Kuwongolera kwanzeru kutentha, mpweya wokhazikika wopanda chisanu, kutsitsimuka kwanthawi yayitali;
Compressor Brand, wokhazikika utakhazikika, kusunga zakudya zakuthupi ndi madzi osavuta kutaya;
Zonse-mkuwa firiji chubu, mofulumira firiji liwiro ndi kukana dzimbiri;
Kugwiritsa ntchito pansi populumutsa madzi, chitsulo chosapanga dzimbiri, chopanda dzimbiri;
Zoyenera zochitika zosiyanasiyana, malo odyera otentha, masitolo a nkhumba, masitolo atsopano, ndi zina zotero.
Kugulitsa kwachindunji kwafakitale, kopanda nkhawa pambuyo pogulitsa.
