Using these Bosch jig saw blades is a breeze. First, make sure your jigsaw is turned off and unplugged. Insert the T - shank blade into the blade holder of your jigsaw until it locks securely. When you're ready to cut, start with a slow speed, especially if you're new to using these blades. As you get the hang of it, you can increase the speed for faster cuts. Remember, these blades are great for straight - line cutting of medium to thin metals, so try to keep your cuts as straight as possible. When cutting metal, it's important to use a proper lubricant. This helps the blade cut smoothly and also extends its lifespan. After each use, wipe the blade clean with a dry cloth to remove any metal shavings or debris. Store the blades in a dry place to prevent rusting. If you notice the blade isn't cutting as well as it used to, it might be time to replace it with a new one from the 100 - piece pack you have.
