Make sure the saw is on a stable surface. It’s often easiest to perform this task with the saw flat on its base plate.
Step 3: Remove the Guard
The blade guards on a DeWalt circular saw usually have a release mechanism. Press or slide this mechanism to retract the guard out of the way. This gives you clear access to the blade you’re about to replace.
Step 4: Loosen the Blade Bolt
To replace the blade, locate the blade bolt at the center of the blade. You will need to use your wrench (or the blade change tool that comes with many DeWalt saws) to loosen this bolt.
- Press the spindle lock button. This will secure the blade, preventing it from spinning while you loosen the bolt.
- With your tool, rotate the blade bolt counterclockwise until it’s loose enough to remove.
Step 5: Remove the Old Blade
Once the bolt is removed, gently lift the blade off the spindle. Be careful, as even a dull blade can have sharp edges.
Step 6: Install the New Blade
Now it’s time to install the new blade. Follow these sub-steps for a successful installation:
- Make sure the new blade is seated properly on the spindle. The teeth of the blade should be positioned to rotate downward, cutting into the material as you move the saw forward.
- Place the blade bolt back onto the spindle and hand-tighten it for now.
Step 7: Tighten the Blade Bolt
Using your wrench or blade change tool, securely tighten the blade bolt by rotating it clockwise. Ensure that it is snug but do not over-tighten, which might damage the blade or the saw.
Step 8: Reattach the Guard
After securing the blade, return the blade guard to its original position. Ensure that it is functioning properly and can retract when the saw is in use.
Step 9: Reconnect the Power
Once everything is reassembled, it’s time to restore power to your saw. Plug in the corded model or replace the battery in the cordless version.
Final Safety Check
Before you start cutting, it’s essential to do a quick safety check:
- Ensure the blade guard is functioning correctly.
- Check for any loose screws or parts.
- Confirm that the new blade is securely tightened.
Taking the time to ensure that everything is in order can prevent accidents and ensure high-quality cuts.
