Ma granite ndi miyala ya laimu amafuna mphamvu yokhazikika, ndipoS250 kubowola miyala ya pneumaticimachitadi zimenezo. Kapangidwe kake ka mpweya kamalimbitsa chibowocho, pomwe mphamvu yake yabwino kwambiri yogwirira ntchito imadula bwino zinthu zokhuthala.

Opanga makontrakitala ayamikira S250 chifukwa chakukonza mwachangu komanso moyo wautali wa gawo, zomwe zimapangitsa kuti ikhale ndalama yolimba yogwiritsidwa ntchito kwambiri. Kaya ndi mabowo obowola kapena maziko, S250 imatsimikizira zotsatira zosalala, zachangu, komanso zodalirika.

Chomwe chimasiyanitsa S250 pamalopo ndi momwe imakhudzira kagwiridwe kake ka ntchito. Ogwira ntchito akale amanena kuti kuchepa kwakukulu kwa "bit-bind" - kugwedezeka kosasangalatsa kwa chitsulo chobowolera m'dzenje. Kugunda kosalekeza kwa chobowolera, kuphatikiza ndi kuthamanga kwa mpweya wabwino, kumatsimikizira kuti zidutswazo zimachotsedwa bwino komanso kuti dzenje likhale lolunjika. Izi sizongokhudza liwiro lokha; koma ndi za kulondola. Mabowo owongoka amachititsa kuti ziphulike bwino, kusweka bwino, ndipo pamapeto pake, miyala yabwino kwambiri ipange popanda kutaya zinyalala zambiri.

Kulimba kwake sikungotanthauza chabe. S250 ili ndi pisitoni yopangidwa ndi carburised ndi silinda yolimba, zinthu zomwe zasankhidwa kuti zipirire fumbi lolimba lomwe limapangidwa ndi granite ndi limestone. Izi zikutanthauza kuti nthawi yogwirira ntchito imakhala yayitali mpaka 30% kuposa mitundu ina, chinthu chofunikira kwambiri pakugwira ntchito nthawi zambiri. Kwa oyang'anira migodi omwe amafufuza phindu lake, S250 imapereka yankho lomveka bwino: mphamvu yosalekeza komanso nthawi yochepa yogwirira ntchito yokonza zinthu ikufanana ndi kubweza ndalama mwachangu, kusintha pambuyo pa kusintha kwakukulu.
