Kwengeza ukuvulwa kwezinhlangothi; i-air inlet kanye nendawo yokulungisa ephakathi, ithuthukisa indlela yokulungisa yesikhwama sokuhlunga, ivumela ukusakazeka komoya othulile, inciphisa ukugezwa kwesikhwama sokuhlunga ngokugeleza komoya, kulula ukushintsha isikhwama futhi uhlole isikhwama, futhi ukunciphisa i-headroom ye-workshop, Inezici zomthamo omkhulu wokucubungula igesi, ukusebenza kahle kokuhlanza okuphezulu, ukusebenza okuthembekile okusebenzayo, isakhiwo esilula, ukugcinwa okuncane, njll. Kufanelekile ngokukhethekile ukubamba uthuli oluncane nolomile olungenayo i-fibrous. Imishini yefomu ekhethekile nayo ingenziwa ngezifiso, futhi abasebenzisi banga-oda ngokuya ngezidingo zabo.
