Isetshenziselwa ngokukhethekile ukulungisa inkinobho yezingwegwe namabhande akhethekile ezicathulweni zokuqwala izintaba, izicathulo zokuzivocavoca nezicathulo zomshwalense wabasebenzi, njll.
1. Umshini onama-servo motors, ukuvikelwa kwemvelo kuthule kakhulu, ukusebenza okuzinzile.
2.Ukuphakela okuzenzakalelayo zombili izingxenye zenkinobho yehhuku enewasha ephansi.
3. Ama-opharetha akusadingeki ukuthi abeke amahhuku mathupha ngaphambi kokuwalungisa.
4. Ukuphakela okuzenzakalelayo kanye ne-riveting yazo zombili izingxenye zenkinobho ye-hook enewasha ephansi kuqinisekisa ukuphepha nokusebenza kahle okuphezulu komsebenzi.
