Using your Makita 723080 - A - 5 reciprocating saw blades is easy. First, make sure your saw is turned off and unplugged. Then, securely attach the blade to your saw according to the saw's instructions. When cutting, keep a firm grip on the saw and let the blade do the work. Try to cut at a steady pace. Remember, these blades are great for cutting wood, metal, and plastic. When not in use, store the blades in a dry place to prevent rust. If the blade gets dull, it's time to replace it. Don't force the blade through a tough cut, as this can damage both the blade and your saw. With proper use and care, these blades will serve you well for a long time.
