Cov ntawv txiav uas siv rau ntawm lub tshuab txiav tsuas yog hlau (lossis carbide) thiab pob zeb diamond sib tsoo discs, tab sis lawv qhov ntau thiab tsawg yog txiav txim siab nrog lub tshuab txiav, yog li koj tuaj yeem nrhiav cov tshuab txiav thiab lawv cov hniav txiav. Ntev npaum li koj muab cov qauv ntawm lub tshuab txiav, tus neeg muag khoom yuav sau tag nrho cov hlau pom cov hniav lossis cov hniav sib tsoo rau koj xaiv, uas tuaj yeem hloov pauv dawb.
1. Ua ntej, ua kom cov ciaj ntswj nrog lub qhov ntawm qhov kho qhov thaiv ntawm lub tshuab txiav thiab loosen nws counterclockwise.
2. Nws yuav tsum raug sau tseg ntawm no tias muaj lub pob me me tom qab lub tshuab txiav. Lub pob no yuav tsum tau nias kom unscrew lub txiav, txwv tsis pub nws yuav tsis tau unscrewed.
3. Tom qab loosening, tshem tawm qhov ruaj khov ntawm lub tshuab txiav thiab cov txiav qub.
4. Tom qab ntawd txhim kho cov hniav txiav tshiab thiab ua kom nruj rau kev txhim kho thaiv. Tsis txhob hnov qab tias lub pob nyob tom qab tseem yuav tsum tau nias.
5. Thaum kawg, kev hloov ntawm kev sib tsoo ntawm lub tshuab nqa pob zeb txiav ua tiav.
