Don't worry, I have some tips to keep you safe while working. First it's all about basic safety. Make sure you don't wear any loose clothing and that you are wearing safety goggles and hearing protection. Next, make sure that you're using the correct blade for your project. As a general rule of thumb, if you're cutting with the grain, you want a ripping blade. A crosscut blade will cut across the grain. Beyond basic blades, look for specialty blades for different projects like clean cuts, trim, plywood, metal, or concrete. Before you cut, make sure that your blade is clean and that the teeth aren't dull or bent. Using a damaged blade can cause kickback which can injure you. If you adjust your saw height according to the thickness of the wood, you're cutting through. The blades should be set the depth of a saw tooth, pass the bottom of the wood, when you start cutting. Make sure that you stay straight and don't try to force the blade. If you feel it start to bind or hear it screeching, stop cutting, remove the saw and start the cut again. Always watch where your power cord is so that it doesn't interfere with the saw. Also, make sure that the wood is supported on both ends so that there isn't any extra pressure on the blade. Finally, make sure that you let the blade stop spinning before you put down the saw. These easy tips will keep you safe while you work with a circular saw.
