Method for indicating a misuse of a machine tool

6:

• A method for controlling in an open and closed loop a power tool including a power tool housing, a control unit, a drive, a tool fitting, and an output device, the method comprising steps of
• detecting at least one acceleration value via at least one acceleration sensor;
• sending at least one signal to the output device for the purpose of outputting at least one acoustic and/or visual warning signal if a detected acceleration value reaches a threshold value saved in the memory device, or sending at least one signal from the control unit for adjusting the drive from a first operating state into a second operating state.

7:

• The method as recited in claim 6 wherein the signal is sent from the control unit for adjusting the drive from the first operating state into the second operating state and a first speed value is set in the first operating state for the drive, and a second speed value is set in the second operating state for the drive, wherein the second speed value is higher than the first speed value, and wherein the operating state alternates between the first and the second state for a predetermined period of time or frequency.

8:

• The method as recited in claim 6 wherein the signal is sent from the control unit for adjusting the drive from the first operating state into the second operating state and wherein a first speed value is set in the first operating state for the drive, and a second speed value is set in the second operating state for the drive, wherein the second speed value is at least 50% higher than the first speed value.

9:

• The method as recited in claim 6 wherein the power tool a handheld power tool.

11:

• The system as recited in claim 10 wherein the rechargeable battery includes at least one battery output device connected to the control device and to the acceleration sensor.
