How to use

Before use, fit a compatible drill or chisel bit securely in the tool’s chuck or accessory holder and ensure the battery is charged and correctly inserted. Select the appropriate speed or mode if the tool offers multiple settings, and position the bit at the marked drilling point. Apply steady pressure and allow the tool’s impact action to do the work; avoid forcing the tool to prevent bit damage or loss of control.
