With the speed preselection button (15), you can preselect the required speed in three stages. Press button (15) as often as needed until the required setting is indicated in the speed indicator (16). The selected setting will be saved.

You can also preselect the speed using the Bosch PRO360 app.

The required speed depends on the material and the working conditions; it can be ascertained through practical tests.

| Basic speed setting at level
--- | ---
1 | 2 | 3
[min–1] | [min–1] | [min–1]
Number of speed settings |  |  |
3 | 0–800 | 0–1500 | 0–2400

You can use the button for speed preselection (15) to preselect the required speed, even during operation.

The user interface can be locked and unlocked using the "Lock User Interface" function in the Bosch PRO360 app.

## Locking and unlocking through the user interface:

Activate the "(Un-)Lock from tool" function in the Bosch PRO360 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 (13) and the speed selection button (15) 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.

##

The power tool has two preset working modes A and B (12). You can also programme working modes for different applications and adjust existing modes via the Bosch PRO360 app under A and B (12).

To switch between the working modes A and B (12), press button (13).

To leave the working modes, press the button for speed preselection (15).
