Nyob rau theem tom ntej, nws raug nquahu kom pib sib sau cov ncej. Lub tes tsho yuav tsum tau muab tso rau ntawm lub hauv paus ncej, thiab tsuas yog tom qab ntawd tag nrho cov qauv tuaj yeem ntsia tau rau hauv nws qhov chaw.
Nyob ntaiv
Ua ntej lub sheathing ntawm cov ntaiv ntawm cov hlau ncej yog tsim, koj tuaj yeem ua tauua haujlwm los txhim kho nws. Ua li no, thaj tsam qis ntawm lub khib tuaj yeem ua kom tiav. Tom qab cov kauj ruam tau teeb tsa, lawv yuav tsum tau teeb tsa ntawm lub kaum sab xis xav tau thiab ua ke siv cov racks loj. Tam sim no lub nto yuav tsum tau npaj.
