Starting Operation

  • Only operate the rotational direction switch (11) when the power tool is not in use.

The rotational direction switch (11) is used to change the rotational direction of the power tool. However, this is not possible while the on/off switch (12) is being pressed.

Right rotation: To drill and to drive in screws, press the rotational direction switch (11) through to the left stop.

Left Rotation: To loosen and unscrew screws and nuts, press the rotational direction switch (11) through to the right stop.

The torque presetting ring (3) can be used to pre-select the required torque in 20 stages. When the correct setting is used, the application tool will be stopped when the screw is driven flush into the material or once the set torque has been reached. In position the overload clutch is deactivated, e.g. for drilling.

When unscrewing screws, it may be advisable to select a higher setting or the  symbol.

In position , the maximum torque for drilling and screwdriving is achieved.

  • Only operate the gear selector (4) 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 (4).

Application range

1

Low

For heavy-duty applications:

e.g. drilling and screwdriving with large diameters

2

Low

For light-duty applications:

e.g. drilling and screwdriving with small diameters

Drilling
Set the torque presetting ring (3) to the "drilling" symbol to achieve the maximum torque for drilling and screwdriving.

Screwdriving
Set the torque presetting ring (3) to the required torque setting.

To start the power tool, press and hold the on/off switch (12).

The worklight (24) lights up when the on/off switch (12) is lightly or fully pressed, allowing the work area to be illuminated in poor lighting conditions.

You can adjust the speed of the power tool when it is on by pressing in the on/off switch (12) to varying extents.

A light pressure on the on/off switch (12) results in a low rotational speed. Increased pressure on the switch causes an increase in speed.

When used as intended, the power tool cannot be overloaded. If the power tool is overloaded or not kept within the permitted operating temperature range, the speed is reduced or the power tool is switched off. The power tool will not run at full speed again until the permitted operating temperature has been reached.

Activation of the temperature-controlled overload protector is indicated by the LED on the power tool lighting up red.

  • To return to within the permitted operating temperature range, run the power tool at no load or wait until the LED  lights up green again.

When the LED  lights up green, the tool has returned to within the permitted operating temperature range.

The user interface (10) is used to activate and deactivate the precision clutch and for the "KickBack Control" rapid shut-off, as well as for the status indicator of the power tool.

Precision Clutch

The precision clutch stops overlocking when the set torque is reached, thereby reducing clutch wear and the resulting noise.

The precision clutch can be deactivated on the user interface (10) with the precision clutch button (25). The current status is shown via the LED for precision clutch (26) on the user interface (10).

Rapid Shut-off (KickBack Control)

The rapid shut-off function (KickBack Control) gives the user greater control over the power tool and offers them better protection than power tools that do not have KickBack Control. The power tool will switch off if it suddenly and unforeseeably rotates around the drilling axis.

The rapid shut-off is indicated by the LED (21) flashing red, flashing from the worklight (24) and the LED of the KickBack Control (22) lighting up red on the power tool.

To switch the tool back on, release the on/off switch and then press it again.

  • It will no longer be possible to switch the power tool on if the KickBack Control function is faulty. Have the power tool serviced by a qualified repair person using only original replacement parts.

The rapid shut-off function can be deactivated on the user interface (10) with the KickBack Control button (23). If the power tool is not used for longer than 5 minutes or if the rechargeable battery is removed, the rapid shut-off function automatically switches back on. The current status is shown via the KickBack Control LED (22) on the user interface (10).

  • Note: The warning light of the LEDs is not visible from all directions! The warning light is difficult to see in bright sunlight.

Status indicator for power tool 

Meaning/cause

Solution

Green

Status OK

Yellow

Critical temperature has been reached, rechargeable battery is almost empty, or KickBack Control is switched off

Run the power tool at no load and allow it to cool down, replace or charge the rechargeable battery soon, or press the KickBack Control button

Illuminated red

Power tool has overheated or rechargeable battery is empty

Allow the power tool to cool down, or replace or charge the rechargeable battery

Flashing red

Rapid shut-off is triggered

Switch the power tool off and on again

Flashing blue

Power tool is connected to a mobile device or settings are being transferred

In conjunction with the Bluetooth® Low Energy Module GCY 42 / GCY 42 NC, the following connectivity functions are available for the power tool:

  • Registration and personalisation
  • Status check, output of warning messages
  • General information
  • Management
  • Switching the worklight on and off
  • Setting the worklight brightness and afterglow duration
  • Setting the brightness and backlight duration of the user interface
