Turn off your table saw’s motor. Next, adjust your riving knife’s height. When the blade is fully retractable, ensure that the riving knives is at the same height as the blade.
Next, make sure the riving knives are properly set. Make sure the riving knives does not move with the blade moving. Also, check that the riving knife doesnt interfere with the movement of the blade.
The next step is to put the workpiece on the saw table. Hold the workpiece firmly against the fence. Now lower the blade towards the workpiece. Lift the riving blade until the knife touches the blade’s bottom. Lower the blade again until the riving knife touches the bottom of the saw blade.
Press the workpiece carefully against the fence. Slowly retract your blade. As soon as the blade has reached its full extension, stop retracting the blade. Keep the blade stationary for about 10 seconds.
Repeat steps 4-6 until the blade stops vibrating.
Now, slowly lift the riving knife away from the blade. Continue to lift the riving knives until the blade vibrates again. When the blade vibrates again, stop lifting the riving knives.
Keep going until the vibration stops. Once the blade is stable, slowly lower the riving knife back onto the blade. Continue this process until your blade stops vibrating. After each cut, take the riving knives off. When making multiple cuts, do not leave the riving knives on the blade.

How Thin Should The Riving Knife Be
The type of project you are working with will determine the thickness of your riving knife. For example, if you are going to use the riving knife to rip a piece of plywood or hardboard, then a thicker riving knife is needed. If you are using the riving knife to make decorative cuts in softwoods such as mahogany, then a thinner riving knife is required.
Ripping Plywood With A Riving Knife
A good rule of thumb is to always use a riving knife with a minimum thickness of 1/10 cm (0.64 cm). Thicker riving knives are too heavy to handle properly.
To rip plywood, place the plywood face down on a flat surface. Place the riving knife on top of the plywood. Make sure the blade of the riving knife is facing down. Position the riving knife at the center of the plywood. Press firmly down on the riving knife. Slowly move the riving knife along the length of the plywood.
You can rip hardboard by following the same steps, except that instead of placing your riving knife on a flat surface, you place it on a scrap piece of plywood.
