At the center of the blade is the arbor bolt that holds the blade in place. Depending on your DeWalt model, this may be covered by a plastic shield, which you will need to remove.
Step 3: Use the Wrench to Loosen the Arbor Bolt
Take the provided wrench and fit it onto the arbor bolt. Turn it counterclockwise to loosen the bolt. You might need to place a piece of wood against the blade to prevent it from spinning while you unscrew the bolt completely.
Step 4: Remove the Old Blade
Once the arbor bolt is completely unscrewed, carefully take off the washer alongside the blade. Gently remove the blade from the arbor. You may need to wiggle it a little, depending on how tightly it was affixed.
Step 5: Clean the Blade Area
Before installing the new blade, take a moment to clean any dust or debris from the blade area and the saw itself. Using a brush or compressed air works great to clear away sawdust that can affect the new blade’s performance.
Step 6: Install the New Blade
Position your new blade onto the arbor, paying attention to the direction of the teeth. Most blades have an arrow indicating the direction the blade should spin. Ensure it faces the right way before proceeding.
Step 7: Replace the Washer and Arbor Bolt
Once the blade is in position, replace the washer on top of the blade followed by the arbor bolt. This is crucial for securing the blade firmly in place.
Step 8: Tighten the Arbor Bolt
Using the wrench, tighten the arbor bolt carefully but firmly by turning it clockwise. Ensure it is snug enough to secure the blade, but avoid overtightening, which can damage the blade or arbor.
Step 9: Reattach the Blade Guard
Now that the new blade is firmly installed, lower the blade guard back into place, ensuring it functions properly. Check for any movements and confirm that it covers the blade entirely when not in use.
Final Checks Before Use
Once the new blade is installed, it’s vital to conduct a few final checks before you plug in your miter saw and start cutting.
1. Check Blade Alignment
Before using the saw, check to ensure that the blade is properly aligned with the fence. Misalignment can lead to inaccurate cuts or kickback.
2. Verify Safety Features
Make sure the safety features are operational, including the blade guard and any other safety switches.
3. Inspect for Unusual Noise
Upon initial use, listen for any abnormal sounds when starting the saw. If you hear anything unusual, disconnect power immediately and recheck the blade installation.
