Mchira wa msomali woboola mchira nthawi zambiri umakhala ngati mchira woboola kapena mchira wakuthwa, womwe umakhala pamsika mwachangu chifukwa chogwiritsa ntchito mosavuta komanso mosavuta. Msomali wobowola ungagwiritsidwe ntchito pobowola mabowo pazinthu zosiyanasiyana zofunikira kuti muzindikire kulumikizana mwachangu ndi msonkhano, uli ndi mphamvu yolimba, sikophweka kumasula ndikugwa, ndikosavuta komanso kosavuta kugwiritsa ntchito, ndipo ili ndi chitetezo chambiri. Ntchito zomanga ndi zokongoletsa, zida zingapo zimatha kuphatikizidwa molimba, zomwe zimapangitsa mtengo wotsika komanso kudalirika kwambiri. Ndizitsulo zolimba kwambiri zachitsulo. Zipangizo zonse za misomali ya kubowola mchira imagawika chitsulo ndi chitsulo chosapanga dzimbiri, ndi mitundu yambiri yazinthu zina zinayi,φ 5.5× 20 mamilimitaφ 5.5× 135 mamilimita φ 6.3× 25 mamilimitaφ 6.3× Mamilimita 300. Kugwiritsa ntchito kwambiri magawo osiyanasiyana ndi zida. Mfundo zotsatirazi ndizo zomwe zimapangidwa ndi msomali wa mchira: 1. Ili ndi kulimba kwabwino: SUS410 yokhala ndi mpweya wocheperako imagwiritsidwa ntchito ndipo ukadaulo wothandizira kutentha umatengedwa kuti upewe kusweka komwe kumayamba chifukwa chakulimba mkatikati mwa msomali. 2. dzimbiri kukana 3. Kuwoneka kowala komanso kokongola: Pamaso pa msomali wa kubowola mchira ndi choyera, ndipo mutu wake ndi wowala ngati galasi. 4. Mphamvu Zapamwamba: Pambuyo pa chithandizo cha kutentha, kuuma kwapamwamba kwa msomali wa mchira kumatha kufika pamwamba pa HV580-HV750, potero kumaliza njira yolimbitsa ya kudziponyera ndi kudzipopera mano mwachangu komanso nthawi imodzi. Limbikitsani nthawi ndikuwongolera bwino ntchito. 5. Mtengo wabwino komanso mtengo wotsika
