Raws li ib qho tseem ceeb ntawm cov khoom siv rau kev thauj khoom hauv cov haujlwm, lub tsheb ua kom zoo dua thiab cov kev saib xyuas ncaj qha thiab cov neeg ua haujlwm muaj kev nyab xeeb. Cov hauv qab no piav qhia kev ceev faj txog kev tsav tsheb, chaw thau khoom, thauj khoom, thiab txij nkawm.
1. Ua ntej -} kev kuaj xyuas
Before starting, thoroughly inspect the vehicle's condition, including tire pressure, braking system, lights, signals, and hydraulics. Nco ntsoov tias cov tawv tov tig kom dawb, tsis muaj leej twg nrog cov suab nrov. Tsis tas li, tshawb xyuas theem dej hauv lub taub dej thiab lubricating roj lubricating kom ntseeg tau tias cov khoom siv tau zoo.
2. Chaw thau khoom thiab thauj cov lus qhia tshwj xeeb
Thaum thauj khoom pob zeb ua, tswj cov nqi pub noj raws li cov tais nruas lub peev xwm kom tsis txhob overloading. Tswj kev ceev tsis tu ncua thaum thauj khoom, qeeb thaum tig thiab nce thiab nce toj los tiv thaiv kev hloov pauv ntawm lub zog nqus uas tuaj yeem ua rau pob zeb. Cov nruas lub nruas yuav tsum tig mus txuas ntxiv ntawm qhov nrawm nrawm (feem ntau 3-6 rpm) txhawm rau tiv thaiv cov qhob caj dab lossis solidification. Thaum muaj kev caij tsheb ntev ntev, tesually tig lub nruas txhua 10-15 feeb.
3. Kev tiv thaiv thiab tu
Thaum tuaj txog ntawm lub hom phiaj, ua ntej ua kom cov khoom tsis muaj chaw nyob tiaj thiab tawv, ces tig lub tshuab tov khoom (feem ntau 8 {12 rpm) kom ua tiav kev tsis tuaj yeem. Tom qab kev txwv tsis pub, kom huv si huv si sab hauv thiab sab nraud ntawm lub tshuab tov khoom, tshwj xeeb tshaj yog cov ntsaws rooj sib tw, kom tiv thaiv tau ib qho kev ua haujlwm tawv thiab cuam tshuam rau kev siv tom ntej. Thaum tu, xyuam xim rau lub kaum sab xis ntawm cov dej dav hlau siab los tiv thaiv kev puas tsuaj rau cov hluav taws xob.
4. Kev tu ncua
Tom qab ua lag luam txhua hnub, tshuaj xyuas cov roj qib hydraulic, siv tawv nruj, thiab cov ntsia kub nruj; ntub cov kabmob thiab cov sib kis tau sib kis txhua lub lim tiam; thiab ua ib lub hlis tshuaj kuaj hluav taws xob txhua hli ntawm cov hluav taws xob thiab cov tshuab hydraulic. Thaum lub sijhawm ncua ntawm tsis -}}}}}}}}}}}} Txhua cov xeb ntawm lub nruas thiab ua cov ntawv pov thawj}} ua pov thawj ntawm cov hlau.
Cov txheej txheem ua haujlwm nruj rau cov txheej txheem kev ua haujlwm thiab cov tsev tu neeg tuaj yeem txuas ntxiv kev pabcuam lub neej ntawm lub neej kev nyab xeeb thaum ua kom muaj kev nyab xeeb. Cov tsav tsheb yuav tsum tau txais kev cob qhia kev ua haujlwm ib txwm los txhim kho lawv cov lus teb kev kub ceev.
