Step 6: Clean the Arbor and Install the New Blade
Before attaching the new blade, take a moment to clean the arbor. Removing sawdust and debris from the area can prolong the life of your new blade.
Now, it’s time to install the new blade:
- Place the new blade onto the arbor with the teeth facing the correct direction. Most blades have an arrow indicating the direction of spin.
- Reattach the washer and arbor nut, tightening it in place (be careful not to overtighten as this may strip the threads).
Step 7: Release the Blade Lock
After the new blade is securely attached, press the blade lock button again to release it. At this point, give the blade a gentle spin to ensure it moves freely without resistance.
Step 8: Reinsert the Battery
With everything in place, you can now reinsert the battery.
Step 9: Test the Saw
Before starting any cutting project, it’s a good practice to run a few tests:
- Turn on the saw and let it run for a few seconds to ensure everything is functioning properly.
- Observe for any unusual sounds or vibrations.
If you notice anything out of the ordinary, double-check that the blade is securely mounted.
Maintaining Your Circular Saw Blade
Changing your blade is only one part of the equation. To maximize the performance of your Dewalt cordless saw, follow these maintenance tips:
Regular Cleaning
After every few uses, take the time to clean your blade. Remove any resin buildup or debris, which can cause overheating and dull the blade.
Proper Storage
When not in use, store your saw in a dry place. Consider using a blade guard to protect edges and keep them sharp.
Use the Right Blade for the Job
Different materials require different blades. Make sure to choose a blade specifically designed for the material you plan to cut (wood, metal, plastic, etc.).

What tools do I need to change the blade on my Dewalt cordless circular saw?
To change the blade on your Dewalt cordless circular saw, you will primarily need a replacement blade that fits your specific model. Additionally, it’s advisable to have a wrench, typically included with the saw, which allows you to loosen the blade’s arbor nut easily. A pair of safety gloves can also enhance your protection during the process, ensuring you prevent any accidental cuts.
Having a work surface or a clamp where you can secure the saw while changing the blade can also be beneficial.

Before beginning, make sure your workspace is well-lit, and consider wearing safety goggles to protect your eyes from any debris.
How do I know which replacement blade to purchase?
Selecting the right replacement blade for your Dewalt cordless circular saw is crucial for optimal performance and safety. You can typically find the compatible blade size in the user manual of your saw. Most Dewalt circular saws use either a 6.5-inch or 7.25-inch blade, but it’s always wise to double-check your specific model’s requirements.
Another consideration is the type of material you’ll be cutting. Different blades are designed for different purposes, such as cross-cutting, ripping, or cutting specific materials like plywood or metal. Make sure to choose a blade marked for the intended application to ensure a clean cut and to increase the blade’s lifespan.
Do I need to unplug my saw before changing the blade?
Yes, it is crucial to unplug your Dewalt cordless circular saw before attempting to change the blade. Although cordless saws do not have a power cord, you should remove the battery pack to ensure that the saw cannot accidentally turn on during the blade replacement process. This precaution significantly reduces the risk of injury and enhances your safety.
Additionally, it’s a good practice to always work under the assumption that a power tool can suddenly start, even if you’ve taken precautions. By fully disarming the saw, you can focus entirely on the task at hand without being distracted by thoughts of safety or potential accidents.
How do I remove the old saw blade?
To remove the old blade from your Dewalt cordless saw, begin by pressing the blade lock button, which will allow you to stabilize the blade while you loosen the arbor nut with your wrench. Turn the wrench counterclockwise to loosen the nut; depending on your model, the nut may have a standard right-hand thread. Once it’s loose, you can completely remove the nut and the outer washer.
After removing these components, carefully lift the old blade off the saw’s arbor. Be sure to handle it with caution, as the blade’s teeth can be sharp. Take a moment to inspect the arbor for any debris or damage before proceeding to install the new blade.
What safety precautions should I take while changing the blade?
When changing the blade on your Dewalt cordless circular saw, it’s essential to follow a few safety precautions to prevent accidents. First, ensure you’re wearing personal protective equipment, such as safety goggles and gloves. This will help protect your eyes from flying debris and your hands from accidental cuts while handling the blade.
Furthermore, ensure that your workspace is clutter-free and well-lit to prevent mishaps. Having your tools within easy reach can also minimize the need for unnecessary movements while changing the blade. Lastly, keep any bystanders or pets at a safe distance from your workspace to reduce the risk of distractions or accidents during the process.
How do I properly install the new blade?
To install the new blade, start by placing the inner washer onto the saw’s arbor, followed by the new blade. Make sure to orient the blade correctly—look for directional arrows on the blade and align them with the saw’s rotation. After positioning the blade, place the outer washer and then hand tighten the arbor nut to hold everything in place.
Once the components are properly aligned, use your wrench to tighten the arbor nut securely, turning it clockwise. Be cautious not to over-tighten, as this can damage the components. After completing the installation, rotate the blade by hand briefly to ensure it spins freely without any obstruction before using the saw.
Why does my saw blade wobble after replacement?
A wobbling saw blade after replacement can indicate a few potential issues. One common reason is an improperly seated blade; if the blade is not aligned correctly on the arbor or if the washers are installed improperly, this may cause an imbalance. Always ensure that both the inner and outer washers are correctly placed and that the blade is secured firmly.
Another possible reason for a wobbling blade could be a damaged blade or arbor. Check the blade for any visible signs of warping and the arbor for damage or debris that could prevent a snug fit. If you notice any issues, it may be necessary to replace the blade or repair any damaged components to restore proper function.
