Installing a blade on a Craftsman circular saw is a simple task that can be done in a few steps. It is important to keep your saw blades sharp and replace them when they get dull to ensure clean and accurate cuts. Before starting, make sure the saw is unplugged or the battery is removed for safety reasons. You will also need a wrench, which is typically included with the saw and stored in a slot on the saw body. If you don't have the wrench, you can use an open-end or socket wrench, or an adjustable wrench.

What You'll Learn
Ensure the saw is unplugged or the battery is removed
When installing a new blade on your Craftsman circular saw, safety should be your top priority. As such, the first step is to ensure that the saw is unplugged from its power source. If you have a corded model, unplug it from the power outlet. If your saw is cordless, remove the battery. This is a crucial step as you do not want the saw to accidentally start while you are in the process of changing the blade.
It is also important to note that you should not skip this step. Even if you think your saw is unplugged or the battery is removed, double-check to make sure. It is always better to be safe than sorry when working with power tools.
Once you have confirmed that the power source is disconnected, you can proceed to the next step of changing the blade on your Craftsman circular saw. Remember, safety comes first, so take your time and follow the instructions carefully.

Find the correct replacement blade
Finding the correct replacement blade for your Craftsman circular saw is a crucial step in ensuring optimal performance and accurate cuts. Here's a detailed guide to help you through the process:
First, it is important to understand that circular saw blades come in different types and sizes, and choosing the right one is essential. The correct blade will depend on the specific model of your Craftsman circular saw and the material you intend to cut. For example, a blade designed for cutting wood will not be suitable for cutting granite. Therefore, ensure you identify the correct blade type and size for your saw.
Next, you should consult the user manual that came with your Craftsman circular saw. The manual will provide specific information about the saw, including the recommended blade type and size. It will also guide you on any unique aspects of replacing the blade for your particular model. This information will be invaluable in ensuring you select the correct replacement blade.
Additionally, consider the type of cuts you need to make. Different blades are designed for various cut types, such as rough cuts, finish cuts, cross cuts, and rip cuts. Selecting the appropriate blade for the desired cut will ensure better results and prolong the life of your blade.
When purchasing a replacement blade, ensure it matches the size of your circular saw. For instance, a 10-inch blade circular saw requires a 10-inch replacement blade, and a 7-1/4 inch blade unit should have a 7-1/4 inch blade. Using the correct size is essential for the proper functioning and safety of your saw.
Finally, consider the material of the blade. Most circular saw blades are made of carbide-tipped steel or other durable materials. The type of material you plan to cut will influence the choice of blade material. For example, cutting through harder materials like metal or granite may require a blade with a different composition or coating to withstand the increased wear.
By following these guidelines and consulting the user manual, you can confidently select the correct replacement blade for your Craftsman circular saw, ensuring optimal performance, accuracy, and safety.

Secure the blade guard and arbor
To secure the blade guard and arbor of your Craftsman circular saw, follow these steps:
Place the saw on a solid surface and pull back the blade guard to expose the blade. Every circular saw has a blade guard that covers the blade, so you'll need to pull it back to access the blade and arbor.
Engage the arbor lock if your circular saw has one. Some circular saws have an arbor lock, which is a button that locks the blade in place. If your saw has this feature, be sure to engage it to secure the blade.
If your saw doesn't have an arbor lock, press the blade against a wooden surface to secure it. If your saw doesn't have an arbor lock, you can still secure the blade by pressing it against a wooden surface. This will prevent the blade from moving while you work on it.
Loosen the arbor nut using the wrench that came with your saw. The arbor nut holds the blade in place, and you'll need to loosen it to remove the old blade and install the new one. Use the wrench that came with your saw and turn it in the appropriate direction to loosen the nut.
Slide the old blade out and insert the new blade. Once the arbor nut is loosened, you can slide the old blade out and insert the new one. Make sure the new blade is aligned correctly and sits snugly in place.
Tighten the arbor nut to secure the new blade. After inserting the new blade, tighten the arbor nut using the wrench. Be careful not to over-tighten the nut, as this can make it difficult to loosen the next time you need to change the blade.
Reinstall the blade guard. Once the new blade is in place and secured, you can reinstall the blade guard. Align it with the saw's holes and secure it with the provided screws.
By following these steps, you can securely install a new blade on your Craftsman circular saw, ensuring maximum safety and optimal performance.

Loosen the arbor nut with a wrench
To loosen the arbor nut with a wrench, follow these steps:
First, locate the wrench that came with your saw. It is usually stored in a slot on the saw body and can be removed by simply pulling it out. If you've lost the wrench, you can use an open-end or socket wrench, or even an adjustable wrench, although this may be harder to work with in the limited space.
Next, depress the spindle-lock or arbor-lock button to keep the saw blade from spinning. This will lock the blade in place, making it possible to remove the bolt. Continue to hold down the button while using the wrench to loosen the arbor nut.
Turn the wrench in the same direction as the blade cuts to loosen the nut. On a corded right-hand circular saw, this will be counterclockwise, while a left-hand saw will be clockwise. You can also follow the arrow on the upper or lower blade guard for the blade rotation and loosen the bolt in the same direction as the arrow.
If the bolt is stuck, try using lubricating oil, such as WD-40, to help loosen it. Once the arbor nut is loosened, you can slide the blade out and replace it with a new one.

Replace the old blade with the new one
Now that the old blade has been removed, you can replace it with the new one. Take the new blade and slip it onto the saw's arbor, ensuring that the teeth of the saw face the direction of rotation. If you are unsure, refer to the arrow on the saw's blade guard. The arrow on the new saw blade should match the arrow on the guard, indicating the blade is rotating in the correct direction.
Once the new blade is in place, slide the washer onto the shaft. Turn the washer until it drops in place snug against the blade. Then, use the blade wrench to tighten the arbor nut until it is finger-tight. Do not over-tighten the nut, as this will make it difficult to loosen the next time you change the blade.
Next, lock the blade by depressing the blade lock button. Finally, use the wrench to give the bolt a final tighten, turning it about 1/8th of a turn. With the new blade installed, you can now plug in the circular saw or insert the battery to test it out.
