If you want a visual image of any of the key DeWalt parts described below, you should simply Google its name, e.g. DeWalt Blade Guard, and click the “Images.”
1. The blade guard
The blade guard is the blade cover. It is the part of the compound miter saw that covers the blade to protect the user from getting cut or hurt when operating it. The compound saw blade is typically very sharp and becomes very hot after a cutting job. So the blade guard is important to make sure it does not cut or burn your fingers and hands. Before operating your blade guard, you must always make sure it is working perfectly.
2. The bracket screw
The blade guard in DeWalt compound saws is usually fastened to the blade arm using a screw. This screw is known as the bracket screw.
3. The spindle lock
The blade of your DeWalt compound saw can rotate even when your saw is not powered. This can result in cuts when you are replacing it or maintaining the saw in general. This is the reason why the spindle lock exists. The spindle lock is a mechanism that locks the blade preventing it from freely rotating. It is important to make sure the spindle lock is engaged to avoid hurting yourself when removing the blade or doing compound saw maintenance.
4. The blade screw
The blade screw is the screw that holds the blade in place. It is what you need to loosen using a wrench to be able to remove and change your DeWalt blade.
Steps to follow to change your DeWalt miter saw blade
Now that you have familiarized yourself with the main parts of the DeWalt compound miter saw, it is time to learn the exact steps you need to follow to remove and change its blade. One more thing that is important to mention before we look at the steps is that it is key to change your DeWalt blade with a similar type and size blade if you want the same cutting performance.
Without any further delay, here are the steps you need to follow to change your DeWalt blade.
Step 1: Wear your protective glasses and your heavy-duty work gloves
Before you start changing your DeWalt blade, you need to wear protective glasses and heavy-duty work gloves. Wearing these two things is important to ensure your safety during the blade-changing process.
Step 2: Shut down your compound miter saw
As is the case when repairing or maintaining any power tool, you must shut down your compound miter saw before you start changing its blade. Shut it down and completely disconnect it from your power supply by unplugging it. This will ensure it doesn’t accidentally start when changing its blade.
Step 3: Unscrew the bracket screw and lift your blade guard
After shutting down and unplugging your compound miter saw, you should loosen the bracket screw to lift your blade guard. Your blade guard is held in place by the bracket screw. Once you loosen the bracket screw a bit using the blade wrench, you should be able to lift it (the blade guard) out of the way. After lifting it, let it rest on the bracket screw to expose the blade screw.
Step 4: Unscrew the blade screw
After exposing the blade screw, all you need to do to remove your blade is to unscrew the blade screw. Before you do this, you should engage the spindle lock to prevent the blade from moving as you are unscrewing it. Unscrew the screw in the clockwise direction to remove it and the blade.
Step 5: Make sure you do not lose the parts
When you unscrew the blade screw, you will not only remove the screw and the blade but also a few other important parts of your compound miter saw. Make sure you do not lose the parts by putting all of them in one place.
Step 6: Install the new blade
After removing the old blade, attach your new blade and the components back to your power tool using the blade screw. Make sure your screw back on everything that came loose when you unscrewed the blade screw. Because if something is amiss, your saw will not work correctly.
Step 7: Finish the job
After you are done screwing your new blade and your compound saw parts back on, you should finish the job by ensuring you have properly secured the blade and the important parts around it. You should then return the blade guard back to its place and ensure it is also properly secured.
As you can see above, changing a DeWalt blade is a straightforward process. You just have to gather the right tools, know the key parts of your saw, and follow the steps above to do it correctly.
