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
Fig.7
The green power-ON indicator lamp lights up when the
tool is plugged. If the indicator lamp does not light up,
the main cord or the controller may be defective. The
indicator lamp is lit but the tool does not start even if 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.
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.
Installing side grip (auxiliary handle)

CAUTION:
Always use the side grip to ensure operating safety
•
when drilling in concrete, masonry, etc.
The side grip swings around to either side, allowing easy
handling of the tool in any position. Loosen the side grip
by turning it counterclockwise, swing it to the desired
position and then tighten it by turning clockwise.
