Torque limiter
The torque limiter actuates when torque reaches a cer-
tain level. The motor disengages from the output shaft.
When this happens, the bit stops turning.
CAUTION:
• As soon as the torque limiter actuates, switch
off the tool immediately. This helps to prevent
premature wear of the tool.

► 1. Power-ON indicator lamp (green) 2. Service
indicator lamp (red)
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 immedi-
ately and ask your local service center.
The red service indicator lamp lights up when the car-
bon brushes are nearly worn out to indicate that the tool
needs servicing. After some period of use, the motor
automatically shuts off.
