Using the DeWalt DCS3711 Band Saw Blade Guard is easy. First, make sure your band saw is turned off and unplugged. Then, attach the guard to your DCS371 20V MAX* Type 2 Band saw. You can operate it with one hand, which is really convenient. When using the saw, the guard will keep the blade in place and protect you from accidental contact. Just remember to always wear safety goggles and follow all safety rules. As for maintenance, regularly check the guard for any signs of damage. If it gets dirty, you can clean it with a dry cloth. Store it in a dry place when not in use to prevent rusting. This way, your guard will serve you well for a long time.
