How To Adjust Riving Knife On Dewalt Table Saw
The riving knife is an important safety feature on a table saw that helps prevent kickback and keeps the workpiece from binding. It is a thin, metal blade that sits behind the saw blade and is positioned just slightly higher than the teeth of the blade. If you own a Dewalt table saw and need to adjust the riving knife, this guide will walk you through the process step-by-step.
Step 1: Start by unplugging the table saw and ensuring that the blade is completely stopped. Safety should always be the top priority when working with power tools.
Step 2: Locate the riving knife adjustment screws. These are usually located near the throat plate of the saw or on the back of the saw blade guard. Depending on the model of your Dewalt table saw, there may be one or two screws.
Step 3: Use a screwdriver or wrench to loosen the adjustment screws. This will allow you to adjust the height and position of the riving knife. It is important to only loosen the screws enough to make the necessary adjustments. Be careful not to remove the screws completely, as this could cause the riving knife to become loose.
Step 4: Adjust the height of the riving knife by raising or lowering it to match the height of the saw blade. The riving knife should be set just slightly higher than the teeth of the blade, typically around 1/8 to 1/4 of an inch.
Step 5: Once the height is adjusted, check the alignment of the riving knife with the blade. It should be centered behind the blade and parallel to the teeth. Use a straightedge or a combination square to ensure that the riving knife is aligned correctly.
Step 6: Tighten the adjustment screws once the riving knife is properly aligned. Be sure to tighten them securely, but do not over-tighten as this could damage the threads or cause the screws to strip.
Step 7: Test the adjustment by making a few cuts on a scrap piece of wood. The riving knife should help prevent kickback and keep the workpiece from binding. If you notice any issues, double-check the height and alignment of the riving knife and make any necessary adjustments.
By following these steps, you can easily adjust the riving knife on your Dewalt table saw to ensure safe and accurate cutting. Always remember to wear appropriate safety gear and consult your table saw’s manual for specific instructions for your model.
Why You Need to Adjust the Riving Knife on Your Dewalt Table Saw
The riving knife on your Dewalt table saw is a crucial safety feature that helps prevent kickback and keeps the wood from pinching the blade. However, it may require adjustment from time to time to ensure optimal performance. Here are a few reasons why you need to adjust the riving knife on your Dewalt table saw:
1. Ensuring Proper Blade Clearance
One of the main reasons to adjust the riving knife is to ensure proper blade clearance. The riving knife should be aligned with the blade, but not touching it. If it is too close to the blade, it can cause friction and potentially damage the blade or the riving knife itself.
On the other hand, if the riving knife is too far from the blade, it may not effectively prevent kickback. Kickback occurs when the wood gets caught on the back of the blade and is thrown back towards the operator. Adjusting the riving knife ensures that it is positioned at the correct distance to prevent kickback.
