A gas-engine-powered handheld working machine (10) has a working unit driven by a 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) lying flat 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 extends substantially perpendicular to the horizontal plane.本發明揭示一種燃氣引擎動力手持式作業機(10),燃氣引擎動力手持式作業機(10)具有由一引擎驅動的一作業單元,該引擎能以自一蓄氣筒(21)供應之一氣體燃料運轉。該蓄氣筒經配置使得當該手持式作業機佈置於一正常靜止位置中,而其中該手持式作業機安置於一水平面上(34)上且一機體(14)之一底面(14a)平置於該水平面上時,該蓄氣筒佈置於一大體上垂直位置中且一排出噴嘴(23)被引導向下同時該蓄氣筒之一中心軸(35)大體上垂直於該水平面延伸。10...燃氣引擎動力手持式作業機(除草機)14...機體14a...底面21...蓄氣筒23...排出噴嘴32...筒蓋34...水平面35...中心軸36...筒殼體43...選擇器旋鈕64...作業桿P2...打開位置P5...閉合位置T1...本位
