Starting Operation

  • Only operate the rotational direction switch (9) when the power tool is not in use.

The rotational direction switch (9) is used to change the rotational direction of the power tool. However, this is not possible while the on/off switch (10) is being pressed.

Right rotation: To drill and to drive in screws, press the rotational direction switch (9) through to the left stop.

Left Rotation: To loosen and unscrew screws and nuts, press the rotational direction switch (9) through to the right stop.

Drilling

GSR 185-LI
Set the torque presetting ring (3) to the "drilling" symbol.

GSB 185-LI
Set the operating mode presetting ring (4) to the "drilling" symbol.

Screwdriving

GSR 185-LI
Set the torque presetting ring (3) to the required torque.

GSB 185-LI
Set the operating mode presetting ring (4) to the "screwdriving" symbol.
Set the torque presetting ring (3) to the required torque.

Impact drilling

GSB 185-LI
Set the operating mode presetting ring (4) to the "impact drilling" symbol.

To start the power tool, press and hold the on/off switch (10).

The LED (8) lights up when the on/off switch (10) 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 (10).

You can adjust the speed of the power tool when it is on by pressing in the on/off switch (10) to varying extents.

A light pressure on the on/off switch (10) results in a low rotational speed. Increased pressure on the switch causes an increase in speed.

The torque presetting ring (3) can be used to pre-select the required torque in 20 stages. Once the set torque has been reached, the rotating motion of the application tool will be stopped.

  • Only operate the gear selector (5) when the power tool is not in use.

First gear:

Low speed range; for working with a large drilling diameter or for screwdriving.

Second gear:

High speed range; for working with a small drilling diameter.

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

When used as intended, the power tool cannot be overloaded. In the event of overloading or the temperature rising outside the permitted operating temperature range, the speed will be reduced. The power tool will not run at full speed again until the permitted operating temperature has been reached.

The drill spindle, and therefore the tool holder (1), are locked when the on/off switch (10) is not pressed.

This enables screws to be screwed in even when the battery (6) is empty and allows the power tool to be used as a screwdriver.
