# Starting Operation

- Pay attention to the mains voltage! The voltage of the power source must match the voltage specified on the rating plate of the power tool. Power tools marked with 230 V can also be operated with 220 V.

- Products that are only sold in AUS and NZ: Use a residual current device (RCD) with a nominal residual current of 30 mA or less.

##

You can preselect the required speed using the speed preselection thumbwheel (2), even during operation. The higher numbers indicate a high speed, while the smaller ones represent a low speed.

The Constant Electronic keeps the speed at no load and under load virtually consistent, guaranteeing uniform performance.

The electronic soft start limits the torque when the power tool is switched on and increases the service life of the motor.

##

- Make sure that you are able to press the On/Off switch without releasing the handle.

To switch on the power tool, slide the on/off switch (3) forward so that "I" appears on the switch.

To switch off the power tool, slide the on/off switch (3) backwards so that "0" appears on the switch.
