How To Change Dewalt Mitre Saw Blade

A Dewalt mitre saw is a powerful tool that can make precise cuts with ease. However, over time, the blade will become dull and need to be replaced. In this article, we will show you how to change Dewalt mitre saw blade.

Step 1: Safety First

Before we begin, it’s important to remember that safety should always come first. Make sure the saw is unplugged and the blade is completely stopped before attempting to change it. Wear protective gloves to prevent any injury from the sharp blade.

Step 2: Remove the Blade Guard

The blade guard is the plastic cover that protects the blade. To remove it, locate the lever or button on the saw that releases it. Push or pull the lever to release the blade guard and then lift it off of the saw.

Step 3: Loosen the Blade Bolt

Using the wrench that came with your saw, loosen the blade bolt by turning it counterclockwise. Be sure to hold the blade in place with your other hand to prevent it from turning as you loosen the bolt.

Step 4: Remove the Blade

Once the bolt is loose, you can remove the blade. Carefully lift it up and off of the saw. Be sure to take note of the direction of the teeth on the blade, so you can install the new blade correctly.

Step 5: Install the New Blade

To install the new blade, simply reverse the steps you took to remove the old blade. Place the new blade onto the saw, making sure the teeth are facing in the correct direction. Tighten the blade bolt by turning it clockwise with the wrench.

Step 6: Reattach the Blade Guard

Once the new blade is securely in place, you can reattach the blade guard. Simply slide it back into place and secure it with the lever or button you used to release it.
