How To Prevent Kickback On Table Saw & Avoid Injury

Kickback on a table saw is a dangerous event where the wood being cut is violently thrown back towards the operator. The most effective ways to prevent kickback include using proper safety devices like the riving knife and anti-kickback pawls, employing correct cutting techniques such as using push sticks and featherboards, and avoiding conditions that make kickback more likely, such as warped wood or incorrect blade height. This article provides a comprehensive guide to preventing kickback and ensuring table saw safety.

The Gravity of Table Saw Safety

Table saws are powerful tools, but they can also be incredibly dangerous if not used correctly. Table saw accident prevention is crucial. Kickback is one of the most common causes of injuries. Understanding how it happens and how to prevent it is essential for every woodworker. Let’s look at table saw safety to keep you safe in your workshop.

Dangers of Kickback: A Hard Lesson

Kickback happens when the blade catches the wood and throws it back at high speed. This can cause severe injuries, including:

• Cuts and lacerations
• Bruises and broken bones
• Eye injuries
• In rare cases, even death

Knowing the risks is the first step in staying safe. Let’s dig into the kickback causes.

Kickback Causes: Decoding the Danger

The first step in table saw accident prevention is to know the potential kickback causes. Several factors can contribute to kickback:

• Pinched Blade: If the wood pinches the blade, it can grab the wood and throw it back.
• Misalignment: If the fence is not parallel to the blade, the wood can bind and kick back.
• Warped Wood: Wood warping effects can cause the wood to bind as it’s cut.
• Freehand Cutting: Cutting without a fence or miter gauge increases the risk.
• Incorrect Blade Height: Using the wrong blade height and kickback relation can cause problems.
• Loss of Control: Hesitation, distraction, or improper technique are huge factors.

Essential Safety Devices: Your First Line of Defense

Your table saw comes with safety devices designed to prevent kickback. Make sure these are properly installed and used every time.

The Riving Knife: A Vital Component

The riving knife is a metal piece behind the blade. It keeps the wood from pinching the blade after it’s cut. Proper riving knife adjustment is key.

• Function: Prevents the wood from closing back on the blade.
• Adjustment: Adjust the riving knife so it’s close to the blade but doesn’t touch it.
• Usage: Always use the riving knife unless you’re making a cut where it must be removed (like a non-through cut).

Anti-Kickback Pawls: Gripping Power

Anti-kickback pawls are toothed devices that grip the wood and stop it from being thrown backward.

• Function: Prevent the wood from moving backward during a kickback.
• Maintenance: Check the pawls regularly to make sure they’re sharp and functioning correctly.
• Limitations: While helpful, they are not a substitute for good technique.

Blade Guard: Not Just for Show

The blade guard covers the blade to prevent accidental contact.

• Function: Protects your hands from the spinning blade.
• Usage: Keep the blade guard in place whenever possible. It can be removed for some cuts, but always replace it when you can.

Table: Safety Device Functionality

Safety Device	Function	Maintenance
Riving Knife	Prevents pinching and kickback	Keep adjusted close to the blade
Anti-Kickback Pawls	Grips wood to prevent backward movement	Check for sharpness and proper function
Blade Guard	Protects hands from the blade	Keep in place whenever possible

Safe Cutting Practices: The Path to Prevention

Using safe cutting practices dramatically reduces the risk of kickback.

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 edge.

• Function: Keeps your hands away from the blade.
• Usage: Use a push stick for any cut where your hands would be close to the blade.
• Types: There are many different push sticks, from simple to more advanced. Find one that works for you.

Featherboard Setup: Controlling the Cut

A featherboard is a device that holds the wood against the fence, ensuring a consistent cut and preventing kickback.

• Function: Applies pressure to the wood, keeping it against the fence.
• Placement: Place featherboards both before and after the blade for maximum control.
• Types: Featherboards can be magnetic, mechanical, or shop-made.

Miter Gauge: Accurate Crosscuts

The miter gauge is used for making accurate crosscuts (cuts across the grain).

• Function: Guides the wood straight across the blade.
• Usage: Use the miter gauge for crosscuts instead of freehand cutting.
• Safety: Make sure the miter gauge fits snugly in the slot and doesn’t wobble.

Managing Wood Warping Effects

Warped wood is a common cause of kickback. Here’s how to deal with it:

• Inspection: Before cutting, inspect the wood for warps, bows, twists, and cups.
• Straightening: If possible, straighten the wood before cutting. A jointer and planer can help.
• Cutting Strategy: Plan your cuts to minimize the risk of binding.
• Waste: Always position the warped area of the wood as the waste side. This means the part being cut off should be warped rather than the straight, keeper piece.

Addressing Blade Height and Kickback

The height of the blade above the wood affects the risk of kickback.

• Optimal Height: The blade should be high enough to cut through the wood, but not excessively high. A good rule of thumb is to have the blade teeth extend about 1/4 inch above the top of the wood.
• Excessive Height: Using an excessively high blade increases the chance of the wood climbing the blade and being thrown back.
• Low Height: Too low a blade can cause you to force the wood, increasing the chance of loss of control and other table saw accident prevention missteps.

Preventing Pinches: A Simple Fix

Preventing the wood from pinching the blade is crucial.

• Riving Knife: As mentioned earlier, make sure the riving knife is properly installed and adjusted.
• Cutting Order: Plan your cuts to avoid creating internal stresses in the wood.
• Relief Cuts: For some complex cuts, you may need to make relief cuts to relieve tension in the wood.

Avoiding Freehand Cutting: A Must-Do

Freehand cutting (cutting without a fence or miter gauge) is extremely dangerous and should always be avoided.

• Risk: Without a guide, it’s easy for the wood to twist or bind, leading to kickback.
• Solution: Always use a fence, miter gauge, or other guide to keep the wood moving straight.

Additional Safety Tips: Going the Extra Mile

Besides the above practices, here are a few more tips to keep you safe:

• Clear Workspace: Keep your workspace clean and free of clutter.
• Proper Lighting: Make sure you have good lighting so you can see clearly.
• Stay Focused: Avoid distractions while operating the saw.
• Avoid Reaching: Don’t reach over the blade to grab something.
• Plan Ahead: Think through each cut before you make it.
• No Gloves: Do not use gloves while using a table saw. They can catch on the blade and pull your hand in.
• Training: Consider taking a woodworking class to learn safe techniques.
• Take Breaks: When you get tired, take a break. Fatigue increases the risk of accidents.
• Know Your Saw: Read and understand your table saw’s manual.
• Inspect your Equipment Regularly: Check your saw’s components often to make sure they’re well-maintained and in good working order.
• Stay Calm: A calm and steady mind helps you stay focused and avoid mistakes.
• Be Aware of Your Body Position: Be aware of where your hands are in relation to the blade and avoid awkward positions.
