Emhlabeni wezinto ezisetshenziswayo ezisindayo, igama elithi "okusetshenziswayo" ngokuvamile lingaphakamisa ukukhathazeka mayelana nesikhathi sokuphumula kanye nokulungiswa okungalindelekile. Nokho, imakethe yesimanje for certified ama-excavators aphethwe ngaphambili iwushintshe kakhulu lo mbono. Umshini ogunyaziwe osetshenzisiwe uklanywe ngenqubo yokuvuselela eqinile ukuze ulethe ukwethembeka kwezimbangi—futhi ngezindlela ezithile ezingokoqobo, ngisho nokufana—kwemodeli entsha.
Lokhu kwethembeka okuseduze kuvela kuhlelo oluhlelekile, olunamaphuzu amaningi lokunikeza izitifiketi olwenziwa abakhiqizi noma abathengisi bezinga eliphezulu. Ngokungafani nendali evamile esetshenzisiwe, i-excavator ephethwe ngaphambili eqinisekisiwe yenza ukuhlolwa okuphelele okungashiyi isistimu enkulu ingahloliwe. Lokhu kuhlanganisa ukuhlolwa okuningiliziwe kwe-undercarriage, amasistimu asebenza ngamanzi, ukusebenza kwenjini, ubuqotho besakhiwo, nazo zonke izingxenye ze-elekthronikhi ezibalulekile. Noma iyiphi ingxenye engahlangabezani nezimfuneko eziqinile zomkhiqizi wangempela iyakhandwa noma ifakwe izingxenye zangempela ze-OEM. Le nqubo ivuselela ngempumelelo impilo yomshini ewumgogodla womshini.
Ngalé kokuhlolwa nokulungiswa, isitifiketi ngokuvamile sihlanganisa ukuthuthukiswa okuyinhloko okuthuthukisa ukwethembeka. Lokhu ngokuvamile kuhilela uketshezi olugcwele kanye noshintsho lwesihlungi, ukushintsha zonke izinto ezigqokwayo njengama-seal namapayipi, futhi ngezinye izikhathi ngisho nokubuyekeza isofthiwe ibe inguqulo yakamuva. Umshini awuhlanzwa nje kuphela; yenziwe kabusha ngokucophelela ukuze ibe yizinga lokusebenza elichaziwe.
Mhlawumbe into ebaluleke kakhulu evala igebe lokuthembeka iwaranti. I-excavator eqinisekisiwe cishe njalo iza newaranti elinganiselwe efanekisela lokho okunikezwa ezintweni ezintsha, ezimboza izingxenye ezinkulu zenkathi ethile noma inombolo yamahora okusebenza. Lesi siqinisekiso siwubufakazi obunamandla bokwethemba komthengisi esimweni somshini futhi sinikeza umnikazi ukuthula kwengqondo okufanayo nokuthenga okusha. Iguqula ukuthengwa kwegembu kube yimali evikelekile.
Okokugcina, umshini oqinisekisiwe uza nombiko womlando oqinisekisiwe. Abathengi bathola imibhalo egcwele yesevisi yangaphambilini, amahora okusetshenziswa, nanoma yikuphi ukulungiswa okuqediwe, okuqeda ukungaqiniseki okukhungethe ukuthengisa okusetshenzisiwe okuyimfihlo.
Sengiphetha, isitifiketi esiqinisekisiwe i-excavator esetshenzisiwe I- inikeza ukwethembeka eduze nokusha ngoba isuswa ezingozini ngokuhlelekile. Ngephrothokholi yesitifiketi eqinile, ukulungiswa kabusha kwengxenye yangempela, iwaranti ebanzi, nokukhanyela okuphelele, iletha ukusebenza okungabikezelwa. Ku-opharetha oqaphela izindleko, imele impambana-mgwaqo efanele yokuqina okuqinisekisiwe, inani elivikelwe, nokusebenza okuthembekile.
