Kufotokozera Zamalonda

Ma valavu a manja a 4H opangidwa ndi pneumatic amapangidwa kuti azipereka chiwongolero chowongolera komanso chodalirika cha kayendetsedwe ka mpweya m'mafakitale osiyanasiyana opanga makina. Zopezeka m'njira zonse za 3/2 ndi 5/2 njira, mavavuwa amayendetsedwa ndi zotengera zamanja kapena zogwirira zozungulira, zomwe zimathandiza kusinthana mwachangu komanso moyenera popanda kufunikira kwamagetsi kapena ma siginecha oyendetsa ndege. Kamangidwe kake kolimba komanso kugwira ntchito kwake kosavuta kumawapangitsa kukhala abwino kukonzanso, kutseka kwadzidzidzi{7}}, ndi kutulutsa ntchito pamanja pamakina a mpweya. Monga katswiri wothandizira pneumatic ku China, timapereka ma valavu apamanja a 4H okhala ndi mitengo yampikisano komanso kupezeka kosasunthika kuti zithandizire zosowa zanu zopanga ndi zida padziko lonse lapansi.
