Kev tu txhua hnub ntawm cov khoom siv kho dej khib nyiab yog qhov tseem ceeb rau kev ua haujlwm ruaj khov, ua kom cov cuab yeej siv tau ntev, thiab lav kev ua raws li cov dej ntws tawm.
Cov yam ntxwv tseem ceeb ntawm kev saib xyuas cov cuab yeej suav nrog lubrication, tiv thaiv corrosion, tu, kho, thiab hloov khoom siv.
(1) Kev saib xyuas niaj hnub: Qhov no suav nrog kev saib xyuas sab nraud xws li kev tu cov cuab yeej, tshuaj xyuas, thiab lubrication, ua los ntawm tus neeg teb xov tooj ua ib feem ntawm kev ua haujlwm.
(2) Kev saib xyuas cov khoom hnav: Qhov no suav nrog kev tu, lubrication, tu, thiab tshuaj xyuas. Qhov no yuav tsum tau ua raws li kev taw qhia ntawm cov neeg ua haujlwm saib xyuas, suav nrog kev tshem tawm, hloov kho cov ntsiab lus tseem ceeb, thiab kev ua haujlwm ntawm cov khoom siv.
(3) Kev Kho: Qhov no yog qhov loj - kev npaj kho, feem ntau yog 1 mus rau 1 npaug ntawm tus qauv rau cov chaw kho dej khib nyiab, tshwm sim txhua 3 xyoos. Nws suav nrog kev hloov thiab kho cov cuab yeej siv, tshuaj xyuas thiab kho qhov tseem ceeb, thiab ua kom cov cuab yeej ua tau raws li cov qauv kev qhia.
