A circular saw is one of the most convenient power tools available for cutting wood and a variety of other materials. However, they can also be dangerous if not used properly. The following steps provide basic instructions of how to properly and safely use a circular saw.
Step 1: Chose a circular saw that is comfortable for you. There are many different models available ranging from lightweight 5 inch trim saws to heavy 10 inch saws used mainly for industrial work. The saw you use should be of a size that is easy for you to handle and control.
Step 2: Read the instruction manual that comes with your saw. While all circular saws perform the same basic functions, each make and model is designed differently. The instruction manual will explain the various features of your saw and important safety tips.
Step 3: Always wear safety goggles. Circular saws spray a lot of dust and small shavings that can become lodged in eyes. The best goggles wrap around the eyes to prevent foreign objects from entering at any angle.
Step 4: Use the correct size and type of blade and make sure it is properly tightened. The blade should be made specifically for type of material you are cutting. Always use a sharp blade as dull blades will bind and overheat.
Step 5: Be sure the blade guard is in good shape and functioning properly. The blade guard is the most important safety feature on your saw. It should move freely before beginning any cut.
Step 6: Be sure the power cord is in a safe position away from the blade and your feet.
Step 7: Set the depth of the blade to 1/2 of an inch more than the material you are cutting. A proper blade depth will help minimize kick back.
Step 8: Mark the material you are cutting with a straight line. The mark will be your guide for the blade path during the cut.
Step 9: Secure the material you are cutting. Support it high enough so that the blade does not react with anything underneath and clamp the material in a way that prevents movement during the cut.
Step 10: Look down the right hand side of the blade and line it up with your mark before cutting. At the front of your saw there will be guide notches. The right hand notch is the guide for cutting with the blade set in a normal position. Keep your eye on the guide while cutting. This places you in a position for looking along the mark line while out of the way of dust and splinters. Always start the blade before it meets the material and keep both feet planted firmly on the floor.
Step 11: Stand slightly to the side and don't push the saw while cutting. Just gently guide it with a little pressure. Let go of the trigger immediately if the blade binds.
Step 12: Wait for the blade to completely stop turning before setting the saw down.
