Steps To Change The Blade

Changing the blade on your Dewalt circular saw is a simple process that can be completed in just a few easy steps.

Whether you need to replace a dull blade or switch to a different type for a specific project, following these steps will ensure a smooth and safe blade change. Take a look at each step below:

Locating The Blade Release

The first step is to locate the blade release on your Dewalt circular saw. This button or lever is typically found on the side or near the back of the saw.

Carefully inspect your saw to find the exact location of the blade release before proceeding to the next step.

Removing The Old Blade

Once you have located the blade release, press and hold it down firmly. This action will immobilize the blade and prevent it from spinning.

With the blade immobilized, use a wrench to turn the blade nut counterclockwise. Loosen the nut until you can remove it completely.

With the nut removed, carefully lift the old blade off the saw, taking care to avoid any sharp edges. Set it aside in a safe place, making sure it is out of the reach of children or pets.

Installing The New Blade

Before installing the new blade, inspect it for any damages or defects. Ensure that it is the correct size and type for your Dewalt circular saw, as specified in the saw’s manual.

Align the hole in the center of the blade with the arbor on the saw, making sure it is seated securely.

Tightening The Blade Nut

After installing the new blade, it is important to properly tighten the blade nut to ensure the blade is secure. Use the wrench to turn the blade nut clockwise, tightening it as much as possible while still being able to remove it with the wrench.

Inspect the blade to make sure it is centered and aligned correctly. Proper alignment will ensure smooth and efficient cutting. Once you are satisfied with the blade’s position, give the blade nut a final tighten to ensure a secure fit.
