Abstract

A power tool comprising a controller for controlling the operation of the power tool wherein the controller is configured to control operation of the power tool in a default mode and in a low-noise mode, wherein; the controller, is configured to control operation of the power tool in the low-noise mode on basis of predetermined settings that are selected such that the noise output from the power tool in the low-noise mode is lower than the noise output from the power tool in the default mode.

Claims (23)

1. A power tool comprising a controller for controlling the operation of the power tool, wherein the controller is configured to control operation of the power tool in a default mode and in a low-noise mode, wherein;

the controller, is configured to control operation of the power tool in the low-noise mode on basis of predetermined settings that are selected such that the noise output from the power tool in the low-noise mode is lower than the noise output from the power tool in the default mode, wherein

the controller is configured to receive low-noise activation input from a low-noise activation means and on basis of the low-noise activation input activate a low-noise state of the controller in which the controller controls operation of the power tool in the low-noise mode, wherein

the low-noise activation input is the time-of-day and/or the date and/or the geographic position of the power tool.

2. The power tool according to claim 1 wherein the low-noise activation input is a signal from a low-noise activation means that is remote from the power tool.

3. The power tool according to claim 1 , wherein the controller is configured to receive the predetermined settings for operating the power tool in the low-noise mode from a source that is remote to the power tool.

4. The power tool according to claim 1 , wherein the controller comprises the predefined settings for operating in the low-noise mode.

5. The power tool according to claim 1 , wherein the power tool comprises a motor and wherein the controller is configured to control the operation of the motor.

6. The power tool according to claim 5 , the wherein motor is an electrical motor.

7. The power tool according to claim 1 , wherein the power tool is a garden tool such as a blower or a trimmer or a hedge trimmer or a chainsaw.

8. The power tool according to claim 1 , wherein the predetermined settings for operating in the low-noise mode are selected from motor speed and/or motor acceleration and/or motor power and/or lubrication feed.

9. The power tool according to claim 1 , comprising a low-noise component.

10. The power tool according to claim 9 , wherein the low-noise component is an Active Noise Cancellation unit.

11. The power tool according to claim 9 , wherein the power-tool is a leaf-blower and wherein the low-noise component is an exhaust pipe comprising a layer of sound dampening material.

12. The power tool according to claim 9 , wherein the power-tool is a leaf-blower and wherein the low-noise component is a layer of sound dampening material arranged at an air intake of the leaf blower.

13. A system for operating a power tool comprising:

at least one power tool according to claim 1 , and;

a remote device, wherein

the remote device and the power tool are communicatively connectable and wherein the remote device is configured to transmit low-noise activation input to the controller of the at least one power tool.

14. A method for operating a power tool comprising a motor and controller for controlling the operation of the tool, wherein the controller is configured to control operation of the power tool in a default mode and in a low-noise mode, said method comprising the steps:

receiving low-noise activation input from a low-noise activation means and on basis of the low-noise activation input activate a low-noise state of the controller, wherein the low-noise activation input is the time-of-day and/or the date and/or the geographic position of the power tool and;

on basis of the low noise activation input activating a low-noise state of the controller in which the controller controls operation of the power tool in the low-noise mode, and;

operating the controller to control operation of the power tool on basis of predetermined settings that are selected such that the noise output from the power tool in the low-noise mode is lower than the noise output from the power tool in the default mode.
