Step-by-Step Guide: Changing Your Ridgid Table Saw Blade

Follow these steps carefully for a safe and successful Ridgid table saw blade replacement.

Step 1: Disconnecting Power and Preparing the Saw

1. Unplug the Saw: This is the most important step! Ensure the saw is completely disconnected from the power source.
2. Raise the Blade: Raise the blade to its maximum height. This will provide more clearance for removing and installing the blade.
3. Remove the Throat Plate: The throat plate is the insert around the blade. Depending on your model, it may lift out or require loosening a screw.
4. Clear Debris: Use a brush or vacuum to remove any sawdust or debris around the blade and arbor.

Step 2: Removing the Blade Guard and Riving Knife

1. Blade Guard Removal: Most Ridgid table saws have a blade guard that needs to be removed. The removal process varies depending on the model, but typically involves loosening a knob or lever and lifting the guard off.
2. Riving Knife Removal: The riving knife prevents kickback. It usually slides out or pivots after loosening a locking mechanism. Note: Some models may have an integrated blade guard and riving knife, requiring you to remove them as a single unit.

Table: Typical Blade Guard and Riving Knife Removal Methods

Component	Removal Method	Notes
Blade Guard	Loosen knob/lever, lift off.	Check your specific model’s instructions.
Riving Knife	Slide out/pivot after loosening locking mechanism.	May be integrated with the blade guard on some models.

Step 3: Locking the Arbor and Loosening the Arbor Nut

1. Locate the Arbor Lock: The arbor lock is a mechanism that prevents the blade from spinning while you loosen the nut. It’s usually a button or lever located on the saw’s housing, near the blade.
2. Engage the Arbor Lock: Press and hold the arbor lock. You may need to rotate the blade slightly until the lock engages. You’ll feel or hear it click into place.
3. Loosen the Arbor Nut: Use the correct size table saw blade wrench. Important: The arbor nut on most table saws has a left-hand thread. This means you turn it clockwise to loosen it, opposite of what you’d expect. Apply firm, steady pressure. If the nut is stuck, avoid using excessive force that could damage the saw. Try using a penetrating oil and let it sit for a few minutes.
4. Remove the Arbor Nut and Outer Flange: Once the nut is loose, fully unscrew it and remove the outer flange (the washer-like piece). Keep these parts in a safe place.

Step 4: Removing the Old Blade

1. Carefully Remove the Blade: With the arbor nut and outer flange removed, carefully lift the old blade off the arbor. Be mindful of the blade’s sharp teeth.
2. Inspect the Arbor and Flanges: Check the arbor and flanges for any damage, such as rust, burrs, or warping. Clean them with a soft cloth to remove any debris.

Step 5: Installing the New Blade

1. Mount the New Blade: Place the new blade onto the arbor, ensuring it sits flush against the inner flange. Make sure the blade’s teeth are pointing in the correct direction (usually forward, in the direction of the saw’s rotation). An arrow on the blade indicates the proper rotation direction.
2. Reinstall the Outer Flange and Arbor Nut: Place the outer flange back onto the arbor, followed by the arbor nut.
3. Tighten the Arbor Nut: Engage the arbor lock again and tighten the arbor nut counter-clockwise (remember it’s a left-hand thread) until it’s snug. Do not overtighten. It should be firm, but not excessively tight.
4. Release the Arbor Lock: Release the arbor lock and spin the blade by hand to ensure it rotates freely.

Step 6: Reinstalling the Riving Knife and Blade Guard

1. Reinstall the Riving Knife: Slide or pivot the riving knife back into its position and secure it according to your saw’s instructions. Make sure it’s properly aligned with the blade.
2. Reinstall the Blade Guard: Reattach the blade guard, ensuring it’s securely in place. The blade guard is a critical safety feature, so make sure it’s functioning correctly.

