Using the Bosch GWS10 - 45PE angle grinder is easy. First, attach the auxiliary handle and adjust the guard to your preferred working angle. Then, plug in the grinder and switch it on using the paddle switch. You can lock the switch on for continuous use. When grinding or cutting, hold the grinder firmly with both hands, one on the main body and the other on the auxiliary handle. Make sure to keep the grinding wheel in good contact with the surface you're working on. As for maintenance, regularly check the Service Minder brushes. When they indicate that maintenance is needed, stop using the grinder. Keep the grinder clean by blowing out dust from the air vents. Also, avoid using the grinder in extremely dusty environments to extend its lifespan. Remember to always wear safety goggles and appropriate protective gear when using this tool.
