What is Kick Back?
Kickback is a violent motion in which you rapidly move your hands and arms back.
This is used to describe the action of an individual who has suddenly become scared during work in power saw.
What Causes Kickback on Table Saw?
Kickback is a common occurrence when using a table saw and can be caused by several factors.
In general, kickback happens when the workpiece being cut is suddenly propelled backward towards the operator, often with great force.
This can be extremely dangerous and can result in serious injury or even death.
Understanding the causes of kickback on a table saw can help you avoid it and stay safe while using the saw.
Improperly Aligned Blade
One of the primary causes of kickback on a table saw is an improperly aligned blade.
If the blade is not parallel to the miter slot, it can cause the wood to bind and twist, resulting in kickback.
It’s important to check the alignment of the blade regularly and adjust it as necessary to prevent kickback.
Dull blade
A dull blade can also cause kickback on a table saw. A dull blade will have a harder time cutting through the wood, and as a result, it may cause the wood to bind or twist.
This can lead to kickback. It’s important to keep the blade sharp and in good condition to prevent kickback.
Incorrect blade height
Another factor that can cause kickback on a table saw is an incorrect blade height.
If the blade is too high, it can cause the wood to lift up off the table and bind, resulting in kickback.
It’s important to adjust the blade height correctly for the thickness of the wood being cut.
Pushing the wood too fast
Pushing the wood through the blade too quickly can also cause kickback on a table saw.
When you push the wood too fast, it can cause the blade to bind and twist the wood, leading to kickback.
It’s important to feed the wood through the blade at a steady pace and avoid rushing the cut.
Incorrect fence positioning
The fence on a table saw is used to guide the wood through the blade.
If the fence is not positioned correctly, it can cause the wood to bind and twist, resulting in kickback.
It’s important to ensure that the fence is parallel to the blade and properly positioned for the cut being made.
Knots or defects in the wood
Finally, knots or defects in the wood can also cause kickback on a table saw.
These imperfections can cause the wood to bind and twist, leading to kickback.
It’s important to inspect the wood for knots or defects before making the cut and avoid using wood with significant imperfections.
By properly aligning the blade, keeping it sharp, adjusting the blade height, feeding the wood through at a steady pace, positioning the fence correctly, and inspecting the wood for defects, you can minimize the risk of kickback and work with confidence on your table saw.
What Are Anti Kickback Pawls?
Anti-kickback pawls are small metal teeth or hooks that protrude from the top of a saw’s guide bar.
They’re designed to grip the wood being cut and prevent the saw from being pushed back towards the user in the event of kickback.
Anti-kickback pawls are typically found on chainsaws, circular saws, and table saws.
A kickback pawl is a part of the clutch mechanism of a power tool. It locks the drive shaft and prevents it from moving when you release your grip on the handle.
The anti-kickback pawls of a saw are like minuscule, tiny versions of the teeth on your mouth.
They hang behind in order to prevent large chunks from coming back at you when feeding wood through it.
Why Anti-Kickback Pawl is Important
Anti-kickback pawls are an essential safety feature in power saws, designed to protect the user from injury.
Kickback is a common hazard that can occur when the saw blade binds in the wood or encounters a knot, causing the saw to jump back towards the user.
This can cause serious injury or even death. Anti-kickback pawls help prevent kickback by gripping the wood and stopping the saw from moving backward.
This makes power saws safer and easier to use, especially for beginners or those working with large or difficult-to-cut materials.
People who don’t wear seatbelts are putting themselves in harm’s way. Similarly, people who use table saws without anti-kickback pawls risk being harmed by the blade coming back to them if it kicks out of its cut.
Use and Working Mechanism of Anti Kickback Pawl
Anti-kickback pawls are an important safety feature found on many table saws.
They work by preventing the workpiece from being thrown back towards the operator in the event of a kickback.
The anti-kickback pawls are two small arms located on either side of the blade, near the top of the blade guard.
They are attached to a spring-loaded bracket that allows them to move up and down as the workpiece is fed through the blade.
When the blade rotates in a forward motion, the pawls move freely across the surface of the wood.
However, if the wood tries to move backwards, the pawls dig into the surface of the wood, preventing it from being kicked back.
The mechanism that enables the pawls to move up and down is called the riving knife. The riving knife is a small, vertical projection located behind the blade.
It is mounted on a bracket that allows it to move up and down with the blade.
As the blade cuts through the wood, the riving knife holds the wood open, preventing it from binding against the back of the blade.
This helps to prevent kickback by keeping the wood moving forward smoothly and without any sudden stops.
When kickback occurs, the anti-kickback pawls engage with the surface of the wood and prevent it from being thrown back towards the operator.
The pawls dig into the wood and grip it tightly, stopping it from moving backwards.
This helps to keep the operator safe by preventing them from being struck by the workpiece or the blade.
It’s important to note that while anti-kickback pawls are effective at preventing kickback, they are not foolproof.
It’s still important to follow proper safety procedures when operating a table saw, such as using a splitter, featherboard, and push stick, and maintaining a clean work area.
By using these safety features in conjunction with the anti-kickback pawls, you can significantly reduce the risk of kickback and operate your table saw safely and effectively.
How to Prevent from Table Saw Kickback Happening?
Preventing kickback on a table saw is essential for maintaining safety in the workshop.
Here are some steps you can take to prevent kickback from happening:
Use a splitter
A splitter is a small vertical projection located behind the blade that helps to prevent the wood from pinching the blade and causing kickback.
Many table saws come with a splitter, but if yours does not, it’s worth investing in one. You can also purchase a riving knife, which is a type of splitter that moves up and down with the blade.
Use a featherboard
A featherboard is a device that attaches to the fence and applies pressure to the wood to keep it from moving during the cut.
It helps to prevent kickback by keeping the wood in contact with the table and fence.
Use a push stick
A push stick is a tool that is used to push the wood through the blade. It keeps your hands away from the blade and allows you to apply pressure to the wood without risking injury.
Using a push stick helps to prevent kickback by allowing you to guide the wood through the blade safely and effectively.
Keep the blade sharp
A dull blade is more likely to cause kickback because it has a harder time cutting through the wood. It’s important to keep the blade sharp so that it can make clean cuts without binding or twisting the wood.
Use proper technique – Proper technique is crucial for preventing kickback.
Make sure you’re feeding the wood through the blade at a steady pace, using the right blade height for the thickness of the wood, and positioning the fence correctly.
You should also avoid pushing the wood through the blade too quickly or applying too much pressure.
Use high-quality wood
Knots, warps, and other defects in the wood can cause kickback. To minimize the risk, use high-quality wood that is straight and free of defects.
Maintain a clean work area
Sawdust and debris can cause the wood to bind and twist, leading to kickback.
Keep your work area clean and free of sawdust, and regularly clean the table saw and its components to prevent debris from interfering with your cuts.
By following these steps and taking proper safety precautions, you can significantly reduce the risk of kickback on your table saw.
Remember to always prioritize safety when working with power tools and seek professional help or instruction if needed.
