E latela molao-motheo o reng "Ho tšepahala, ho sebetsa ka thata, ho sebetsa ka thata, ho na le mekhoa e mecha" ho fumana litharollo tse ncha kamehla. E nka litebello, katleho e le katleho ea eona ea botho. Ha re theheng bokamoso bo atlehileng ka matsoho bakeng sa Seamless Carbon Steel Fluid Pipe, Hona joale re thehile lebitso le nang le boikarabelo har'a bareki ba bangata. Boleng le moreki hangata ke lintho tseo re li batlang kamehla. Ha re ikitlaelletse ho thusa ho etsa litharollo tse betere haholo. Lebella tšebelisano ea nako e telele le melemo ea bobeli! Ho fihlela hajoale thepa ea rona e se e rometsoe Europe bochabela, Bochabela bo Hare, Boroa-bochabela, Afrika le Amerika Boroa joalo-joalo. Re na le thekiso le theko ea litsebi tsa 13years tsa Isuzu lapeng le mose ho maoatle le beng ba lisebelisoa tsa morao-rao tsa elektroniki tsa Isuzu. Re hlompha mosuoe-hlooho oa rona oa Botšepehi khoebong, e tlang pele tšebeletsong 'me re tla etsa sohle seo re ka se khonang ho fa bareki ba rona thepa ea boleng bo holimo le tšebeletso e babatsehang.
