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.

Abstract: A portable gas-motor-driven cutting implement has a motor unit combined with a fuel tank and supporting a tool carrier. The cutting implement is provided with a curved front handle member extending substantially transversely of the tool carrier and a rear handle at the rear of the motor unit. The front handle member and the rear handle form parts of a rigid, closed supporting frame connected to the motor unit by three widely spaced resilient members, two of which are arranged at the front of the motor unit while the third is arranged at the rear of the motor unit.
