Ngokuvamile, yisikulufu sokhuni esinesihloko somunwe, amazinyo awugqinsi nokuthungwa okuqinile, kanye nengxube ye-aluminium nepulasitiki.Uhlobo olukhethekile lwesikulufu esizishayayo esisetshenziselwa ukuvula izintambo ezimbotsheni zensimbi lubizwa ngokuthi umpompi.
Izikulufo zokuzishaya zensimbi engeyona eyensimbi noma ethambile, azidingi ukushaya imbobo engezansi kanye nokuthepha;Izikulufu zokuzishaya zikhonjiwe, ukuze "ziziphephethe ngokwakho";Izikulufu ezijwayelekile ziyisicaba - zinekhanda futhi zinogqinsi olufanayo.
Isikulufu sokuzishaya ngokwakho sisho ukuthi: bhoboza izimbobo ngaphandle kokuthinta imbobo, isikulufu kanye nomehluko ojwayelekile, ikhanda likhonjiwe, ibanga lezinyo likhulu ngokuqhathaniswa, kanye nokuthepha ngocingo lwamahhala lwe-chip kufana nje, akukwazi ukuthepha ngokuqondile, insimbi nepulasitiki ngokuvamile zisebenzisa le ndlela.
Ingahlanganiswa kundaba, incike emculweni wayo, izohlanganiswa umzimba "kampompi - drill, cindezela, ingcindezi" ngaphandle kwentambo ehambisanayo, ukuze isondelane.
