It’s also essential to work in a well-lit and clutter-free area. Ensure that your workspace is stable so that you don’t risk slipping or knocking into objects while replacing the blade. Be mindful of your fingers and hands when working close to the blade, and never bypass safety mechanisms on the miter saw.
How do I properly install a new blade?
Installing a new blade on the DeWalt DW705 is a straightforward process. Start by ensuring the saw is unplugged and the old blade has been removed. Locate the arbor, place the new blade onto it so that the teeth are facing the right direction (usually toward the front of the saw), and align it with the arbor hole.
Once the blade is positioned correctly, replace the arbor nut and tighten it securely using the wrench. After the blade is installed, give it a gentle spin by hand to ensure it moves freely without any obstruction. Finally, plug the saw back in and perform a test cut on scrap material to confirm that the installation was successful.
