Method for controlling a charging apparatus

14:

• The method as recited in claim 13 wherein the adjustment of the power tool from the first operating mode having at least the first operating characteristic value into the second operating mode having at least the second operating characteristic value takes place in dependence on at least one characteristic value of a material to be machined.

15:

• The method as recited in claim 13 wherein the adjustment of the power tool from the first operating mode having at least the first operating characteristic value into the second operating mode having at least the second operating characteristic value takes place in dependence on the length of the distance of travel.

16:

• The method as recited in claim 13 wherein the adjustment of the power tool from the first operating mode having at least the first operating characteristic value into the second operating mode having at least the second operating characteristic value takes place in dependence on a diameter of a borehole to be produced by the power tool.

17:

• The method as recited in claim 13 wherein the transmission of the at least one signal from the acquisition apparatus to the power tool in dependence on the acquired at least second distance value takes place either directly from the acquisition apparatus to the power tool or by an external apparatus.

18:

• The method as recited in claim 13 wherein the third operating mode corresponds to a deactivated state of the power tool.

19:

• The method as recited in claim 13 wherein a tool of the power tool is operated in a first rotation direction in the first or second operating mode and in a second rotation direction in the third operating mode.

20:

• The method as recited in claim 13 wherein the operating characteristic values of the power tool is a rotation speed value or torque value.

21:

• An acquisition apparatus for performing the method as recited in claim 13 comprising at least one sensor, a control device, an interface device and a communication device.

22:

• The acquisition apparatus as recited in claim 21 wherein the acquisition apparatus is detachably connectable to the power tool.

23:

• The acquisition apparatus as recited in claim 21 wherein the acquisition apparatus is fixedly connected to the power tool.

24:

• A system comprising:
• a power tool and an acquisition apparatus for performing the method as recited in claim 13,
• the power tool including at least a power tool interface and the acquisition apparatus including at least an interface device, wherein the power tool interface and the interface device are able to be fixedly or detachably connected together.