Step 7: Reinstalling the Throat Plate and Testing

1. Reinstall the Throat Plate: Place the throat plate back into its slot and secure it.
2. Plug in the Saw: Plug the saw back into the power outlet.
3. Test the Saw: Turn on the saw and let it run for a few seconds to ensure the blade is running smoothly and there are no unusual vibrations or noises.
4. Make a Test Cut: Use a piece of scrap wood to make a test cut. Check the cut quality and ensure the blade is cutting cleanly and accurately.

Step 8: Aligning the Table Saw Blade (If Necessary)

After changing the blade, it’s a good practice to check the blade alignment. This ensures your cuts are accurate and prevents binding.

1. Check Blade Parallelism: Use a reliable straight edge or a dial indicator to measure the distance between the blade and the miter slot at the front and back of the blade. The distance should be the same.
2. Adjust Trunnion (If Necessary): If the blade isn’t parallel, you’ll need to adjust the trunnion, which is the mechanism that holds the motor and blade assembly. The adjustment process varies depending on your Ridgid table saw model, so consult your owner’s manual. Usually, it involves loosening some bolts and shifting the trunnion slightly until the blade is parallel.
3. Re-Check and Fine-Tune: After making adjustments, re-check the blade parallelism and fine-tune as needed.

Table: Blade Alignment Troubleshooting

Issue	Possible Cause	Solution
Blade not parallel	Trunnion out of alignment	Adjust trunnion according to owner’s manual.
Cut is not square	Blade not perpendicular to table	Adjust blade tilt mechanism.
Blade binding	Blade not parallel to the fence	Ensure fence is properly aligned with the miter slot.

Table Saw Maintenance: Keeping Your Saw in Top Condition

Regular table saw maintenance is essential for safety and performance. Here are some tips:

• Clean the Saw Regularly: Remove sawdust and debris after each use.
• Lubricate Moving Parts: Apply lubricant to the trunnion gears, height adjustment mechanism, and tilt mechanism. Use a dry lubricant to avoid attracting sawdust.
• Check Belts and Pulleys: Inspect the belts for wear and tear and replace them if necessary. Ensure the pulleys are aligned.
• Keep Blades Sharp: Sharpen dull blades or replace them.
• Inspect Cords and Plugs: Check the power cord and plug for damage and replace them if necessary.
• Calibrate Regularly: Check and calibrate the fence, miter gauge, and blade alignment periodically.
• Store Blades Properly: Store blades in a dry place to prevent rust.

Fathoming Blade Types for Your Ridgid Table Saw

Choosing the right blade is important for achieving the best results. Here’s a brief overview of common table saw blade types:

• General Purpose Blades: These blades are designed for cutting a variety of materials, including hardwoods, softwoods, and plywood. They typically have 40-50 teeth.
• Rip Blades: Rip blades are designed for cutting wood along the grain. They have fewer teeth (24-30) and a steeper hook angle, which allows for faster cutting.
• Crosscut Blades: Crosscut blades are designed for cutting wood across the grain. They have more teeth (60-80) and a shallower hook angle, which produces smoother cuts with less splintering.
• Plywood Blades: Plywood blades have a high tooth count (80+) and a special grind that minimizes splintering when cutting plywood and other veneered materials.
• Dado Blades: Dado blades are used to cut wide grooves or dadoes in wood. They consist of multiple blades and chippers that can be adjusted to create different widths.
• Metal Cutting Blades: These blades are designed for cutting non-ferrous metals like aluminum and brass. They typically have carbide teeth and a negative hook angle.

Common Mistakes to Avoid

• Forgetting to Disconnect Power: This is the most dangerous mistake.
• Using the Wrong Tools: Always use the correct size wrenches and tools.
• Overtightening the Arbor Nut: This can damage the arbor or blade.
• Installing the Blade Backwards: Ensure the blade is rotating in the correct direction.
• Neglecting Safety Guards: Always use the blade guard and riving knife.
• Skipping the Test Cut: Always make a test cut to ensure the blade is cutting properly.
• Ignoring the Owner’s Manual: Read and follow the manufacturer’s instructions.
