Kev tshuaj xyuas cov khoom tawg-pov thawj hluav taws xob

1. Xyuas kom huv si ntawm cov khoom siv hluav taws xob tawg thiab nws qhov chaw nyob ze, tsis muaj cov khib nyiab obstructive.

2. Paub meej tias qhov ruaj khov fixation ntawm Cov khoom siv hluav taws xob tawg, tshawb xyuas qhov chaw kaw tsis raug, nruj screws, thiab tsis muaj corrosion.

3. Txheeb xyuas qhov ruaj khov ntawm cov khoom siv hluav taws xob nkag, intactness ntawm seals (suav nrog ntau cov kab txuas nkag), thiab ruaj ntseg kev sib txuas.

4. Tshawb xyuas kev ncaj ncees ntawm cov hauv av hlau rau cov khoom tawg-pov thawj, kuaj xyuas corrosion, kev tshem tawm, thiab tsis muaj kev puas tsuaj steel hlau ntawm armored cables.

5. Ntsuas qhov kev ntseeg tau ntawm kev sib cuam tshuam cov txheej txheem ntawm cov khoom siv hluav taws xob tawg.

6. Xyuas kom cov kab ib ntus thiab cov khoom siv ntawm qhov chaw ua raws li cov qauv pov thawj tawg.

7. Txheeb xyuas qhov kev ua haujlwm ib txwm muaj ntawm cov khoom siv hluav taws xob tawg, nrog kev ua haujlwm tsis zoo li tam sim no, hluav taws xob, siab, thiab kub nyob rau hauv ntau yam permissible.

8. Kos cov thawv sib txuas, cov khoom siv nkag, cais cov thawv ntim khoom, thiab cov kav dej hloov tau raws li cov qauv kev tawg-pov thawj.
