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

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

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

Side handle

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.
The side handle can be swung 360° on the vertical and
secured at any desired position. It also secures at eight
different positions back and forth on the horizontal. Just
loosen the clamp nut to swing the side handle to a
desired position. Then tighten the clamp nut securely.
