311,2mm (12 1/4″) Chidutswa chobowolera chokhala ndi zidutswa za polycrystalline, chokhala ndi nozzles za hydraulic, chokhala ndi masamba 5, chodulira cha m'mimba mwake cha 19 mm, chokhala ndi thupi lachitsulo lobowolera miyala yapakatikati.

Chobowola cha 311.2mm (12 1/4″) chimagwira ntchito bwino kwambiri pobowola miyala yapakatikati. Zidutswa zake za polycrystalline zimapereka kuuma kwapadera komanso kukana kuwonongeka, kuonetsetsa kuti ntchito yayitali komanso magwiridwe antchito odulira nthawi zonse. Ma nozzle a hydraulic amachotsa bwino zinyalala za miyala, kuteteza kutsekeka ndikusunga liwiro la kubowola. Ndi masamba 5, imagawa mphamvu yodulira mofanana, kuchepetsa kugwedezeka ndikuwonjezera kukhazikika. M'mimba mwake wa 19mm wodulira umathandizira kuchotsa zip, pomwe chitsulo chimapereka mphamvu zambiri zomangira kuti zipirire mikhalidwe yovuta ya miyala. Zonsezi pamodzi, zimathandizira kubowola bwino, kuchepetsa nthawi yogwira ntchito, ndikuwonetsetsa kuti ntchito yodalirika ikugwira ntchito m'miyala yapakatikati.
