This article will walk you through the process of changing the blade on your DWS715, providing you with the knowledge and confidence to tackle this task with ease.
Preparation is Key
Before you begin the process of changing the blade, it’s essential to ensure your safety. Always unplug the saw from the power source to prevent any accidental starts. Safety glasses and a dust mask are also recommended to protect your eyes from debris and your lungs from dust. Familiarize yourself with the tool’s parts and the new blade you’re about to install. It’s crucial to understand the difference between the various types of blades available, as each is designed for specific tasks. For example, a blade designed for cutting wood will not be as effective when cutting metal, and vice versa.
Understanding Blade Types
The market offers a wide range of blades tailored to different materials and cutting techniques. For a DWS715, you’ll commonly use blades designed for crosscuts, rip cuts, or combination blades that can handle both. Crosscut blades are optimized for cutting across the wood grain and typically have more teeth, which result in a smoother finish. Rip cut blades, on the other hand, have fewer teeth and are designed for cutting with the grain, providing faster cuts but with a less smooth finish. Combination blades offer a compromise, carrying out both tasks with decent results, though not as excelling in either as specialized blades.
Choosing the Right Blade
When selecting a replacement blade for your DWS715, consider the types of projects you undertake most often. If you primarily work with wood and need precise crosscuts, a crosscut blade might be your best choice. For those who work with a variety of materials, including metal or plastic, ensure the blade you choose is compatible with these materials. Always refer to the manufacturer’s recommendations for the best performance and longevity of your tool.
Step-by-Step Blade Replacement
Changing the blade on a DWS715 is relatively straightforward but requires attention to detail. The following steps will guide you through the process:
First, locate the blade lock. This mechanism is what holds the blade in place. On the DWS715, you’ll find it near the blade, and it usually involves a lever or a button that needs to be pressed or flipped to release the blade.
Next, remove the blade guard. This may involve screws or clips, depending on your saw’s design. The guard protects you from the spinning blade, so it’s essential to be cautious when handling it.
Then, access the arbor bolt. The arbor bolt is what secures the blade to the saw. You’ll need to use a wrench, typically provided with the saw or a similar one, to loosen this bolt. Remember, the arbor bolt usually loosens counterclockwise.
After loosening the arbor bolt, you should be able to remove the old blade. Be careful, as the blade will be sharp and can cause injury.
Finally, install the new blade, ensuring it’s properly seated and the arbor bolt is tightened in a clockwise direction. Make sure not to overtighten, as this can damage the blade or the saw.
Reassembly and Testing
Once the new blade is installed, reassemble the saw in the reverse order that you disassembled it. This includes replacing the blade guard and ensuring all parts are securely fastened.
Before using the saw for any projects, perform a test cut. This can be on a scrap piece of wood. The test cut serves two purposes: it helps you ensure the blade is properly installed and gives you an opportunity to check the blade’s performance and the saw’s alignment.
Maintenance and Care
To extend the life of your DWS715 and its blade, regular maintenance is crucial. This includes cleaning the saw after use, especially around the blade area, to prevent dust buildup. Lubricating moving parts can also help in reducing wear and tear.
The blade itself should be stored properly when not in use. This means keeping it in a dry place, away from children and pets, and ideally in a protective case to prevent damage.
Conclusion
Changing the blade on your DWS715 compound miter saw is a task that, while seemingly daunting, is quite manageable with the right guidance. By understanding the importance of blade selection, following the step-by-step replacement process, and maintaining your saw, you can ensure your DWS715 continues to serve you well for years to come. Remember, the key to a successful blade change is patience and attention to detail. With practice, you’ll find that changing the blade becomes second nature, allowing you to focus on the projects that matter most to you.
