Place the saw upside down on a stable work surface. This position allows for better access to the blade and necessary components. Make sure you’re in a well-lit area for better visibility.
Step 3: Remove the Blade Guard
Inspect the blade guard, which is designed to protect the user from the saw blade. Depending on your specific model, you may need to use a screwdriver to remove the screws holding the guard in place. Be sure to set the screws aside safely so you don’t lose any parts.
Step 4: Lock the Blade
Next, focus on locking the blade to prevent any movement while you are changing it. Most DeWalt circular saws come with a spindle lock. To engage this, press the spindle lock button. This locks the blade in place and prevents it from spinning.
Step 5: Unscrew the Blade Retaining Bolt
Using the Allen wrench, loosen and remove the bolt that holds the blade in place. Turn the bolt counterclockwise to release it. Keep a firm grip on the blade while you do this to prevent it from spinning when the bolt is removed.
Step 6: Remove the Old Blade
Carefully lift the old blade off the saw. Be cautious, as the blade may have sharp edges that can cause injury. Place it on a safe surface, preferably in a designated area for used blades.
Step 7: Install the New Blade
Take your new blade and align it with the mounting hole on the saw. Ensure that the teeth of the blade are facing in the correct direction—typically, the teeth should point in the direction the saw moves during a cut.
Step 8: Secure the Blade
Once the new blade is in position, replace the blade retaining bolt. Be sure to tighten it securely by turning it clockwise with the Allen wrench.
Step 9: Reattach the Blade Guard
Restore the blade guard to its original position, ensuring that it adequately covers the blade. If you had to remove screws in Step 3, now is the time to replace them.
Step 10: Reinsert the Battery and Test
With everything back in place, reattach the battery to the saw. Slowly pull the trigger to test the saw for a few seconds. Listen for any unusual noises, which could indicate that the blade is not installed correctly. If everything sounds normal, you’re good to go!
