1. Cov cuab yeej ntawm CNC txiav tshuab yuav tsum muaj kev ntseeg tau ruaj khov, thiab txhua yam khoom siv hluav taws xob xws li lub cev, lub thawv tswj, thiab ntshav ntshav lub zog ntawm CNC txiav tshuab yuav tsum muaj kev ntseeg ruaj khov.
2. Khaws lub cev thiab khaub ncaws kom qhuav;
3. Thaum txiav cov ntaub ntawv, tsis txhob khaws cov khoom ua haujlwm thiab cov khoom pov tseg;
4. Tsis txhob siv lub pob qhov rooj hloov nrog tes ntub kom tiv thaiv hluav taws xob poob;
5. Ua kom qhov loj thiab hom ntawm cov cables raws li cov lej hluav taws xob hauv zos;
6. Thaum siv lub cuab yeej, thov tsis txhob sawv ntsug, zaum lossis pw saum qhov ntub;
7. Nco ntsoov xyuas seb puas muaj txheej txheej sab nraud ntawm lub hwj chim puas (muaj qhov pheej hmoo kis tau cov xov hlau). Tsis txhob siv lub cuab yeej yog tias lub hwj huam qaum puas. Yog tias lub hwj huam qaum puas ntsoog, hloov tam sim ntawd.
8. Yog tias lub hau npog ntshav tsis tau teeb tsa, thov tsis txhob siv cov ntshav ntshav. Cov kab hluav taws xob nthuav tawm yog qhov txaus ntshai heev.
9. Txheeb xyuas lub teeb nrig. Yog tias lub hwj huam qaum puas los yog tawg, hloov nws.
10. Muab cov cua hloov mus rau phab ntsa thiab kev pov hwm sib xws rau cov cuab yeej siv. Qhov kev hloov no tso cai rau tus neeg teb xov tooj kom tua lub zog thaum muaj xwm ceev;
11. Ua ntej hloov cov khoom siv hluav taws xob, tshem tawm lub hwj chim thiab tos tsawg kawg 2 feeb. Tua lub hwj chim tom qab hloov chaw;
12. Tshawb xyuas ntau zaus thiab tswj cov hlua ntawm CNC txiav tshuab. Yog tias nws puas, nws yuav tsum tau hloov lossis muab pov tseg ua ntej siv cov cuab yeej siv;
13. Tsis txhob' tsis hla lossis luv-Circuit fais fab fuse;
14. Ua ntej yuav qhib lub hwj huam hluav taws xob npog rau kev saib xyuas, tshem tawm lub hwj chim tseem ceeb, tos 5 feeb, thiab cia lub capacitor tso tawm ua ntej mus.
15. Thov tsis txhob siv hluav taws xob los tshuaj xyuas cov xov hlau lossis hloov cov khoom siv hluav taws xob, txwv tsis pub koj yuav raug hluav taws xob lossis raug mob.
