Using the Makita 9557NB2 angle grinder is quite straightforward. First, make sure you choose the right power source, either AC or DC, using the switch on the tool. Then, check the wheel and use the spindle lock to change it if needed. When you're ready to start, hold the grinder firmly by the 2 - 1/2 - inch barrel - grip handle. Turn it on and start grinding at a steady pace. Remember to wear safety goggles and gloves to protect yourself from debris. As for maintenance, after each use, clean the grinder to remove dust and debris. The labyrinth construction and zigzag varnish already do a great job of protecting the motor, but regular cleaning will keep it in top shape. Also, periodically check the wires for any signs of damage. If you notice any issues, stop using the tool and get it checked by a professional.
