Kickback is one of the most dangerous situations that can occur when using a table saw. It happens when a piece of wood gets caught in the blade and is forcefully thrown back towards the operator. This can result in severe injury or even death. Therefore, it is crucial to take necessary precautions and follow safety guidelines to avoid kickback.
Here are some important tips to help you avoid kickback on a table saw:
1. Use a riving knife or splitter: A riving knife or splitter is a safety device that helps prevent kickback. It is installed behind the blade and helps to keep the wood from pinching the blade, reducing the risk of kickback. Make sure it is properly aligned and adjusted.
2. Maintain proper blade height and alignment: The blade should be set at the correct height, just above the wood being cut. If the blade is too high, it increases the chances of kickback. Additionally, ensure that the blade is properly aligned so that it cuts straight and doesn’t bind, which can also lead to kickback.
3. Use anti-kickback pawls: Anti-kickback pawls are another safety feature that can help prevent kickback. These small devices attach to the riving knife or splitter and grab the wood if it starts to move backward, preventing kickback. Make sure they are properly installed and functioning correctly.
4. Avoid cutting warped or twisted wood: Warped or twisted wood is more likely to bind or pinch the blade, increasing the chances of kickback. If possible, avoid using such wood on a table saw. Instead, use a different tool or technique to straighten or prepare the wood before cutting.
5. Use a push stick or push block: When cutting smaller pieces of wood, always use a push stick or push block to keep your hands at a safe distance from the blade. This not only helps to prevent kickback but also protects your fingers from any accidental contact with the blade.
6. Maintain a steady feed rate: A steady and controlled feed rate helps to prevent kickback. Avoid pushing the wood too quickly or forcefully through the blade, as this can cause the wood to bind or kickback. Keep a firm grip on the wood and maintain a consistent feed rate throughout the cut.
Remember, safety should always be the top priority when using a table saw. By following these tips and practicing good safety habits, you can greatly reduce the risk of kickback and ensure a safe woodworking experience.

1. Use a Riving Knife
Always make sure to install and properly adjust a riving knife on your table saw. A riving knife helps to prevent kickback by keeping the wood from pinching onto the back of the blade, reducing the risk of it being propelled back towards the operator.
2. Maintain Proper Blade Height
Keep the blade height properly adjusted to the thickness of the material being cut. When the blade height is too high, there is a greater chance of kickback occurring. Adjust the blade height so that it barely clears the top of the material being cut.
3. Use a Splitter
In addition to a riving knife, using a splitter can further help prevent kickback. A splitter is a vertical projection located behind the blade, and it helps to prevent the wood from closing in on the back of the blade, reducing the risk of kickback.
4. Use an Outfeed Support
When cutting longer or heavier materials, it’s important to have an outfeed support to help properly support the material as it exits the saw. This prevents the wood from sagging or binding, which can lead to kickback.
5. Avoid Forceful Feeding
Never force the material through the blade at an excessive speed. Instead, let the saw’s cutting speed and the sharpness of the blade do the work. Applying excessive force can cause the wood to bind and kickback.
6. Use Push Sticks and Featherboards
Utilize push sticks and featherboards to maintain control over the material being cut. Push sticks can keep your hands at a safe distance from the blade, while featherboards help to hold the material against the fence and table, reducing the risk of kickback.
7. Keep the Work Area Clean
Ensure the work area is clear of any debris, especially loose scraps of wood. These can interfere with the smooth movement of the material, increasing the chances of kickback occurring.
Conclusion
By following these tips, you can greatly reduce the risk of kickback on a table saw. Always prioritize safety and exercise caution while operating a table saw to ensure a safe and productive woodworking experience.
Proper Blade and Fence Alignment
One of the most important ways to prevent kickback on a table saw is to ensure proper blade and fence alignment. When the blade and fence are not aligned correctly, it can cause binding, binding, and ultimately kickback. Here are some steps to ensure proper alignment:
- Start by unplugging the table saw and removing the blade guard and splitter.
- Next, use a combination square to check the alignment of the blade. Place the square against the blade and adjust the tilt and height until it is perfectly square.
- Then, measure the distance between the fence and the blade at the front and back of the table. They should be parallel. If not, adjust the fence accordingly.
- Use a straight edge or a long level to check the alignment of the fence itself. It should be perfectly straight and not bowed or twisted.
- After making any adjustments, recheck the alignment to ensure everything is square and parallel.
Proper blade and fence alignment is crucial for preventing kickback and achieving accurate cuts. Take the time to regularly check and adjust the alignment of your table saw, and always follow the manufacturer’s instructions for your specific model.
