The green power-ON indicator lamp lights up when the tool is plugged in. If the indicator lamp does not
light up, the mains cord or the controller may be malfunctioning. The indicator lamp is lit but the tool does
not start even if the tool is switched on, the carbon brushes may be worn out, or the controller, the motor

The red service indicator lamp flickers up when the carbon brushes are nearly worn out to indicate that the
tool needs servicing. After approx. 8 hours of use, the motor will automatically be shut off.
