Kev ua haujlwm txawv txav yog qhov teeb meem tseem ceeb. Yog tias cov cuab yeej nquag muaj kev vibrations lossis suab nrov thaum lub sijhawm ua haujlwm, lossis yog tias lub cev muaj zog thauj khoom tam sim no hloov pauv ntau dhau qhov qub, qhov no feem ntau yog ib qho kev qhia ntawm cov khoom siv sab hauv los yog lubrication tsis txaus. Tsis tas li ntawd, xyuam xim rau qhov kub thiab txias; Kev nyeem ntawv ruaj khov siab dua 70 degrees Celsius warrants xim.
Kev tawm tswv yim ua haujlwm kuj tseem tuaj yeem qhia txog teeb meem. Yog tias koj hnov cov kauj ruam hnyav, nyuaj rov qab mus rau qhov chaw, lossis yog tias lub vijtsam kov tsis pom lossis ua haujlwm tsis zoo, tej zaum yuav muaj teeb meem nrog cov khoom siv hluav taws xob lossis cov khoom sib kis. Tsis tas li ntawd, qhov tsis sib xws los yog cov ntawv tsis sib xws hauv cov ntawv yob rov qab kuj tseem cuam tshuam nrog cov khoom siv.
Kev tshuaj xyuas txhua hnub tuaj yeem tiv thaiv teeb meem ua ntej lawv tshwm sim. Ua ntej pib lub tshuab txhua hnub, xyuas tag nrho cov ntsiab lus lubrication rau cov dej ntws thiab xyuas kom cov roj qib txaus. Thaum lub sijhawm ua haujlwm, saib xyuas cov khoom siv pneumatic rau huab cua xau thiab hydraulic system kom ua haujlwm zoo. Tom qab ua tiav cov haujlwm, tam sim ntawd ntxuav cov ntaub ntawv thiab cov roj stains kom cov khoom huv si. Tsis tu ncua xyuas qhov hnav ntawm cov iav, chains, thiab lwm yam khoom, thiab ntxiv lossis hloov cov roj lubricating raws li xav tau, kuj tseem ceeb heev.
