7 Lifesaving Tips for How to Use a Table Saw Safely:
- Always Use the Blade Guard and Splitter Leaving the blade guard off exposes you to the spinning blade and increases kickback risk. The splitter helps prevent woodworking pieces from pinching the blade.
- Get a Riving Knife A riving knife is a curved guard that moves with the blade, preventing kickback better than a splitter alone.
- Invest in Push Sticks/Push Blocks Never let your hands get closer than 6 inches to the blade. Use push sticks/blocks to safely push your workpiece through.
- Stand to the Side, Never Inline Position yourself slightly off to the left or right side of the blade’s path to avoid direct exposure if kickback occurs.
- Use Featherboards Featherboards help keep the workpiece tight against the fence and table, preventing binding and kickback.
- Check for Defects Carefully inspect every board before cutting for knots, nails, or cracks that could cause kickback.
- Disconnect Power Before Adjustments
Make it a habit to unplug the saw before adjusting the blade height/tilt or changing the blade entirely.

Frequently Asked Questions
What is the most common cause of table saw injuries?
The most common cause of table saw injuries is kickback, which occurs when the workpiece binds against the blade or is caught and violently thrown back towards the operator. Proper workpiece inspection, blade guard use, and cutting techniques can help prevent kickback.
Is it safe to use a table saw without a blade guard?
No, it is never safe to operate a table saw without a blade guard. The blade guard is a critical safety feature that helps prevent accidental contact with the spinning blade and reduces the risk of kickback. Always keep the blade guard in place and functioning properly.
How often should I replace the table saw blade?
The frequency of blade replacement depends on several factors, including the type of materials you’re cutting, the blade’s quality, and how often you use the table saw. As a general rule, it’s recommended to replace the blade when it shows signs of excessive wear, chipping, or dullness, or when it starts to produce rough or inaccurate cuts.
Conclusion
Operating a table saw safely requires a combination of knowledge, preparation, and vigilance. By understanding the table saw’s components, setting up your workspace properly, wearing appropriate PPE, mastering cutting techniques, and maintaining the tool in good condition, you can greatly reduce the risk of accidents and injuries. Remember, safety should always be the top priority when working with a table saw. Stay focused, follow best practices, and never take shortcuts that could compromise your well-being. With the right approach, you can confidently tackle your woodworking projects while ensuring a safe and productive experience.
