Start-up

The operating mode of the power tool is selected using the mode selector switch (5).

• To change the operating mode, turn the mode selector switch (5) to the required position.

For low temperatures, the power tool reaches the full hammer/impact capacity only after a certain time.

You can adjust the speed/impact rate of the power tool when it is on by pressing in the on/off switch (9) to varying extents.

Applying light pressure to the on/off switch (9) 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 16 different positions, allowing you to select the optimum working position for each task.
