2 For chipping, scaling or demolition operations, depress the lock button and
rotate the change lever so that the pointer points to the
point, cold chisel, scaling chisel, etc.
CAUTION:
• Do not rotate the change lever when the tool is running under load. The
tool will be damaged.
• To avoid rapid wear on the mode change mechanism, be sure that the
change lever is always positively located in one of the two action mode
positions.
Torque limiter
The torque limiter will actuate when a certain torque level is reached. The
motor will disengage from the output shaft. When this happens, the bit will stop
turning.
CAUTION:
• As soon as the torque limiter actuates, switch off the tool immediately.
This will help prevent premature wear of the tool.
Indicator lamp
003138
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.
Side handle
003139
CAUTION:
• 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.
