9. Qetello
Litiiso tsa mochini li bapala karolo ea bohlokoa ts'ebetsong ea indasteri ka ho matlafatsa ts'epahalo ea lisebelisoa le ho thibela ho lutla ho kotsi. Ho utloisisa mefuta ea bona, lisebelisoa le lits'ebetso ho lumella liindasteri ho ntlafatsa ts'ebetso le ho fokotsa litšenyehelo tsa tlhokomelo. Ka tsoelopele e ntseng e tsoela pele, litiiso tsa mochini li tla tsoela pele ho fetoha, ho fihlela litlhoko tsa lits'ebetso tsa sejoale-joale tsa indasteri.
Ka ho kenya ts'ebetsong mekhoa e metle ea ho khetha, ho kenya le ho lokisa, liindasteri li ka eketsa nako ea bophelo ea litiiso tsa mechine, ho netefatsa hore li sebetsa hantle le tse sireletsehileng.
