Ithrekhi yerabha iyingxenye yokuhamba yohlobo lwesiseshi enenombolo ethile yezintambo zensimbi nezensimbi ezishumekwe ebhandeni lenjoloba.

Amathrekhi erabha angasindizinezinzuzo ezilandelayo:
(1) Ngokushesha
(2) Umsindo ophansi
(3) Ukudlidliza okuncane
(4) Amandla amakhulu okudonsa
(5) Umonakalo omncane endaweni yomgwaqo
(6) Ukucindezela okuncane komhlaba
(7) Umzimba ulula ngesisindo

1. Ukulungiswa kokushuba

(1) Ukulungiswa kokushuba kunomthelela omkhulu empilweni yesevisi yeithrekhi yerabha yase-chinas. Ngokuvamile, abakhiqizi bemishini bazokhombisa indlela yokulungisa emiyalweni yabo. Umfanekiso ongezansi ungasetshenziswa njengereferensi evamile.

(2) Amandla okucindezela axege kakhulu, okuholela kulokhu: [A] iqembu . [B] Isondo lomhlahlandlela elithwala umthwalo ligibela amazinyo. Ezimweni ezimbi kakhulu, i-pulley esekelayo kanye ne-car plate kuzokwenwa, okubangele ukuba i-ayoni ewumgogodla iwe. Uma ugibela igiya, i-tension yendawo iphezulu kakhulu futhi intambo yensimbi iphukile. [C] Into eqinile ilunywa phakathi kwesondo lokushayela nesondo lokuqondisa, futhi intambo yensimbi iphukile.

(3) Uma amandla e-tension aqine kakhulu, ithrekhi izokhiqiza ukushuba okukhulu, okuholela ebudeni, ukushintsha kwephimbo, nokucindezela okuphezulu kwendawo ethile, okubangela ukuguga okungavamile kwe-ayina emaphakathi nesondo lokushayela. Ezimweni ezimbi kakhulu, i-iron ewumgogodla izophuka noma Ixhumeke ngamadrayivu agugile.

2. Ukukhethwa kwendawo yokusebenza

(1) Izinga lokushisa elisebenzayo lamathrekhi enjoloba ngokuvamile liphakathi kuka -25 no +55°C.

(2) Amakhemikhali, uwoyela wenjini, nosawoti ophuma emanzini olwandle kuzosheshisa ukuguga komzila. Ithrekhi kufanele ihlanzwe ngemva kokusetshenziswa endaweni enjalo.

(3) Izindawo zomgwaqo ezinezingqimba ezicijile (njengezinsimbi, amatshe, njll.) zingabangela ukuhlukumezekaithrekhi yenjoloba.

(4) Imiphetho yomgwaqo, izintambo noma ukugandaywa ngendlela engalingani kuzodala imifantu kwiphethini yokunyathela ohlangothini oluphansi lonqenqema lwethrekhi. Intambo yensimbi ingaqhubeka isetshenziswa uma imifantu enjalo ingalimazi intambo yensimbi.

(5) Imigwaqo ewubhuqu namatshe izodala ukuguga ngaphambi kwesikhathi kwendawo yenjoloba lapho ihlangana namasondo athwala umthwalo, yenze imifantu emincane. Ezimweni ezimbi kakhulu, umswakama uyangena, okwenza ukuba i-iron ewumgogodla iwe futhi kuphuke ucingo lwensimbi.
