# Starting Operation

##

Set the torque presetting ring (2) to the "drilling" symbol.

##

- Only operate the rotational direction switch (7) when the power tool is not in use.

The rotational direction switch (7) is used to change the rotational direction of the power tool. However, this is not possible while the on/off switch (8) is being pressed.

Right rotation: To drill and to drive in screws, press the rotational direction switch (7) through to the left stop.

Left Rotation: To loosen and unscrew screws and nuts, press the rotational direction switch (7) through to the right stop.

##

- Only operate the gear selector (3) when the power tool is not in use.

- Always push the gear selector switch as far as it will go. Otherwise, the power tool may become damaged.

You can preselect two speed ranges with the gear selector (3).

Gear selector switch (3) position | Speed | Torque | Application range
--- | --- | --- | ---
1 | Low | High | For heavy-duty applications: e.g. hammer drilling with large diameters
2 | High | Low | For light-duty applications: e.g. hammer drilling with small diameters

##

To start the power tool, press and hold the on/off switch (8).

The worklight (6) lights up when the on/off switch (8) is lightly or fully pressed, allowing the work area to be illuminated in poor lighting conditions.

The worklight (6) will remain lit for a few seconds after the on/off switch (8) has been released.

##

You can adjust the speed of the power tool when it is on by pressing in the on/off switch (8) to varying extents.

A light pressure on the on/off switch (8) results in a low rotational speed. Increased pressure on the switch causes an increase in speed.
