The  chop saw is an essential tool for anyone who works with large pieces of metal. The shop saw is often used for cutting down metal bars and other, similar parts, and as a result, the blade may wear down before the rest of the saw, and need replacing. In order to change the blade, you will need to know how to open the area where the blade is positioned, remove the worn blade, and then insert the new one into the device. In order to get the best out of your chop saw, you should be changing your blades as soon as the once you are using starts to show wear, and it is a good idea to have several replacement blades whenever you are doing a big metal working project.

Step 1 - Remove the Old Blade

Firstly, make sure that your chop saw is completely removed from any power sources. If you use a plug-in blade, turn off the power, and then take the connection out of the socket. If you use a battery, remove it from its housing, and take off any wire connections. Once the saw is removed from the power, go back it the machine, and push downwards on the handle of the saw, while simultaneously pulling out the pin of the arm. You should now have the blade completely open before you. Depending on what kind of chop saw you have, you might need to turn the wheel guard until you can see the bolt securing it to the spindle. You will then need to remove the bolt which holds the blade into position with your wrench. Take off the bolt and both washers that hold the blade in place.

Step 2 - Fitting the New Blade

Once you have pulled the old blade completely out of the chop saw, take the new blade, and remove the protective packaging. Make sure that there is no tape left along the edges of the blade's teeth. You should also take the spacing device from the old blade, and insert it into the new one. Place your blade into the middle of the saw, in the same position as the previous one, place the washers over the nut so that the blade is held securely, and then push the bolt onto the nut as tightly as you can. Use your hand to turn the bolt until it is tightly in place.

Step 3 - Finishing Up

Once you have the bolt tightened by hand, secure it by finishing with the wrench, and then turn the wheel so that the spindle is moved slightly to the side. You will then have to close the guard, and reseal the pin of the arm. Lift the handle of the saw, so that the blade assembly is lowered back into position, and then refit the power. Turn on your machine to test the blade.
