Before turning on your table saw, make sure that the height of the saw blade is no more than 1/2-in. and no less than 1/8-in. above the surface of the workpiece. When setting the height of your table saw, you want to balance the need for safety with effectiveness. The goal is to leave as little exposed blade as possible while still being able to cleanly saw through the wood. When too much of the blade is exposed above the workpiece, friction is increased and the chance of chipping is greater. Also, the higher the blade height, the greater the severity of injury.
