Abstract
The invention relates to a device for adjustably limiting the maximum speed of an engine powered hand tool controlled by a power-regulating device ( ) located in the handle of the tool. The device makes it possible to optimise the speed of the engine for the job that is to be done. The device consists of a threaded shaft ( ) that is moved by rotating a nut ( ) and a spring ( ). When a higher speed than the selected level is required, is it possible to increase the speed to the maximum speed available by pressing the power-regulating device ( ) with a force that exceeds the force from the spring ( ).
