Table saw arbor nuts should be loosened by turning in which direction relative to the blade rotation?

• A. In the same direction as the blade rotation
• B. In the opposite direction as the blade rotation
• C. While the blade is spinning
• D. Using a torque wrench

Answer: (A)

The direction you loosen the arbor nut is tied to how the blade is mounted and how the threads interact when the blade is turning. When the blade is spinning, applying a turning force in the same direction as the blade’s rotation helps overcome the friction and any locking effect the rotating parts can create, making the nut easier to back off. In practical terms, this means turning the nut in the same sense the blade is rotating. Always unplug the saw and ensure the blade is at rest before changing the blade, and use the proper wrench and safe stance to avoid injury.
