Claim 0:
1. A method for reducing vibrations in a percussion tool, the method comprising:
activating, using an electronic controller of the percussion tool, the motor of the percussion tool;
determining, using the electronic controller, that the percussion tool is in a loaded condition, wherein determining that the percussion tool is in the loaded condition includes determining that a motor current satisfies a current threshold;
operating, using the electronic controller, the motor in accordance with a predetermined profile in response to determining that the percussion tool is in the loaded condition;
determining, using the electronic controller, that the percussion tool is in a no-load condition, wherein determining that the percussion tool is in the no-load condition includes determining that the motor current does not satisfy the current threshold;
operating, using the electronic controller, the motor with reduced speed in response to determining that the percussion tool is in the no-load condition; and
updating the current threshold when switching from the loaded condition to the no-load condition, and when switching from the no-load condition to the loaded condition.
