5. Siv fais fab fais fab
1 Thaum siv lub tawb me ntsis, nws yog ib qhov tsim nyog siv lub ciaj ntswj ntawm hom.
2 Ua ntej pib hloov qhov xyaum hloov, qhov yuav tsum muab coj los ua kom tiav.
3 Thaum lub laum no tsis siv los yog thaum hloov qhov xyaum, thawj zaug tua lub zog thiab muab tso rau hauv.
4 Cov taub me ntsis yuav tsum raug tshem tawm thawj zaug thaum nws raug kaw.
5 Ua siab ceev rau lub pob tshab, qhov kev quab yuam yuav tsum muaj qhov qis, quab yuam ntau dhau yuav ua rau cov tho me ntsis los yog txo qhov khiav ceev ntawm kev siv lub pob. Tsawg me me, kev siv me ntsis yog ib qho yooj yim hnav. Thaum drilling ceev ceev, lub siab yuav tsum yog lub teeb kom nws tau pierced smoothly.
6 Thaum muab cov khoom me me los ua kom tiav, cov khoom siv hauv tsev kawm ntawv yuav tsum tau kho, thiab tsis txhob tuav tes los ntawm tes.
7 Tsis txhob hnav khaub ncaws xoob, khi, phuam qhwv caj dab, lossis hnab looj tes thaum siv lub tshuab fais fab. Cov plaub hau ntev yuav tsum raug khi.
6. Portable hniav sib tsoo:
1 Kuaj xyuas seb cov hniav sib tsoo puas lawm, txoj kev sib hloov tsis yog lawm, qhov sib tsoo pob zeb tsis kauj, thiab tus ceev xwm yog xoob ua ntej siv.
2 Hnav cov iav los yog lub npog ncauj thaum lub sib tsoo.
3 Koj lossis lwm tus yuav tsum tsis txhob muaj kev cuam tshuam ntawm txoj kev sib tsoo ntawm txoj hlua sib tsoo kom tsis txhob ya ya lossis txawb cov khoom tawg los ntawm kev poob.
4 Tom qab cov hniav sib tsoo tawm lawm, txoj kev sib tsoo hlau tsis tuaj yeem yuav av. Tsis tas li ntawd, txoj hlua sib tsoo tsis tuaj yeem nres nyob rau hauv txoj kev no.
7. Fais fab hlau
1 Lub taub hau ntawm cov kav hlau yuav tsum ceev kom huv thiab tsis khib nyiab.
2 Tsis txhob coj mus ceev kom tsis txhob muaj cov hlau nplaum hluav taws xob paug.
3-transistor tivthaiv zoo li siv ib cov kav hlau ntawm 30 rau 40 watts.
4 Lub kav hlau yuav tsum muab tso rau hauv lub bracket los yog ntawm rwb thaiv tsev thaum tsis siv.
5 Lub taub hau ntawm cov kav hlau ntxiab yog kub heev. Tshem nyiaj kom tsis txhob kub hnyiab lossis hluav taws kub ze ntawm cov khoom ntim.
