The switch button projects out and lights in red.
Use a bull point, cold chisel, scaling chisel, etc.
NOTE:
• When using the tool in the symbol mode, the
switch trigger does not work but only the switch
button works.
Torque limiter
The torque limiter actuates when torque reaches a
certain 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.
Indicator lamp

014032
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.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the
tool.

• Use the side handle only when chipping, scaling or
demolishing. Do not use it when drilling in
concrete, masonry, etc. The tool cannot be held
properly with this side handle when drilling.
