the saw cannot climb over the board and come at you. The motor/saw assembly is a fixed distance between the table and the arm, and does not move up and over a board when cutting. If it does that more than one attachment point is loose or not connected, and in that case the saw should not be used anyway. A dull blade, or pulling too fast may cause some resistance which may put an upward pressure on the motor, but in no way will it climb over a board.
What is important is to have a properly set up saw, use an appropriate blade (negative hook), and it being sharp, and feeding into the cut slowly, and use a slow smooth pull.
A push type cutting procedure requires pulling out the saw, setting up the subject piece, and then doing a push cut. I find counteracting the resistance is easier on a pull cut. If a board is wide, there may not be enough room to pull out the saw to start in front of the work.
Getting to know the feel of any tool and its limits may come with their use, and hopefully add to operator safety.
