Speed preselection
With the speed preselection button (19), you can preselect the required speed in three stages. Press button (19) as often as needed until the required setting is indicated in the speed indicator (20). The selected setting will be saved.
You can also preselect the speed using the Bosch Toolbox app.
The required speed depends on the material and the working conditions; it can be ascertained through practical tests.

You can use the button for speed preselection (19) to preselect the required speed, even during operation.
Selecting the working mode
The power tool has two preset working modes A and B (16). You can also programme working modes for different applications and adjust existing modes via the Bosch Toolbox under A and B (16).
To switch between the working modes A and B (16), press the mode button (17).
Predefined working mode (16) | Meaning | Function |
|---|---|---|
A | Auto Slow-down | When using working mode A, the power tool reduces the speed when tightening (impact mechanism in action). The slow-down time can be adjusted via the controls in the Bosch Toolbox app. |
B | Auto Shut-off | When using working mode B, the power tool automatically stops as soon as the screw is screwed all the way in. The shut-off time can be adjusted via the controls in the Bosch Toolbox app. |
Locking/unlocking the user interface
The user interface can be locked and unlocked using the "Lock User Interface" function in the Bosch Toolbox app.
Locking and unlocking through the user interface:
Activate the "(Un-)Lock from tool" function in the Bosch Toolbox app.
The function is now also enabled on the power tool.
To lock or unlock the user interface, press and hold both the mode button (17) and the speed selection button (19) for five seconds.
Note: If the "Lock User Interface" function is activated, the reset to factory settings option on the power tool is automatically deactivated.
