● Umbala awulungile.
● Geza i-fade yamanzi, ukugeza okujwayelekile izikhathi ezingu-10.
● Usayizi wephethini awuhambisani nesampula yekhasimende.
● Ukubekezelelana akuvunyelwe, kuvuze okumhlophe (okuphrintiwe okumhlophe kuyanyakaza).
● Okunamathelayo kukonke ukunwetshwa okungu-0.2mm, unqenqema lwepulasitiki lukhulu kuno-0.25mm noma ngaphezulu, lukhulu kakhulu.
● Iphethini engalungile, nemidwebo enikezwe ikhasimende ayihambisani, iphethini ayilungile.
● Ukungcola, amaphethini noma amaphethini eduze kokudlulisa okushisayo kufanele kusetshenziswe endaweni yefilimu enokungcola okusobala ngaphandle kwephethini.
