Chainsaw ya batri ndi chowona chonyamula, chomakina chomwe chimadula ndi mano olumikizidwa ndi unyolo wozungulira womwe umayendera kalozera.Amagwiritsidwa ntchito pazochitika monga kugwetsa mitengo, kudula nthambi, kudulira, kudulira, kudula zida zozimitsa moto pozimitsa moto kuthengo ndi kukolola nkhuni.Chainsaw zokhala ndi mipiringidzo yopangidwa mwapadera komanso kuphatikiza maunyolo apangidwa ngati zida zogwiritsira ntchito zojambulajambula ndi mphero za chainsaw.Makatani apadera amagwiritsidwa ntchito podula konkire.Nthawi zina ma tcheni amagwiritsidwa ntchito podula ayezi, mwachitsanzo, zojambulajambula za ayezi komanso ku Finland posambira m'nyengo yozizira .Munthu amene amagwiritsa ntchito macheka ndi wocheka .
Patent yoyambirira kwambiri ya “macheka a unyolo osatha” (chocheka chokhala ndi maunyolo onyamulira mano a macheka ndi kuthamanga mu chimango chowongolera) chinaperekedwa kwa Samuel J. Bens wa ku San Francisco pa January 17, 1905. Cholinga chake chinali kugwa. chimphona redwoods.Makina oyamba onyamula makina adapangidwa ndikuvomerezedwa mu 1918 ndi wopanga mphero waku Canada James Shand.Atalola kuti ufulu wake ufooke mu 1930 luso lakelo linapangidwanso ndi kampani ya ku Germany yotchedwa Festo mu 1933. Kampaniyi tsopano ikugwira ntchito ngati Festool kupanga zida zamagetsi zonyamulika.Zina zofunika zothandizira pazitsulo zamakono ndi Joseph Buford Cox ndi Andreas Stihl;omalizawo anali ndi chilolezo ndipo adapanga makina opangira magetsi kuti agwiritsidwe ntchito pa malo opangira ma bucking mu 1926 ndi makina opangira mafuta mu 1929, ndipo adayambitsa kampani yowapanga mochuluka.Mu 1927, Emil Lerp, yemwe anayambitsa Dolmar, anapanga makina osindikizira a petulo oyamba padziko lonse lapansi ndi kuwapanga mochuluka.
Nkhondo Yachiŵiri Yapadziko Lonse inasokoneza kupereka kwa macheka a unyolo ku Germany ku North America, motero opanga atsopano anatulukira kuphatikizapo Industrial Engineering Ltd (IEL) mu 1947, amene anatsogolera Pioneer Saws.Ltd komanso gawo la Outboard Marine Corporation, wopanga wakale kwambiri wa ma chainsaws ku North America.
McCulloch ku North America anayamba kupanga makina osindikizira mu 1948. Zitsanzo zoyambirira zinali zolemera, zida za anthu awiri okhala ndi mipiringidzo yaitali.Nthawi zambiri macheka a unyolo anali olemera kwambiri moti anali ndi magudumu ngati ma dragsaws .Zovala zina zimagwiritsa ntchito mizere yoyendetsedwa kuchokera kugawo lamagetsi lamagetsi kuti ayendetse zitsulo zodula.
Nkhondo yachiŵiri ya padziko lonse itatha, kukonza bwino kwa ma aluminiyamu ndi kamangidwe ka injini kunapeputsa macheka a unyolo moti munthu mmodzi akanatha kuwanyamulira.M'madera ena antchito otsetsereka (matcheni) asinthidwa ndi odula ndi okolola .
Macheka ocheka matabwa aloŵa m’malo mwa macheka wamba opangidwa ndi anthu m’nkhalango.Amabwera m'miyeso yambiri, kuyambira macheka amagetsi ang'onoang'ono ogwiritsidwa ntchito kunyumba ndi m'munda, mpaka macheka akuluakulu "obaya matabwa".Mamembala a magulu ankhondo amaphunzitsidwa kugwiritsa ntchito macheka monga momwe amachitira ozimitsa moto polimbana ndi moto m'nkhalango komanso kutulutsa mpweya woyaka moto.
