How to Use a Circular Saw How to Use a Circular Saw

Using a circular saw can save you a great deal of time if it becomes necessary to make a lot of cuts. Circular saws can cut a piece of wood that would take 5 to 10 minutes to cut in a matter of seconds. There are some important things to keep in mind when using a circular saw in order to avoid injury and insure that the saw works as well as possible.

Step 1 – Practice Safety

Remember, a circular saw is a dangerous tool if it is not handled properly. When adjusting the circular saw always unplug it first. This will prevent accidental starts which could lead to injuries. Also, whenever using a circular saw you should wear eye protection such as goggles to prevent flying debris from hitting your eyes.

Step 2 - Attach the Blade

If the circular saw does not already have a blade attached then a blade will need to be attached. To do this use the wrench which is supplied with the circular saw to remove the nut holding the blade on. Typically this wrench is found mounted to the guide on the back of the circular saw.

Loosen the nut until you can unthread it by hand. If the nut is extremely tight you may need to use short, sharp motions to dislodge it. Once you have removed the nut, slide the blade on and reattach the nut. Tighten the nut by hand all the way down and then securely fasten it using the wrench. Use short, sharp motions to ensure it is fully secure. This will allow you to tighten it further without spinning the blade.

Step 3 – Position the Blade

Place the circular saw on the wood you will be cutting so the blade buts up against the wood. Loosen the nut on the guide and adjust it until the blade is approximately an eighth of an inch below the wood. You do not want the blade to come out to far below the wood because this increases the odds of kickback and it can cause splintering.

Step 4 – Plug the Circular Saw In

Plug the circular saw into the closest outlet.
Place the circular saw on the wood with the blade approximately one half of an inch from the wood. Position your body in a way in which you are not directly behind the circular saw but you can put a pressure on the blade.

Step 5 – Making the Cut

Depress the trigger and the safety trigger if your circular saw uses one to activate the saw. Move it slowly towards the mark you have made on your wood and cut into the wood just slightly to verify you are level with the line. If it matches the line properly then continue guiding the circular saw. Use a firm, consistent pressure. If the circular saw appears to be having a problem on a location pull it back and then move it forward until the problem area is cut. If the saw does kick back then release the trigger and hold it in place.
