Start-up
- 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.
The operating mode of the power tool is selected using the mode selector switch (3).
- To change the operating mode, turn the mode selector switch (3) to the required position.
Position for hammer drilling
If the application tool does not start rotating straight away, run the power tool slowly until the application tool starts rotating.
Vario-Lock position for changing the chiselling position
Position for chiselling
Note: Only change the operating mode when the power tool is switched off. The power tool is automatically switched off if you change the operating mode during ongoing operation.
- To switch on the power tool, press the on/off switch (6).
For low temperatures, the power tool reaches the full hammer/impact capacity only after a certain time.
- To lock the on/off switch (6), press and hold it while also pushing the lock-on button (5).
- To switch off the power tool, release the on/off switch (6).
If the on/off switch (6) is locked, press the lock-off button (5) first and then release it.
You can adjust the speed/impact rate of the power tool when it is on by pressing in the on/off switch (6) to varying extents.
Applying light pressure to the on/off switch (6) results in a low rotational speed/impact rate. Applying increasing pressure to the switch increases the speed/impact rate.
You can also control the speed on the user interface and/or via a smartphone app: .
You can lock the chisel in 12 different positions, allowing you to select the optimum working position for each task.
- Insert the chisel into the tool holder.
- Turn the mode selector switch (3) to the "Vario-Lock" position.
- Turn the application tool to the required chisel position.
- Turn the mode selector switch (3) to the "chiselling" position. With this, the tool holder is locked.
The rapid shut-off function (KickBack Control) gives the user greater control over the power tool and offers them better protection than power tools that do not have KickBack Control. If the power tool suddenly and unforeseeably rotates around the drilling axis, it will switch off, the rapid shut-off indicator (12) will light up red and the status indicator (15) will flash red.
- To switch the tool back on, release the on/off switch (6) and then press it again.
