1. Nco ntsoov xyuas qhov nro ntawm cov saw saw.Thov tua lub cav thiab hnav cov hnab looj tes tiv thaiv thaum kuaj xyuas thiab kho.Thaum qhov nro yog qhov tsim nyog, cov saw hlau tuaj yeem rub los ntawm tes thaum cov saw hlau tau dai rau ntawm qhov qis ntawm daim ntawv qhia.
2. Yuav tsum muaj roj me ntsis txaws ntawm cov saw hlau.Cov saw lubrication thiab roj qib hauv cov roj tank yuav tsum tau kuaj xyuas txhua zaus ua ntej ua haujlwm.Chains yuav tsum tsis txhob ua haujlwm yam tsis muaj lubrication, vim tias kev ua haujlwm nrog cov saw hlau qhuav yuav ua rau muaj kev puas tsuaj rau cov cuab yeej txiav.
3. Tsis txhob siv cov roj qub.Cov roj qub tsis tuaj yeem ua tau raws li qhov xav tau lubrication thiab tsis haum rau cov saw lubrication.
4. Yog tias cov roj qib hauv cov roj tank tsis txo qis, nws yuav yog tias cov roj lubrication tsis ua haujlwm.Cov saw lubrication yuav tsum tau kuaj xyuas thiab cov roj Circuit Court yuav tsum tau kuaj xyuas.Ib qho khoom siv roj tsis zoo kuj tuaj yeem tshwm sim los ntawm lub vijtsam lim dej.Lub lubricating roj npo nyob rau hauv cov roj tank thiab twj tso kua mis txuas kab yuav tsum tau muab ntxuav los yog hloov.
5. Tom qab hloov thiab txhim kho cov saw tshiab, cov saw saw xav tau 2 mus rau 3 feeb ntawm lub sijhawm ua haujlwm.Tshawb xyuas cov saw nro tom qab tawg thiab hloov kho yog tias tsim nyog.Ib txoj saw tshiab yuav tsum muaj kev sib zog ntau dua li cov saw hlau uas tau siv rau ib ntus.Cov saw saw yuav tsum tau txuas mus rau sab qis ntawm cov ntawv qhia bar thaum nws txias, tab sis cov saw saw tuaj yeem txav mus rau sab sauv qhia bar ntawm tes.Rov nro cov saw yog tias tsim nyog.Thaum qhov kub thiab txias ua haujlwm tau mus txog, cov saw saw nthuav dav thiab sags me ntsis, thiab kev sib txuas sib txuas ntawm qhov qis ntawm daim ntawv qhia tsis tuaj yeem raug tshem tawm ntawm cov saw zawj, txwv tsis pub cov saw yuav dhia thiab cov saw yuav tsum tau rov tensioned.
6. Cov saw hlau yuav tsum tau so tom qab ua haujlwm.Chains poob qis thaum lawv txias, thiab cov saw hlau uas tsis xoob tuaj yeem ua rau lub crankshaft thiab bearings puas.Yog hais tias cov saw yog tensioned nyob rau hauv kev ua hauj lwm tej yam kev mob, cov saw yuav shrinks thaum nws txias, thiab yog hais tias cov saw nruj heev, lub crankshaft thiab bearings yuav puas.
