When you feed the workpiece through the blade, keep it moving steadily. You have to let the saw, the thickness of the stock, and the hardness of the wood dictate how fast you feed. Burning will tell you you’re feeding too slow — too fast and you’ll see rough saw marks and heavy chipout. But I like to slow down just a bit as the blade starts to exit the cut. This can help avoid chipping along the back edge of the workpiece.
To preserve the clean edge, avoid the temptation to quickly pull the workpiece back along the edge of the saw blade after completing the cut. Instead, slide the workpiece away from the blade before returning. If the workpiece is clamped or a stop block is in place, I’ll turn the saw off rather than risk ruining the cut.
