Step 7: Secure the Blade with the Spindle Nut
Screw the spindle nut back on while holding the spindle lock button, ensuring it connects firmly but not overtightened. After securing it with your fingers, use the wrench to give it a gentle final twist.
Step 8: Release the Spindle Lock
Release the spindle lock button, allowing the spindle to turn freely. Do a quick visual check to ensure everything is securely tightened and in place.
Step 9: Test the Grinder
Finally, plug in the DeWalt grinder and turn it on for a brief moment to ensure that the blade spins smoothly without wobble or unusual noise.
