Ukwehluleka kwevalvu yokuphepha kubangelwa kakhulu ukwakheka okungafanele, ukukhiqizwa, ukukhethwa noma ukusetshenziswa. Uma la maphutha engasuswa ngesikhathi, azothinta ukusebenza kahle kanye nokuphila kwesevisi yevalvu, futhi awakwazi ngisho nokudlala indima ekuvikelweni kokuphepha. Amaphutha avamile kanye nezindlela zokususa yilezi ezilandelayo:
1. Ukuvuza
Ngaphansi kwengcindezi evamile yokusebenza kwemishini, ukuvuza okungaphezu kwezinga elivumelekile kwenzeka phakathi kwediski yevalvu kanye nobuso bokuvala besihlalo sevalvu. Isizathu siwukuthi: kukhona ukungcola phakathi kwediski yevalvu kanye nobuso bokuvala besihlalo sevalvu. I-wrench yokuphakamisa ingasetshenziswa ukuvula ivalvu izikhathi eziningana ukuze kuhlanzwe ukungcola; Ubuso bokuvala bonakele. Kufanele bulungiswe ngokugaya noma ngokugaya ngemva kokujika ngokwezinga lomonakalo; Induku yevalvu iyagoba, ithambeke noma i-lever kanye ne-fulcrum kuyaphambuka, ukuze umongo wevalvu kanye nediski yevalvu kuhambisane kabi. Hlanganisa kabusha noma shintsha; Ukuqina kwentwasahlobo kunciphisa noma kulahlekelwa ukuqina.
Kumelwe kuthathwe izinyathelo ezinjengokufaka esikhundleni sesiphethu kanye nokulungisa ingcindezi yokuvula.
2. Ungavuli uma ingcindezi echaziwe ifinyelelwe
Isizathu salokhu ukuthi ingcindezi engaguquki ayinembile, futhi ukucindezelwa kwesipilingi noma indawo yesando esindayo kufanele kulungiswe; Idiski inamathele esihlalweni sevalvu. Ivalvu yokuphepha kufanele ihlolwe njalo ngokukhishwa komoya ngesandla noma ngokukhishwa kwamanzi; I-lever yevalvu yokuphepha yohlobo lwe-lever inamathele noma isando esindayo siyanyakaziswa. Indawo yesisindo kufanele ilungiswe futhi i-lever kufanele ihambe ngokukhululeka.
3. Ukuvula ngaphansi kwengcindezi ethile
Isizathu esiyinhloko ukuthi ingcindezi engaguquki ayilungile; Intwasahlobo iyaguga futhi ukuqina kwayo kwehla. Qinisa kahle isikulufu sokulungisa noma usishintshe intwasahlobo.
