Using the Bosch 18CG - 45E cutting guard is a breeze. First, make sure your grinder is turned off and unplugged. Then, since it's a tool - free design, you can easily attach the guard to your 4 - 1/2 inch small angle grinder that's compatible with it. When you're ready to use the grinder, the guard will protect you by covering 180 degrees of the grinding disk. It will also catch any wheel fragments if the wheel breaks. As for maintenance, after each use, wipe the guard with a clean cloth to remove any dust or debris. Check the guard regularly for any signs of wear or damage, especially after a wheel burst. If you notice any issues, it's best to replace the guard to ensure your safety.
