A good table saw is practically a necessity for lots jobs like installing hardwood floors. There’s been a lot of talk lately about table saw safety and whether or not the Consumer Product Safety Commission (CPSC) will mandate the use of a new technology called the SawStop. No matter what you think about the SawStop, the onus is still on the user to be safe. This post includes some of the safety guidelines suggested by the The California Polytechnic State University and other best practices.
If you’ve never heard about the SawStop technology, it’s designed to immediately stop the blade when it comes in contact with skin. The saw blade will be shot but it’s a very effective safety mechanism. You can find lots of SawStop demonstrations on YouTube if you look around.
Table Saw Safety Procedures
Whether you’re using a table saw, miter saw or any other power tool, it’s important for the operator to wear safety glasses and, at times, a face shield. Skip the work-gloves as any good table saw will cut right through them and you’ll lose your sense of touch. You should also consider hearing protection, not just for a table saw but all power tools.
You want to run through a short list of checks before using a table saw. It’s not a bad idea to print out this list and tape it down to the surface of your saw as a constant reminder. This can also be useful when teaching teenagers to work with the tool.
- Verify location of off switch and/or emergency power disconnect and ensure that the table saw is off before proceeding.
- Check blade for tightness and sharpness.
- Check the hood guard and anti-kickback devices for proper operation
- If used, check to ensure the fence is set properly and tight
- Ensure that the table is clear of materials, tools, and debris
Position yourself comfortably and well balanced but not directly in-line with the blade. Standing to the side of the wood minimizes the danger from kickback. Kickback occurs when, rather than cutting a board, the spinning saw blade grabs the board and throws it back at you.
If your stomach is in the way of the oncoming board when this happens, you could very well end up with a serious abdominal injury. The risk of this happening is increased when using a dull blade on the table saw, or when cutting hard lumber, such as jatoba, cumaru, or purple heart. Extra precaution is critical in this situation. We have found that this mistake is extremely common with new table saw users who may be careless in their standing position.
Set the blade height so that the top of the teeth are no more than a 1/4″ above the wood. Check the blade guards, splitters and anti-kickback device before starting. Always use the fence or miter gauge, and never try to cut freehand. Use feather boards to hold the stock securely against the fence and push sticks to move stock through the saw. Always keep your hand 6″ or more away from the blade.
Try to keep the boards moving through the saw at a slow and steady pace. If you try to overcut the board (moving it too fast), the risk of kickback is greatly increased.
Disconnect the power before changing the blade or servicing the saw (and double check).
The Right Saw Blade
Choosing the right saw blade can go a long way in keeping an operator safe, and it can be a huge difference in how well your saw performs.
