Auto-stop Brushes
In order to protect the motor, this power tool is equipped with auto-stop
brushes. When the carbon brushes are worn out, the machine switches itself
off.
In this case both brushes must be replaced at the same time with original
brushes by an electrical specialist.
In Case of Malfunction
In case of breakdown, switch the machine off and
disconnect the plug from the mains. Repairs on the electric
parts of the tool may only be done by an electric specialist.
Noise Emission
In addition- there is a service indicator on the motor
cap, which indicates in advance that the machine is
about to shut down due to worn carbon brushes.
After the indicator lights up, you can use the tool for
approximately 1 day. Then the carbon brushes
should be replaced.
