Ubunzima obuphantsi kunye nokuzinza komatshini kusenza sikwazi ukusebenzisa iindawo eziphakamileyo ezipakishweyo ngaphandle kokuxhasa ukupakisha okuphakathi.Umthamo ophezulu werhasi kunye namazinga okuhamba kwamanzi, ukuhamba kodonga oluphantsi kakhulu kunye novakalelo oluphantsi kungcoliseko.Ukuba amakhonkco okuhamba okuphezulu athatha indawo yokupakisha eqhelekileyo yenqaba, ngoko ke amazinga okuhamba kwiikholamu ezikhoyo anokwandiswa kakhulu okanye ukusetyenziswa kwamandla kunokunciphisa kakhulu.
Ugqithiso oluphezulu kunye nokuhanjiswa okulungileyo, ngokukodwa, ukwahlula ukusebenza kakuhle kusagcina ukungaguquguquki ngaphakathi kuluhlu lomthamo omkhulu womoya. Umphezulu wokupakisha lunyango olukhethekileyo, olunophawu lwepropathi elungileyo yokumanzisa kwaye luzele ngakumbi lulwelo lwerhasi; luzele ngakumbi ngokudibana nerhasi. kunye nolwelo, ukuhla koxinzelelo oluphantsi, indawo enkulu engenanto, ukuguquguquka okukhulu, ukusetyenziswa kwamandla aphantsi, Ukuhanjiswa okugqwesileyo ngakumbi ekupakishweni kwenqaba, njl.
