When it comes to woodworking, having the right tools at your disposal is essential. One of the most important tools is the table saw, and among the top choices for both hobbyists and professionals is the DeWalt 745. This compact, portable table saw is known for its precision and power. However, to maintain optimal performance, it’s crucial to know how to change the blade effectively. This comprehensive guide will walk you through the steps needed to change the blade on your DeWalt 745, ensuring you keep your cuts clean and efficient.
Why You Should Regularly Change Your Table Saw Blade
Changing the blade on your DeWalt 745 is not just a maintenance task; it is a matter of performance and safety. Here are some compelling reasons why blade replacement should be a regular part of your woodworking routine:
- Improved Cutting Performance: A dull blade can lead to poor cuts and increased strain on your motor, resulting in uneven edges and splintering.
- Safety Precautions: Dull blades can cause your saw to work harder, increasing the risk of kickback—a common cause of accidents in the workshop.
Regular blade changes can make a significant difference in the quality of your work while promoting safe practices in your workspace.
Gathering the Required Tools and Materials
Before diving into the process, ensure you have the necessary tools and materials on hand to facilitate a smooth blade change:
Tools Required
- Wrench: A 10mm wrench is typically required to remove the blade.
- Safety Gear: Always wear safety glasses and gloves to protect yourself from any flying debris.
- Clean Cloth: Essential for cleaning the surface and ensuring a tight fit when replacing the blade.
Materials Needed
- Replacement Blade: Ensure you select a compatible blade for the DeWalt 745, ideally one suited for the type of material you’ll be cutting.
Step-by-Step Guide to Changing the Blade on Your DeWalt 745
Now that you have everything ready, let’s get into the nitty-gritty of changing the blade on your DeWalt 745. Follow these steps carefully to ensure a successful blade replacement:
Step 1: Prepare Your Workspace
Before beginning, ensure that your workspace is clean and free of any clutter. Turn off the table saw and unplug it from the power source to prevent any accidental startup.
Step 2: Adjust the Blade Height
Using the height adjustment lever, lower the blade to its lowest position. This will not only make the blade change easier but also is a necessary safety measure.
Step 3: Remove the Blade Guard
The blade guard can be removed by:
- Locating the release lever on the guard.
- Pulling the lever towards you to disengage and lift the guard off the blade assembly.
Step 4: Unlock the Blade
To access the blade, you need to release the blade-lock mechanism. On the DeWalt 745, you will find the blade lock on the left side. Use your wrench to loosen it cautiously.
Step 5: Removing the Old Blade
Once the blade is unlocked, carefully remove the hex nut and any washers holding the blade in place. Set these aside, but keep them safe for reinstallation later.
Step 6: Installing the New Blade
With the old blade removed, take your new blade and ensure you orient it correctly. Pay attention to the direction of the teeth; they should face the front of the saw. Slide the blade onto the arbor carefully.
Step 7: Reattach the Separators and Hex Nut
After positioning the new blade, place the washers back in their original order and secure the hex nut tightly with the wrench. Ensure that the blade is secured firmly to prevent any movement during operation.
Step 8: Reinstall the Blade Guard
After securing the new blade, it’s time to put the blade guard back into place. Ensure it is positioned correctly and that it clicks into place, providing the necessary safety features while operating the saw.
Step 9: Check the Blade Alignment
Once everything is back in place, it’s crucial to check blade alignment. Run your finger along the edge of the blade to ensure that it is parallel to the fence. Adjust, if necessary, to guarantee accurate cuts.
Step 10: Power Up and Test
Plug your table saw back in and power it on cautiously. Perform a test cut on a scrap piece of material to ensure that everything is working correctly and that the blade is cutting smoothly.
Tips for Maintaining Your DeWalt 745 Blade
Once you’ve successfully changed the blade, maintenance will ensure longevity and performance. Here are a few tips:
Regular Cleaning
After several uses, dust and resin can accumulate on blades. Use a specialized blade cleaner and a soft cloth to keep your blade free from buildup. This not only preserves the blade itself but also sustains the quality of your cuts.
Proper Storage
When not in use, avoid leaving the blade exposed. Store it in a protective case or designated area to avoid accidental damage or dulling.

How often should I change the blade on my DeWalt 745 Table Saw?
Changing the blade on your DeWalt 745 Table Saw largely depends on how frequently you use the saw and the types of materials you cut. For general home use, it is recommended to assess the blade after every few projects. If you notice signs of wear, such as dullness, burn marks on the wood, or rough cuts, it’s time to replace the blade.
For professional use or when cutting hardwoods, you may need to change the blade more frequently. A good rule of thumb is to replace the blade every 20 to 30 hours of use. Regular inspections can help ensure that your blade is always performing at its best and contribute to the quality of your work.
What tools do I need to change the blade on my DeWalt 745 Table Saw?
To change the blade on your DeWalt 745 Table Saw, you will need a few basic tools. The most important tool is the provided blade wrench, which is typically included with the saw. This wrench is specifically designed to fit the arbor nut securely, allowing you to loosen and tighten the blade effectively.
Additionally, having a flat surface and a clean, well-lit workspace can make the process much easier. You may also want to use a pair of gloves to protect your hands from any sharp edges and safety glasses to shield your eyes from dust and debris while changing the blade.
Can I use different types of blades on my DeWalt 745 Table Saw?
Yes, you can use various types of blades on your DeWalt 745 Table Saw, depending on your specific cutting needs. The saw is compatible with different blade types, such as ripping blades, cross-cutting blades, and dados. Each blade type is designed for specific applications, so selecting the right one will ensure optimal performance and cut quality.
However, it is essential to ensure that the blade you choose is the correct size for your table saw. The DeWalt 745 typically uses a 10-inch blade, but always double-check the specifications in your user manual. Using an incorrect blade size can damage your saw or lead to subpar cutting performance.
What safety precautions should I take when changing the blade?
Safety is of utmost importance when changing the blade on your DeWalt 745 Table Saw. First and foremost, always disconnect the power source before attempting to change the blade. Unplugging the saw will prevent any accidental starts, which could cause serious injuries. It’s also a good idea to allow the blade to cool down if it has been recently used, as it may be quite hot.
Wearing appropriate safety gear is also crucial. Use gloves to protect your hands from sharp edges, and wear safety glasses to shield your eyes from any flying debris. Ensure your workspace is clean and organized to minimize distractions and accidents. By following these precautions, you can safely change the blade with confidence.
How do I know if my blade is dull?
Identifying a dull blade is essential for maintaining the performance of your DeWalt 745 Table Saw. One of the most noticeable signs of a dull blade is the quality of the cut. If you observe burn marks, jagged edges, or a tendency for the saw to bind or kick back while cutting, it indicates that the blade may need sharpening or replacement.
Another sign is the effort required to push the material through the saw. If you find yourself exerting more force than usual or if the saw makes unusual noises during operation, it’s likely time to replace the blade. Regularly inspecting your blade and monitoring its performance will help you maintain optimal cutting efficiency.
