Step-by-Step Guide to Changing the Blade
Now, let’s walk through the process of changing the blade on your 12-inch DeWalt miter saw.
Step 1: Loosen the Blade Bolt
Using the appropriate wrench, locate the blade bolt. It is generally found at the center of the blade. Turn the wrench counterclockwise to loosen the bolt. You may need to hold the blade in place by pressing down on the spindle lock button—this button will lock the blade from rotating.
Step 2: Remove the Old Blade
Once the blade bolt is loosened, carefully remove the bolt and washer. Gently slide the old blade off the arbor. Remember that blades can have sharp edges, so exercise caution during this step.
Step 3: Clean the Arbor and Surrounding Area
Before installing the new blade, take a moment to clean the arbor and surrounding area with a clean cloth. Removing dust and debris can help ensure an even fit and smooth operation of the new blade.
Step 4: Install the New Blade
Place the new blade onto the arbor, ensuring that the teeth are facing the correct direction, which is usually downwards towards the table of the saw. Check that the blade fits snugly onto the arbor.
Step 5: Replace the Washer and Bolt
Once the new blade is in position, place the washer back over the blade and thread the blade bolt. Hand-tighten it initially, ensuring that it feels secure.
Step 6: Tighten the Blade Bolt
With the washer and bolt in position, use the wrench to tighten the blade bolt firmly. Remember to turn it clockwise to ensure it is secure. Holding the spindle lock button will help prevent the blade from rotating while you tighten the bolt.
Step 7: Check Blade Alignment and Safety Features
Once the new blade is secured, check to ensure that it is aligned properly and is free from any wobble. Run your finger around the edge to confirm that there’s no binding or misalignment.
Step 8: Plug in Your Miter Saw
After confirming that the new blade is secure and everything is in order, plug your miter saw back into the power source.
Step 9: Perform a Test Cut
Before diving into your full project, do a test cut on a scrap piece of wood. This step allows you to confirm that the new blade is functioning correctly and cutting accurately.
