11. Thaum ntxiv cov khoom siv rau txoj siv conveyor, yuav tsum yog cov khoom sib xws txhawm rau tiv thaiv kev ntxiv cov khoom siv ntau dhau, siv txoj siv sia tuag, cuam tshuam rau kev nyab xeeb ntawm kev siv tshuab.
12. Ua ntej yuav tsum nres, peb yuav tsum xub tso tseg tsis pub noj mus rau hauv lub conveyor, thiab tos kom tag nrho cov ntaub ntawv ntawm txoj siv yuav tsum tau unloaded ua ntej yuav tsum tau signaling. Thaum ntau tshaj ib txoj siv conveyor nyob rau hauv series, qhov kev txiav txim nres yog los ntawm kev pub noj kawg mus rau qhov kawg ntawm qhov chaw nres.
13. Tom qab nres, xyuas cov khoom siv conveyor, ua tib zoo saib xyuas kev ua haujlwm zoo, ua tib zoo sau cov ntaub ntawv khiav, tom qab ntawd ua haujlwm zoo ntawm kev xa cov haujlwm.
14. Hauv kev ua haujlwm ntawm cov tshuab, cov xwm txheej hauv qab no yuav tsum nres thaum muaj xwm ceev:
(1) Tus kheej raug mob lossis tuag tshwm sim.
(2) Txoj siv tawv yog tawg, tawg lossis rub tawm.
(3) Txoj siv tawv yog jammed.
(4) Lub conveyor ncej yog tilted, vau los yog loj deformed.
(5) Lub cev muaj zog haus luam yeeb, kub kub.
(6) Cov iav tawg tawg, tawg ncej.
(7) Mechanical bearings, ncej pobzeb hlawv.
(8) Ib qho ntawm ntau txoj siv conveyor txuas nrog hauv series tsis ua haujlwm thiab nres.
(9) Lwm yam xwm txheej, thiab lwm yam.
