Once the bolt is loose, you can remove it completely. Carefully take out the old blade, making sure to keep your hands clear of the sharp teeth. Be mindful of the direction of the teeth when removing the blade, as this will help you correctly install the new one.
Step 4: Install the New Blade
Hold the new blade by its center hole, ensuring that the teeth are facing forward according to the direction indicated on the blade. Carefully slide the new blade onto the arbor, making sure it sits flush against the saw’s inner blade washer. Secure the blade by tightening the bolt with your wrench or Allen key, turning it clockwise this time.
Step 5: Test and Adjust
With the new blade securely in place, give it a test run before putting it to use. Plug in the saw, hold it firmly, and turn it on briefly to ensure that the blade rotates smoothly and without any wobbling. If you notice any issues or vibrations, double-check that the blade is properly installed and tightened.
Congratulations! You have successfully changed the blade on your Makita circular saw. Now you can get back to your projects with a sharpened cutting tool that will deliver clean and precise results.
