Changing the blade on a DeWalt miter saw is a crucial maintenance task to ensure precise and clean cuts. This step-by-step guide will walk you through the process of changing the blade on your DeWalt miter saw safely and efficiently.
Safety Precautions
Before starting the blade replacement process, follow these safety precautions:
- Disconnect power: Unplug the miter saw or remove the battery (for cordless models) to prevent accidental activation.
- Wear safety gear: Use safety gloves to protect your hands from potential injuries.
- Ensure a stable work surface: Place the miter saw on a flat surface to prevent it from moving during the blade replacement process.
Step-by-Step Guide to Changing the Blade
Step 1: Remove the Blade Guard
- Locate the screws securing the blade guard in place.
- Use a screwdriver or Allen wrench (depending on the screw type) to remove the screws and carefully set them aside.
- Gently lift the blade guard and slide it off the blade.
Step 2: Lock the Blade
- Press the spindle lock button, which is typically located near the blade housing or at the back of the saw.
- While holding the spindle lock button, rotate the blade until the spindle lock engages and the blade is unable to move.
Step 3: Remove the Blade Bolt
- Use the provided wrench or an appropriately-sized wrench to remove the blade bolt.
- Turn the wrench clockwise to loosen the bolt, as DeWalt miter saws usually have left-handed threads on the blade bolt.
- Remove the bolt and outer washer, and set them aside.
Step 4: Remove the Old Blade
- Hold the blade securely and carefully lift it off the spindle.
- Take note of the blade’s orientation for proper installation of the new blade.
Step 5: Install the New Blade
- Place the new blade onto the spindle, ensuring the teeth are pointing in the correct direction (refer to the arrow on the blade guard or the saw’s housing for the proper orientation).
- Replace the outer washer and blade bolt.
- While holding the spindle lock button, tighten the blade bolt by turning it counterclockwise.
Step 6: Reinstall the Blade Guard
- Slide the blade guard back into position.
- Reattach the screws to secure the blade guard in place.
