How To Change Blade, Step by Step

Remove or demount the protective shroud around the device

1. The first and most important step in this is to remove or demount the protective shroud around the device. You must know that this process can be done without this step. Nonetheless, this step is of excellent importance as it can save you a lot of hassle and ensure that this is safe. The whole process is quite simple as it can get. You must begin by unscrewing everything that holds the protective shroud in place around the blade. You can use your hand or a wrench to do the same. This is usually a single or two screws and is not very difficult to achieve.

Demounting the blade itself

2. The second step is to demounting the blade itself. With the protective shroud off, you have better access to each of the components and screws of the miter saw. You can start with the supporting screws as doing this is easier. You can find an index that is placed exactly parallel and helps prevent the axis from rotating by itself. You can press and hold this down before unscrewing the other remaining screws as it helps with not loosening the axis itself and creating a hassle

3. If there is any extra pressure in doing this step, do not use extra force and create unbalance tightness in the device that causes issues with it later on. Do it gently and use any supporting device like a wrench or other tool to keep it easy and steady.

Installing a new blade

4. Now comes the fun part of this - installing the new blade. This is relatively a hassle-free task and you can do this quite easily. Unwrap the new disc from its packaging beforehand and place it carefully on any flat surface so that it does not tilt to one side and get scratched. Take the new disc and put it on the axis of the device. The disc should be parallel to the index and at a 90-degree angle. You need not worry if it is slightly off. It will come into its standard position when you begin tightening the screw. But make sure you don’t tighten it too much as it may affect the rotations per minute of the device.

5. You should always remember it to unplug it before installing the blade. While this may seem like common sense, there are few people who mess with a “live” machine. Such instances can lead to tragic events and you should ensure that you follow all safety precautions

6. You should also consider wearing light protective gear such as gloves. There is a small chance that you might scrape your hand against the sharp blade while changing it. This may happen especially while tightening the arbor or mounting the blade.

7. Always ensure that the main bolt is properly screwed and is tight as you think it is. A lot of people make the mistake of hand screwing it which does not give it the right amount of tightness that it should possess. Needless to say, use a wrench and tighten all screws properly. Otherwise, it may affect the rotations per minute and the overall performance of the device

Testing after changing new blade

8.  You must ensure that each of the knobs and screws is working properly by connecting it to a power source before actually using it on something. This testing may lead you to find other faults that you may rectify before actually doing the work.

9. Another issue that keeps cropping up with changing the blades on a miter saw such as the Dewalt DWS780 is that there may be faulty screws or rusted nuts that you are reusing to put back the blade together. To prevent the loss of efficiency and the overall damage of the device, use a lubricant. You can use WD40 lubricant which is affordable, cheap and very effective to get rid of the rusty nuts and bolts in changing the blade of the Dewalt DWS780 miter saw.

Final step

Finally, this is the end of the comprehensive guide of changing the blade of a miter saw. While this seems fun and easy, the task requires extreme focus, dedication, and attention to detail. You need not be a professional carpenter or a handyman to do this simple task. However, we suggest you look up this tutorial again or watch any suggestive videos to get the hang of it before actually trying it out yourself. You should also know that this is a relatively easy task to accomplish and once you get the hang of it, there is no turning back in attaching a new blade for the Dewalt DWS780.

Always use light protective wear and ensure that the sharp edges of the new or old blade are away from your body. Ensure you purchase the most quality of blades. You can always call up Dewalt or their subsidiaries to get a solid check on the right blades to use.
