Circular saws are a popular portable power tool because of their ability to make fast, straight-line cuts. Circular saw blades are used to cut different materials, including plywood, hardwood, metal, and plastic. Saw blades should be replaced regularly because they are not long-lasting and can become dull while in use.
It's time to replace your saw blade if your wood starts to burn and saw blades are having difficulty cutting through it. Sharp blades are also required for clean and accurate cuts. Dull saw blades will not provide fine cuts. So, if you want to make clean, accurate cuts for your projects, it's important to sharpen or replace your blades.
Another reason to replace saw blades is that they come in various sizes and forms for various uses. Depending on your task, you'll need to switchblades. Changing saw blades is simple and easy. All you need to know is the process of how to change it?
Follow these five simple steps to replace the old circular saw blade with the new one.
Remove the batteries if the saw is cordless, or unplug the power cord if it is a corded saw. It is to ensure that the blades are changed safely.
Pull the blade guard back and place the saw on a wooden surface. Press the arbor lock button on the top of the blade if the saw has one. The arbor is the pole on which the blade is mounted. Press the blade into the wooden surface if there is no lock button.
The third step is to loosen the arbor nut using a wrench that comes with a saw. To loosen the nut on a direct-drive circular saw, turn the wrench counterclockwise; on a worm drive unit, turn the wrench clockwise.
Remove the old blade by sliding the upper blade guard on the saw. Place the new blade on the arbor of the saw, making sure the saw teeth face the rotational direction. If you're not sure, look at the arrow on the blade guard of the saw. Tight the arbor nut using a wrench. Make sure not to over-tighten the nut as you make cuts with it, the nut tends to tighten even more. So it will be difficult to loosen it the next time you change the saw blade.
Replace the batteries or put the cord into your power outlet once the new blade is installed, and give it a test run to ensure everything is secure and working properly.
Now that you know how to change a circular saw blade, you're ready to get back to work.
