Place the saw on its side, with the blades cutting edge away from you. You will notice a black button on that side, toward the bottom of the saw, and just behind the blade. The button is usually black and is on the saw body, not on the blade.
Push that button down. This releases the the blade mechanism that will allow you to push the blade away from you. The blade will push away to approximately a 90 degree angle, then just grasp the blade and it will loosen from the saw.
To insert a new blade, just reverse the process. the new blade will slide over the oval retainer. Make sure it is seated properly, then just pull it toward you until it is seated. If the blade doesn't fit over the oval retainer you will have to rotate the retainer with a small wrench or pliers. Push the black button in and turn the oval retainer so it will line up with the slot on the blade.
