Ukusebenzisa umshini Wokwehlisa uqhwaku ukuze uqhubeke nokusika uqhwaku lwenkukhu kuyingxenye ebalulekile yemboni yesimanje yenkukhu enezinzuzo zayo eziyinhloko ezihlanganisa:

1. Ngokuyisisekelo ukuvimbela ukwenzeka kwenkukhu ukupecking.
2. Ukunciphisa ukumoshakala kokudla okubangelwa ukulwa kwezinkukhu.
3. Ukunciphisa ukusetshenziswa kwamandla enkukhu.
4. Ukuthuthukisa indawo yokuzalanisa nokwandisa ukudla ngokusebenzisa ukusebenza kahle.

Ukusika uqhwaku ngendlela efanele kungasiza abalimi ukuthi bakhulise umkhiqizo ngendlela efanele kanti ukusika uqhwaku okungafanele noma ukungasikwa kungabangela ukukhula okungathandeki kokuzalanisa amatshwele nezikhukhukazi ezizalelayo.

Namuhla, ubuchwepheshe bokusika uqhwaku abukabanga ukunaka okukhulu kwabalimi ngesikhathi sokukhiqiza kwangempela. Ukufa okuphezulu, ukukhula okuntekenteke, ukungafanani kahle kanye nokuncipha kokukhiqizwa kwamaqanda okubangelwa ukusika uqhwaku okungafanele kuletha ukulahlekelwa kwezomnotho okungadingekile kubalimi, ngaleyo ndlela ukuthuthukiswa kwekhwalithi yokusika uqhwaku kuba iphuzu elibalulekile embonini yokulima izinkukhu.

Ngemuva kokunqunywa uqhwaku, ukudla kwenkukhu kuzoba ngaphansi ngo-3% kunenkukhu ngaphandle kokusikwa uqhwaku, futhi izinga lokulutheka lokupequlula amaqanda ngesikhathi sokubekela lizokwehla kakhulu.
