Inde, osakhala akatswiri omwe ali omasuka kugwira ntchito ndi makina opangira ma tcheni amatha kugwiritsa ntchito zitsanzo zolemetsa zokhala ndi mipiringidzo yotalika pakati pa 16-20 mainchesi. Ma chainsaws awa ndi oyenera kudula mitengo ikuluikulu pamtunda wamtunda kapena wakumidzi.

Eni nyumba omwe amacheka mwa apo ndi apo chaka chonse atha kugwiritsa ntchito macheni amagetsi kapena oyendetsedwa ndi batire okhala ndi mipiringidzo yayitali mainchesi 14. Matcheni awa ndi okwanira pa zosowa zawo.

Inde, macheka ang'onoang'ono amatha kudula mitengo yayikulu podutsa maulendo angapo. Mwachitsanzo, 16-inch kalozera bar akhoza kudula mitengo kawiri utali wake. Komabe, mphamvu ya injini ya chainsaw iyenera kuganiziridwa kuti iwonetsetse kuti imatha kugwira zipika zazikulu. Podula mitengo ya 32-inch pafupipafupi, tikulimbikitsidwa kugwiritsa ntchito makina olemera a gasi.

Malo angakhale chinthu choyenera kuganizira. Ngati mukudula mitengo yaying'ono m'mimba mwake ndipo kuyenda sikudetsa nkhawa, makina amagetsi amagetsi angagwiritsidwe ntchito. Komabe, ngati mukufuna ufulu woyenda, ma tcheni oyendetsedwa ndi batire angakhale abwino. Ngati mukufuna kugwira ntchito kwa nthawi yayitali pakudula mitengo yolemetsa, ma soya a petulo amakhala olimba ndipo amatha kugwira ntchito pazinthu zazikulu.

Ayi, oyamba kumene ayenera kuyamba ndi macheka ang'onoang'ono ndipo pang'onopang'ono apite ku zitsanzo zaukatswiri, zokhala ndi mpweya. Makatani okhala ndi mipiringidzo ya mainchesi 18 kapena kuchepera, makamaka mainchesi 10-12, amalimbikitsidwa kwa oyamba kumene. Makina opangira magetsi kapena batire ndi oyeneranso kwa ogwiritsa ntchito osadziwa.

Pa ntchito zodulira mopepuka monga kudulira, kudulira, ndi kuyeretsa mitengo yaying'ono kapena nthambi, makina opangira magetsi kapena batire okhala ndi mipiringidzo yayitali mainchesi 10-14 ndi oyenera. Makataniwa ndi osavuta kugwiritsa ntchito nthawi ndi nthawi ndi eni nyumba.

Podula mitengo yayikulu, cholozera chaukadaulo chokhala ndi kalozera wa mainchesi 20 kapena kuposerapo chikulimbikitsidwa. Matcheniwa ndi amphamvu ndipo amapangidwa kuti azigwira ntchito zolemetsa.

Kutalika kwa kalozera wa chainsaw ndiye chinthu chofunikira kwambiri chomwe muyenera kuganizira. Mipiringidzo yayitali imakhala yothandiza kwambiri podula mitengo yokhala ndi mainchesi akulu. Kuphatikiza apo, kusuntha kwa injini ndi mphamvu zamahatchi kuyenera kuganiziridwanso pantchito zodula kwambiri.
