Starting Operation

The rotational direction switch (3) is used to change the rotational direction of the power tool. However, this is not possible while the on/off switch (9) is being pressed.

Right rotation: To drive in screws and tighten nuts, press the rotational direction switch (3) through to the left stop.

Left Rotation: To loosen and unscrew screws and nuts, press the rotational direction switch (3) through to the right stop.

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.

To start the power tool, press and hold the on/off switch (9).

Worklights (10) and (18) light up when the on/off switch (9) is lightly or fully pressed, meaning that the work area is illuminated in poor lighting conditions.

To switch off the power tool, release the on/off switch (9).

The user interface (8) is used to preselect the speed and working mode and to indicate the status of the power tool.

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.

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.
