Abstract

A regulating arrangement for internal combustion engine-driven tools, such as power saws of the type provided with a handle piece, from the one side of which a finger grip projects connected to the throttle valve of the engine and from the other side of which a middle hand grip and a thumb grip project. The middle hand grip, when the tool is in use, is adapted to release a lock for the finger grip preventing an unintentional opening of the throttle, while the thumb grip is adapted to make it possible to hold the finger grip in a middle position. The middle hand grip and the thumb grip include a common hooking piece, which includes a number of fingers projecting from a rear support of the same, one of said fingers including a forwardly directed hook and the other a backwardly directed dog, which selectively can be brought into engagement and disengagement with a projection on the finger grip.
