Abstract

A gas-engine-powered handheld working machine (10) has a working unit driven by an engine capable of running on a gas fuel supplied from a gas cartridge (21). The gas cartridge is arranged such that when the handheld working machine is disposed in a normal rest position where the handheld working machine is placed on a horizontal plane (34) with a bottom surface (14a) of a machine body (14) lyingflat on the horizontal plane, the gas cartridge is disposed in a substantially vertical position with a discharge nozzle (23) directed downwards while a central axis (35) of the gas cartridge extendssubstantially perpendicular to the horizontal plane.

Description

technical field [0001] The present invention relates to a hand-held working machine having a working unit driven by a gas engine capable of running on gas fuel supplied from a gas cylinder. Background technique [0002] A related type of hand-held work machine includes a bush cutter equipped with a power source formed by a gas engine. A typical example of such a gas engine-driven bush cutter is disclosed in Japanese Utility Model Application Publication (JP-U-A) No. 03-116,751. The above-disclosed bush cutter includes a gas cylinder bay associated with the gas engine and configured to hold the gas cylinders in a generally horizontal position. In operation, liquefied gas fuel stored in the gas cylinder is supplied from the discharge nozzle of the gas cylinder to the engine to drive the engine, and the engine rotates a cutting blade as a working unit, thereby performing a desired bush cutting operation. [0003] In the bush cutter shown in JP-U 03-116,751, the gas cylinder i...
