Using the Metabo W26 - 230 MVT 9 angle grinder is straightforward. First, make sure to install the guard and side handle properly. The side handle can be placed in one of the three available positions according to your comfort. When starting the grinder, always check that the safety switch is in the correct position to avoid accidental starts. During use, the swiveling main handle will give you better control, especially when cutting. Remember, the VibraTech side handle reduces vibrations, so hold it firmly to protect your hands. After use, clean the grinder to prevent dust from building up inside the motor. The auto - stop carbon brushes will protect the motor, but it's a good idea to check them periodically. If you need to adjust the guard, you can do it without tools, but ensure it's securely mounted to keep you safe.
