(1) Spreader nyob rau hauv chav kawm ntawm kev siv, xws li qhov tshwm sim ntawm kev sib hloov ntawm cov ntsia hlau tsis hloov pauv lossis tsis nyob hauv qhov chaw, yuav tsum xyuas cov txiv ntoo hloov kho, thiab tom qab ntawd xyuas cov hauv qab no:

① Yog tias lub caij nplooj ntoos hlav nro ntawm lub pawl puas lawm, yog tias nws puas lawm, nws yuav tsum tau hloov;

② Yog hais tias lub tshuab kis tau tus mob yog jammed, xws li daig, nws yog lubricated tsis zoo, ces cov roj lubricating (los yog roj) yuav tsum tau ntxiv rau kev sib txuas ntawm lub tshuab kis tau tus mob. Yog hais tias tus taw qhia tus pin yog nruj heev, yuav tsum tsim nyog rau xoob txiv ntseej. Yog tias qhov kev sib txuas yog xoob, lub raj xa hluav taws xob lossis lwm yam bar deformation, nws yuav tsum raug kho;

③ tsis muaj caij nplooj ntoos hlav stretch me me dhau, yog tias me me, koj yuav tsum ua kom luv luv lub caij nplooj ntoos hlav tsis txuas ntev ntawm txoj hlua.

(2) kev siv cov khoom sib kis yuav tsum yog los tiv thaiv cov lus qhia ntawm qhov taw qhia phaj xim tawm. Thaum pom, yuav tsum tau sau cov cim thawj ntawm cov xim.

(3) Rau txoj hlua ntawm cov khoom sib kis, yuav tsum tau tu raws sij hawm thiab coated nrog lubricating roj los yog roj, tshwj xeeb tshaj yog cov hlua hlau dabtsi yog khoov.

(4) Rau cov khoom siv tseem ceeb, cov nplhaib, cov hlua khi, cov pob ntseg thiab cov hlua khi, nyob rau hauv ib txwm siv ntawm kev tshem tawm, tsawg kawg txhua 3 lub hlis los xyuas ib zaug, tsis muaj qhov tawg thiab deformation loj.

(5) Txhua lub khob roj, suav nrog cov khob roj ntawm lub tshuab ratchet, roj khob ntawm cov zawv zawg vaj tse thiab cov khob roj rau lub thawv kaw, yuav tsum tau ntim cov roj lubricating raws li kev siv.

(6) feem ntau xyuas cov hlua daim npav yog xoob, lub caij nplooj ntoos hlav tsis muaj qhov ncab ntau dhau, pom tias qhov teeb meem hauv lub sijhawm.

(7) txhua tus kis yuav tsum tsis pub tshaj qhov ntsuas qhov hnyav, lub caij nplooj ntoos hlav tsis tuaj yeem yuav tsum tsis txhob ncab ntau dhau.

(8) lifting txheej txheem yuav tsum yog ib tug du lifting, kom tsis txhob kis tau tus kab mob thiab cranes los yog lwm yam khoom siv, xws li kev cuam tshuam ntawm ib leeg thiab deformation.
