What You Will Need
Before changing the blade, gather the necessary tools and safety gear. Here’s a concise list:
- Safety Glasses or Face Shield
- Hearing Protection
- 5/32” Allen Wrench (or the specific size for your model)
- New Mitre Saw Blade
Choosing the right blade is essential—consider the material you’ll be cutting and the finish you desire. DeWalt offers a variety of blades designed for specific applications, including cross-cutting, ripping, and finishing.
Steps to Change the Blade on a DeWalt 12 Mitre Saw
Changing the blade on a DeWalt 12 Mitre Saw is a straightforward process that can typically be completed in under 10 minutes. Follow these detailed steps to make the replacement hassle-free.
Step 1: Safety First
Before you begin, ensure you adhere to these safety precautions:
- Disconnect the power: Unplug the saw from the outlet to prevent accidental operation.
- Wear safety gear: Put on your safety glasses and hearing protection to shield yourself from debris and noise.
By prioritizing safety, you will create a secure workspace.
Step 2: Locate the Blade Guard and Locking Mechanism
Identify the blade guard and the arbor locking button. The blade guard will cover the blade when not in use, and the arbor locking button is essential for keeping the blade in place during removal.
Step 3: Engage the Arbor Lock
Press the arbor locking button. This locks the blade in place and prevents it from spinning while you remove it.
Step 4: Remove the Blade Nut
Using the 5/32” Allen wrench, loosen the blade nut by turning it counterclockwise. Depending on your saw model, this step might involve unscrewing a few screws before removing the blade.
Make sure to keep track of the nut and any associated washers, as you will need them for reinstallation.
Step 5: Remove the Old Blade
After loosening the nut, gently lift the blade off the arbor. Be careful during this process to avoid cutting yourself.
Step 6: Install the New Blade
Now it’s time for the most crucial part: installing your new blade. Make sure it is oriented correctly, with the teeth pointing in the right direction for the rotation of the saw. Typically, the teeth should point toward the front of the saw when mounted.
Step 7: Replace the Blade Nut
With the new blade in position, replace the blade nut and tighten it securely. Turn the nut clockwise until it is snug. It’s important not to overtighten, as this could damage the blade or the saw.
Step 8: Test the Blade
Before plugging in your saw, give the blade a visual inspection to ensure everything is tightened correctly and that the blade rotates smoothly. Once you’re satisfied, plug the saw back into the power outlet.
Step 9: Make a Test Cut
After installing the blade, make a test cut on a scrap piece of wood. Ensure the saw operates smoothly, and evaluate the quality of the cut. If the cut is clean, you’ve successfully changed the blade!
Maintaining Your DeWalt 12 Mitre Saw Blade
After replacing your blade, consider these tips to maintain its lifespan and effectiveness:
Cleaning the Blade
Regularly clean the blade to remove resin, pitch, and debris buildup. Use a soft brush and a non-corrosive cleaner, and always wipe the blade dry before reinstalling it.
Storage
Store your blades in a safe, dry location. Use blade guards to protect the cutting edges and minimize the risk of accidents. A dedicated storage case can also help keep your workspace organized and free of hazards.
Rest Check
Periodically inspect your newly installed blade for signs of wear – such as dullness, chips, or damage. Depending on your usage, you may need to replace the blade more frequently.
