To remove an arbor saw blade, the primary step involves loosening the arbor nut that secures the blade to the saw's arbor shaft.
Step-by-Step Guide to Blade Removal
Follow these precise steps to safely and effectively remove your arbor saw blade:
-
Prioritize Safety First
- Always ensure the saw is unplugged from its power source before attempting any maintenance or blade changes. This prevents accidental startup and potential injury.
- Wear appropriate safety gear, such as work gloves, to protect your hands from sharp edges.
-
Access the Blade and Arbor Nut
- Depending on your specific saw model (e.g., table saw, miter saw), you may need to lift a blade guard, remove a throat plate, or adjust the saw's position to gain full access to the blade and its securing nut.
-
Loosen the Arbor Nut
- Place the blade wrench on the nut, ensuring a secure fit. A proper fit prevents slipping, which could damage the nut or cause injury.
- Turn the wrench in the same direction as the blade cuts to loosen the nut. This is a crucial detail for most saw arbors, as the rotation during cutting typically tightens the nut. Turning in the same direction as the blade's cutting action will effectively loosen it.
- Apply firm, steady pressure until the nut begins to turn freely.
-
Remove Components
- Remove the arbor nut and outer washer, setting them aside in a safe place. It's wise to keep these small but essential components together and within easy reach for when you install a new blade.
-
Carefully Extract the Blade
- Once the arbor nut and outer washer are removed, the old blade should be free to lift off the arbor shaft. Handle the blade carefully by its non-cutting edges to avoid accidental cuts.

Practical Insight
Understanding the direction to turn the arbor nut is key to a smooth blade change. The design of many saw arbors incorporates a self-tightening mechanism where the blade's rotation during operation actually works to keep the nut secure. Therefore, to loosen it, you must turn it in the same direction that the blade spins when cutting. If you are unsure of the blade's rotation direction, observe the orientation of the teeth; they always point in the direction of the cut.
