Tip:
Make sure to double-check the compatibility of the new blade with your grinder model to prevent any issues during use.
Step 6: Reattach the Washer and Lock Nut
Position the washer back onto the spindle, then screw the lock nut on top of the washer. Hold the spindle lock button again and turn the lock nut clockwise until it is tight. Be careful not to overtighten, as this may damage the components.
Step 7: Test the Grinder
After completing the installation, plug in the grinder or reinsert the battery for cordless models. Make sure everything is secure. Perform a brief test run to verify that the blade is securely in place and functions properly.
Maintaining Your DeWalt Grinder
