The Danger of Kickback

Kickback is a sudden, violent event. The wood you are cutting can be thrown back towards you at high speed. This can cause serious injury. Preventing kickback injuries is vital for anyone using a table saw. Knowing how kickback happens and how to avoid it is essential for table saw safety.

Why is Kickback So Dangerous?

• High-Speed Projectiles: The wood becomes a dangerous projectile.
• Unexpectedness: Kickback happens suddenly, giving you little time to react.
• Blade Contact: Your hands can be pulled into the blade.
• Loss of Control: You lose control of the wood and the saw.

Fathoming Kickback Causes

Grasping the reasons why kickback occurs is the first step in preventing it. Several factors can lead to this dangerous situation.

Common Kickback Causes

• Pinching: The wood pinches the blade, usually when ripping wood safely. This can happen if the wood is warped or if the fence is not parallel to the blade.
• Binding: The wood binds between the blade and the fence. This can happen if the wood is not fed straight.
• Lifting: Lifting the wood as you feed it. This makes the back of the blade grab the wood.
• Warped Wood: Using wood that is not flat. Warped wood can pinch the blade.
• Dull Blade: A dull blade requires more force, increasing the chance of kickback.
• Incorrect Blade Height: Having the blade too high can increase the risk.

Illustrative Table of Kickback Causes

Cause	Description	Prevention
Pinching	Wood squeezed against the blade	Use straight wood, adjust the fence, use a splitter
Binding	Wood trapped between the blade and fence	Feed wood straight, use featherboards to control workpiece movement
Lifting	Raising the wood during the cut	Keep the wood flat on the table, use a push stick technique
Warped Wood	Wood that is not flat	Select straight wood, flatten the wood before cutting
Dull Blade	Blade requires excessive force	Use a sharp blade, replace or sharpen dull blades
Incorrect Height	Blade is too high above the wood	Adjust blade height correctly

Anti-Kickback Devices: Your First Line of Defense

Anti-kickback devices are essential tools for table saw safety. These devices help prevent the wood from being thrown back at you.

Splitters: Preventing Pinching

A splitter is a metal piece that sits behind the blade. Its main job is to keep the wood from pinching the blade after it has been cut.

• How it Works: The splitter keeps the two sides of the wood separate.
• Benefits: Prevents the wood from squeezing the blade and causing kickback.
• Installation: Most new saws come with a splitter. Make sure it is correctly installed and aligned.
• Maintenance: Check the splitter regularly for damage and proper alignment.

Pawls: Stopping Rearward Movement

Pawls are small, toothed devices that prevent the wood from moving backward. They are usually located just behind the blade.

• How they Work: The teeth dig into the wood if it starts to move back.
• Benefits: Provide an immediate stop to backward movement.
• Usage: Ensure the pawls are sharp and properly adjusted.
• Limitations: Pawls may not work well with very thin or soft wood.

Blade Guards: Protection from Contact

While not strictly anti-kickback devices, blade guards offer critical protection. They shield your hands from accidental contact with the blade.

• How they Work: A clear plastic cover sits over the blade.
• Benefits: Prevents your hands from touching the blade.
• Importance: Always use the blade guard unless a specific cut requires it to be removed (and even then, exercise extreme caution).
• Maintenance: Keep the guard clean and in good working condition.

Mastering Safe Table Saw Techniques

Knowing the right techniques is key to table saw safety. These methods help you maintain control of the wood and prevent kickback.

Controlling Workpiece Movement

Keeping the wood moving smoothly and straight is crucial. Any sudden movements can lead to kickback.

• Steady Feed Rate: Feed the wood at a consistent speed.
• Straight Line: Keep the wood aligned with the fence.
• Avoid Pauses: Do not stop or hesitate mid-cut.
• Firm Grip: Maintain a firm grip on the wood, but don’t force it.

Featherboard Use: Adding Stability

Featherboards are devices that hold the wood firmly against the fence or table. This helps prevent the wood from wandering or lifting.

• How they Work: Angled “feathers” apply pressure to the wood.
• Benefits: Keep the wood tight against the fence. Helps ensure a straight cut.
• Placement: Place featherboards before and after the blade.
• Types: Available in magnetic, clamp-on, and shop-made versions.

Push Stick Technique: Keeping Hands Safe

A push stick is a tool used to push the wood through the blade, keeping your hands away from the cutting area.

• How it Works: Provides a safe way to apply pressure to the wood.
• Benefits: Keeps your hands away from the blade. Maintains control over the wood.
• When to Use: Always use a push stick when cutting narrow pieces.
• Types: Available in various designs, including push blocks and push shoes.

Ripping Wood Safely: A Step-by-Step Guide

Ripping is cutting wood along the grain. Here’s how to do it safely:

1. Select Straight Wood: Choose wood that is flat and straight.
2. Adjust the Fence: Set the fence to the desired width. Make sure it’s parallel to the blade.
3. Adjust Blade Height: Set the blade height so the teeth are just above the wood.
4. Use Anti-Kickback Devices: Install the splitter and pawls.
5. Position Featherboards: Place featherboards before and after the blade.
6. Use a Push Stick: Use a push stick to guide the wood through the blade.
7. Maintain a Steady Feed: Feed the wood at a consistent speed.
8. Keep Hands Clear: Keep your hands away from the blade’s path.

Crosscutting Safely: Using a Miter Gauge

Crosscutting is cutting wood across the grain. A miter gauge helps keep the wood straight and prevents binding.

1. Use a Miter Gauge: Place the wood against the miter gauge.
2. Adjust the Angle: Set the miter gauge to the desired angle.
3. Keep Wood Flat: Keep the wood flat against the table.
4. Push the Gauge: Push the miter gauge and wood through the blade.
5. Keep Hands Clear: Keep your hands away from the blade’s path.
6. Avoid Freehand Cuts: Never crosscut without a miter gauge.

Other Important Safety Measures

Besides anti-kickback devices and techniques, other safety measures are essential.

Personal Protective Equipment (PPE)

• Safety Glasses: Protect your eyes from flying debris.
• Hearing Protection: Table saws are loud. Use earplugs or earmuffs.
• Dust Mask: Protect your lungs from sawdust.
• Close-Fitting Clothing: Avoid loose clothing that can get caught in the blade.

Saw Maintenance

• Sharp Blades: Use a sharp blade. Replace or sharpen dull blades regularly.
• Clean Saw: Keep the saw clean and free of debris.
• Check Alignment: Make sure the blade, fence, and miter gauge are properly aligned.
• Inspect Regularly: Check the saw for any signs of damage or wear.

Work Environment

• Adequate Lighting: Ensure you have enough light to see clearly.
• Clear Workspace: Keep the area around the saw clear of clutter.
• Stable Footing: Make sure you have stable footing.
• Avoid Distractions: Focus on the task at hand.
