Hello. My name is Mark Block and in this segment we're going to cover how to adjust a table saw. Okay, there's a couple basic adjustments for the operator of a table saw, one of which is the height of the blade, which is done by cranking the handle up or down. And the other is the angle of the blade which is done by releasing the locking mechanism and cranking the handle around to change the angle. But before you can use these, you need to ensure that the blade is properly calibrated to the saw. First thing you need to know, you need to make sure this blade is exactly 90 degrees to the edge of the table saw. Because that's what the devices are calibrated off of. If this is not straight with the table itself, you'll end up with crooked cuts and a malfunctioning saw. The way to do this is to use a square, place against one edge of the saw and you want to hold it up, make sure you're tight against the base of the saw and tight against the blade. And you want to check for variances between the front of the blade and the back of the blade. If you have a carbide tooth blade, you want to make sure that you're in between the carbide teeth with your square. So the square itself isn't riding on one of the carbide teeth. And just checking that, you want to make sure that you have the same clearance, actually no clearance, at both the front of th blade and the back of the blade. If this is square, you know your blade is calibrated to the rest of the saw. And using the other adjustments is easy. If its not, you will have to flip the saw over and the specific adjustments for each saw are specific to the saw itself. You'll need to check your owner's manual to get those adjustments to make the calibration in the blade. Another thing you can do, most the pointing devices used for the angle, the actual arrow indicators is calibrateable itself. So you want to check your 90 degrees by using using the corner square, holding it flush on the base, checking it in between the carbide teeth and making sure that's a perfect 90 degree angle. If that's off, adjust the handle until it reaches 90 degrees and then change the calibration on your pointer, which is done by losing the set screw on the bottom and moving it so it reads absolute zero. Then again check the same way doing it at 45. Tilt your blade over to a 45 position. Check it. Make sure that it's accurate and adjust the pointer arrow as indicated. That's how you adjust a table saw.
