Step 5: Remove the Old Blade
With the blade bolt removed, gently lift the old blade off the arbor. Pay attention to the orientation; noting how it was placed will help when installing the new blade.
Step 6: Prepare the New Blade
Taking out the replacement blade, inspect it for any damage, such as bent teeth or chips. A flawless blade guarantees a smooth cutting experience.
Also, pay attention to the direction of teeth orientation—the teeth should face in the direction of the table saw’s rotation, which is typically towards you when the saw is running.
Step 7: Install the New Blade
- Position the new blade onto the arbor, making sure it is seated properly.
- Reinsert the washers if they were removed and place the blade bolt through, turning it clockwise to secure it.
Step 8: Tighten the Blade Bolt
While applying slight pressure on the arbor lock button to prevent the blade from rotating, tighten the blade bolt snugly with the wrench.
Step 9: Reattach the Blade Guard
Once the blade is securely in place, reattach the blade guard by following the steps you took to remove it.
Step 10: Final Checks
Before plugging in your saw, it’s essential to check a few things:
- Ensure the blade is properly aligned and free of any obstruction.
- Double-check that the blade guard is securely in place.
Tips for Choosing the Right Blade
Having the right blade for your specific work type can drastically improve your experience and results. Consider these factors:
