Ukutshintshwa kwepani yeoyile yegiya yingxaki enkulu?
Nokuba kukulungiswa ngokutsha, okanye qhagamshelana nabathengisi abaqhelekileyo bendawo:
1. Ingxaki yokuvuza kweoyile kwipani yeoyile inokuba nkulu okanye incinci ngokwendlela evuza ngayo. Kucetyiswa ukuba unikele ingqalelo engakumbi kwinqanaba leoyile yesithuthi sakho ngaphambi kokuba usombulule ingxaki ukuqinisekisa ukuba ukuvuza okugqithisileyo kuya kuchaphazela ukusebenza kwesithuthi okuqhelekileyo;
2, ukuba yi-1, ngokubanzi kukuguga kwetywina yeoyile, kwaye kulungile ukutshintsha itywina yeoyile entsha;
3. Ukuba yi-2, ngokuqhelekileyo yiwasher yebholithi ephukileyo okanye isikrufu sityibilikile. Ukuba iwasher yaphukile, ungacela entsha.
4, kukho iindlela ezintathu zonyango: yongeza isitywina se-sealant, yandisa kwakhona umngxuma wentambo, yongeza i-bolt entsha. Tshintsha ipani yeoyile (eli xabiso liphezulu, ezinye iivenkile ze-4S zinokucebisa oku);
