● Ngati chopakiracho chiyenera kugwiritsidwa ntchito ndi makina opopera ndodo, nthawi zambiri zimakhala zofunidwa kuti chubucho chiyikidwe mwamphamvu. Kusankha kwapaketi kuyenera kuchitidwa kuti izi zitheke.

Zokonda Makasitomala.

Ziyenera kuzindikirika kuti nthawi zambiri, mitundu ingapo ya mapaketi amatha kugwiritsidwa ntchito bwino pakuyika komweko. Nthawi zambiri, wopakira amatha kusankhidwa ndi wogwiritsa ntchito chifukwa adachita bwino poigwiritsa ntchito m'mbuyomu.

Zomwe zili pamwambazi ndizofotokozera posankha paketi. Vigor ali ndi zaka zambiri pamakampani amafuta ndi gasi ndipo akudzipereka kuyika ndalama mu R&D kuti awonetsetse kuti Vigor ikhoza kupereka mayankho apamwamba kwambiri kwa makasitomala athu. Opaka kuchokera ku Vigor amapangidwa ndikupangidwa pogwiritsa ntchito miyezo ya API 11D, ndipo akhala akugwiritsidwa ntchito m'munda kunyumba ndi kunja ndipo akhala akudziwika ndi makasitomala.
