Push the bit into the collet. Then lift it to expose about one-quarter of the shank before tightening the collet nut. This will keep the bit from coming loose in the collet. At least two-thirds of the bit’s shank should be engaged in the router collet.
Cover the bit with a guard whenever possible.
Wear safety glasses and hearing protection.
Use featherboards and push sticks to keep your fingers away from the bit.
Move workpieces from right to left against the fence.
Move workpieces counterclockwise around a piloted bit.
Never position the fence so the workpiece is pushed between it and the bit.
