Le ncwadi yobuchwepheshe ihloselwe abaphathi bemishini abangochwepheshe, ochwepheshe bokuthenga, kanye nabasebenzi bokulungisa emisebenzini yezimayini. Imininingwane kanye nezincomo kusekelwe ezindinganisweni zemboni kanye nedatha yomkhiqizi etholakalayo ngesikhathi sokushicilela. Wonke amagama omkhiqizi, izinombolo zezingxenye, kanye nezimpawu zamamodeli kusetshenziselwa izinjongo zokuhlonza kuphela. Njalo bheka imibhalo yemishini kanye nochwepheshe bezobuchwepheshe abafanelekayo ukuze uthole izinqumo eziqondene nesicelo.
