The green power-ON indicator lamp lights up when the
tool is switched ON. If the indicator lamp is lit but the tool
does not start, the carbon brushes may be worn out, or
the electric circuit or the motor may be defective. If the
indicator lamp does not light up and the tool does not
start, the ON/OFF switch or the mains cord may be
defective.
The red service indicator lamp lights 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.

CAUTION:
Always be sure that the tool is switched off and
•
unplugged before carrying out any work on the tool.
