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

may be worn out, or the controller, the motor or the

carbon brushes are nearly worn out to indicate that the
tool needs servicing. After some period of use, the
