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 defective.

When the indicator lamp lights up but the tool does not start even the tool is switched on, the carbon brushes may be worn out, or the controller, the motor or the ON/OFF switch may be defective.

If above symptoms occur, stop using the tool immediately and ask your local service center.

The red service indicator lamp lights up when the carbon brushes are nearly worn out to indicate that the tool needs servicing. After some period of use, the motor automatically shuts off.
